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

Xeon - Wikipedia, the free encyclopedia

http://en.wikipedia.org/w/index.php?title=Xeon&printable=yes
The first Xeon-branded processor was the Pentium II Xeon (code-named
"Drake"). It was released in 1998, replacing the Pentium 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
A 450 MHz Pentium II Xeon with a
512 KB L2 cache. The cartridge cover
process and packaged in a cavity-down wire-bonded land grid array
has been removed.
(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
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 second version, named "Cascades", was based on the Pentium III
"Coppermine" core. The "Cascades" Xeon used a 133 MT/s 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 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)
Foster
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
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
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.
Gallatin
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 Xeon branded Prestonia
and Gallatin were designated 80532, like Northwood.
Xeon (DP) & Xeon MP (64-bit)
Nocona and Irwindale
Main article: Pentium 4#Prescott
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 to AMD64) 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 (http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2591) showed
that AMD's Opteron still outperformed Irwindale. Both of these Prescott-derived Xeons have the product code
80546.

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.
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 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.

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 architecture 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.

LV (ULV), "Sossaman"
23-03-2010 16:52

9 of 22
http://en.wikipedia.org/w/index.php?title=Xeon&printable=yes
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-/ultralow-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 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 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.

On 26 June 2006, Intel released the dual-core CPU (Xeon
branded 5100 series) codenamed Woodcrest (product code
80556); it was the first Intel Core microarchitecture processor
to be launched on the market. It is a server and workstation
version of the Intel Core 2 processor. Intel claims that it
provides an 80% boost in performance, while reducing power
consumption by 20% relative to the Pentium D.
Most models have a 1333 MT/s FSB, except for the 5110 and
5120, which have a 1066 MT/s FSB. The fastest processor
(5160) operates at 3.0 GHz. All Woodcrests use LGA 771
and all except two models have a TDP of 65 W. The 5160
has a TDP of 80 W and the 5148LV (2.33 GHz) has a TDP of
40 W. The previous generation Xeons had a TDP of 130 W.
All models support Intel 64 (Intel's x86-64 implementation),
the XD bit, and Virtualization Technology, with the "Demand
Based Switching" power management option only on
Dual-Core Xeon 5140 or above. Woodcrest has 4 MB of
shared L2 Cache.

The 7200 series, codenamed Tigerton (product code 80564) is an MP-capable processor, similar to the 7300
series, but, in contrast, only one core is active on each silicon chip, and the other one is turned off (blocked),
resulting as a dual-core capable processor. [2] (http://www.theregister.co.uk/2006/10/23/intel_shows_tigerton/)

Main article: Yorkfield (microprocessor)
Intel released relabeled versions of its quad-core Core 2 Quad Yorkfield Q9400 and Q9x50 processors as the
Xeon 3300-series (product code 80569). It comprised two separate dual-core dies next to each other in one CPU
package and manufactured in a 45 nm process. The models are the X3320, X3350, X3360 and X3370, running
at 2.50 GHz, 2.66 GHz, 2.83 GHz and 3.0 GHz, respectively. The L2 cache is a unified 6 MB per die (except for
the X3320 with a smaller 3 MB L2 cache per die), and a front-side bus of 1333 MHz. All models feature Intel
64 (Intel's x86-64 implementation), the XD bit, and Virtualization Technology, as well as "Demand Based
Switching".
The Yorkfield-CL (product code 80584) variant of these processors are X3323, X3353 and X3363, a reduced
TDP of 80W and are made for single-CPU LGA 771 systems instead of LGA 775, which is used in all other
Yorkfield processors. Otherwise they are identical to their Yorkfield counterparts.
5300-series "Clovertown"
23-03-2010 16:52
Xeon - Wikipedia, the free encyclopedia
14 of 22
http://en.wikipedia.org/w/index.php?title=Xeon&printable=yes
A quad-core (2x2) successor of the Woodcrest for DP
segment, consisting of two dual-core Woodcrest chips in one
package similarly to the dual-core Pentium D branded CPUs
(two single-core chips) or the quad-core Kentsfield. All
Clovertowns use the LGA 771 package. The Clovertown has
been usually implemented with two Woodcrest dies on a
multi-chip module, with 8 MB of L2 cache (4 MB per die).
Like Woodcrest, lower models use a 1066 MT/s FSB, and
higher models use a 1333 MT/s FSB. Intel released
Clovertown, product code 80563, on 14 November 2006[13]
with models E5310, E5320, E5335, E5345, and X5355,
ranging from 1.6 GHz to 2.66 GHz. All models support:
MMX, SSE, SSE2, SSE3, SSSE3, Intel 64, XD bit (an NX bit
implementation), Intel VT. The E and X designations are
borrowed from Intel's Core 2 model numbering scheme; an
ending of -0 implies a 1066 MT/s FSB, and an ending of -5
implies a 1333 MT/s FSB.[12] All models have a TDP of
80 W with the exception of the X5355, which has a TDP of
120 W. A low-voltage version of Clovertown with a TDP of
50 W has a model numbers L5310, L5320 and L5335
(1.6 GHz, 1.86 GHz and 2.0 GHz respectively). The 3.0 GHz
X5365 arrived in July 2007, and became available in the
Apple Mac Pro [6] (http://www.apple.com/macpro) on 4
April 2007.[7] (http://tgdaily.com/2006/09
/26/intel_core_2_quad_announcement/) [14] The X5365
performs up to around 38 GFLOPS in the LINPACK
benchmark. [8] (http://www.intel.com/performance/server

