The Big Processor Guide - AMD Cores

Advanced Micro Devices, Inc., has historically been a small but notable figure in the microprocessor market. While never matching the enormous size of long-time rival (and one-time partner) Intel, they have firmly established themselves as the second biggest player in the marketplace. In the days of the 486, they were noted for producing chips able to clock to higher speeds than those made by Intel, who originated the architecture. In more modern times they have established themselves as a leader (at least for now) in high performance, low power consumption products, and have leveraged innovations such as HyperTransport to prove that the little guy can score technological wins.

While computer processors are their most high-profile business, a substantial portion of AMD's revenues have historically come from flash memory production (since spun off as Spansion, of which they own a good portion). They are also a player in the embedded device processor market now. And July 24, 2006, they announced they would be merging with ATI, thus putting them in the chipset and video card markets.

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."HTT" indicates the processor uses HyperTransport.

Phenom II

A better, faster Phenom. Phenom II products are in the Shanghai family, Barcelona's die-shrunk successor.

Deneb: The desktop version of Shanghai, Deneb is on a smaller process than its predecessors and includes other improvements. The result is higher performance and lower power usage, both of which earlier Phenom products needed. The 9xx series have 6 MB of L3 cache (shared between all cores), while the 8xx series have only 4 MB.

Phenom

The next generation, Phenom brings the new K10 microarchitecture to the desktop.

Toliman: Agena with one of the four cores disabled. All of the L3 cache is present. Because L2 cache in the K10 design is kept separate for the individual cores, the L2 cache associated with the disabled core is also disabled, so the total amount of L2 cache is reduced. Ditto for the L1 cache. Like Agena, Toliman has 2 MB of L3 cache, shared between all cores.

Agena: The first generation product, with 128 KB of L1 cache per core and a shared 2 MB L3 cache. Suffered a severe sales setback due to a TLB erratum related to a race condition. Adds support for SSE4a, which is not the same as Intel's SSE4.1.

Athlon X2

Exactly like the Athlon 64 X2, but with a shorter name. No, really.

Kuma: Some time after Brisbane, AMD released Kuma, the first K10-based product to carry the Athlon name. Kuma is a "discount" version of the K10-based Phenom X4 Agena; where Agena has 4 cores, Kuma has 2. But like the Phenom X3 Toliman, it's actually the same chip, just with 2 (presumably defective) cores disabled. 2 MB shared L3 cache. Launched the Athlon X2 7000 series.

Athlon 64 X2

The Athlon 64 X2 is AMD's first dual core desktop processor. It was originally aimed at the enthusiast market, but (as such things do) has gradually moved toward the mainstream. These chips essentially combine two Athlon 64 cores into a single device, with some links to allow communication between the two cores. While having two cores does not mean double the performance, there are applications where it can make a substantial difference.

Brisbane: A die shrink of Windsor (now exclusively with 512 KB of L2 cache per core). As is often the case for die shrinks, Brisbane's most apparent advantage is that it produces less heat. Its reduced size also lets AMD put more dice on one wafer, which means reduced production costs. AMD hopes to eek out slightly higher clock speeds, but time will tell on that point. Brisbane was initially troubled by yield issues (probably due to AMD's fairly evolutionary manufacturing process) and by increased L2 cache latency (to provide the option of increased L2 cache sizes later on).

Venice: Boasting an improved memory controller, and using less power than Clawhammer and Newcastle, Venice is truly a force to be reckoned with. Venice is a Socket 939-only chip. The first Athlon 64 X2 (dual-core) chips, Toledo and Manchester, are based on Venice.

Winchester: AMD's first 90 nm processors, Winchester was also the first Socket 939-only chip. With dramatically reduced power use and an improved memory controller, Winchester was a promising but short-lived step forward. It was quickly phased out in favor of Venice. Winchester brought SSE3 instructions to the line as well.

Clawhammer: the consumer version of the Opteron processors, and the world's first desktop 64-bit processors, Clawhammer chips were the first available for Socket 754, and were intended to be the successor to the Athlon XP. The original Clawhammers had 1 MB of L2 cache; later chips would be sold with only 512 KB, allegedly as a way of coping with manufacturing defects.

Athlon XP

In its day, the Athlon XP was respected by the technical community, adored by the value-conscious, and revered by overclockers. With an initially slow start, the Athlon XP eventually came roaring forward to flex its muscle. The XP series were the first to bear "PR Rating" designations.

Thorton: Something of a rarity, Thortons are basically Bartons with half their L2 cache disabled and their bus speed reduced, giving them specs identical to Thoroughbred B units. A clever use of Bartons with partially-defective L2 cache.

