targeted at the non-consumer [[workstation]], [[Server (computing)|server]], and [[embedded system|embedded]] markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for [[ECC memory|error correction code (ECC) memory]], higher [[Multi-core processor|core]] counts, more [[PCI Express]] lanes, support for larger amounts of RAM, larger [[cache memory]] and extra provision for enterprise-grade [[reliability, availability and serviceability]] (RAS) features responsible for handling hardware exceptions through the [[Machine Check Architecture]] (MCA). They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the [[machine-check exception]] (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the [[Intel Ultra Path Interconnect|Ultra Path Interconnect]] (UPI) bus, which replaced the older [[Intel QuickPath Interconnect|QuickPath Interconnect]] (QPI) bus. [[File:Intel Xeon E5-1620, front and back.jpg|thumb|center|Intel Xeon E5-1620's front and back]] == Branding == The ''Xeon'' brand has been maintained over several generations of [[IA-32]] and [[x86-64]] processors. The P6-based models added the ''Xeon'' moniker to the end of the name of their corresponding desktop processor, but all models since 2001 used the name ''Xeon'' on its own. The ''Xeon'' CPUs generally have more [[CPU cache|cache]] and [[Multi-core processor|cores]] than their desktop counterparts in addition to multiprocessing capabilities. {{Multiple image|total_width = 300 | align = center | direction = horizontal | perrow = 2 / 2 | width = 150 | caption_align = center | image_gap = 10 | header_align = center | header = Xeon branding | image1 = Intel Xeon (2020).svg | width1 = 150 | alt1 = | caption1 = (2020–2023) | image2 = Intel-Xeon-Badge-2024.jpg | width2 = 150 | alt2 = | caption2 = (2024–present) }} === Xeon Scalable === The Xeon Scalable brand for high-performance server was introduced in May 2017 with the Skylake-based Xeon Platinum 8100 series. Xeon Scalable processors range from dual socket to 8 socket support. Within the Xeon Scalable brand, there exists the hierarchy of Xeon Bronze, Silver, Gold and Platinum. {{Multiple image|total_width = 600 | align = center | direction = horizontal | perrow = 4 / 4 | width = 150 | caption_align = center | image_gap = 10 | header_align = center | header = Xeon Scalable branding | image1 = Intel-Xeon-Bronze-Badge-2017.png | width1 = 150 | alt1 = | caption1 = Xeon Bronze <br/> (2017–2019) | image2 = Intel-Xeon-Silver-Badge-2017.png | width2 = 150 | alt2 = | caption2 = Xeon Silver <br/> (2017–2019) | image3 = Intel-Xeon-Gold-Badge-2017.png | width3 = | alt3 = | caption3 = Xeon Gold <br/> (2017–2019) | image4 = Intel-Xeon-Platinum-Badge-2017.png | width4 = 150 | alt4 = | caption4 = Xeon Platinum <br/> (2017–2019) | image5 = Intel-Xeon-Bronze-Badge-2020.png | width5 = 150 | alt5 = | caption5 = Xeon Bronze <br/> (2020–2023) | image6 = Intel-Xeon-Silver-Badge-2020.png | width6 = 150 | alt6 = | caption6 = Xeon Silver <br/> (2020–2023) | image7 = Intel-Xeon-Gold-Badge-2020.png | width7 = 150 | alt7 = | caption7 = Xeon Gold <br/> (2020–2023) | image8 = Intel-Xeon-Platinum-Badge-2020.png | width8 = 150 | alt8 = | caption8 = Xeon Platinum <br/> (2020–2023) }} In April 2024, Intel announced at its Vision event that the Xeon Scalable brand would be retired, beginning with 6th generation Xeon processors codenamed [[Sierra Forest]] and [[Granite Rapids]] that will now be referred to as "Xeon 6" processors.<ref>{{cite web |last=Chiapetta |first=Marco |date=April 9, 2024 |title=Intel Unveils Powerful, Efficient Gaudi 3 AI Accelerator And New Xeon 6 Processors At Vision 2024 |url=https://www.forbes.com/sites/marcochiappetta/2024/04/09/intel-unveils-efficient-gaudi-3-ai-accelerator-and-new-xeons-at-vision/ |website=Forbes |language=en-US |access-date=April 22, 2024}}</ref> This change brings greater emphasis on processor generation numbers.<ref>{{cite web |last=Bonshor |first=Gavin |date=April 9, 2024 |title=Intel Unveils New Branding For 6th Generation Xeon Processors: Intel Xeon 6 |url=https://www.anandtech.com/show/21339/intel-unveils-new-branding-for-6th-generation-xeon-processors-intel-xeon-6 |website=AnandTech |language=en-US |access-date=April 22, 2024}}</ref> === Xeon 6 === With the launch of Intel's [[Sierra Forest]] line of processors, branding for mainstream server processors switched to Xeon #, with the # being the generation of the processor, such as Xeon 6 for the 6th generation of Xeon processors, this naming convention also carries over to the Granite Rapids line of server CPUs.<ref name=":0">{{Cite web |last=Kennedy |first=Patrick |date=2024-06-04 |title=Intel Xeon 6 6700E Sierra Forest Shatters Xeon Expectations |url=https://www.servethehome.com/intel-xeon-6-6700e-sierra-forest-shatters-xeon-expectations/ |access-date=2024-10-03 |website=ServeTheHome |language=en-US}}</ref> Xeon 6 is split into two product lines, the E series and P series, which, respectively, are all E core and all P core designs.

