TheIntel Core microarchitecture(previously known as theNext-Generation Micro-Architecture) is a multi-coreprocessormicroarchitectureunveiled byIntelin Q1 2006. It is based on theYonahprocessor design and can be considered an iteration of theP6 microarchitecture, introduced in 1995 withPentium Pro. The high power consumption and heat intensity, the resulting inability to effectively increaseclock speed, and other shortcomings such as the inefficient pipeline were the primary reasons for which Intel abandoned theNetBurst microarchitectureand switched to completely different architectural design, delivering high efficiency through a small pipeline rather than high clock speeds. It is worth noting that the Core microarchitecture never reached the clock speeds of the Netburst microarchitecture, even after moving to the 45nmlithography.

The first processors that used this architecture were code-namedMerom,Conroe, andWoodcrest; Merom is for mobile computing, Conroe is for desktop systems, and Woodcrest is for servers and workstations. While architecturally identical, the three processor lines differ in the socket used, bus speed, and power consumption. Mainstream Core-based processors are brandedPentium Dual-CoreorPentiumand low end brandedCeleron; server and workstation Core-based processors are brandedXeon, while desktop and mobile Core-based processors are branded asCore 2. Despite their names, processors sold asCore Solo/Core DuoandCorei3/i5/i7 do not actually use the Core microarchitecture and are based on theEnhanced Pentium Mand newerNehalem/Sandy Bridge/Haswellmicroarchitectures, respectively.

Features[edit]

The Core microarchitecture returned to lowerclock ratesand improved the usage of both available clock cycles and power when compared with the precedingNetBurst microarchitectureof thePentium 4/D-branded CPUs.^[1]The Core microarchitecture provides more efficient decoding stages, execution units,caches, andbuses, reducing thepower consumptionof Core 2-branded CPUs while increasing their processing capacity. Intel's CPUs have varied widely in power consumption according to clock rate, architecture, and semiconductor process, shown in theCPU power dissipationtables.

Like the last NetBurst CPUs, Core based processors feature multiple cores and hardware virtualization support (marketed asIntel VT-x), as well asIntel 64andSSSE3. However, Core-based processors do not have theHyper-Threading Technologyfound in Pentium 4 processors. This is because the Core microarchitecture is a descendant of theP6 microarchitectureused by Pentium Pro, Pentium II, Pentium III, and Pentium M.

The L1 cache size was enlarged in the Core microarchitecture, from 32KB on Pentium II/III (16 KB L1 Data + 16 KB L1 Instruction) to 64 KB L1 cache/core (32 KB L1 Data + 32 KB L1 Instruction) on Pentium M and Core/Core 2. It also lacks an L3 Cache found in the Gallatin core of the Pentium 4 Extreme Edition, although an L3 Cache is present in high-end versions of Core-based Xeons. Both an L3 cache and Hyper-threading were reintroduced in theNehalem microarchitecture.

Roadmap[edit]

Intel CPU core roadmaps fromNetBurstandP6toCannonlake

Technology[edit]

While the Core microarchitecture is a major architectural revision it is based in part on thePentium Mprocessor family designed by Intel Israel.^[2]ThePenrynpipelineis 12–14 stages long^[3]— less than half ofPrescott's, a signature feature of wide order execution cores. Penryn's successor,Nehalemhas 16 pipeline stages.^[3]Core'sexecution unitis 4 issues wide, compared to the 3-issue cores ofP6,Pentium M, and 2-issue cores ofNetBurstmicroarchitectures. The new architecture is a dual core design with linkedL1 cacheand sharedL2 cacheengineered for maximumperformance per wattand improved scalability.

One new technology included in the design isMacro-Ops Fusion, which combines twox86instructions into a singlemicro-operation. For example, a common code sequence like a compare followed by a conditional jump would become a single micro-op.

Other new technologies include 1 cycle throughput (2 cycles previously) of all 128-bit SSE instructions and a new power saving design. All components will run at minimum speed, ramping up speed dynamically as needed (similar to AMD'sCool'n'Quietpower-saving technology, as well as Intel's ownSpeedSteptechnology from earlier mobile processors). This allows the chip to produce less heat, and consume as little power as possible.

Intel Core microarchitecture.

For most Woodcrest CPUs, thefront side bus (FSB)runs at 1333MT/s; however, this is scaled down to 1066MT/s for lower end 1.60 and 1.86GHz variants.^[4][5]The Merom mobile variant was initially targeted to run at a FSB of 667MT/s while the second wave of Meroms, supporting 800MT/s FSB, were released as part of the Santa Rosa platform with a different socket in May 2007. The desktop-oriented Conroe began with models having an FSB of 800MT/s or 1066MT/s with a 1333MT/s line officially launched on July 22, 2007.

The power consumption of these new processors is extremely low—average use energy consumption is to be in the 1–2 watt range in ultra low voltage variants, withthermal design powers(TDPs) of 65 watts for Conroe and most Woodcrests, 80 watts for the 3.0GHz Woodcrest, and 40 watts for the low-voltage Woodcrest. In comparison, an AMDOpteron875HE processor consumes 55 watts, while the energy efficientSocket AM2line fits in the 35 wattthermal envelope(specified a different way so not directly comparable). Merom, the mobile variant, is listed at 35 watts TDP for standard versions and 5 watts TDP for Ultra Low Voltage (ULV) versions.^{[citation needed]}

Previously, Intel announced that it would now focus on power efficiency, rather than raw performance. However, atIDFin the spring of 2006, Intel advertised both. Some of the promised numbers were:

20% more performance for Merom at the same power level (compared toCore Duo)
40% more performance for Conroe at 40% less power (compared toPentium D)
80% more performance for Woodcrest at 35% less power (compared to the originaldual-core Xeon)

Processor cores[edit]

The processors of the Core microarchitecture can be categorized by number of cores, cache size, and socket; each combination of these has a unique code name and product code that is used across a number of brands. For instance, code name "Allendale" with product code 80557 has two cores, 2 MB L2 cache and uses the desktop socket 775, but has been marketed as Celeron, Pentium, Core 2 and Xeon, each with different sets of features enabled. Most of the mobile and desktop processors come in two variants that differ in the size of the L2 cache, but the specific amount of L2 cache in a product can also be reduced by disabling parts at production time. Wolfdale-DP and all quad-core processors except Dunnington QC are multi-chip modules combining two dies. For the 65nm processors, the same product code can be shared by processors with different dies, but the specific information about which one is used can be derived from the stepping.

