The Big Processor Guide - Intel Cores

Intel is and has been the 800 lb. gorilla of computer processors. They've been in the microprocessor market since it was born (and they helped deliver it). Intel made the computer processor what it is today: the 8086 essentially established the architecture that would define every x86 processor for decades.

In addition to computer processors, Intel makes a broad variety of other chips. They are in fact the single largest manufacturer of chips on Earth.

Note: All Front Side Bus speeds are listed at the frequency of the clock that drives them; double-pumping is indicated by a "x2" and quad-pumping by an "x4". This page identifies sockets that support those features.

Core i3

For when the Core i5 is still too expensive, but not by much.

Clarkdale: Like the Core i5 Clarkdale, but with a slightly slower uncore clock speed and no Turbo Boost, AES-NI, VT-d, or TXT.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Uncore clock	Top Speed
Intel	Clarkdale	Core i3	LGA1156	2	256 KB	2.5 GT/s DMI	32 nm	2.13 GHz	3.06 GHz (540)

Core i5

The cheaper (but still not cheap) counterpart to Core i7.

Clarkdale: The first Westmere part on the market, Clarkdale is notable mainly because it has an on-package (but not yet on-die) graphics processor. The integrated memory controller was relocated from the processor die to the die housing the GPU, making that die effectively a full northbridge. The two dice communicate through a QPI link of unspecified speed. We have chosen to describe this as a 32 nm part, although the die with the GPU is actually 45 nm. Unlike Core i5 Lynnfield, Core i5 Clarkdale supports Hyper-Threading. 4 MB of L3 cache shared by the cores. For whatever reason, model numbers ending in 1 lack VT-d and TXT but get a faster clock for the GPU. All models support AES-New Instructions and SSE4.2.

Intel	Clarkdale	Core i5	LGA1156	2	256 KB	2.5 GT/s DMI	32 nm	2.4 GHz	3.46 GHz (670)

Lynnfield: Basically the same as the Core i7 Lynnfield, but with Hyper-Threading disabled.

Intel	Lynnfield	Core i5	LGA1156	4	256 KB	2.5 GT/s DMI	45 nm	2.13 GHz	2.66 GHz (750)

Core i7

The "next generation" replacing the Core 2 family, the Core i7 has one of the more nonsensical names to ever emerge out of Intel's marketing department.

Lynnfield: The more economical follow-up to Bloomfield, now with an on-die PCI-Express controller (providing 16 lanes perfect for connecting to a graphics processor... like Larrabee). Some things were cut: the ridiculously fast QPI link is gone, in favor of a slower DMI link to the chipset (since this link no longer needs to service the graphics processor, and there are no plans for a multiprocessor Lynnfield, this is adequate). The on-die memory controller has been trimmed down from 3 channels to 2. Still has 8 MB of L3 cache for the cores to share. Core i7 Lynnfield supports Hyper-Threading: Core i5 Lynnfield does not.

Intel	Lynnfield	Core i7	LGA1156	4	256 KB	2.5 GT/s DMI	45 nm	2.4 GHz	2.93 GHz (870)

Bloomfield: The first Core i7 product and the first product based on the Nehalem microarchitecture, Bloomfield makes up both the mainstream Core i7 and the Core i7 Extreme. 8 MB of L3 cache is shared between the cores. On the LGA1366 socket, Bloomfield supports QPI and sports a memory controller that runs at a lower frequency than the core clock (what has been dubbed the "uncore clock").

Intel	Bloomfield	Core i7	LGA1366	4	256 KB	4.8 GT/s QPI	45 nm	2.13 GHz	3.2 GHz (960)

Core 2 Quad

As the name implies, the Core 2 Quad is a bigger brother to the Core 2 Duo, technologically similar but with 4 cores instead of 2.

Yorkfield: Penryn-family quad-core part, in effect a die shrink of Kentsfield. Still a "dual die" product. Support for SSE4.1.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Yorkfield	Core 2 Quad	T	4	3 MB	333 MHz x4	45 nm	3.0 GHz (Q9650)

Intel	Yorkfield	Core 2 Quad	T	4	1 MB	333 MHz x4	45 nm	2.66 GHz (Q8400)

Kentsfield: Two Conroe cores dropped into a single package. Like the Pentium D Presler, this is a "dual die" product.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Kentsfield	Core 2 Quad	T	4	2 MB	266 MHz x4	65 nm	2.67 GHz (Q6700)

Core 2 Duo

The return of the king. Core 2 Duo is a step back toward the Pentium III- lower power consumption, better performance.

