Detailed Specifications of the Intel Xeon E5-2600v3 “Haswell-EP” Processors

This article provides in-depth discussion and analysis of the 22nm Xeon E5-2600v3 series processors (formerly codenamed “Haswell-EP”). “Haswell” processors replace the previous 22nm “Ivy Bridge” microarchitecture and are available for sale as of September 8, 2014. Note: these have since been superceded by Xeon E5-2600v4 Broadwell-EP Processors.

Important changes available in E5-2600v3 “Haswell-EP” include:

  • Up to 18 processor cores per socket (with options for 4-, 6-, 8-, 10-, 12-, 14- and 16-cores)
  • Support for DDR4 memory speeds up to 2133MHz
  • Advanced Vector Extensions version 2.0 (AVX2 instructions):
    • allow 256-bit wide operations for both integer and floating-point numbers (the older AVX instructions supported only floating-point operations)
    • introduce Fused Multiply Add FMA3 instructions, which allow a multiply and an accumulate instruction to be completed in a single cycle (potentially doubling throughput for floating-point applications – up to 16 FLOPS per cycle)
    • add support for additional instructions, including Gather and vector shift
  • Improved energy efficiency with Per Core P-States and independent uncore frequency control

With a product this complex, it’s very difficult to cover every aspect of the design. Here, we concentrate primarily on the performance of the processors for HPC applications.

Exceptional Computational Performance

The Xeon E5-2600v3 processors introduce the highest performance available to date in a socketed CPU. For the first time, a single CPU is capable of more than half a TeraFLOPS (500 GFLOPS). This is made possible through the use of AVX2 with FMA3 instructions. The plot below compares the peak performance of these CPUs with and without FMA instructions:

Plot of Xeon E5-2600v3 Theoretical Peak Performance (GFLOPS)

The colored bars indicate performance using only AVX instructions; the grey bars indicate theoretical peak performance when using AVX with FMA. Note that only a small set of codes will be capable of issuing almost exclusively FMA instructions (e.g., LINPACK). Most applications will issue a variety of instructions, which will result in lower than peak FLOPS. Expect the achieved performance for well-parallelized & optimized applications to fall between the grey and colored bars.

Intel Xeon E5-2600v3 Series Specifications

The tabs below compare the features and specifications of the new model line. Intel has divided the CPUs into several groups:

  • Standard: cost-effective CPUs with moderate performance
  • Advanced: CPUs offering the highest performance for most applications
  • High Core Count: ideal for well-parallelized applications; CPUs providing the highest number of processor cores (sometimes sacrificing clock frequency in favor of core count)
  • Frequency Optimized: ideal for non-parallel/single-threaded applications; CPUs with the highest clock speeds (sacrificing number of cores in order to provide the highest frequencies)

Although these processors introduce significant performance increases, technical readers will see that many of the changes are incremental: increased core counts, improved DDR memory speed, etc. However, processor clock speeds/frequencies have not seen significant improvements.

In fact, in some cases the CPU frequency has been lowered from the previous models. Processor frequency and Turbo Boost behavior have changed significantly with this release. Those metrics are discussed in further detail in the next section.

HPC groups do not typically choose Intel’s “Basic” and “Low Power” models – those skus are not shown.

Clock Speeds & Turbo Boost in Xeon E5-2600v3 series “Haswell” processors

With each new processor line, Intel introduces new architecture optimizations. The design of the “Haswell” architecture acknowledges that highly-parallel/vectorized applications place the highest load on the processor cores (requiring more power and thus generating more heat). While a CPU core is executing intensive vector tasks (AVX instructions), the clock speed may be reduced to keep the processor within its power limits (TDP).

In effect, this may result in the processor running at a lower frequency than the “base” clock speed advertised for each model. For that reason, each “Haswell” processor model is assigned two “base” frequencies:

  1. AVX mode: due to the higher power requirements of AVX instructions, clock speeds may be somewhat lower while executing AVX instructions *
  2. Non-AVX mode: while not executing AVX instructions, the processor will operate at what would traditionally be considered the “stock” frequency

* a CPU core will return to Non-AVX mode 1 millisecond after AVX instructions complete

AVX and Non-AVX Turbo Boost

Just as in previous architectures, “Haswell” CPUs include the Turbo Boost feature which causes each processor core to operate well above the “base” clock speed during most operations. The precise clock speed increase depends upon the number & intensity of tasks running on each CPU. With the “Haswell” architecture, Turbo Boost speed increases also depend upon the types of instructions (AVX vs. Non-AVX).