Conroe/Merom (65 nm)[edit]

Main article:Conroe (microprocessor)

The original Core 2 processors are based around the same dies that can be identified asCPUIDFamily 6 Model 15. Depending on their configuration and packaging, their code names are Conroe (LGA 775, 4 MB L2 cache), Allendale (LGA 775, 2 MB L2 cache), Merom (Socket M, 4 MB L2 cache) and Kentsfield (Multi-chip module, LGA 775, 2x4MB L2 cache). Merom and Allendale processors with limited features can be found inPentium Dual CoreandCeleronprocessors, while Conroe, Allendale and Kentsfield also are sold asXeonprocessors.

Additional code names for processors based on this model areWoodcrest(LGA 771, 4 MB L2 cache),Clovertown(MCM, LGA 771, 2×4MB L2 cache) andTigerton(MCM,Socket 604, 2×4MB L2 cache), all of which are marketed only under the Xeon brand.

Conroe-L/Merom-L[edit]

The Conroe-L and Merom-L processors are based around the same core as Conroe and Merom, but only contain a single core and 1 MB of L2 cache, significantly reducing production cost and power consumption of the processor at the expense of performance compared to the dual-core version. It is used only in ultra-low voltage Core 2 Solo U2xxx and in Celeron processors and is identified as CPUID family 6 model 22.

Penryn/Wolfdale (45 nm)[edit]

Main article:Penryn (microarchitecture)

In Intel'sTick-Tockcycle, the 2007/2008 "Tick" was the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. In Core 2 processors, it is used with the code names Penryn (Socket P), Wolfdale (LGA 775) and Yorkfield (MCM, LGA 775), some of which are also sold as Celeron, Pentium and Xeon processors. In the Xeon brand, theWolfdale-DPandHarpertowncode names are used for LGA 771 based MCMs with two or four active Wolfdale cores.

The chips come in two sizes, with 6 MB and 3 MB L2 cache. The smaller version is commonly called Penryn-3M and Wolfdale-3M as well as Yorkfield-6M, respectively. The single-core version of Penryn, listed as Penryn-L here, is not a separate model like Merom-L but a version of the Penryn-3M model with only one active core.

Dunnington[edit]

TheXeon "Dunnington"processor (CPUID Family 6, model 30) is closely related to Wolfdale but comes with six cores and an on-chip L3 cache and is designed for servers with Socket 604, so it is marketed only as Xeon, not as Core 2.

		X7460	6	16 MB		130 W

Steppings[edit]

The Core microarchitecture uses a number ofsteppings, which unlike previous microarchitectures not only represent incremental improvements but also different sets of features like cache size and low power modes. Most of these steppings are used across brands, typically by disabling some of the features and limiting clock frequencies on low-end chips.

Steppings with a reduced cache size use a separate naming scheme, which means that the releases are no longer in alphabetic order. Additional steppings have been used in internal and engineering samples, but are not listed in the tables.

Many of the high-end Core 2 and Xeon processors useMulti-Chip Modulesof two or three chips in order to get larger cache sizes or more than two cores.

Steppings B2/B3, E1 and G0 of model 15 (cpuid 06fx) processors are evolutionary steps of the standard Merom/Conroe die with 4MiB L2 cache, with the short-lived E1 stepping only being used in mobile processors. Stepping L2 and M0 are the "Allendale" chips with just 2MiB L2 cache, reducing production cost and power consumption for low-end processors.

The G0 and M0 steppings improve idle power consumption in C1E state and add the C2E state in desktop processors. In mobile processors, all of which support C1 through C4 idle states, steppings E1, G0, and M0 add support for the Mobile Intel 965 Express (Santa Rosa) platform withSocket P, while the earlier B2 and L2 steppings only appear for theSocket Mbased Mobile Intel 945 Express (Napa refresh) platform.

The model 22 stepping A1 (cpuid 10661h) marks a significant design change, with just a single core and 1MiB L2 cache further reducing the power consumption and manufacturing cost for the low-end. Like the earlier steppings, A1 is not used with the Mobile Intel 965 Express platform.

Steppings G0, M0 and A1 mostly replaced all older steppings in 2008. In 2009, a new stepping G2 was introduced to replace the original stepping B2.^[6]

In the model 23 (cpuid 01067xh), Intel started marketing stepping with full (6MiB) and reduced (3MiB) L2 cache at the same time, and giving them identical cpuid values. All steppings have the newSSE4.1instructions. Stepping C1/M1 was a bug fix version of C0/M0 specifically for quad core processors and only used in those. Stepping E0/R0 adds two new instructions (XSAVE/XRSTOR) and replaces all earlier steppings.

In mobile processors, stepping C0/M0 is only used in the Intel Mobile 965 Express (Santa Rosa refresh) platform, whereas stepping E0/R0 supports the later Intel Mobile 4 Express (Montevina) platform.

Model 30 stepping A1 (cpuid 106d1h) adds an L3 cache as well as six instead of the usual two cores, which leads to an unusually large die size of 503mm2.^[7]As of February 2008, it has only found its way into the very high-end Xeon 7400 series (Dunnington).

