The Xeon brand refers to many families of Intel's x86 multiprocessing CPUs – for dual-processor (DP) and multi-processor (MP) configuration on a single motherboard targeted at non-consumer markets of server and workstation computers, and also at blade servers and embedded systems. 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. Intel's (non-x86) IA-64 processors are called Itanium, not Xeon.

Pentium II Xeon

The first Xeon branded processor was released in 1998, named the Pentium II Xeon (codenamed "Drake"), as the replacement of the Pentium Pro. It was based on the 0.25 µm "Deschutes" core (P6 microarchitecture) branded Pentium II (sharing its 80523 product code), used either a 440GX (a dual-processor workstation chipset) or 450NX (quad-processor, or oct with additional logic) chipset, and differed from the Pentium II desktop CPU (Deschutes) in that its off-die L2 cache ran at full speed. It also used a larger slot known as slot 2. Cache sizes were 512 KB, 1 MB and 2 MB, and it used a 100 MT/s front side bus (FSB).

Pentium III Xeon

Pentium III Xeon logo

In 1999, the Pentium II Xeon was replaced by the Pentium III Xeon. The initial version, "Tanner", was just like its predecessor except for the addition of Streaming SIMD Extensions (SSE) and a few cache controller enhancements found in the "Katmai" Pentium III. The second version, the "Cascades", was based on the "Coppermine" core branded Pentium III. The Cascades had a 133 MT/s bus and only a 256 KB on-die L2 cache resulting in almost the same capabilities, as the Coppermine desktop Slot 1 versions (branded Pentium III) also 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 MT/s, though in practice the cache was able to offset this. Product codes for Tanner and Cascades mirrored that of Katmai and Coppermine; 80525 and 80526 respectively.

Xeon (DP) & Xeon MP (32-bit)

In mid-2001, the Xeon brand was introduced ("Pentium" was dropped from the name). The initial variant that used the new NetBurst architecture, "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 Cascade 2 MB core and AMD's Athlon MP. Combined with the need to use expensive Rambus Dynamic RAM, the Foster's sales were somewhat unimpressive. The Intel NetBurst Microarchitecture, called P68 inside Intel, was the successor to the P6 microarchitecture in the x86 family of CPUs made by Intel. ... The Pentium 4[1] brand refers to Intels mainstream desktop and mobile single-core CPUs (introduced on November 20, 2000[2]) with the seventh-generation NetBurst architecture, which was the companys first all-new design since the Intel P6 of the Pentium Pro branded CPUs of 1995. ...

At most two Foster processors could be accommodated in an 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.

Hyper-Threading (HTT = Hyper Threading Technology) is Intels trademark for their implementation of the simultaneous multithreading technology on the Pentium 4 microarchitecture. ...


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. Also see: 2002 (number). ...

DDR SDRAM or double-data-rate synchronous dynamic random access memory is a type of memory integrated circuit used in computers. ...


Subsequent to the Prestonia was the "Gallatin", which had an L3 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 Foster shared the 80528 product code with Willamette; The Xeon branded Prestonia and Gallatin were designated 80532, like Northwood.


Xeon (DP) & Xeon MP (64-bit)

Due to a lack of success with Intel's Itanium and Itanium 2 processors, the 90 nm version of the Pentium 4 ("Prescott") was built with support for 64-bit instructions (called Intel 64, Intel's implementation of x86-64), and a Xeon version codenamed "Nocona" 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. The 90 nm node refers to the level of semiconductor process technology that was reached in the 2002-2003 timeframe, by most leading semiconductor companies, like Intel, Texas Instruments, IBM, and TSMC. The origin of the 90 nm value is historical, as it represents a 70% scaling every 2-3...

SATA redirects here. ...


A slightly updated core called "Irwindale" was released in early 2005, with twice the L2 cache of Nocona and able to reduce its clockspeeds during low processor demand. However, independent tests showed that AMD's Opteron still outperformed Irwindale.


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. All these Prescott-derived Xeons have the product code 80546.


Dual-Core Xeon

"Paxville DP"

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 architecture, 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 one 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.

LV (ULV), "Sossaman"

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 it was rated at a thermal design power (TDP) of 31 watts (LV: 1.66 and 2 GHz ) and 15 W (ULV: 1.66 GHz)[1]. 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 it did not support 64-bit operations, so it could not run 64-bit-only server software, such as Microsoft Exchange Server 2007, and therefore it was limited to only 16 GB of memory. A planned successor, codenamed "Merom MP" was to be a drop-in upgrade to allow 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 planned upgrades. is the 73rd day of the year (74th in leap years) in the Gregorian calendar. ...

Intel has one 1600 MHz dual-core Penryn based Xeon processor ready for launch – the E5272. The Xeon E5272 features a 3.4 GHz clock speed and is priced at $1,172. Intel has also pulled in the launch of all dual-core Xeon processors to Q4 2007, with the quad-core processors. The dual-core Xeon E5260 and E5205 will also launch in Q4, not the Q1 2008 date earlier roadmaps showed.