The two plots below show that processor clock speeds can be categorized as:

  1. All cores on the CPU actively running Non-AVX instructions
  2. All cores on the CPU actively running AVX instructions
  3. A single active core running Non-AVX instructions (all other cores on the CPU must be idle)
  4. A single active core running AVX instructions (all other cores on the CPU must be idle)

Clock Speeds for All-Core Operation

Diagram of Xeon E5-2600v3 CPU Frequency Speeds (comparing AVX and Non-AVX Instructions) running on all CPU cores

Clock Speeds for Single-Core Operation

Diagram of Xeon E5-2600v3 CPU Frequency Speeds (comparing AVX and Non-AVX Instructions) running on a single core

Note that despite the clear rules stated above, each value is still a range of clock speeds. Because workloads are so diverse, Intel is unable to guarantee one specific clock speed for AVX or Non-AVX instructions. Users are guaranteed that cores will run within a specific range, but each application will have to be benchmarked to determine which frequencies a CPU will operate at.

When examining the differences between AVX and Non-AVX instructions, notice that Non-AVX instructions typically result in no more than a 100MHz to 200MHz increase in the highest clock speed. However, AVX instructions may cause clock speeds to drop by 300MHz to 400MHz if they are particularly intensive.

Recall that AVX2 introduces support for both integer and floating-point instructions, which means any compute-intensive application will be using such instructions (if it has been properly designed and compiled). HPC users should expect their processors to be running in AVX mode most of the time.

Top Clock Speeds for Specific Core Counts

When workloads leave some CPU cores idle, the Xeon E5-2600v3 processors are able to use that headroom to increase the clock speed of the cores which are performing work. Just as with other Turbo Boost scenarios, the precise speed increase will depend upon the CPU model. It will also depend upon how many CPU cores are active.

We advise users to consider how many CPU cores their application is able to saturate. The tabs below detail the peak Turbo Boost frequencies for each CPU model, sorted by the number of active cores:

All of the above plots show CPU frequencies for applications utilizing AVX instructions. The colored bars indicate the worst-case scenario – CPUs will run at least this fast. The grey bars indicate the expected clock speeds for most workloads.

Cost-Effectiveness and Power Efficiency of Xeon E5-2600v3 CPUs

The “Haswell-EP” processors have nearly the same price structure and power requirements as earlier Xeon E5-2600 products, so their cost-effectiveness and power-efficiency should be quite attractive to HPC users. Savvy readers may find the following facts useful:

  • Although v3 Xeons follow the same price steps as their v2 counterparts, three High-Core-Count models were late additions. These models are higher performing and carry higher prices than previous E5-2600 models.
  • The power requirement (TDP) for each model has increased by 5 Watts over the previous generation. This is due to integration of the Voltage Regulator Modules (VRMs) which were previously placed on the motherboard. Thus, CPU TDP increases 5W and motherboard TDP decreases 5W.
  • The following graphs depict the cost-effectiveness and power-efficiency of only the CPU itself. In many cases, HPC users will find that once they’ve taken the full platform and cluster design into account, the cost-effectiveness of a higher core count CPU may be more beneficial than these plots demonstrate.

Summary of features in Xeon E5-2600v3 “Haswell-EP” processors

In addition to the capabilities mentioned at the top of this article, these processors include many of the successful features from earlier Xeon designs. The list below provides a summary of relevant technology features:

  • Up to 18 processor cores per socket (with options for 4-, 6-, 8-, 10-, 12-, 14- and 16-cores)
  • Support for Quad-channel ECC DDR4 memory speeds up to 2133MHz
  • Direct PCI-Express (generation 3.0) connections between each CPU and peripheral devices such as network adapters, GPUs and coprocessors (40 PCI-E lanes per socket)
  • Advanced Vector Extensions (AVX 2.0):
    • effectively double the throughput of integer and floating-point operations with math units expanded from 128-bits to 256-bits
    • introduce Fused Multiply Add (FMA3) instructions which allow a multiply and an accumulate instruction to be completed in a single cycle (effectively doubling the FLOPS/clock from 8 to 16 for each core of a CPU)
    • add support for additional instructions, including Gather and vector shift
    • F16C 16-bit Floating-Point conversion instructions accelerate data conversion between 16-bit and 32-bit floating point formats
  • Turbo Boost technology improves performance under peak loads by increasing processor clock speeds. With version 2.0, (introduced in “Sandy Bridge”) clock speeds are boosted more frequently, to higher speeds and for longer periods of time. With “Haswell”, top clock speeds depend upon the type of instructions (AVX vs. Non-AVX).
  • Dual Quick Path Interconnect (QPI) links between processor sockets improve communication speeds for multi-threaded applications
  • Improved energy efficiency with Per Core P-States and independent uncore frequency control
  • Intel Data Direct I/O Technology increases performance and reduces latency by allowing Intel ethernet controllers and adapters to talk directly with the processor cache
  • Advanced Encryption Standard New Instructions (AES-NI) accelerate encryption and decryption for fast, affordable data protection and security
  • 32-bit & 64-bit Intel Virtualization Technology (VT/VT-x) for Directed I/O (VT-d) and Connectivity (VT-c) deliver faster performance for core virtualization processes and provide built-in hardware support for I/O virtualization.
  • Intel APIC Virtualization (APICv) provides increased virtualization performance
  • Hyper-Threading technology allows two threads to “share” a processor core for improved resource usage. Although useful for some workloads, it is not recommended for HPC applications.

Xeon (ZEE-on) is a brand of x86microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded system 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, higher 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. 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 Quick Path Interconnect (QPI) bus.

Overview[edit]

The Xeon brand has been maintained over several generations of IA-32 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.

Some shortcomings that make Xeon processors unsuitable for most consumer-grade desktop PCs include lower clock rates at the same price point (since servers run more tasks in parallel than desktops, core counts are more important than clock rates), usually an absence of an integrated graphics processing unit (GPU), and lack of support for overclocking. Despite such disadvantages, Xeon processors have always had popularity among some desktop users (video editors and other power users), 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 GPU, systems built with those processors require a discrete graphics card or a separate GPU if computer monitor output is desired.[1]

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.

P6-based Xeon[edit]

Pentium II Xeon[edit]

Main article: List of Intel P6-based Xeon microprocessors § "Drake" (250 nm)

450 MHz Pentium II Xeon with 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 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 kB = 1024 B), 1 MB (1 MB = 1024 kB = 10242 B), 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).[2] 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]

Main article: List of Intel P6-based Xeon microprocessors § "Tanner" (250 nm)

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 for Tanner mirrored that of Katmai; 80525.

Main article: List of Intel P6-based Xeon microprocessors § "Cascades" (180 nm)

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 1Coppermine 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 for Cascades mirrored that of Coppermine; 80526.

Netburst-based Xeon[edit]

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

Foster[edit]

Main article: List of Intel NetBurst-based Xeon microprocessors § "Foster" (180 nm)

Main article: List of Intel NetBurst-based 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[clarification needed] 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[example needed]. Combined with the need to use expensive Rambus Dynamic RAM, the Foster's sales were somewhat unimpressive[example needed].

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]

Main article: List of Intel NetBurst-based 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.

"Gallatin"[edit]

Main article: List of Intel NetBurst-based Xeon microprocessors § "Gallatin" (130 nm)

Main article: List of Intel NetBurst-based Xeon microprocessors § "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 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

Main article: List of Intel NetBurst-based Xeon microprocessors § "Nocona" (90 nm)

Main article: List of Intel NetBurst-based 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 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 showed that AMD's Opteron still outperformed Irwindale. Both of these Prescott-derived Xeons have the product code 80546.

Cranford and Potomac[edit]

Main article: Pentium 4 § Prescott

Main article: List of Intel NetBurst-based Xeon microprocessors § "Cranford" (90 nm)

Main article: List of Intel NetBurst-based Xeon microprocessors § "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[edit]

"Paxville DP"[edit]

Main article: List of Intel NetBurst-based Xeon microprocessors § "Paxville DP" (90 nm)

The first dual-core CPU branded Xeon, codenamed Paxville DP, product code 80551, was released by Intel on October 10, 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.

7000-series "Paxville MP"[edit]

Main article: List of Intel NetBurst-based Xeon microprocessors § "Paxville MP" (90 nm)

An MP-capable version of Paxville DP, 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.