Wolfdale: A 45 nm die shrink of Conroe, or a desktop adaptation of the laptop Core 2 Duo Penryn, however you prefer to think about it. Like Penryn, it adds SSE4.1 instructions. L2 cache is still shared between the cores, L1 cache is still not.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Wolfdale	Core 2 Duo	T	2	3 MB	333 MHz x4	45 nm	3.16 GHz (E8500)

Conroe: The big daddy, Conroe benefits from the strengths of the new Core microarchitecture as well as an increased Front Side Bus speed.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Conroe	Core 2 Duo	T	2	1 MB	266 MHz x4	65 nm	2.13 GHz (E6400)

Intel	Conroe	Core 2 Duo	T	2	2 MB	333 MHz x4	65 nm	3.0 GHz (E6850)

Allendale: A design very similar to Conroe, but natively having less L2 cache. The E6300 and E6400 (which have 2 MB of L2 cache) were initally assumed to be Allendale products, but were in fact Conroe chips with half their L2 cache disabled. Confusingly, later E6300 and E6400 chips actually were Allendale products.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Allendale	Core 2 Duo	T	2	1 MB	200 MHz x4	65 nm	2.2 GHz (E4500)
Intel	Allendale	Core 2 Duo	T	2	1 MB	266 MHz x4	65 nm	2.13 GHz (E6400)

Pentium D

In essence, the Pentium D chips are simply two Pentium 4s in a single package. The idea is to provide the performance benefits of having two processors, but at a lower cost and with less bulk. The reality is somewhat less impressive.

Presler: Two Cedar Mill cores on one chip. Some have refered to this as "double core" rather than "dual core" because the cores are actually separately-manufactured Cedar Mills that are then placed into the same package. Supports EM64T, the No Execute bit, and Vanderpool. Originally slated to support Enhanced Speedstep, but stability concerns forced Intel to disable this feature on the initial run. Does not support Hyper-Threading.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Presler	Pentium D	T	2	2 MB	200 MHz x4	65 nm	3.4 GHz (950)

Smithfield: Essentially two Prescott cores on one chip. Supports EM64T and the No Execute bit; does not support Hyper-Threading or Vanderpool.

Intel	Smithfield	Pentium D	T	2	1 MB	200 MHz x4	90 nm	3.2 GHz (840)

Pentium 4

The long-running, long-suffering leading-edge consumer product from Intel, the Pentium 4 has had more faces than Joan Rivers. Some well-loved, some reviled, they are nothing if not diverse.

Cedar Mill: Die shrink of the Prescott 2M. Supports everything the Prescott 2M 672 does, including SSE1, 2, and 3, EM64T, No Execute, Hyper-Threading, and Vanderpool.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Cedar Mill	Pentium 4	T	1	2 MB	200 MHz x4	65 nm	3.6 GHz (661)

Prescott 2M: A revised Prescott bearing 2 MB of cache (hence the change in the name). Like some previous Prescotts, all Prescott 2M chips support EM64T, the No Execute bit, and Hyper-Threading. The 662 and 672 (only) support Vanderpool virtualization. All others are named 6x0.

Intel	Prescott 2M	Pentium 4	T	1	2 MB	200 MHz x4	90 nm	3.8 GHz (672)

Prescott "E": The Prescott was the result of Intel's long and troubled transition to a 90 nm manufacturing process. The Prescott chips were criticized immediately for performing worse than Northwood C chips at the same speeds and for their very high heat output. Intel promised that the chips would show their true colors as they scaled up in speed (and indeed, tests showed they did quite better at speeds of 3.4 GHz and above). All Prescotts support SSE3.

Intel	Prescott	Pentium 4	478	1	1 MB	200 MHz x4	90 nm	3.4 GHz
Intel	Prescott	Pentium 4	478	1	1 MB	133 MHz x4	90 nm	2.8 GHz

Intel	Prescott	Pentium 4	T	1	1 MB	133 MHz x4	90 nm	3.06 GHz (519)

Northwood "C": The golden age of the Pentium 4. This core substantially outperformed previous Pentium 4s, due mainly to the substantial impact of Front Side Bus speed on NetBurst chips. The real accomplishment of the Northwood C, however, was its much-praised overclocking potential. Boasting the most impressive and consistent overclocking performance since the early-model Celerons, it would gain a reputation (particularly, the 2.4 GHz chip) as the undisputed king of overclocking. Only when AMD's Athlon XP Barton core (and subsequent Mobile variants) appeared would that crown show even a hint of tarnish.