The currently released Yorkfield XE model QX9770 (45nm with 1600FSB) currently has limited chipset compatibility - with only X38, P35 (WithOverclocking) and some high-performance X48 and P45 motherboards being compatible. BIOS updates are gradually being released to provide support for the new Penryn technology, and the new QX9775 is only compatible with D5400XS. The Wolfdale-3M model E7200 also has limited compatibility (at least the Xpress 200 chipset is incompatible)^{[citation needed]}.

Although a motherboard may have the required chipset to support Conroe, some motherboards based on the above mentioned chipsets do not support Conroe. This is because all Conroe-based processors require a new power delivery feature set specified inVoltage Regulator-Down (VRD) 11.0. This requirement is a result of Conroe's significantly lower power consumption, compared to the Pentium 4/D CPUs it is replacing. A motherboard that has both a supporting chipset and VRD 11 supports Conroe processors, but even then some boards will need an updatedBIOSto recognize Conroe's FID (Frequency ID) and VID (Voltage ID).

Synchronous memory modules[edit]

Unlike the previousPentium 4andPentium Ddesign, the Core 2 technology sees a greater benefit from memory runningsynchronouslywith theFront Side Bus(FSB). This means that for the Conroe CPUs with FSB of 1066MT/s, the ideal memory performance for DDR2 isPC2-8500. In a few configurations, usingPC2-5300instead of PC2-4200 can actually decrease performance. Only when going toPC2-6400is there a significant performance increase. While DDR2 memory models with tighter timing specifications do improve performance, the difference in real world games and applications is often negligible.^[8]

Optimally, the memory bandwidth afforded should match the bandwidth of the FSB, that is to say that a CPU with a 533MT/s rated bus speed should be paired with RAM matching the same rated speed, for example DDR2 533, or PC2-4200. A common myth^{[citation needed]}is that installing interleaved RAM will offer double the bandwidth. However, at most the increase in bandwidth by installing interleaved RAM is roughly 5–10%. TheAGTL+ PSB^{[dead link]}used by allNetBurstprocessors as well as current and medium-term (pre-QuickPath) Core 2 processors provide a 64-bit data path. Current chipsets provide for a couple of either DDR2 or DDR3 channels.

On jobs requiring large amounts of memory access, the quad-core Core 2 processors can benefit significantly^[9]from using aPC2-8500memory, which runs exactly the same speed as the CPU's FSB; this is not an officially supported configuration, but a number of motherboards offer it.

The Core 2 processor does not require the use of DDR2. While the Intel 975X and P965 chipsets require this memory, some motherboards and chipsets support both the Core 2 andDDRmemory. When using DDR memory, performance may be reduced because of the lower available memory bandwidth.

Chip errata[edit]

The Core 2memory management unit(MMU) in X6800, E6000 and E4000 processors does not operate to previous specificationsimplementedin previous generations ofx86hardware. This may cause problems, many of them serious security and stability issues, with existingoperating systemsoftware. Intel's documentation states that their programming manuals will be updated "in the coming months" with information on recommended methods of managing thetranslation lookaside buffer(TLB) for Core 2 to avoid issues, and admits that, "in rare instances, improper TLB invalidation may result in unpredictable system behavior, such as hangs or incorrect data."^[10]

Among the issues noted:

Non-executebit is shared across the cores.
Floating point instruction non-coherencies.
Allowed memory corruptions outside of the range of permitted writing for a process by running common instruction sequences.

IntelerrataAx39, Ax43, Ax65, Ax79, Ax90, Ax99 are said to be particularly serious.^[11]39, 43, 79, which can cause unpredictable behavior or system hang, have been fixed in recentsteppings.

Among those who have noted the errata to be particularly serious areOpenBSD'sTheo de Raadt^[12]andDragonFly BSD'sMatthew Dillon.^[13]Taking a contrasting view wasLinus Torvalds, calling the TLB issue "totally insignificant", adding, "The biggest problem is that Intel should just have documented the TLB behavior better."^[14]

Microsoft has issued update KB936357 to address the errata bymicrocodeupdate,^[15]with no performance penalty. BIOS updates are also available to fix the issue.

Key Terms[edit]

In Intel'sTick-Tockcycle, the 2007/2008 "Tick" was the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. In Core 2 processors, it is used with the code namesPenryn(Socket P), Wolfdale (LGA 775) and Yorkfield (MCM, LGA 775), some of which are also sold as Celeron, Pentium and Xeon processors. In the Xeon brand, theWolfdale-DPandHarpertowncode names are used for LGA 771 based MCMs with two or four active Wolfdale cores.

The chips come in two sizes, with 6 MB and 3 MB L2 cache. The smaller version is commonly called Penryn-3M and Wolfdale-3M as well as Yorkfield-6M, respectively. The single-core version of Penryn, listed as Penryn-L here, is not a separate model like Merom-L but a version of the Penryn-3M model with only one active core.

Processor cores[edit]

The processors of the Core microarchitecture can be categorized by number of cores, cache size, and socket; each combination of these has a unique code name and product code that is used across a number of brands. For instance, code name "Allendale" with product code 80557 has two cores, 2 MB L2 cache and uses the desktop socket 775, but has been marketed as Celeron, Pentium, Core 2 and Xeon, each with different sets of features enabled. Most of the mobile and desktop processors come in two variants that differ in the size of the L2 cache, but the specific amount of L2 cache in a product can also be reduced by disabling parts at production time. Wolfdale-DP and all quad-core processors except Dunnington QC are multi-chip modules combining two dies. For the 65nm processors, the same product code can be shared by processors with different dies, but the specific information about which one is used can be derived from the stepping.

