Overview[edit]

The Xeon brand has been maintained over several generations of x86 and x86-64 processors. Older models added the Xeon moniker to the end of the name of their corresponding desktop processor, but more recent models used the name Xeon on its own. The Xeon CPUs generally have more cache than their desktop counterparts in addition to multiprocessing capabilities.

List of Intel Xeon microprocessors

P6-based Xeon[edit]

Pentium II Xeon[edit]

A 450 MHz Pentium II Xeon with a 512 kB L2 cache. The cartridge cover has been removed.

The first Xeon-branded processor was the Pentium II Xeon (code-named "Drake"). It was released in 1998, replacing thePentium Pro in Intel's server lineup. The Pentium II Xeon was a "Deschutes" Pentium II (and shared the same product code: 80523) with a full-speed 512 kB, 1 MB, or 2 MB L2 cache. The L2 cache was implemented with custom 512 kB SRAMs developed by Intel. The number of SRAMs depended on the amount of cache. A 512 kB configuration required one SRAM, a 1 MB configuration: two SRAMs, and a 2 MB configuration: four SRAMs on both sides of the PCB. Each SRAM was a 12.90 mm by 17.23 mm (222.21 mm²) die fabricated in a 0.35 µm four-layer metal CMOS process and packaged in a cavity-down wire-bonded land grid array (LGA).^[1]The additional cache required a larger module and thus the Pentium II Xeon used a larger slot, Slot 2. It was supported by the 440GX dual-processor workstation chipset and the 450NX quad- or octo-processor chipset.

Pentium III Xeon[edit]

In 1999, the Pentium II Xeon was replaced by the Pentium III Xeon. Reflecting the incremental changes from the Pentium II "Deschutes" core to the Pentium III "Katmai" core, the first Pentium III Xeon, named "Tanner", was just like its predecessor except for the addition of Streaming SIMD Extensions (SSE) and a few cache controller improvements. The product codes forTanner mirrored that of Katmai; 80525.

The second version, named "Cascades", was based on the Pentium III "Coppermine" core. The "Cascades" Xeon used a 133 MHz bus and relatively small 256 kB on-die L2 cache resulting in almost the same capabilities as the Slot 1 Coppermine processors, which were capable of dual-processor operation but not quad-processor operation.

To improve this situation, Intel released another version, officially also named "Cascades", but often referred to as "Cascades 2 MB". That came in two variants: with 1 MB or 2 MB of L2 cache. Its bus speed was fixed at 100 MHz, though in practice the cache was able to offset this. The product code forCascades mirrored that of Coppermine; 80526.

Netburst-based Xeon[edit]

Xeon (DP) & Xeon MP (32-bit)[edit]

Foster[edit]

List: List of Intel Xeon microprocessors#"Foster" (180 nm)

List: List of Intel Xeon microprocessors#"Foster MP" (180 nm)

In mid-2001, the Xeon brand was introduced ("Pentium" was dropped from the name). The initial variant that used the new NetBurst microarchitecture, "Foster", was slightly different from the desktop Pentium 4 ("Willamette"). It was a decent chip for workstations, but for server applications it was almost always outperformed by the older Cascades cores with a 2 MB L2 cache and AMD's Athlon MP. Combined with the need to use expensive Rambus Dynamic RAM, the Foster's sales were somewhat unimpressive.

At most two Foster processors could be accommodated in a symmetric multiprocessing (SMP) system built with a mainstream chipset, so a second version (Foster MP) was introduced with a 1 MB L3 cache and the Jackson Hyper-Threading capacity. This improved performance slightly, but not enough to lift it out of third place. It was also priced much higher than the dual-processor (DP) versions. The Foster shared the 80528 product code with Willamette.