7100-series "Tulsa"[edit]

Main article: List of Intel NetBurst-based Xeon microprocessors § "Tulsa" (65 nm)

Released on August 29, 2006,[3] 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. It uses Socket 604.[4] Tulsa was released in two lines: the N-line uses a 667 MT/s FSB, and the M-line uses an 800 MT/s FSB. The N-line ranges from 2.5 GHz to 3.5 GHz (model numbers 7110N-7150N), and the M-line ranges from 2.6 GHz to 3.4 GHz (model numbers 7110M-7140M). L3 cache ranges from 4 MB to 16 MB across the models.[5]

5000-series "Dempsey"[edit]

Main article: List of Intel NetBurst-based Xeon microprocessors § "Dempsey" (65 nm)

On May 23, 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.

LV (ULV), "Sossaman"[edit]

Main article: List of Intel Pentium M (Yonah)-based Xeon microprocessors § "Sossaman" (65 nm)

On March 14, 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).[6] 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 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.

Jasper Forest is a Nehalem-based embedded processor with PCI Express connections on-die, core counts from 1 to 4 cores and power envelopes from 23 to 85 watts.[32]

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"[edit]

Main article: List of Intel Nehalem-based 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.[33] 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".[34]

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]

Main article: List of Intel Nehalem-based 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.

Sandy Bridge- and Ivy Bridge-based Xeon[edit]

E3-12xx-series "Sandy Bridge"[edit]

Main article: Sandy Bridge

Main article: List of Intel Sandy Bridge-based 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 and trusted 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.

E3-12xx v2-series "Ivy Bridge"[edit]

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 E3-12xx v3 is the first Xeon series based on the Haswell microarchitecture. It uses the new LGA 1150 socket, which was introduced with the desktop Core i5/i7 Haswell processors, incompatible 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 benefit of the new microarchitecture is better power efficiency.

Intel Xeon E5-1650 v3 CPU; its retail box contains no OEM heatsink

Introduced in September 2014, Xeon E5-16xx v3 and Xeon E5-26xx v3 series use the new LGA 2011-v3 socket, which is incompatible with the LGA 2011 socket used by earlier Xeon E5 and E5 v2 generations based on Sandy Bridge and Ivy Bridge microarchitectures. Some of the main benefits of this generation, compared to the previous one, are improved power efficiency, higher core counts, and bigger last level caches (LLCs). Following the already used nomenclature, Xeon E5-26xx v3 series allows dual-socket operation.

One of the new features of this generation is that Xeon E5 v3 models with more than 10 cores support cluster on die (COD) operation mode, allowing CPU's multiple columns of cores and LLC slices to be logically divided into what is presented as two non-uniform memory access (NUMA) CPUs to the operating system. 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.[37]

E7-48xx/88xx v3 series "Haswell-EX"[edit]

Main article: 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. Following the usual SKU nomenclature, Xeon E7-48xx v3 and E7-88xx v3 series allow multi-socket operation, supporting up to quad- and eight-socket configurations, respectively.[38][39] These processors use the LGA 2011 (R1) socket.[40]

Xeon E7-48xx v3 and E7-88xx v3 series contain a quad-channel integrated memory controller (IMC), supporting both DDR3 and DDR4 LRDIMM or RDIMM memory modules through the use of Jordan Creek (DDR3) or Jordan Creek 2 (DDR4) memory buffer chips. Both versions of the memory buffer chip connect to the processor using version 2.0 of the Intel Scalable Memory Interconnect (SMI) interface, while supporting lockstep memory layouts for improved reliability. Up to four memory buffer chips can be connected to a processor, with up to six DIMM slots supported per each memory buffer chip.[38][39]

Xeon E7-48xx v3 and E7-88xx v3 series also contain functional bug-free support for Transactional Synchronization Extensions (TSX), which was disabled via a microcode update in August 2014 for Haswell-E, Haswell-WS (E3-12xx v3) and Haswell-EP (E5-16xx/26xx v3) models, due to a bug that was discovered in the TSX implementation.[38][39][41][42][43][44]

She only moaned slightly to the beat of my movements. Her chest, spreading on both sides of her body, swayed in sync with my frictions like a badly frozen jelly. Her rather plump belly swayed in the same jelly-like manner. Lyuska and I have been married for fifteen years.

Or conversely, chat and make sure that she is not worth his torment. But every time I put my phone down. "Nothing, everything will be settled," he said to himself. - "Soon I will forget her!" Maybe some more time would have passed and Stas would have begun to forget Marina, if one day a. Miracle had not happened.