Intel	Northwood C	Pentium 4	478	1	512 KB	200 MHz x4	130 nm	3.4 GHz

Northwood "B": The first chips to have enabled Hyper-Threading, though it was exclusive to the 3.06 GHz version. Increased Front Side Bus speed would help give these chips a leg up over their predecessors, but they were otherwise rather unremarkable.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Northwood B	Pentium 4	478	1	512 KB	133 MHz x4	130 nm	3.06 GHz

Northwood "A": The (much-requested) replacement for Willamette, this core ushered in the beginning of an era when Pentium 4 performance really could impress. With architectural changes, more cache, lower heat output, and resulting better scalability, the Northwood series is hands-down superior to Willamette. The "A" was affixed to model numbers to separate the Northwood from the Willamette; future revisions of the Pentium 4 would be distinguished by different letters.

Intel	Northwood A	Pentium 4	478	1	512 KB	100 MHz x4	130 nm	2.6 GHz

Willamette: The bastard child. Willamette was mocked at its introduction because at the same clock speeds it would substantially under-perform older Pentium IIIs. Some of this stumbling was aleviated when Socket 423 died a quick death, but Willamette continued to be dogged by performance issues until it was finally phased out. Willamette added SSE2 extensions.

Pentium III

Considered by some to be the peak of Intel's processor prowess, the Pentium III continues to be a sought-after chip for all manner of moderate-duty tasks. In later years the architecture would be revived for the Pentium M, and its spiritual successor would appear in the form of Merom. The Pentium III was in many ways just an updated Pentium II, with changes such as a new card packaging that allowed better heatsink contact.

Tualatin: Tualatin is regarded by many as little more than a die shrink. It was eventually made available with increased L2 cache for improved performance.

Manufacturer	Core	Series	Socket	Cores	L2 Cache/Core	FSB	Process Size	Top Speed
Intel	Tualatin	Pentium III	370	1	256 KB	133 MHz	130 nm	1.4 GHz
Intel	Tualatin	Pentium III-S	370	1	512 KB	133 MHz	130 nm	1.4 GHz

Coppermine: Coppermine's two greatest changes were a die shrink and substantially speeding up the L2 cache. Where on the Katmai core the L2 cache had operated at half the frequency of the processor, on the Coppermine it operated at the same frequency. The cache was also brought onto the die itself to facilitate the change (this, in turn, was facilitated by the die shrink).

Katmai: In truth only slightly different from the Pentium II, Katmai added SSE instructions and gained an improved memory controller for its L1 cache.

Pentium II Overdrive

A Pentium II adapted for use in Socket 8 motherboard, the Pentium II Overdrive was meant to provide an upgrade path to Pentium Pro owners.

P6T: Pentium II Deschutes, but on Socket 8.

Pentium II

Based on the Pentium Pro P6, the Pentium II was Intel's first slot-and-cartridge type processor. This was a tradeoff decision that allowed engineers to give the processor locally available L2 cache on the same PCB as the processor, at less cost than integrating it into the die.

Deschutes: On a smaller process and available with a faster Front Side Bus, the Deschutes core was a relatively simple but substantial improvement over Klamath. Heat issues were greatly reduced by the die shrink.

Klamath: The first Pentium II dealt with substantial heat issues, and suffered under the limitations of its Front Side Bus speed.

Pentium MMX

The Pentium chip, but with the addition of the MMX instruction set. Double the L1 cache.

P55C: Modified Pentium P54C.

Pentium Overdrive

Ostensibly meant to provide an upgrade path for 486 owners wanting a taste of Pentium power, the Pentium Overdrive is largely a footnote in history. Performance issues and poor availability essentially mooted the product.

P54CTB: Essentially the Pentium MMX P55C, but adapted to Socket 5.

Intel	P54CTB	Pentium Overdrive	5	1	0 KB	66 MHz	350 nm	200 MHz

P54CT: Derived from the P54CS. Suffered from many of the same limitations as P5T, but had to also package in its own voltage regulator. 486 motherboards delivered a 5 V supply, and it needed 3.3 V.

Intel	P54CT	Pentium Overdrive	5	1	0 KB	66 MHz	350 nm	166 MHz

P5T: Derived from the Pentium P5. Adapting it to work on (some) 486 motherboards was difficult; it needed more L1 cache to boost performance, but still suffered considerably.