In the model 23 (cpuid 01067xh), Intel started marketing stepping with full (6MiB) and reduced (3MiB) L2 cache at the same time, and giving them identical cpuid values. All steppings have the newSSE4.1instructions. Stepping C1/M1 was a bug fix version of C0/M0 specifically for quad core processors and only used in those. Stepping E0/R0 adds two new instructions (XSAVE/XRSTOR) and replaces all earlier steppings.

In mobile processors, stepping C0/M0 is only used in the Intel Mobile 965 Express (Santa Rosa refresh) platform, whereas stepping E0/R0 supports the later Intel Mobile 4 Express (Montevina) platform.

Model 30 stepping A1 (cpuid 106d1h) adds an L3 cache as well as six instead of the usual two cores, which leads to an unusually large die size of 503mm2.^[1]As of February 2008, it has only found its way into the very high-end Xeon 7400 series (Dunnington).

Nehalem/n??he?l?m/^[1]is thecodenamefor anIntelprocessormicroarchitecture, successor to theCore microarchitecture.^[2]Nehalem processors use the45 nmprocess. A preview system with two Nehalem processors was shown atIntel Developer Forumin 2007. The first processor released with the Nehalem architecture was the desktopCore i7,^[3]which was released in November 2008.

Nehalem, a recycled Intel code name, refers to an architecture that differs radically fromNetburst, while retaining some of the latter's minor features. Nehalem-based microprocessors use higher clock speeds and are more energy-efficient thanPenrynmicroprocessors.Hyper-threadingis reintroduced, along with a reduction in L2 cache size, as well as an enlarged L3 cache that is shared by all cores. Nehalem was replaced with theSandy Bridgemicroarchitecture, released in January 2011.

Performance and power improvements[edit]

It has been reported that Nehalem has a focus on performance, thus the increased core size.^[6]Compared to Penryn, Nehalem has:

10-25% more single-threaded performance / 20-100% moremultithreadedperformance at the same power level
30% lowerpower consumptionfor the sameperformance
Nehalem provides a 15–20% clock-for-clock increase in performance per core(average)

Overclocking is possible with Bloomfield processors and theX58chipset. Lynnfield processors use aPCHremoving the need for a northbridge chipset.^[7]

Nehalem processors incorporateSSE 4.2SIMDinstructions, adding 7 new instructions to the SSE 4.1 set in the Core 2 series. The Nehalem architecture reduces atomic operation latency by 50% in an attempt to eliminate atomic overhead .^[8]

Connection of theGPUinside the Westemere microarchitecture

Westmere(formerlyNehalem-C) is the name given to the32 nmdie shrinkofNehalem. The firstWestmere-based processors were launched on January 7, 2010 by Intel Corporation.

Westmere's feature improvements from Nehalem as reported:

Native six-core (Gulftown) and ten-core (Westmere-EX) processors.^[1]
A new set of instructions that gives over 3x the encryption and decryption rate ofAdvanced Encryption Standard(AES) processes compared to before.^[2]

Delivers seven new instructions (AES instruction setorAES-NI) that will be used by the AES algorithm. Also an instruction called PCLMULQDQ (seeCLMUL instruction set) that will perform carry-less multiplication for use in cryptography.^[3]These instructions will allow the processor to perform hardware-accelerated encryption, not only resulting in faster execution but also protecting against software targeted attacks.

Integrated graphics, added into the processor package (dual coreArrandaleandClarkdaleonly).
Improved virtualization latency.^[4]
New virtualization capability: "VMX Unrestricted mode support," which allows 16-bit guests to run (real mode and big real mode).
Support for "Huge Pages" of 1 GB in size.

Sandy Bridgeis thecodenamefor amicroarchitecturedeveloped byIntelbeginning in 2005 forcentral processing unitsin computers to replace theNehalemmicroarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under theCorebrand.^[1][2]

Sandy Bridge implementations targeted a32 nanometermanufacturing process based onplanar double-gate transistors.^[3]Intel's subsequent product, codenamedIvy Bridge, uses a22 nanometerprocess. TheIvy Bridgedie shrink, known in theIntel Tick-Tockmodel as the "tick", is based onFinFET(non-planar, "3D")tri-gate transistors. Intel demonstrated theIvy Bridgeprocessors in 2011.^[4]

Technology[edit]

Developed primarily by theIsraelbranch ofIntel, the codename was originally "Gesher" (meaning "bridge" inHebrew). The name was changed to avoid being associated with the defunctGesher political party;^[5]the decision was led by Ron Friedman, vice president of Intel managing the group at the time.^[1]Intel demonstrated a Sandy Bridge processor with A1steppingat 2GHzduring theIntel Developer Forumin September 2009.^[6]

Upgraded features from Nehalem include:

32KB data + 32KB instructionL1 cache(3clocks) and 256KBL2 cache(8clocks) per core.
Shared L3cache includes the processor graphics (LGA 1155).
64-bytecacheline size.
Two load/store operations perCPU cyclefor each memory channel.
Decodedmicro-operation cache(uop cache) and enlarged, optimizedbranch predictor.
Improved performance fortranscendental mathematics,AES encryption(AES instruction set), andSHA-1hashing.
256-bit/cycle ring bus interconnect between cores, graphics, cache and System Agent Domain.
Advanced Vector Extensions(AVX) 256-bit instruction set with wider vectors, new extensible syntax and rich functionality.
Intel Quick Sync Video, hardware support for video encoding and decoding.
Up to 8 physical cores or 16 logical cores throughHyper-threading.
Integration of the GMCH (integrated graphics and memory controller) and processor into a single die inside the processor package. In contrast, Sandy Bridge's predecessor,Clarkdale, has two separate dies (one for GMCH, one for processor) within the processor package. This tighter integration reduces memory latency even more.
A 14- to 19-stageinstruction pipeline, depending on the micro-operation cache hit or miss.^[7]

Translation lookaside buffersizes^[8][9]

ITLB	1st	128	8 / logical core	none
STLB	2nd	512	none	none

All translation lookaside buffers (TLBs) are 4-wayassociative.^[10]

Models and steppings[edit]

All Sandy Bridge processors with one, two, or four cores report the same CPUID model 0206A7h^[11]and are closely related. The stepping number can not be seen from the CPUID but only from the PCI configuration space. The later Sandy Bridge-E processors with up to eight cores and no graphics are using CPUIDs 0206D6h and 0206D7h.^[12]Ivy Bridge CPUs all have CPUID 0306A9h to date, and are built in four different configurations differing in the number of cores, L3 cache and GPU execution units.