It was first introduced in August 2017 with the release of the [[Skylake_(microarchitecture)#Workstation_processors|Skylake]]-based Xeon W-2100 series workstation processors. With Sapphire Rapids-WS workstation processors that launched in March 2023, Intel introduced tiers within Xeon W. Xeon w3, w5, w7 and w9 was designed to emulate the Core i3, i5, i7 and i9 branding that Intel had been using for its desktop processors. == Overview == Some shortcomings that make Xeon processors unsuitable for most consumer-grade desktop PCs include lower [[clock rate]]s at the same price point (since servers run more tasks in parallel than desktops, core counts are more important than clock rates), and, usually, the lack of an integrated [[graphics processing unit]] (GPU). Processor models prior to [[Sapphire Rapids#Sapphire Rapids-WS (Workstation)|Sapphire Rapids-WS]] lack support for [[overclocking]] (with the exception of [[Skylake (microarchitecture)#Xeon High-end desktop processors (Skylake-X)|Xeon W-3175X]]). Despite such disadvantages, Xeon processors have always had popularity among some desktop users (video editors and other [[power user]]s), mainly due to higher core count potential, and higher performance to price ratio vs. the [[Core i7]] in terms of total computing power of all cores. Since most Intel Xeon CPUs lack an integrated [[graphics processing unit|GPU]], systems built with those processors require a discrete graphics card or a separate GPU if [[computer monitor]] output is desired. Intel Xeon is a distinct product line from the similarly named Intel [[Xeon Phi]]. The first-generation Xeon Phi is a completely different type of device more comparable to a graphics card; it is designed for a [[PCI Express]] slot and is meant to be used as a multi-core coprocessor, like the [[Nvidia Tesla]]. In the second generation, Xeon Phi evolved into a main processor more similar to the Xeon. It conforms to the same socket as a Xeon processor and is x86-compatible; however, as compared to Xeon, the design point of the Xeon Phi emphasizes more cores with higher memory bandwidth. {| class="wikitable" style="border:0;

It was released in 1998, replacing the [[Pentium Pro]] in Intel's high-end server lineup. The Pentium II Xeon was a "''[[Deschutes (microprocessor)|Deschutes]]''" [[Pentium II]] (and shared the same product code: 80523) with a full-speed 512 kB (1 kB = 1024 B), 1 MB (1 MB = 1024 kB = 1024<sup>2</sup> B), or 2 MB [[CPU cache|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 mm{{sup|2}}) die fabricated in a 0.35 μm four-layer metal CMOS process and packaged in a cavity-down wire-bonded [[land grid array]] (LGA).<ref>{{cite conference |last=Bateman |first=B. |title=A 450MHz 512 kB Second-Level Cache with a 3.6GB/s Data Bandwidth |conference=[[International Solid-State Circuits Conference]] | date=February 1998 |pages=358–359 |doi=10.1109/ISSCC.1998.672528 |isbn=0-7803-4344-1 |s2cid=21384417 |display-authors=etal}}</ref> The additional cache required a larger module and thus the Pentium II Xeon used a larger slot, [[Slot 2]].

