"Intel has announced the latest revision to it's Enterprise CPU range. The Xeon E7 v2 is based on Ivy Bridge rather than the aging Westmere, and specifically targets the Big Data Analytics market. In pursuit of this they've bumped up the core count to 15, reduced power consumption, reworked the cache, and included a long list of smaller improvements. The end result is a high-reliability chip that uses less power but has dramatically improved performance for most workloads.

A single-page version of the article is available here."

        overclocking and overbussing is very old.

        the new hotness is overcoring.

        hitting control-alt-shift-tab-backslash can turn on that extra cpu (if you have the right kernel patch).

      Something says they put 16 on, but expect one to be flawed, so do testing until they find the weak one, and disable it. (Nothing new about that, the old 486SXs were just DX's which had failed FPU tests, and had them disabled by e-fuse. I think AMD did some 3-core chips more recently which were 4-cores with the duff one disabled.)

          My SX25 fell by the wayside when I tried to get Windows 95 installed on it. Had to compress the hard drive too, as it was only 170MB. Replaced it with a DX4-100 then my first homebuilt PC - a P2-300

          When I buy servers now, I tend to spec low cores high CPU - x264 encoding is the only thing that really taxes what are in effect nas drives, currently that would be a single E5-2637 V2. 4 cores, 3.5GHz [intel.com]

          However most servers serve multiple people, and run multiple threads, and can make use of wide processors. My favoured vendor suggests putting some 12-core processors in. Even on the storage chasis I go for, with two physical processors, that's 24 cores, it's a phenominally wide system. I do wonder how many systems can make use of that number of cores, but can't be easilly parallelised onto multiple cheaper machines. 6x4 core machines are in most cases going to be cheaper than a 24 core machine.

        Assuming the image in TFA [hothardware.com] is actually correct, the chip seems to have exactly 15 cores, arranged in 3 columns of 5 cores.

        You're of course right that manufacturers sell partially-functional chips at lower cost. So we will probably see cheaper versions of this chip (e.g. with only 12 of the cores enabled).

        and when it comes to transistors, "all your base are belong to us".

        you are free to use collectors and emitters as you see fit, though.

      15 allows a 3x5 layout, so it's not too bad from an architectural perspective. It's also quite nice for addressing, because you can use a 4-bit core address with a broadcast address for cache coherency messaging.

      The cores are more or less equal to each other and attached to a high speed ring bus which is also their interface to the L3 cache and beyond.

    I can't tell from the article - do all 15 core have their own FPU or did they copy AMD and share FPUs between multiple cores? That's great for databases but not so good for HPC, but then again many HPC systems will have GPUs for hardcore math.