Performance[edit]

The average performance increase, according to IXBT Labs and Semi Accurate as well as many other benchmarking sites, at clock to clock is 11.3% compared to the Nehalem Generation, which includes Bloomfield, Clarkdale, andLynnfieldprocessors.^[17]
Around twice the integrated graphics performance compared toClarkdale's(12EUscomparison).

Cougar Point chipset flaw[edit]

On January 31, 2011, Intel issued a recall on all 67-series motherboards due to a flaw in theCougar PointChipset.^[28]A hardware problem, in which the chipset's SATA-II ports may fail over time, cause failure of connection to SATA-II devices, though data is not at risk.^[29]Intel claims that this problem will affect only 5% of users over 3 years, however, heavier I/O workloads can exacerbate the problem.

Intel stopped production of flawed B2 stepping chipsets and began producing B3 stepping chipsets with the silicon fix. Shipping of these new chipsets started on 14 February 2011 and Intel estimated full recovery volume in April 2011.^[30]Motherboard manufacturers (such asASUSandGigabyte Technology) and computer manufacturers (such asDellandHewlett-Packard) stopped selling products that involved the flawed chipset and offered support for affected customers. Options ranged from swapping for B3 motherboards to product refunds.^[31][32]

Sandy Bridge processor sales were temporarily on hold, as one cannot use the CPU without a motherboard. However, processor release dates were not affected.^[33]After two weeks, Intel continued shipping some chipsets, but manufacturers had to agree to a set of terms that will prevent customers from encountering the bug.^[34]

Limitations[edit]

Overclocking[edit]

With Sandy Bridge, Intel has tied the speed of every bus (USB, SATA, PCI, PCI-E, CPU cores, Uncore, memory etc.) to a single internal clock generator issuing the basic100 MHzBase Clock (BClk).^[35]With CPUs being multiplier locked, the only way to overclock is to increase the BClk, which can be raised by only 5–7% without other hardware components failing. As a work around, Intel made available K/X-series processors, which feature unlocked multipliers; with a multiplier cap of 57 for Sandy Bridge.^[36]For the Sandy Bridge E platform, there is alternative method known as the BClk ratio overclock.^[37]

During IDF (Intel Developer Forum) 2010, Intel demonstrated an unknown Sandy Bridge CPU running stably overclocked at 4.9GHz on air cooling.^[38][39]

Chipset[edit]

Non-K edition CPUs can overclock up to four bins from its turbo multiplier. Referherefor chipset support.

vPro remote-control (Intel Insider)[edit]

Sandy and Ivy Bridge processors withvProcapability have security features that can remotely disable a PC or erase information from hard drives. This can be useful in the case of a lost or stolen PC. The commands can be received through 3G signals, Ethernet, or Internet connections. AES encryption acceleration will be available, which can be useful for video conferencing and VoIP applications.^[40][41]

Software development kit[edit]

With the introduction of the Sandy Bridge microarchitecture, Intel also introduced theIntel Data Plane Development Kit(Intel DPDK) to help developers of communications applications take advantage of the platform inpacket processingapplications, andnetwork processors.^[42]

Roadmap[edit]

Intel demonstrated theHaswellarchitecture in September 2011, released in 2013 as the successor toSandy BridgeandIvy Bridge.^[43]

Ivy Bridgeis thecodenamefor a line of processors based on the 22nm manufacturing process developed byIntel. The name is also applied more broadly to the22nmdie shrinkof theSandy Bridgemicroarchitecture based onFinFET("3D")tri-gate transistors, which is also used in theXeonandCore i7Ivy Bridge-EX(Ivytown),Ivy Bridge-EPandIvy Bridge-Emicroprocessors released in 2013.

Ivy Bridge processors are backwards compatible with the SandyBridge platform, but such systems might require a firmware update (vendor specific).^[1]In 2011, Intel released the 7-seriesPanther Pointchipsetswith integratedUSB 3.0to complement IvyBridge.^[2]

Volume production of IvyBridge chips began in the third quarter of 2011.^[3]Quad-coreand dual-core-mobile models launched on April 29, 2012 and May 31, 2012 respectively.^[4]Corei3 desktop processors, as well as the first 22nmPentium, were announced and available the first week of September, 2012.^[5]

Overview[edit]

The IvyBridge CPU microarchitecture is a shrink from SandyBridge and remains largely unchanged.

Notable improvements include:^[6][7]

22nmTri-gate transistor("3-D") technology (up to 50% less power consumption at the same performance level as 2-D planar transistors).^[8]
A new random number generator and theRdRandinstruction,^[9]codenamed Bull Mountain.^[10]

Ivy Bridge features and performance[edit]

The mobile and desktop IvyBridge chips also include significant changes over SandyBridge:

F16C(16-bit Floating-point conversion instructions).
RdRandinstruction (Intel Secure Key).
PCI Express 3.0support (not on Corei3 and ULV processors).^[11]
MaxCPU multiplierof 63 (57 for Sandy Bridge).^[12]
RAM support up to 2800MT/sin 200MHz increments.^[12]

Benchmark comparisons[edit]

Compared to Sandy Bridge:

3% to 5% increase in CPU performance when compared clock for clock^[21][22]
25% to 68% increase in integrated GPU performance.^[23]

Thermal performance and heat issues[edit]

Ivy Bridge's temperatures are reportedly 10°C higher compared to Sandy Bridge when overclocked, even at default voltage setting.^[24]Impress PC Watch, a Japanese website, performed experiments that confirmed earlier speculations that this is because Intel used a poor quality (and perhaps lower cost)thermal interface material(thermal paste, or "TIM") between the chip and theheat spreader, instead of thefluxlesssolder of previous generations.^[25][26][27]The mobile Ivy Bridge processors are not affected by this issue because they do not use a heat spreader between the chip and cooling system.