Pentium

Intel's take on a "586", the Pentium was a move to create their own proprietary chips, to allow them to differentiate their brand. Where in the days of the 486 several companies made chips that bore the marker "486", only Intel could produce a Pentium. One notable benefit was that they could create separate server/workstation lines to segment the market. The Pentium brand was the central focus of an enormous and very successful marketing push by Intel, and became one of rather few computer-industry brands to truly become a household name.

P54CQS/P54CS: Die shrink of P54C.

Intel	P54CS	Pentium	5	1	0 KB	66 MHz	350 nm	200 MHz

P54C: The P54C was architecturally the same as the P5, but it ran on a lower voltage (3.3 V versus 5 V), was built on a smaller process, and was a pure CMOS device while the P5 contained some bipolar logic. The net effect was that it produced much less heat.

P5: The original Pentium, what some would have liked to see called the 80586 instead. The P5 offered substantial performance gains over the 486, and Intel chose to drop its price below the 486. However, it produced quite a bit of heat for a chip of its time. And in a great embarassment to Intel, some models contained an error that would in rare cases cause it make mistakes in floating point math- the FDIV bug. Intel was eventually forced to recall them to quell the public relations problem.

Core i7 Extreme

Another iteration of the same concept, the Core i7 Extreme is very much like the regular Core i7, but with more power.

Gulftown: If you liked its Bloomfield predecessor but wanted more, you got it. 50% more cores (6) and 50% more L3 cache (12 MB), plus all the good stuff that comes with being a Westmere part (a die shrink, AES-NI).

Core 2 Extreme

Bringing the Extreme Edition concept into the Core era.

Harpertown: The Xeon Harpertown, repurposed as an enthusiast part. A lot like Yorkfield, but with an even faster Front Side Bus. Intended for use with Intel's SkullTrail platform (which is a dual-processor setup), this Core 2 Extreme uses the socket normally reserved for Xeons rather than a typical desktop socket.

Pentium

Apparently not satisfied with confusing the world with the "Pentium Dual-Core", Intel decided to reuse the Pentium name with no modifiers at all, in a move sure to confound people for years.

Clarkdale: Much like the Core i3 and i5 CLarkdale, but cut down just a bit more. No Hyper-Threading, less L3 cache (3 MB instead of 4 MB), slower uncore clock, an on-die GPU down-tuned to 533 MHz, and all of the restrictions of Core i3 Clarkdale.

Wolfdale: Derived from the Core 2 Wolfdale, but with a slower FSB and reduced L2 cache. Just in case you thought there was any sanity in Intel's marketing department, one of the first products in this series was the Pentium E6300, which might easily be confused with the not-that-much-older Core 2 Duo E6300.

Pentium Dual-Core

Quietly introduced not long after the Pentium brand was supposedly retired, the Pentium Dual-Core is essentially a cut-down version of either the Core Duo or Core 2 Duo.

Allendale: Just like the Core 2 Duo Allendale, but with half the L2 cache. Confusingly, often found in laptops despite being identified as a desktop product by Intel.

Celeron 400 series

Listed here because they were introduced after the Celeron D products, these are essentially cut-down Core 2 Duos.

Millville: A trimmed down, single-core version of Conroe. Often called Conroe-L. It is unclear which is the actual codename used by Intel. Please note that several Celeron M products use very similar model numbers.

Celeron D

The Celeron D ushered in an impressive recovery for the Celeron series. For years, the Celerons had lagged behind AMD's Durons (which ran at lower clock speeds, used less power, and were cheaper) in performance. And also for years, the Celerons had been designed completely independently of the flagship Pentium series. The Celeron D marked a return to the good old days of the Celeron, when it was basically a down-tuned Pentium.

Celeron

The Celerons have taken many forms. Many Pentium cores have been recast as Celerons, usually by reducing their cache and sometimes also their Front Side Bus speeds. Some Celeron cores were designed separately (or at least, mostly separately). After the end of the Pentium III-based Celerons, there was a long dark age that ended only with the introduction of the Celeron D.

Northwood "A": Based on the Pentium 4 Northwood A, but with half the cache- thus it is often called Northwood-128.

Willamette: Similar to the Pentium 4 Willamette, but with half the L2 cache. Consequently, often called Willamette-128. Sometimes refered to as the Celeron 4 to distinguish it from previous designs.

