Intel Xeon E5-2690 Sandy Bridge-EP Performance Leaked

We sourced a presentation, allegedly by Intel, detailing its Sandy Bridge-EP platform, and giving out early performance figures. After successful and trouble-free launches of its Sandy Bridge architecture across all PC form-factors, including the recently-launched Core i7 "Sandy Bridge-E" HEDT (high-end desktop), Intel is taking the architecture to its ultimate market, enterprise, where processors derived from it will make up new lines of Intel Xeon processor families. Intel has two branches of enterprise variations the architecture, Sandy Bridge-EN, designed for high-density, low-power servers, and Sandy Bridge-EP, designed for high-performance servers and workstations. Sandy Bridge-EP is multi-socket capable.

Sandy Bridge-EP uses essentially the same piece of silicon as Sandy Bridge-E, but enabled with several of its features otherwise off limits to the Core processor family. These include twoQuickPath Interconnect (QPI) links, which facilitate high-bandwidth inter-socket communication in multi-socket systems, up to eight cores, sixteen threads enabled by HyperThreading, and up to 20 MB of L3 cache memory. Like its Core family cousins, Xeon Sandy Bridge-EP packs a quad-channel DDR3 integrated memory controller, and PC3-12800 (DDR3-1600 MHz) is its optimal memory standard, but unlike it, supporting up to 768 GB of memory (by two sockets, eight DDR3 channels in all, LRDIMMs). Other key features are listed in the first slide below.
Performance figures follow.

Core i7-980 Released at US $583

As reported last week, Intel released its new Core i7-980 six-core processor to the retail channel. The new chip is priced at US $583 in 1000-unit tray quantities, displacing the Core i7-970 from this exact price point it previously held. It is expected that the i7-970 could eventually become cheaper while the platform is still in the market. The Core i7-980 is a socket LGA1366 six-core processor based on the 32 nm "Westmere" silicon. It is clocked at 3.33 GHz, with Turbo Boost speeds of up to 3.60 GHz. Unlike the Core i7-980X Extreme Edition, this chip has an upwards locked BClk multiplier, and its QPI link runs at 4.80 GT/s instead of 6.40 GT/s on the 980X Extreme Edition. As a trade off, the new chip is a little over half the price of the 980X Extreme Edition, which retailed for around US $999.

Intel Reveals New Logos and a Die Shot of Second Generation Core Processors

At the keynote of Intel Developer Forum 2010, the silicon giant gave a sneak-peak into its upcoming processor brand, revealing new product logos (case badges), and a die-shot of the Sandy Bridge quad-core silicon. Intel retains the Core i3, Core i5, and Core i7 brand identifiers, but refers to the family of processors based on the Sandy Bridge architecture as second-generation Core processors or the 2011 Intel Core processors. For the same reason, processor model numbers start with the 2000 series as detailed in this article.

The die shot reveals integration of the IGP-embedded northbridge component completely into the processor die. In "Clarkdale" Core i3 and Core i5 processors, the northbridge component was present on a separate die from the CPU die, with a QPI link connecting the two dies on the same package. The Sandy Bridge quad-core die is known to feature 6 MB of L3 cache, a dual-channel DDR3 IMC, and a DirectX 10.1 compliant graphics processor. Apart from merely driving graphics, the IGP also feature several media-acceleration features that speed up video encoding. Sandy Bridge is fabricated on the 32 nanometer HKMG process. The evolution of Intel's architectures is shown on the last picture. The "Nehalem" chip there is the Lynnfield quad-core processor that completely lacks an IGP, "Westmere" is the Clarkdale dual-core processor that has an IGP and memory controller on a second (larger) 45 nm die. The chip to the right is a 32 nm Sandy Bridge that integrates a quad-core chip with an IGP-embedded northbridge.

Intel to Introduce Core i7 960 in Q4

A lot of controversy and uncertainty is surrounding the future of lower end Core i7 models. Recently surfaced information suggested that the company would phase out lower models of Core i7 to make room for higher Core i5 ones. The recently introduced Core i7 950, is already staring at its successor, which will displace it from its price point, and put in in line for being phased out, as early as in Q4 2009.

The Core i7 960 inherits a part of its specifications from the Core i7 965 Extreme Edition, which is now replaced by the 975 Extreme Edition. The i7 960 comes with a clock speed of 3.20 GHz, with a bus multiplier of 24 (24 x 133 MHz). Unlike the 965 Extreme Edition chip, the multiplier will be capped at 24x, and it will use a 4.8 GT/s QPI interface, unlike 6.4 GT/s for the 965. The rest of its specs remain standard. It comes with a triple-channel DDR3 memory interface, and 8 MB of L3 cache. It is expected to be priced at US $562, displacing the Core i7 950 from its range.Source: TechConnect Magazine

Core i7 940 to be Phased Out

Intel's Core i7 has proven to be a fitting successor to Intel's higher-end Core 2 series processors, and is the fastest series of microprocessors the industry has to offer. Introduced in three variants: models 920 (2.66 GHz), 940 (2.93 GHz) and 965 XE (3.20 GHz), Intel targeted the sub-$300, sub-$600, and sub-$1100 segments. Due to the reasonably good overclocking potential the chips offer, 920 has been a successful variant due to its price, while 965 XE sold due to the sheer fact that it's a high-end chip with bus multipliers unlocked. The 940, however seems to have fallen in a tough spot, where buyers have to pay almost twice the price of 920 for a small increase in speeds.

To provide a better deal for the sub-$600 segment, Intel is in the works of phasing-out the Core i7 940. In its place, Intel will introduce the Core i7 950. This chip first surfaced in February. Its specifications include clock-speed increased to 3.06 GHz, while retaining the 4.8 GT/s QPI speed. This chip widens the gap between itself and the 920, providing the incentive of a significantly higher bus multiplier (23 x 133 MHz). An increased multiplier value will have its impact on the overclocking potential. As for 940, the company will continue taking orders from channel vendors till September 4th, in both tray and boxed forms, which will be delivered by November 5th and December 4th, respectively.Source: TechConnect Magazine

Core i5 to Feature Lower QPI Multiplier

Intel's newest line of CPUs, the Core i5 series is generating quite some buzz ahead of its release, with each piece of detail emerging about the processors adding to the attention it's gathering. Expreview has learned that the Core i5 series processors will feature a slightly different system interface in comparison to their Core i7 cousins.

Coming to the QPI interface between the CPU and NB dice, Intel will raise the QPI base frequency at the expense of lowering the multiplier. For example, the Core i7 uses a 20+ multiplier with a base frequency of 133 MHz. This frequency could be scaled up to 166 MHz at 24x multiplier due to the theoretical speed-limit of QPI at 8.00 GT/s. With the Core i5, Intel will set lower QPI multiplier values (around 16X), while upping the base frequency to around 250 MHz.