Enthusiast reports describe the TIM used by Intel as low-quality,^[27]and not up to par for a "premium" CPU, with some speculation that this is by design to encourage sales of prior processors.^[25]Further analyses caution that the processor can be damaged or void its warranty if home users attempt to remedy the matter.^[25][28]The TIM has much lowerthermal conductivity, causing heat to trap on the die.^[24]Experiments replacing this with a higher quality TIM or other heat removal methods showed a substantial temperature drop, and improvements to the voltages and clocking sustainable by IvyBridge chips.^[25][29]

Intel claims that the smaller die of IvyBridge and the related increase in thermal density is expected to result in higher temperatures when the CPU is overclocked; Intel also stated that this is as expected and will likely not improve in future revisions.^[30]

Models and steppings[edit]

All Ivy Bridge processors with one, two, or four cores report the same CPUID model 0x000306A9, and are built in four different configurations differing in the number of cores, L3 cache and GPU execution units.

Server processors[edit]

Additional high-end server processors based on the Ivy Bridge architecture, code named Ivytown, were announced September 10, 2013 at theIntel Developer Forum, after the usual one year interval between consumer and server product releases.^[39][40][41]The IvyBridge-EP processor line announced in September 2013 has up to 12 cores and 30MB third level cache, with rumors of Ivy Bridge-EX up to 15 cores and an increased third level cache of up to 37.5MB,^[42][43]although an early leaked lineup of Ivy Bridge-E included processors with a maximum of 6 cores.^[44]Both Core-i7 and Xeon versions are produced: the Xeon versions marketed asXeon E5-2600 V2act as drop-in replacements for the existing Sandy Bridge-EN and Sandy Bridge-EP based Xeon E5, and Core-i7 versions designated i7-4820K, i7-4930K, i7-4960X were released on September 10, 2013 remained compatible withX79andLGA2011hardware.^[43][45]

A new IvyBridge-EX line marketed asXeon E7 V2had no corresponding predecessor using the SandyBridge microarchitecture but instead followed the olderWestmere-EXprocessors.

Design[edit]

A Haswellwaferwith a pin for scale.

The Haswell architecture is specifically designed^[5]to optimize the power savings and performance benefits from the move toFinFET(non-planar, "3D") transistors on the improved 22nm process node.^[6]

Haswell has been launched in three major forms:^[7]

Desktop version (LGA1150 socket):Haswell-DT
Mobile/Laptop version (PGAsocket):Haswell-MB
BGAversion:

47W and 57W TDP classes:Haswell-H(For "All-in-one" systems, Mini-ITX form factor motherboards, and other small footprint formats.)
13.5W and 15W TDP classes (MCP):Haswell-ULT(For Intel's UltraBook platform.)
10W TDP class (SoC):Haswell-ULX(For tablets and certain UltraBook-class implementations.)

Notes[edit]

ULT =Ultra LowTDP; ULX =Ultra Low eXtremeTDP.
Only certain quad-core variants and BGA R-seriesSKUswill receive GT3 (Intel HD 5000, Intel Iris 5100), or GT3e (Intel Iris Pro 5200) integrated graphics. All other models will get GT2 (Intel HD 4X00) integrated graphics.^[8]See alsoIntel HD Graphicsfor more detailed specifications.
Due to low power requirements of tablet and UltraBook platforms, Haswell-ULT and Haswell-ULX will only be available in dual-core. All other versions will be available in dual- or quad-core variants.

Performance[edit]

Compared toIvy Bridge:

Approximately 8% bettervector processingperformance.^[9]
Up to 6% faster single-threaded performance.
6% faster multi-threaded performance.
Desktop variants of Haswell draw between 8% and 23% more power under load than Ivy Bridge.^[9][10][11]
A 6% increase in sequential CPUperformance(eight execution ports per core versus six).^[9]
Up to 20% performance increase over the integrated HD4000GPU(Haswell HD4600 vs Ivy Bridge's built-inIntel HD4000).^[9]
Total performance improvement on average is about 3%.^[9]
Around 15°C hotter than Ivy Bridge and unable to break 4.2GHz easily.^{[12][13][14][15][16][17]}

Features carried over from Ivy Bridge[edit]

A22nmmanufacturing process.
3Dtri-gate transistors.
Micro-operation cachecapable of storing 1.5Kmicro-operations(approximately 6KB in size).^[18]
A 14- to 19-stageinstruction pipeline, depending on the micro-operation cache hit or miss (has been working that way since the introduction ofSandy BridgeCPUs).^[18]
Mainstream variants are up to quad-core.^[19]
Native support fordual-channelDDR3memory,^[20]with up to 32GB ofRAMon LGA 1150 variants.
64KB (32KB Instruction + 32KB Data) L1 cache and 256KB L2 cache per core.^[21]
A total of 16PCI Express3.0 lanes.