Prestonia[edit]

List: List of Intel Xeon microprocessors#"Prestonia" (130 nm)

In 2002 Intel released a 130 nm version of Xeon branded CPU, codenamed "Prestonia". It supported Intel's new Hyper-Threading technology and had a 512 kB L2 cache. This was based on the "Northwood" Pentium 4 core. A new server chipset, E7500 (which allowed the use of dual-channel DDR SDRAM), was released to support this processor in servers, and soon the bus speed was boosted to 533 MT/s (accompanied by new chipsets: the E7501 for servers and the E7505 for workstations). The Prestonia performed much better than its predecessor and noticeably better than Athlon MP. The support of new features in the E75xx series also gave it a key advantage over the Pentium III Xeon and Athlon MP branded CPUs (both stuck with rather old chipsets), and it quickly became the top-selling server/workstation processor.

Subsequent to the Prestonia was the "Gallatin", which had an L2 cache of 1 MB or 2 MB. Its Xeon MP version also performed much better than the Foster MP, and was popular in servers. Later experience with the 130 nm process allowed Intel to create the Xeon MP branded Gallatin with 4 MB cache. The Xeon branded Prestonia and Gallatin were designated 80532, like Northwood.

Xeon (DP) & Xeon MP (64-bit)[edit]

Nocona and Irwindale[edit]

Main article: Pentium 4#Prescott

List: List of Intel Xeon microprocessors#"Nocona" (90 nm)

List: List of Intel Xeon microprocessors#"Irwindale" (90 nm)

Due to a lack of success with Intel's Itanium and Itanium 2 processors, AMD was able to introduce x86-64, a 64-bit extension to the x86 architecture. Intel followed suit by including Intel 64 (formerly EM64T; it is almost identical toAMD64) in the 90 nm version of the Pentium 4 ("Prescott"), and a Xeon version codenamed "Nocona" with 1 MB L2 cache was released in 2004. Released with it were the E7525 (workstation), E7520 and E7320 (both server) chipsets, which added support for PCI Express, DDR-II and Serial ATA. The Xeon was noticeably slower than AMD's Opteron, although it could be faster in situations where Hyper-Threading came into play.

A slightly updated core called "Irwindale" was released in early 2005, with 2 MB L2 cache and the ability to have its clock speed reduced during low processor demand. Although it was a bit more competitive than the Nocona had been, independent tests showed that AMD's Opteron still outperformed Irwindale. Both of these Prescott-derived Xeons have the product code 80546.

Cranford and Potomac[edit]

64-bit Xeon MPs were introduced in April 2005. The cheaper "Cranford" was an MP version of Nocona, while the more expensive "Potomac" was a Cranford with 8 MB of L3 cache. Like Nocona and Irwindale, they also have product code 80546.

The first dual-core CPU branded Xeon, codenamed Paxville DP, product code 80551, was released by Intel on 10 October 2005. Paxville DP had NetBurst microarchitecture, and was a dual-core equivalent of the single-core Irwindale (related to the Pentium D branded "Smithfield"") with 4 MB of L2 Cache (2 MB per core). The only Paxville DP model released ran at 2.8 GHz, featured an 800 MT/s front side bus, and was produced using a 90 nm process. ^{[check quotation syntax]}

On 23 May 2006, Intel released the dual-core CPU (Xeon branded 5000 series) codenamed Dempsey (product code 80555). Released as the Dual-Core Xeon 5000-series, Dempsey is a NetBurst microarchitecture processor produced using a 65 nm process, and is virtually identical to Intel's "Presler" Pentium Extreme Edition, except for the addition of SMP support, which lets Dempsey operate in dual-processor systems. Dempsey ranges between 2.50 GHz and 3.73 GHz (model numbers 5020–5080). Some models have a 667 MT/s FSB, and others have a 1066 MT/s FSB. Dempsey has 4 MB of L2 Cache (2 MB per core). A Medium Voltage model, at 3.2 GHz and 1066 MT/s FSB (model number 5063), has also been released. Dempsey also introduces a new interface for Xeon processors: LGA 771, also known as Socket J. Dempsey was the first Xeon core in a long time to be somewhat competitive with its Opteron-based counterparts, although it could not claim a decisive lead in any performance metric – that would have to wait for its successor, the Woodcrest.