Tualatin: As was the case for the Celeron Coppermine, the Celeron Tualatin was for all intents and purposes the same as its Pentium III big brother, with less L2 cache than the Pentium III-S version and a slower Front Side Bus. Reportedly, its L2 cache controller had slightly higher latency. The nickname "Tualeron" was coined as a portmanteau of Tualatin and Celeron.

Coppermine: Essentially the same as the Pentium III core of the same name, but with reduced L2 cache and a limited Front Side Bus. Often refered to as "Coppermine-128" in honor of its lesser L2 cache, and sometimes called "Celeron II".

Mendocino: Based on the Pentium II, Mendocino sought to rectify the poor performance of Covington by adding L2 cache. Mendocino had on-die L2 cache before the Pentium line did (contemporary Pentium IIs had off-die cache on their PCB). It was in this period that benchmarks began to reveal Celerons could actually outperform their more expensive Pentium brothers; Intel would soon take measures to put a stop to that. Some Mendocino models had names ending in "A" to separate them from Covington chips, and as a result some people continue to refer to them as the "Celeron A" series.

Bringing the oomph of the Core i7 desktop products to laptops.

Arrandale: Based on the desktop Core i5 Clarkdale. Model numbers end in a 1- or 2-letter code that indicates TDP and speed of the GPU. Model numbers ending in E support ECC memory. Model numbers containing a U only support DDR3-800 memory, not DDR3-1066, and have a slower clock for the GPU. 4 MB of L3 cache. The uncore clock is our best guess based on the desktop part.

Notice that Intel finally did the smart thing and put an 'M' on the end of model numbers to distinguish them from desktop parts. Hyper-Threading is supported. Intel has not disclosed uncore clock speeds at this time, but our best guess is 2.13 GHz.

Pentium M

More performance at a lower clock speed, using less power, made the Pentium M series the most popular laptop processor at the dance. The Pentium M dramatically improved laptop battery life and firmly cemented Intel's dominance of the notebook market. The Pentium M also made use of deeper "sleep" states, and more importantly used them more effectively, contributing to its impressive power reduction.

Dothan: A better, faster Banias. With more cache, a smaller process, and lower power use, Dothan proved to be a nice step up from the already impressive Banias. Improved power management including deeper sleep states and active processor speed throttling.

Banias: Based on the architecture of the Pentium III, Banias came from Intel's design facility in Israel. It introduced a concept known as "Micro-Ops Fusion", whereby the micro-operations to be executed by the processor could be "fused" (that is, certain combinations would be combined into a single operation) before execution.

Celeron M

This series is very much like the Pentium M, but lacks SpeedStep. Celeron M chips are otherwise essentially copies of their Pentium M (later Core 2) brothers, but with half as much L2 cache.

Merom-L: A revision to the Celeron M Merom. This codename definitely is used by Intel. Intel notes a "minor die size decrease", which has been speculated to mean that it is actually manufactured with reduced L2 cache, rather than simply having some L2 cache disabled. It may also be the case that the size reduction is related to the "Merom Refresh" release.

Xeon MP

Xeon with support for more than two processors in one system.

Nehalem-EX: When you really, absolutely must have up to 256 Nehalem-based processors. Up to 24 MB of shared L3 cache. Hyper-Threading and Turbo Boost supported by most but not all models. Note that most parts are in the Xeon 7500 series, while a few are in the Xeon 6500 series; we suspect that the principle difference is that the 6500 series likely does not support systems with huge numbers of sockets.

Dunnington: The last major Xeon release before the next Nehalem microarchitecture, Dunnington is apparently built on the "more is better" philosophy. Dunnington packs as many as 3 Penryn-like processors (a total of 6 cores) into one chip. L2 cache is shared between pairs of cores (but not between the pairs), while up to 16 MB of L3 cache is shared between all cores. Testing by Anandtech has suggested that the L3 cache runs at half the core clock speed. As evidenced by die shots, Dunnington is a "true"/"native" 6-core design, not a multi-chip-module one. Dunnington is the first product out of Intel's Bangalore, India, design team. Please note that in our table below, we have appended a number to the Core name to indicate the amount of L3 cache.

Dual processor

Xeon DP

Xeon with support for up to two processors in one system. Older Xeons also supported DP use, but with the introduction of Pentium 4-based Xeons Intel began to differentiate between DP and MP.

Lynnfield: As with Bloomfield and others before it, this is the desktop Core i7 Lynnfield turned into a Xeon. Same feature set as Core i7 Lynnfield, except for the Xeon X3430 which, like the Core i5 Lynnfield, does not support Hyper-Threading. 8 MB of L3 cache.