New features[edit]

Wider Core: fourth ALU, third AGU, secondbranch predictionunit, deeper buffers, higher cache bandwidth, improved front-end andmemory controller
Haswell New Instructions^[22](HNI, includesAdvanced Vector Extensions 2(AVX2),gather,BMI1+BMI2, LZCNT andFMA3support).^[23]
The instruction decode queue, which holds instructions after they have been decoded, is no longer statically partitioned between the two threads that each core can service.^[18]
New sockets –LGA 1150for desktops and rPGA947 & BGA1364 for the mobile market.^[24]
Z97 (performance) and H97 (mainstream)chipsetsfor the Haswell Refresh andBroadwell, in Q2 2014.^[25]
New socket –LGA 2011-3with X99 chipset for the Enthusiast-Class Desktop Platform Haswell-E.^[26]
IntelTransactional Synchronization Extensions(TSX), on selected models.^[27]
Graphics support in hardware forDirect3D 11.1andOpenGL4.0.^[28]
DDR4for the enterprise/server variant (Haswell-EX).^[29]
DDR4for the Enthusiast-Class Desktop Platform Haswell-E.^[30]
Variable Base clock (BClk)^[31]likeLGA 2011.^[32]
There are four versions of the integrated GPU: GT1, GT2, GT3 and GT3e, where GT3 version has 40 execution units (EUs). Haswell's predecessor, Ivy Bridge, has a maximum of 16 EUs. GT3e version with 40 EUs and on-package 128MB of embedded DRAM (eDRAM), calledCrystal Well, is available only in mobile H-SKUsand desktop (BGA-only) R-SKUs. Effectively, this eDRAM is a Level 4 cache — shared dynamically between the on-die GPU and CPU, and serving as avictim cacheto the CPU's L3 cache.^{[33][34][35][36][37]}
Support forThunderbolttechnology and Thunderbolt 2.0.^[38]
Fully integratedvoltage regulator(FIVR), thereby moving some of the components frommotherboardonto the CPU.^[39][40][41]FIVR is implemented as a separate 13x8 mm on-package die, manufactured in90 nmprocess.^[42]
New advanced power-saving system.
37, 47, 57Wthermal design power(TDP) mobile processors.^[19]
35, 45, 65, 84, 95 and 130–140W (high-end, Haswell-E) TDP desktop processors.^[19]
15W TDP processors for theUltrabookplatform (multi-chip package likeWestmere)^[43]leading to reduced heat which results in thinner as well as lighter Ultrabooks, but performance level will be lower than the 17W version.^[44]
Shrink of thePlatform Controller Hub(PCH), from65 nmto32 nm.^[45]

Roadmap[edit]

Main article:Intel Tick-Tock

On September 10, 2013, Intel showcased the Broadwell 14nm processor in a demonstration at IDF. Intel CEOBrian Krzanichclaimed that the chip would allow systems to provide a 30 percent improvement in power use over theHaswellchips released in mid-2013.^[10]

On October 21, 2013, a leaked Intel roadmap indicated a late 2014 or early 2015 release of the K-series Broadwell on the LGA 1150 platform, in parallel with the previously announced Haswell refresh. This will coincide with the release of Intel's 9-series chipset, which may be required for Broadwell processors due to a change in power specifications for its LGA 1150 socket.^[11][12]

No new mobile roadmaps have yet leaked to clarify if mobile Broadwell will be available in 2014. A leaked slide shows Broadwell-E/EP/EX in 2015.^[13]

Bonnellis aCPU microarchitectureused byIntel Atomprocessors which can execute up to two instructions per cycle.^[1][2]Like many other x86 microprocessors, it translates x86 instructions (CISCinstructions) into simpler internal operations (sometimes referred to asmicro-ops, effectivelyRISCstyle instructions) prior to execution. The majority of instructions produce one micro-op when translated, with around 4% of instructions used in typical programs producing multiple micro-ops. The number of instructions that produce more than one micro-op is significantly fewer than theP6andNetBurstmicroarchitectures. In the Bonnell microarchitecture, internal micro-ops can contain both a memory load and a memory store in connection with anALUoperation, thus being more similar to the x86 level and more powerful than the micro-ops used in previous designs.^[3]This enables relatively good performance with only two integer ALUs, and without anyinstruction reordering,speculative executionorregister renaming. The Bonnell microarchitecture therefore represents a partial revival of the principles used in earlier Intel designs such asP5and thei486, with the sole purpose of enhancing theperformance per wattratio. However,Hyper-Threadingis implemented in an easy (i.e. low-power) way to employ the wholepipelineefficiently by avoiding the typical single thread dependencies.^[3]

First generation cores[edit]

Silverthorne microprocessor[edit]

On 2 March 2008, Intel announced a new single-core Atom Z5xx series processor (code-named Silverthorne), to be used inultra-mobile PCsandmobile Internet devices(MIDs), which will supersedeStealey(A100 and A110). The processor has 47 million transistors on a 25mm²die, allowing for extremely economical production (~2500 chips on a single 300mm diameter wafer).

An Atom Z500 processor's dual-thread performance is equivalent to its predecessor Stealey, but should outperform it on applications that can use simultaneousmultithreadingandSSE3.^[4]They run from 0.8 to 2.0GHz and have aTDPrating between 0.65 and 2.4W that can dip down to 0.01W when idle.^[5]They feature 32KB instruction L1 and 24KB data L1 caches, 512KB L2 cache and a 533MT/s front-side bus. The processors are manufactured in 45nm process.^[6][7]

Diamondville microprocessor[edit]

The Intel Atom N270

On 2 March 2008, Intel announced lower-power variants of the Diamondville CPU named Atom N2xx. It was intended for use in nettops and theClassmate PC.^[8][9][10]Like their predecessors, these are single-core CPUs with Hyper-Threading.