Reflecting the incremental changes from the Pentium II "''[[Deschutes (microprocessor)|Deschutes]]''" core to the Pentium III "''[[Katmai (microprocessor)|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 for '''Tanner''' mirrored that of ''Katmai''; 80525. The second version, named "'''Cascades'''", was based on the Pentium III "''[[Coppermine (microprocessor)|Coppermine]]''" core. The "'''Cascades'''" Xeon used a 133 MT/s front side 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 or octa-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. The product code for '''Cascades''' mirrored that of ''Coppermine''; 80526. == NetBurst-based Xeon {{anchor|Netburst-based Xeon}} == === Xeon (DP) and Xeon MP (32-bit) === ==== Foster ==== {{main|List of Intel NetBurst-based Xeon microprocessors#"Foster" (180 nm)|List of Intel NetBurst-based Xeon microprocessors#"Foster MP" (180 nm)|l2=§ "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|NetBurst microarchitecture]], "'''Foster'''", was slightly different from the desktop [[Pentium 4]] ("''[[Pentium 4#Willamette|Willamette]]''"). It was a decent{{Clarify|date=March 2017}} 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|Athlon MP]]{{Examples|date=March 2017}}. Combined with the need to use expensive [[RDRAM|Rambus Dynamic RAM]], the Foster's sales were somewhat unimpressive{{Examples|date=March 2017}}. 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 512 KB or 1 MB L3 cache and the Jackson [[Hyper-threading|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 ==== {{main|List of Intel NetBurst-based Xeon microprocessors#"Prestonia" (130 nm)}} In 2002 Intel released a [[130 nanometer|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 "''[[Pentium 4#Northwood|Northwood]]''" Pentium 4 core. A new server chipset, [[Intel Xeon chipsets#NetBurst-based Xeon chipsets|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 a new socket and two 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. ==== {{Anchor|Gallatin}} Gallatin ==== {{Infobox CPU | name = Gallatin | image =Xeon_DP_Gallatin_(SL7AE),_Socket_604.jpg | caption = | produced-start = March 2003 | produced-end = 2004 | slowest = 1.50 | fastest = 3.20 | slow-unit = GHz | fast-unit = GHz | fsb-slowest = 400 | fsb-fastest = 533 | fsb-slow-unit = MT/s | fsb-fast-unit = MT/s | size-from = 130 nm | size-to = | soldby = | designfirm = | manuf1 = | core1 = | sock1 = | pack1 = [[Socket 603]] [[Socket 604]] | code = 80537 | cpuid = 0F7x | brand1 = Xeon | arch = [[x86-16]], [[IA-32]] | microarch = [[NetBurst]] | numcores = 1 | l1cache = 8 kB + 12 kuOps trace cache | l2cache = 512 kB | l3cache = 1 MB, 2 MB, 4 MB | application = DP and MP Server }} {{main|List of Intel NetBurst-based Xeon microprocessors#"Gallatin" (130 nm)|List of Intel NetBurst-based Xeon microprocessors#"Gallatin" (130 nm) 2|l2=§ "Gallatin" MP (130 nm)}} Subsequent to the ''Prestonia'' was the "'''Gallatin'''", which had an L3 cache of 1 MB or 2 MB. Its Xeon MP version, which succeeded ''Foster MP'', 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) and Xeon MP (64-bit)=== ====Nocona and Irwindale==== {{main|Pentium 4#Prescott|List of Intel NetBurst-based Xeon microprocessors#"Nocona" (90 nm)|List of Intel NetBurst-based Xeon microprocessors#"Irwindale" (90 nm)|l3=§ "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 to [[AMD64]]) in the [[90 nanometer|90 nm]] version of the Pentium 4 ("''[[Pentium 4#Prescott|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#PCI Express 1.0a|PCI Express 1.0a]], [[DDR2 SDRAM|DDR2]] and [[SATA#SATA revision 1.0 (1.5 Gbit/s, 150 MB/s, Serial ATA-150)|Serial ATA 1.0a]]. 