List: List of Intel Xeon microprocessors#"Sossaman" (65 nm)

On 14 March 2006, Intel released a dual-core processor codenamed Sossaman and branded as Xeon LV (low-voltage). Subsequently an ULV (ultra-low-voltage) version was released. The Sossaman was a low-/ultra-low-power and double-processor capable CPU (like AMD Quad FX), based on the "Yonah" processor, for ultradense non-consumer environment (i.e. targeted at the blade-server and embedded markets), and was rated at a thermal design power (TDP) of 31 W (LV: 1.66 GHz, 2 GHz and 2.16 GHz) and 15 W (ULV: 1.66 GHz).^[4] As such, it supported most of the same features as earlier Xeons: Virtualization Technology, 667 MT/s front side bus, and dual-core processing, but did not support 64-bit operations, so could not run 64-bit server software, such as Microsoft Exchange Server 2007, and therefore was limited to 16 GB of memory. A planned successor, codenamed "Merom MP" was to be a drop-in upgrade to enable Sossaman-based servers to upgrade to 64-bit capability. However, this was abandoned in favour of low-voltage versions of the Woodcrest LV processor leaving the Sossaman at a dead-end with no upgrade path.

On 11 November 2007 Intel presented Yorkfield-based Xeons – called Harpertown (product code 80574) – to the public.[9] This family consists of dual die quad-core CPUs manufactured on a 45 nm process and featuring 1066 MHz, 1333 MHz, 1600 MHz front-side buses, with TDP rated from 40 W to 150 W depending on the model. These processors fit in the LGA 771package. All models feature Intel 64 (Intel's x86-64 implementation), the XD bit, and Virtualization Technology. All except the E5405 and L5408 also feature Demand Based Switching.^[15][16] The supplementary character in front of the model-number represents the thermal rating: an L depicts a TDP of 40 W or 50 W, an E depicts 80 W whereas an X is 120 W TDP or above. The speed of 3.00 GHz comes as four models, two models with 80 W TDP two other models with 120 W TDP with 1333 MHz or 1600 MHz front-side bus respectively. The fastest Harpertown is the X5492 whose TDP of 150 W is higher than those of the Prescott-based Xeon DP but having twice as many cores. (The X5482 is also sold under the name "Core 2 Extreme QX9775" for use in the Intel SkullTrail system.)

Intel 1600 MHz front-side bus Xeon processors will drop into the Intel 5400 (Seaburg) chipset whereas several mainboards featuring the Intel 5000/5200-chipset are enabled to run the processors with a 1333 MHz front-side bus speed. Seaburg features support for dual PCIe 2.0 x16 slots and up to 128 GB of memory.^[17][18]

Nehalem-based Xeon[edit]

3400-series "Lynnfield"[edit]

Main article: Lynnfield (microprocessor)

List: List of Intel Xeon microprocessors#"Lynnfield" (45 nm)

Xeon 3400-series processors based on Lynnfield fill the gap between the previous 3300-series "Yorkfield" processors and the newer 3500-series "Bloomfield". Like Bloomfield, they are quad-core single-package processors based on the Nehalem microarchitecture, but were introduced almost a year later, in September 2009. The same processors are marketed for mid-range to high-end desktops systems as Core i5 and Core i7. They have two integrated memory channels as well asPCI Express and Direct Media Interface (DMI) links, but no QuickPath Interconnect (QPI) interface.

3400-series "Clarkdale"[edit]

At low end of the 3400-series is not a Lynnfield but a Clarkdale processor, which is also used in the Core i3-500 and Core i5-600 processors as well as the Celeron G1000 and G6000 Pentium series. A single model was released in March 2010, the Xeon L3406. Compared to all other Clarkdale-based products, this one does not support integrated graphics, but has a much lower thermal design power of just 30 W. Compared to the Lynnfield-based Xeon 3400 models, it only offers two cores.