The N270 has a TDP rating of 2.5W, runs at 1.6GHz and has a 533MHz FSB.^[11]The N280 has a clock speed of 1.66GHz and a 667MHz FSB.^[12]

On 22 September 2008, Intel announced a new 64-bit dual-core processor (unofficially code-named Dual Diamondville) branded Atom 330, to be used in desktop computers. It runs at 1.6GHz and has a FSB speed of 533MHz and a TDP rating of 8W. Its dual core consists of two Diamondville dies on a single substrate.^[13]

During 2009,Nvidiaused the Atom 300 and their GeForce 9400M chipset on amini-ITXform factor motherboard for theirIonplatform.

First generation power requirements[edit]

The relatively low power Atom CPU was originally used with a cheaper, not so electricity-efficient chipset such as the Intel 945G

Although the Atom processor itself is relatively low-power for an x86 microprocessor, many chipsets commonly used with it dissipate significantly more power. For example, while the Atom N270 commonly used in netbooks through mid-2010 has a TDP rating of 2.5W, an Intel Atom platform that uses the 945GSE Express chipset has a specified maximum TDP of 11.8W, with the processor responsible for a relatively small portion of the total power dissipated. Individual figures are 2.5W for the N270 processor, 6W for the 945GSE chipset and 3.3W for the 82801GBM I/O controller.^{[14][11][15][16]}Intel also provides a US15WSystem Controller Hub-based chipset with a combined TDP of less than 5W together with the Atom Z5xx (Silverthorne) series processors, to be used in ultra-mobile PCs and MIDs,^[17]though some manufacturers have released ultra-thin systems running these processors (e.g. Sony VAIO X).

Initially, all Atom motherboards on the consumer market featured the Intel 945GC chipset, which uses 22 watts by itself. As of early 2009, only a few manufacturers are offering lower-power motherboards with a 945GSE or US15W chipset and an Atom N270, N280 or Z5xx series CPU.

Second generation cores[edit]

Pineview microprocessor[edit]

New Intel Atom N450 SLBMG 1.66GHz 512kB L2 BGA559

On 21 December 2009, Intel announced the N450, D510 and D410 CPUs with integrated graphics.^[18]The new manufacturing process resulted in a 20% reduction in power consumption and a 60% smaller die size.^[19][20]The IntelGMA 3150, a 45nm shrink of the GMA 3100 with no HD capabilities, is included as the on-die GPU. Netbooks using this new processor were released on 11 January 2010.^[19][21]The major new feature is longer battery life (10 or more hours for 6-cell systems).^[22][23]

This generation of the Atom was codenamed Pineview, which is used in the Pine Trail platform. Intel's Pine Trail-M platform utilizes an Atom processor (codenamed Pineview-M) andPlatform Controller Hub(codenamed Tiger Point). The graphics and memory controller have moved into the processor, which is paired with the Tiger Point PCH. This creates a more power-efficient 2-chip platform rather than the 3-chip one used with previous-generation Atom chipsets.^[24]

On 1 March 2010 Intel introduced the N470 processor,^[25]running at 1.83GHz with a 667MHz FSB and a TDP rating of 6.5W.^[26]

The new Atom N4xx chips became available on 11 January 2010.^[27]It is used innetbookandnettopsystems and includes an integrated single-channelDDR2memory controller and an integratedgraphics core. It also featuresHyper-Threadingand is manufactured on a 45nm process.^[28]The new design uses half the power of the older Menlow platform. This reduced overall power consumption and size makes the platform more desirable for use in smartphones and other mobile internet devices.

The D4xx and D5xx series support thex86-64bit instruction set and DDR2-800 memory. They are rated for embedded use. The series has an integrated graphics processor built directly into the CPU to help improve performance. The models are targeted at nettops and low-end desktops. They do not support SpeedStep.

The Atom D510 dual-core processor runs at 1.66GHz, with 1MB of L2 cache and a TDP rating of 13W.^[29]The single-core Atom D410 runs at 1.66GHz, with 512KB of L2 cache and a TDP rating of 10W.^[30]

Tunnel Creek microprocessor[edit]

Tunnel Creek is an embedded Atom processor used in the Queens Bay platform with theTopcliffPCH.

Lincroft microprocessor[edit]

The Lincroft (Z6xx) with theWhitney PointPCH is included in theOak Trailtablet platform. Oak Trail is an Intel Atom platform based onMoorestown. Both platforms include a Lincroft microprocessor, but use two distinct input/output Platform Controller Hubs (I/O-PCH), codenamedLangwelland Whitney Point respectively. Oak Trail was presented on 11 April 2011 and was to be released in May 2011.^{[dated info][31]}The Z670 processor, part of the Oak Trail platform, delivers improved video playback, faster Internet browsing and longer battery life, "without sacrificing performance" according to Intel. Oak Trail includes support for 1080p video decoding as well as HDMI. The platform also has improved power efficiency and allows applications to run on various operating systems, including Android, MeeGo and Windows.

Stellarton microprocessor[edit]

Third generation cores[edit]

The 32nm shrink of Bonnell is called Saltwell.

Cedarview microprocessor[edit]

Intel released their third-generation Cedar Trail platform (consisting of a range of Cedarview processors^[32]and the NM10 southbridge chip) based on 32nm process technology in the fourth quarter of 2011.^[31]Intel stated that improvements in graphics capabilities, including support for 1080p video, additional display options including HDMI and DisplayPort, and enhancements in power consumption are to enable fanless designs with longer battery life.

The Cedar Trail platform includes two new CPUs, 32nm-based N2800 (1.86GHz) and N2600 (1.6GHz), which replace the previous generation Pineview N4xx and N5xx processors. The CPUs also feature an integrated GPU that supports DirectX 9.

In addition to the netbook platform, two new Cedarview CPUs for nettops, D2700 and D3200, were released on 25 September 2011.^[33]

In early March 2012 the N2800-based Intel DN2800MT motherboard^[34]started to become available. Due to the use of a netbook processor, this Mini-ITX motherboard can reach idle power consumption as low as 7.1W.^[35]