Bloomfield: Continuing their tradition of turning mainstream parts into single-socket-only Xeons, Intel turned Bloomfield into the 3500 series of Xeons. And continuing our tradition of lumping such Xeons in with the dual-socket parts, we have listed them here. Essentially the same feature set as the desktop Bloomfield or, for that matter, Xeon Nehalem. 8 MB of L3 cache.

Westmere-EP: A die shrink of Nehalem or Gulftown brought to the server farm, however you prefer to think of it. More cores than Nehalem. Adds AES-NI, Turbo Boost, TXT, and the other goodies that come with Gulftown. 12 MB of shared L3. Parts with a W or X model number have faster QPI links than those with L or E model numbers In true Intel fashion, almost all (but not all) parts support Hyper-Threading and Turbo Boost; L5609 has neither, and is additionally cursed with an even slower QPI link.

Nehalem: As usual for Intel, server parts were the last to move to a new microarchitecture. This is perhaps a bit ironic in this case, where Nehalem was actually the "main" product from which desktop and mobile variants were derived, and was the microarchitecture's namesake. The naming system is a bit complicated; see our description on the naming page.

Xeon

Following in the footsteps of the Pentium Pro, the Xeon is marketed toward the server and workstation markets. Xeons have been produced based on the same architectures as much of the Pentium line.

Cascades: Another Pentium III Xeon, initially criticized for the fact that its low L2 cache made it indisitinguishable from ordinary Pentium IIIs of its day. Later versions increased the cache but also descreased the Front Side Bus, for a net performance improvement.

Pentium Pro

The "professional" version of the Pentium, the Pentium Pro was marketed to server and workstation markets with claims of improved performance in such tasks.

P6: Benefiting from valuable (but costly) built-in L2 cache, the P6 was powerful for its time but faced substantial yield problems. L2 cache added greatly to the transistor count of the chip, and therefore made it more expensive and more difficult to produce.

Embedded

Mainstream

Atom

Atom is Intel's attempt to move x86 into the embedded space, similar to AMD's Geode.

Pineview: Pineview is notable mainly for its integrated GPU (GMA 3150) and memory controller, which improved power use but not performance. Part of the Pinetrail platform. Intel describes two versions of Pineview: "Pineview-M", intended for netbooks; and "Pineview-D", intended for desktops; Pineview-M has a lower TDP (probably because Pineview-M gets Enhanced SpeedStep) and a less-capable memory controller. Model numbers starting with N are Pineview-M (why not M?), model numbers starting with D are Pineview-D. No support for Intel Virtualization. Model numbers of the form x5xx have 2 cores; model numbers of the form x4xx have 1 core. Unlike Atom 330, dual-core Pineview is a "true" dual-core part, with both cores on the same die. Intel describes the socket as FCBGA559 or FC-BGA8.

Intel	Pineview	Atom	FCBGA559	1	512 KB	DMI	45 nm	1.83 GHz (N470)

Silverthorne: Something of a throwback to the days of the original Pentium, Silverthorne is Intel's first in-order (versus out-of-order) design in years. It is the combination of the Bonnell core, L2 cache, and an external bus interface. It is otherwise designed to support the same ISA as Merom, including SSE instructions up to SSSE3 and Intel Virtualization Technology. All versions use a surface-mount BGA437 (also called uFCBGA8) package; no sockets.

Intel	Silverthorne	Atom	BGA437	1	512 KB	133 MHz x4	45 nm	1.6 GHz (230)

Diamondville: Diamondville is an even smaller, even lower power version of Silverthorne intended for what Intel calls "Mobile Internet Devices". While Silverthorne uses a standard GTL+ FSB, like most Intel processors, Diamondville uses a lower-power CMOS bus. This saves power, but makes Diamondville incompatible with any chipset except the Poulsbo chipset (UL11/US15), which was developed specifically for it. Diamondville does not support Intel's 64-bit extensions, but generally supports the same ISA as Silverthorne. All but the Z510 support Symmetric Multi-Threading (like the Pentium 4's Hyper-Threading). All versions use a surface-mount BGA package; no sockets. The initial and (when present) ending letter in the model number provide information on the package. The Z515 supports "Burst Mode" (similar to Turbo Boost), which allows it to increase its clock speed to 1.2 GHz for brief periods (the "regular" clock speed has not been specified yet), but not Hyper-Threading.