Manufacturer Core Series Socket Cores L2 Cache/Core FSB Process Size Top Speed
AMD Thorton Athlon XP A 1 256 KB 133 MHz x2 130 nm 2.2 (3100+)

Barton: The last gasp of Socket A, allowing it to go out with a bang and not a whimper. The Barton was a modified Thoroughbred B with more cache and the capability to use higher Front Side Bus speeds. It was given higher performance ratings relative to its clock speed than its predecessors, partly because of its greater cache. Virtually all Barton chips are actually the same chip, set to operate at a different speeds- thus making it a very overclocker-friendly processor.

AMD Barton Athlon XP A 1 512 KB 200 MHz x2 130 nm 2.2 GHz (3200+)

Thoroughbred B: The "B" chip represented a shift: in order to increase scalability (the ability to make faster versions of the chip), an extra layer (the ninth) was added to the core. This was rather like dealing with heavy city congestion by building subways, or skywalks. All previous Athlon XP cores were declared obsolete at its release, and all Palomino or Thoroughbred A processors were gradually displaced by Thoroughbred B versions of themselves. Some Thoroughbred B chips also supported a higher FSB.

Thoroughbred A: The "A" was added later to this successor to the Palomino, to separate it from the "B" revision. The Thoroughbred was a significantly more able processor than the Palomino, and cooler as well. This was in part due to a smaller process size.

Palomino: The first big upgrade to the Thunderbird Athlon and the initiator of QuantiSpeed ratings, this processor offered much greater potential speed at the cost of increased heat. The Palomino produced a large amount of heat compared to its contemporaries, and gave the AMD line its current reputation of running warmer. Could not be unlocked in the same way as Thunderbird Athlons, though it was still possible.

Athlon

In many ways, these were the chips that put AMD in a petition to really compete with Intel. Comparatively faster and cheaper, the Athlons firmly established AMD's foothold in the enthusiast market.

Thunderbird: The grand-daddy of the Socket A chips. It set the standards for the future generations, especially as regards its price advantage over Intel's offerings. First AMD processor with locked multipliers, though this could be undone with a common pencil.

Argon: AKA K7. The first Athlon "Classic", Argon represented a substantial improvement over previous K6-based designs. With an improved Floating-Point Unit and more L1 and L2 cache, it helped greatly expand AMD's market.

K6-III

In essence the K6-III is a K6-2 with on-die L2 cache.

Sharptooth: AKA Model 9. Sharptooth added its own on-die L2 cache, essentially treating motherboard-mounted cache as L3 cache rather than L2 cache. While expensive to produce (its transistor count nearly matched the Athlon that succeeded it, and was far greater than the K6-II), it proved to be quite profitable. A solid performer brought to market while Intel was struggling with manufacturing issues, Sharptooth became popular even among traditionally Intel-only vendors.

K6-2

At its base, the K6-2 was the K6 with the addition of AMD's 3DNow! instruction set. The K6-2 struck a major blow against Intel by performing well and being very cheap.

K6

Built on recently-acquired NexGen's Nx86 chip, retooled for Socket 7, the K6 was AMD's bid to put itself back in competitive standing with Intel. Performance was comparable to the Pentium Pro. The K6 launched shortly before the Pentium II, but ultimately was similar in performance. For this reason P-ratings were dropped for this series. The K6 did nonetheless have the advantage of being cheaper, and fitting in the Socket 7 used by Intel's desktop offerings. The K6 added MMX support.

Little Foot: AKA Model 7. Little Foot brought the K6 to Super Socket 7, allowing increased Front Side Bus speeds (and AGP). It was also a die shrink of Model 6.

K5

The K5 was AMD's attempt to compete with Intel's Pentium. And it was a dismal failure. Launched over a year late, it sold poorly. In addition to its other woes, it is noted to have produced quite a bit of heat for its time. K5 was an ambitious design, and like the Pentium Pro it contained a RISC core that translated x86 instructions into its internal "micro-ops" before execution. Confusingly, the K5 was refered to as the 5k86 until the release of the core codenamed 5k86... at which time it was refered to as the K5. The K5 was given P-ratings.

5k86: AKA Model 1. It should be noted that the PR200 is quite rare (and never entered regular distribution), and the fastest generally-available chip was the 116 MHz PR133.

Am5x86

A stopgap measure, AMD produced the Am5x86 while it awaited completion of the K5.

Am5x86: A very popular and very broadly compatible upgrade path for 486 owners. While unable to compete with the Pentium at a matching clock speed, the advantages over the 486 were substantial. Only one speed was manufactured in quantity, although a 150 MHz version reportedly exists.

Something of an oddity: the first Athlon X2 Black Edition came after Phenom Black Edition products were already on the market, and after the Athlon X2 series was no longer AMD's flagship. Still, these were much like other Black Edition products: unlocked multiplier, slightly higher clock speed.

The major break from tradition is that they are sold at a much more modest upcharge; where a new Athlon 64 FX or Pentium 4 Extreme Edition could have cost $1,000 in its day, these have typically been at a more achievable $250 or so.