http://en.wikipedia.org/w/index.php?title=Xeon&printable=yes
On 11 November 2007 Intel presented Yorkfield based Xeons
- called Harpertown (product code 80574) - to the public.[9]
(http://download.intel.com/design/xeon/datashts/318589.pdf)
This family consists of dual die quad-core CPUs
manufactured on a 45 nm process and featuring 1333 MHz to
1600 MHz front-side buses, with TDP rated from 50 W to
150 W depending on the model. These processors fit in the
LGA 771 package. All models feature Intel 64 (Intel's x86-64
implementation), the XD bit, and Virtualization Technology,
as well as the Demand Based Switching, except the E5405,
which lacks this feature[15]. The supplementary character in
front of the model-number represents the thermal rating: an L
depicts an TDP of 50 W, an E depicts 80 W whereas a 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.)

is a four-socket (packaged in Socket 604) and more 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 [10]
(http://www.intel.com/pressroom/archive/releases
/20070905comp.htm?iid=pr1_releasepri_20070905m) , and is
currently shipping.
The 7300 series uses Intel's Caneland (Clarksboro) 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.
The 7xxx series is aimed at the large server market,
supporting configurations of up to 32 CPUs per host.

cores and power envelopes from 23 to 85 watts.[20]
The uni-processor version without QPI comes as LC35xx and
EC35xx, while the dual-processor version is sold as LC55xx
and EC55xx and uses QPI for communication between the
processors. Both versions use a DMI link to communicate
with the 3420 that is also used in the 3400-series Lynfield
Xeon processors, but use an LGA 1366 package that is
otherwise used for processors with QPI but no DMI or PCI
Express links. The CPUID code of both Lynnfield and Jasper
forest is 106Ex, i.e. family 6, model 30.
The Celeron P1053 belongs into the same family as the
LC35xx series, but lacks some RAS features that are present
in the Xeon version.

6500/7500-series "Beckton"
Xeon C35xx (UP)
Brand name(s)
Beckton or Nehalem-EX (EXpandable server market) is a
Nehalem-based processor with 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.[21] It has four or more QuickPath interfaces, so
it can be used in at least quad-socket configurations.
Designed by the Digital Enterprise Group (DEG) Santa Clara
and Hudson Design Teams, Beckton will be manufactured on
the P1266 (45 nm) technology. It is expected to be launched
in Q1 2010.[22]
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.

3600/5600-series "Gulftown"
Main article: Gulftown (microprocessor)
Gulftown or Westmere-EP, a six-core 32 nm Nehalem-based processor, is the basis for the Xeon 36xx and
56xx series and the Core i7-980X. It launched in the first quarter of 2010. The 36xx-series follows the
35xx-series Bloomfield uni-processor model while the 56xx-series follows the 55xx-series Gainestown
dual-processor model and both are socket compatible to their predecessors.
Supercomputers based on Xeon processors that have been in the top ten of the Top500 fastest supercomputers
in the world are:
After upgrades from Pentium Pro to Xeon, ASCI Red reclaimed its #1 spot in 1999 with a speed of 2.4
TFLOPS.[24]
an Intel Xeon system at SGI in Chippewa Falls, Wisconsin. Machine: SGI Altix ICE 8200 system with
3584 Quad-Core Clovertown processors at 3.0 GHz and InfiniBand interconnect. This supercomputer was
listed in third place in November 2007, ahead of the fastest Itanium and Opteron-based supercomputers
but behind two PowerPC-based Blue Gene systems.[25]
Xeon processor based system, in the top 20 of the fastest systems by memory bandwidth as measured by
STREAM benchmark:[26]
an Intel Xeon virtual SMP system leveraging ScaleMP's Versatile SMP (vSMP) architecture with 128
cores and 1TB RAM.[27] This system aggregates 16 Stoakley platform (Seaburg chipset) systems with
total of 32 Harpertown processors.