3500-series "Bloomfield"[edit]

Main article: Bloomfield (microprocessor)

List: List of Intel Xeon microprocessors#"Bloomfield" (45 nm)

Bloomfield is the codename for the successor to the Xeon Core microarchitecture, is based on the Nehalem microarchitecture and uses the same 45 nmmanufacturing methods as Intel's Penryn. The first processor released with the Nehalem architecture is the desktop Intel Core i7, which was released in November 2008. This is the server version for single CPU systems. This is a single-socket Intel Xeon processor. The performance improvements over previous Xeon processors are based mainly on:

• Integrated memory controller supporting three memory channels of DDR3 UDIMM (Unbuffered) or RDIMM (Registered)
• A new point-to-point processor interconnect QuickPath, replacing the legacy front side bus
• Simultaneous multithreading by multiple cores and hyper-threading (2× per core).

List: List of Intel Xeon microprocessors#"Beckton" (45 nm)

Beckton or Nehalem-EX (EXpandable server market) is a Nehalem-based processor with up to eight cores and uses buffering inside the chipset to support up to 16 standard DDR3 DIMMS per CPU socket without requiring the use of FB-DIMMS.^[23]Unlike all previous Xeon MP processors, Nehalem-EX uses the new LGA 1567 package, replacing the Socket 604 used in the previous models, up to Xeon 7400 "Dunnington". The 75xx models have four QuickPath interfaces, so it can be used in up-to eight-socket configurations, while the 65xx models are only for up to two sockets. Designed by the Digital Enterprise Group (DEG) Santa Clara and Hudson Design Teams, Beckton is manufactured on the P1266 (45 nm) technology. Its launch in March 2010 coincided with that of its direct competitor, AMD's Opteron 6xxx "Magny-Cours".^[24]

Most models limit the number of cores and QPI links as well as the L3 Cache size in order to get a broader range of products out of the single chip design.

E7-x8xx-series "Westmere-EX"[edit]

List: List of Intel Xeon microprocessors#"Westmere-EX" (32 nm) Expandable

Westmere-EX is the follow-on to Beckton/Nehalem-EX and the first Intel Chip to have ten CPU cores. The microarchitecture is the same as in the six-core Gulftown/Westmere-EP processor, but it uses the LGA 1567 package like Beckton to support up to eight sockets.

Starting with Westmere-EX, the naming scheme has changed once again, with "E7-xxxx" now signifying the high-end line of Xeon processors using a package that supports larger than two-CPU configurations, formerly the 7xxx series. Similarly, the 3xxx uniprocessor and 5xxx dual-processor series turned into E3-xxxx and E5-xxxx, respectively, for later processors.

List: List of Intel Xeon microprocessors#"Sandy Bridge" (32 nm)

The Xeon E3-12xx line of processors, introduced in April 2011, uses the Sandy Bridge chips that are also the base for the Core i3/i5/i7-2xxx and Celeron/Pentium Gxxx products using the same LGA 1155 socket, but with a different set of features disabled. Notably, the Xeon variants include support for ECC memory, VT-d andtrusted execution that are not present on the consumer models, while only some Xeon E3 enable the integrated GPU that is present on Sandy Bridge. Like its Xeon 3400-series predecessors, the Xeon E3 only supports operation with a single CPU socket and is targeted at entry-level workstations and servers. The CPUID of this processor is 0206A7h, the product code is 80623.

The Xeon E5-16xx processors follow the previous Xeon 3500/3600-series products as the high-end single-socket platform, using the LGA 2011 package introduced with this processor. They share the Sandy Bridge-E platform with the single-socket Core i7-38xx and i7-39xx processors. The CPU chips have no integrated GPU but eight CPU cores, some of which are disabled in the entry-level products. The Xeon E5-26xx line has the same features but also enables multi-socket operation like the earlier Xeon 5000-series and Xeon 7000-series processors.

Introduced in May 2013, Xeon E3 v3 is the first Haswell microarchitecture based Xeon. It uses the new LGA 1150 socket, which was introduced with the desktop Core i5/i7 Haswell processors and is not compatible with the LGA 1155 that was used in Xeon E3 and E3 v2. As before, the main difference between the desktop and server versions is added support for ECC memory in the Xeon branded parts. The main benefits of the new microarchitecture are better power efficiency and a faster GPU.