Intel 1600 MHz front-side bus Xeon processors will drop into the upcoming Seaburg chipset. Seaburg features support for dual PCIe 2.0 x16 slots and up to 128 GB of memory.[11][12]


7300-series "Tigerton"

The 7300 series, codenamed Tigerton is a four-socket (packaged in Socket 604) and greater capable quad-core processor, consisting of two dual core Core2 architecture silicon chips on a single ceramic module, similar to Intel's Xeon 5300 series Clovertown processor modules. It was announced on 5 September 2007 [9], and is expected to ship in the second half of 2007. Socket 604 is a motherboard socket for Intels Xeon processor. ... is the 248th day of the year (249th in leap years) in the Gregorian calendar. ... Year 2007 (MMVII) is the current year, a common year starting on Monday of the Gregorian calendar and the AD/CE era in the 21st century. ...


The 7300 series uses Intel's Caneland (Clarksbore) platform.


Intel claims the 7300 series Xeons offer more than twice the performance and more than three times the performance per watt as Intel's previous generation 7100 series. The 7300 series' Caneland chipset provides a point to point interface allowing the full front side bus bandwidth per processor.

Whitefield (cancelled)

A quad-core processor, partially based on Woodcrest, and would have used the new QuickPath Interconnect bus, a bus shared with the Itanium 2 processors of its generation (beginning with the "Tukwila" core). Whitefield would have had 16 MB of L2 cache, manufactured using the 65 nm process initially, and the 45 nm process later. The Intel QuickPath Interconnect or simply QuickPath [1][2] (formerly Common System Interface or CSI in short) is a point-to-point processor interconnect being developed by Intel, as a competitor to HyperTransport. ... The 65 nanometer (65 nm) process is (as of 2006) the most advanced lithographic node for volume semiconductor manufacturing, however it will soon be eclipsed when 45 nanometer lithography becomes commercially viable. ... The 45 nanometer (45 nm) process is the next milestone (to be commercially viable in mid 2007 to early 2008) in CMOS fabrication. ...


Whitefield was the first full processor being worked on at Whitefield, Bangalore, India. It was cancelled from the processor roadmap and replaced with Tigerton.[13][14] Whitefield is a hub in the North East of Bangalore in India. ... For other uses, see Bangalore (disambiguation). ...


Aliceton

Aliceton was a successor to Tigerton.[15] It has effectively been renamed Dunnington as the original Dunnington was based on the now cancelled Whitefield.


Dunnington

A 45 nm successor to Tigerton (formerly Aliceton), a four to eight (likely six) core processor.[16][17] Dunnington was originally based on Whitefield, but with Whitefield cancelled, Dunnington's details are less clear.[18]


5400-series Harpertown and 5200-series Wolfdale

Harpertown is said to be a 45 nm, quad-core processor based on Intel's upcoming Penryn microarchitecture with 12 MiB of L2 cache.[19] An older rumour stated that it was simply the 45 nm shrink of Woodcrest,[20] but that has since changed.[citation needed]


Harpertown, which will succeed the current 65 nm Clovertown processors (Xeon 5300 series), will receive 5400 sequence number, with X, E, and L letters indicating performance, regular and low-power versions of the CPU. A LINPACK benchmark shows that the a dual Harpertown system could sustain 80 GFLOPS and peak at 102 GFLOPS. [10] [11] LINPACK is a software library for performing numerical linear algebra on digital computers. ...


The mainstream lineup (80 watts) will reach from the E5405 with a clock speed in the low 2 GHz range up to the E5450 with 3.0 GHz. The X5460 will clock in at 3.16 GHz and will be rated at a thermal design power of 120 watts. The two highest models E5462 and E5472 will clock in at 2.8 and 3.0 GHz at new 1600MT/s FSB (provided with Seaburg chipset in the Stoakly platform planned at 2007-H2[21]) rated at TDP of 80 watts. Intel also plans to introduce two low-power versions codenamed Harpertown LV, rated at 50 watts, with 2.33 and 2.66 GHz speeds (L5410 and L5430). All Harpertown processors will include a 12 MiB L2 cache, up from 8 MiB in Clovertown. The front side bus besides E5462 and E5472 is expected to be a FSB1333 version across the board, while the slide published by VR-Zone still indicates that the E5405 could run at a slower clock speed.


The dual-core version of the CPU, code-named Wolfdale-DP, apparently will be available with processor speeds of 1.86 GHz, 3.33 GHz and 3.4 GHz at 1066/1333/1600 MT/s FSB, rated at 65/80/80 watts TDP respectively. There will also be a 3.16 GHz low-power version of the processor codenamed Wolfdale-LV, rated at 40 watts.


The socket type is expected to be 771, but it could be something else at higher frequencies.


Harpertown is expected to be launched on 11 November 2007.[22] Wolfdale is expected to launch late in Q4 of this year(2007).[23] is the 315th day of the year (316th in leap years) in the Gregorian calendar. ... Year 2007 (MMVII) is the current year, a common year starting on Monday of the Gregorian calendar and the AD/CE era in the 21st century. ...