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 [https://web.archive.org/web/20051228212744/http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2591 tests] showed that AMD's Opteron still outperformed ''Irwindale''. Both of these Prescott-derived Xeons have the product code 80546. ==== Cranford and Potomac ==== {{main|Pentium 4#Prescott|List of Intel NetBurst-based Xeon microprocessors#"Cranford" (90 nm)|List of Intel NetBurst-based Xeon microprocessors#"Potomac" (90 nm)|l3=§ "Potomac" (90 nm)}} 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" ==== {{main|List of Intel NetBurst-based Xeon microprocessors#"Paxville DP" (90 nm)|Pentium D#Smithfield}} {{Infobox CPU | name = Paxville | image = | image_size = | caption = | produced-start = October 2005 | produced-end = August 2008 | slowest = 2.667 | fastest = 3.0 | slow-unit = GHz | fast-unit = GHz | fsb-slowest = 667 | fsb-fastest = 800 | fsb-slow-unit = MT/s | fsb-fast-unit = MT/s | size-from = 90 nm | size-to = | soldby = | designfirm = | manuf1 = | core1 = | sock1 = | pack1 = [[Socket 604]] | code = 80551, 80560 | cpuid = 0F48 | brand1 = Xeon | arch = [[x86-16]], [[IA-32]], [[x86-64]] | microarch = [[NetBurst]] | numcores = 2 | l1cache = | l2cache = 2×2 MB | l3cache = | application = DP Server, MP Server }} The first [[Multi-core (computing)|dual-core]] CPU branded Xeon, codenamed '''Paxville DP''', product code 80551, was released by Intel on October 10, 2005. Paxville DP had [[NetBurst|NetBurst microarchitecture]], and was a dual-core equivalent of the single-core [[#Nocona and Irwindale|Irwindale]] (related to the [[Pentium D]] branded "[[Pentium D#Smithfield|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 nanometer|90 nm process]]. ==== 7000-series "Paxville MP" ==== {{main|List of Intel NetBurst-based Xeon microprocessors#"Paxville MP" (90 nm)}} An MP-capable version of Paxville, codenamed '''Paxville MP''', product code 80560, was released on November 1, 2005. There are two versions: one with 2 MB of L2 cache (1 MB per core), and one with 4 MB of L2 (2 MB per core). Paxville MP, called the dual-core Xeon 7000-series, was produced using a 90 nm process. Paxville MP clock ranges between 2.67 GHz and 3.0 GHz (model numbers 7020–7041), with some models having a 667 MT/s FSB, and others having an 800 MT/s FSB. {| class="wikitable sortable" |- ! scope="col" | Model ! scope="col" | Speed ! scope="col" | L2 cache ! scope="col" | FSB ! scope="col" | TDP |- | 7020 | 2.66 GHz | rowspan="2" | 2 × 1 MB | 667 MT/s | rowspan="4" | 165 W |- | 7030 | 2.80 GHz | 800 MT/s |- | 7040 | rowspan="2" | 3.00 GHz | rowspan="2" | 2 × 2 MB | 667 MT/s |- | 7041 | 800 MT/s |} ====7100-series "Tulsa"==== {{main|List of Intel NetBurst-based Xeon microprocessors#"Tulsa" (65 nm)}} {{Infobox CPU | name = Tulsa | image = | image_size = | caption = | produced-start = August 2006 | produced-end = August 2008 | slowest = 2.50 | fastest = 3.50 | slow-unit = GHz | fast-unit = GHz | fsb-slowest = 667 | fsb-fastest = 800 | fsb-slow-unit = MT/s | fsb-fast-unit = MT/s | size-from = 65 nm | size-to = | soldby = | designfirm = | manuf1 = | core1 = | sock1 = | pack1 = [[Socket 604]] | code = 80550 | cpuid = 0F68 | brand1 = Xeon 71xx | arch = [[x86-16]], [[IA-32]], [[x86-64]] | microarch = [[NetBurst]] | numcores = 2 | l1cache = | l2cache = 2×1 MB | l3cache = 16 MB | application = MP Server }} Released on August 29, 2006,<ref>{{cite press release|url=https://newsroom.intel.com/news-releases/new-high-end-intel-server-processors-expand-performance-leadership|title=New High-End Intel Server Processors Expand Performance Leadership|publisher=Intel|date=August 29, 2006}}</ref> the 7100 series, codenamed '''Tulsa''' (product code 80550), is an improved version of Paxville MP, built on a 65 nm process, with 2 MB of L2 cache (1 MB per core) and up to 16 MB of L3 cache.

Released as the Dual-Core Xeon 5000-series, Dempsey is a [[NetBurst|NetBurst microarchitecture]] processor produced using a [[65 nanometer|65 nm process]], and is virtually identical to Intel's "[[Pentium D#Presler|Presler]]" [[Pentium Extreme Edition]], except for the addition of SMP support, which lets Dempsey operate in dual-processor systems.

