Intel Xeon E5-2690 Sandy Bridge-EP Performance Revealed

Intel is taking its newly launched Core i7 Sandy Bridge-E platform to the enterprise market with a new line of Xeon processors. Intel's new enterprise variations include the Sandy Bridge-EN and Sandy Bridge-EP. The Sandy Bridge-EN is designed for high-density, low-power servers, while the Sandy Bridge-EP is designed for high-performance servers and workstations. The Sandy Bridge-EP is multi-socket capable platform.

The Sandy Bridge-EP appears to be basically the same design as the Sandy Bridge-E, but has several additional features not found with the Core processors. The Sandy Bridge-EP offers two QuickPath Interconnect (QPI) links, which utilize QPI 8.0 GT/s. This will help 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. Sandy Bridge-EP will utilize a quad-channel DDR3 integrated memory controller (DDR3-1600 MHz) with support up to 768 GB of memory, via two sockets, eight DDR3 channels in all, LRDIMMs. In addition, Intel Integrated I/O has support for up to 80 lanes of PCIe 3.0.

Intel claims up to 80 percent performance boost versus its prior generation Westmere-EP platform. Using a Xeon X5690 six-core processor (@ 3.64 GHz) as the baseline, Intel put its new Xeon E5-2690 eight-core processor (@ 2.90 GHz) to the test. Performance results showed an improvement across the board on all testing; OLTP Database (TPC-C Oracle), Middle-Tier Java (SPECjbb 2005), Integer Throughput (SPECint_base2006), Floating Point Throughput (SPECfp_rate_base2006), Memory Bandwidth (STREAM_MP Triad), and Matrix Multiplication (Linpack).

Intel provided details on its new Data Direct I/O Technology (DDIO). DDIO works to increase I/O performance by up to 2.3 times that of previous generation, reduces latency and allows system memory to remain in low power state.

    I honestly feel bad whenever I read Intel "leaks" and comparisons for their upcoming chips since they almost always deliver on the promise and hype,.

    AMD so far never get past the hype with its Bulldozer,. a repeat performance from their Piledriver should essentially seal off AMD from the x86 market.

    To AMD,. please give us the same joy with the release of Athlon 64,.
    Alot probably gave up on you,. but there's always a second chance..

    I'm excited to see benchmarks/comparisons to latest Opterons and their own Westmere Xeons.

    Personally, I like the look of that SB-EN chip. It's not as overblown as the SB-E: 3 memory channels, 8 cores, 20MB cache, 24 PCIe3 lanes (3 x8 slots would be nice for 3 way SLi without overdoing it, maybe using a bridge chip to change those to x16 PCIe2), and a single QPI link. It's meant for single socket designs. We already know the quad channel memory config doesn't help anything. Triple channel memory would be fine. (Works fine for my 920.) I just hope it's not too overpriced.