Targeted at the enthusiast market, the Athlon 64 FX series is meant to represent the absolute best of AMD's desktop line- the state of the art. This sometimes means new technologies reach the FX series first, while in other cases it means simple amenities like unlocked multipliers and tighter testing tolerances. Initially offered only on the costly Socket 940 platform, the FX series eventually found its way to the more mainstream Socket 939.

Duron

AMD's first "value" line, analogous to Intel's Celeron, the Duron was a cheap but surprisingly hardy chip.

Applebred: The last gasp of Duron, with a bump to the Front Side Bus. Despite modest performance (and modest clock speeds), able to best the entire range of regular Celerons. The Applebred was a down-tuned Athlon XP Thoroughbred (A or B) with reduced cache. In some cases this cache was defective; in others, it could actually be re-enabled.

Laptop

Mainstream

Turion X2 Ultra

A new version of Turion introduced with AMD's Puma platform, the Turion X2 Ultra is meant to offer both better performance and lower power usage.

Griffin: A smaller process and more L2 cache are the most obvious changes from older products, but Griffin has more subtle differences as well. It moves from a single power plane for the entire chip to 3 (one for each of the two cores, and one for the integrated memory controller and everything else), allowing the chip to vary the voltage supplied to its different components. This means, most critically, that cores that are not very busy can be fed a lower voltage and thus consume less power. Griffin also moves to HyperTransport 3.0, which providesd more bandwidth but also the ability to change the link's "width" (from 16 lanes to 8) to save power. It is not yet clear if all versions will have 1 MB of L2 cache per core, or if some might have half that.

Turion 64

Strictly speaking, Turion is a "platform" or "package" of the same breed as Intel's Centrino brand. However, the requirements are so loose that essentially any laptop with the right processor meets them- and so in practice, the name Turion 64 is applied to the chips themselves.

Lancaster: At long last, a truly mobile chip from AMD. Based on the Winchester/Venice/San Diego cores, Lancaster produces dramatically less heat than its predecessors.

Value

Turion Neo

What makes it different from the Athlon Neo? We don't know, and AMD isn't telling. Our best guess is that there are additional platform requirements.

Conesus: Seemingly identical to the Athlon Neo Conesus. It has been suggested that the Athlon Neo X2 Conesus parts have less L2 cache (256 KB/core, for a total of 512 KB), but AMD's specs indicate otherwise.

Athlon Neo

Often compared to Intel's Atom, but probably more directly comparable to Intel's Consumer Ultra-Low Voltage (CULV) parts, the Athlon Neo is a low-power derivative of the K8 micro-architecture. AMD is pitching it for "ultrathin"/"thin and light" laptops to slot in around $700, above "netbooks" but below expensive laptops.

Conesus: Part of the Congo platform. Twice the cores of Huron. Some media outlets have suggested this to be a 45 nm part, but AMD's specifications indicate 65 nm. Possibly derived from Griffin, but certainly a K8 part.

Server

Opteron

The Opteron line was AMD's bid to take over a substantial portion of the server market. It enjoyed much greater success than the Athlon MP line before it, in part due to its excellent thermal characteristics. After appearing on the more consumer-oriented Socket 939, Opterons enjoyed a period of considerable popularity among overclockers. The more rigorous testing (and for a time surprisingly low prices) of these processors as compared to Athlon 64 and X2 alternatives proved to be very appealing.

Magny-Cours: Istanbul times two. Essentially two Istanbul dies on the same package, with relatively minor changes to the dies themselves. Introduced Direct Connect 2.0 to ensure that all dies are within one 'hop' of each other for the purpose of memory access. Added support for I/O virtualization. Up to 19.5 MB of total cache: 64 KB each of data and instruction L1 cache for each core, 512 KB of L2 for each core, and 12 MB of shared L3 (although 2 MB of the L3 is used for HT Assist). Note that the 8-core version is still made with dies that have 6 cores each, but 2 cores per die are disabled. Note the reduction in both 'core' and 'uncore' clock speeds vs. Istanbul, which helps keep thermal needs reasonable.

Shanghai: Principally a die shrink of Barcelona, Shanghai also added more L3 cache (6 MB shared between the cores, versus 2 MB), support for faster memory, and tricks like Smart Fetch. Shanghai is, in short, what Barcelona was supposed to be. It is not a dramatic architectural change, but rather a refinement.

Barcelona: The first K10 product to market, Barcelona finally retired the K8 series of Opterons. Dual- and quad-processor-capable versions were available at launch, with single-processor parts to follow. The launch was unfortunately marred by a TLB erratum that caused AMD to scramble to do damage control.

Santa Rosa: Ushering in the era of "Revision F" Opterons, Santa Rosa makes the jump to Socket F. The switch came shortly after desktop chips moved to Socket AM2. Santa Rosa is available with support for 2 or 8 chips in a system (or less, of course). Santa Rosa Opterons are members of the Opteron 22xx (up to 2 processors per system) or 82xx (up to 8 processors per system) family.