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. {| class="wikitable sortable" |- ! scope="col" | Model ! scope="col" | Speed (GHz) ! scope="col" | L2 cache ! scope="col" | FSB ! scope="col" | TDP |- | 5020 | 2.50 GHz | rowspan="8" | 2 × 2 MB | rowspan="4" | 667 MT/s | rowspan="4" | 95 W |- | 5030 | 2.66 GHz |- | 5040 | 2.83 GHz |- | 5050 | 3.00 GHz |- | 5060 | rowspan="2" | 3.20 GHz | rowspan="4" | 1.07 GT/s | 130 W |- | 5063 | 95 W |- | 5070 | 3.46 GHz | rowspan="2" | 130 W |- | 5080 | 3.73 GHz |} == Pentium M (Yonah) based Xeon == === {{Anchor|Sossaman}}LV (ULV), "Sossaman" === {{main|List of Intel Pentium M (Yonah)-based Xeon microprocessors#"Sossaman" (65 nm)}} {{Infobox CPU | name = Sossaman | image =2.00_GHz_Xeon_LV_Sossaman_processor.jpg | caption = | produced-start = 2006 | produced-end = 2008 | slowest = 1.667 | slow-unit = GHz | fastest = 2.167 | fast-unit = GHz | fsb-slowest = 667 | fsb-fastest = | fsb-slow-unit = MT/s | fsb-fast-unit = MT/s | size-from = 65 nm | size-to = | soldby = | designfirm = | manuf1 = | core1 = | sock1 = | pack1 = [[Socket M]] | code = 80539 | cpuid = 06Ex | brand1 = Xeon | arch = [[x86-16]], [[IA-32]], [[x86-64]] | microarch = [[Enhanced Pentium M (microarchitecture)|Enhanced Pentium M]] | numcores = 2 | l1cache = | l2cache = 2 MB | l3cache = | application = DP Server }} On March 14, 2006, Intel released a dual-core processor codenamed '''Sossaman''' and branded as ''Xeon'' LV (low-voltage).

The ''Sossaman'' was a low-/ultra-low-power and double-processor capable CPU (like [[AMD Quad FX platform|AMD Quad FX]]), based on the "''[[Yonah (microprocessor)|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|thermal design power]] (TDP) of 31 W (LV: 1.66 GHz, 2 GHz and 2.16 GHz) and 15 W (ULV: 1.66 GHz).<ref>{{cite web |title=Intel drops 32-bit dual-core LV processors |url=http://www.tgdaily.com/content/view/33150/135/ |publisher=TG Daily |access-date=July 31, 2007}}</ref> 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 it 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 (microprocessor)|Merom]] MP''" was to be a drop-in upgrade to enable ''Sossaman''-based servers to upgrade to 64-bit capability.

Most models have a 1333{{nbsp}}MT/s FSB, except for the 5110 and 5120, which have a 1066{{nbsp}}MT/s FSB. The fastest processor (5160) operates at 3.0{{nbsp}}GHz. All Woodcrest processors use the [[LGA 771]] (Socket J) socket and all except two models have a TDP of 65{{nbsp}}W. The 5160 has a TDP of 80{{nbsp}}W and the 5148LV (2.33{{nbsp}}GHz) has a TDP of 40{{nbsp}}W. The previous generation Xeons had a TDP of 130{{nbsp}}W.

By keeping data and instructions local to the "partition" of CPU which is processing them, thus decreasing the LLC access latency, COD brings performance improvements to NUMA-aware operating systems and applications.<ref>{{cite web |last=De Gelas |first=Johan |date=September 8, 2014 |title=Intel Xeon E5 Version 3, Up to 18 Haswell EP Cores: The Magic Inside the Uncore |url=http://www.anandtech.com/show/8423/intel-xeon-e5-version-3-up-to-18-haswell-ep-cores-/4 |website=AnandTech |language=en-US |access-date=September 9, 2014}}</ref> === {{Anchor|E7-V3}}E7-48xx/88xx v3 series "Haswell-EX" === {{main|List of Intel Haswell-based Xeon microprocessors#"Haswell-EX" (22 nm) Expandable}} Introduced in May 2015, '''Xeon E7-48xx v3''' and '''Xeon E7-88xx v3''' series provide higher core counts, higher per-core performance and improved reliability features, compared to the previous Xeon E7 v2 generation.
