Power Consumption

At idle, the 3960X's power consumption is barely discernible from the 2600K. Under load however, Sandy Bridge E can draw significantly more power. We measured 35% more power draw over a 2600K. The added power consumption makes sense. The chip has more cores and a larger cache, without introducing a more power efficient architecture or a new manufacturing process.

    "Quick Sync leverages the GPU's shader array"

    This is simply not true. And you know it. Shame.

    irrelevant CS4 test because someone buying this kind of hardware would appreciate the CS5 advantage other websites show.

    I was waiting for X79 but after I read the initial reviews I bought a Z68 motherboard and 2500K cpu for gaming.

    Me too. 999$+X79 for 0% improvement in gaming. What a crab! Bulludozer seems not that crab comparing to 3960x overall.

    Making unsubstantiated claims about something that is non-intuitive falls, in my dictionary, under fanboy-ism (if that's a word).
    The fact that Win7 "runs better" on a certain, relatively old, PC, is one thing. Stating that Windows7 is faster than XP (in spite of a documented benchmark proving otherwise) is another one.
    Like I said, you can compare OS in terms of HW support, ease of use, even responsiveness, however, neither of those translate into one OS beinf "faster".
    Faster means that when you run a benchmark (pick any of the ones that Anand run in this article), you get a noticeable increase in speed.
    The OSes provide the infrastructure to run applications, they cannot provide any fundamental speed difference, unless, of course, you have a PC without enough RAM, for example, and in that case the OS that uses less RAM will have an obvious advantage (because it offers more "free" RAM for apps to run), but that again, has nothing to do with one OS being faster: if anything, it is more efficient.
    I have 4GB on both my laptop (Win7) and on my desktop (WinXP) and the difference is negligible: I nearly always have more than 2GB of RAM committed, so it is no surprise that on your PC Win7 with ReadyBoost is faster: just spend ~$15 on 2GB of RAM and you'll see a huge performance improvement both on XP and 7.

    So "Faster" must not apply to the OS's capability to respond to the user, it must only apply to the OS's capability to server application requests?...

    Wait what?...

    You guys need to look at the engineering of your requests: 6 sata3 ports require feeding 6*6gb/s = 36 Gb/s data, while the total max theoretical mem bw of the chipset is 37 Gb/s. Can't do that while also taking care of OS, apps and video memory requirements.

    6*6gb/s isn't going to be happening constantly.....you build out one bridge that has a certain amount of bandwidth, 12GB perhaps, I don't know, and let the ports use the available shared bandwidth, doesn't mean you can't add additional ports, this is one of the benefits of serial interfaces.

    Intel Gulftown 6C 32nm 6 1.17B 240mm2
    Intel Sandy Bridge E (6C) 32nm 6 2.27B 435mm2

    SB-E, What a crab! Double Transistors, Double size, merely 20% gain from SB 2600k. 999$ for this? I would rather get 2 pcs Interlagos 6200 instead.

    using 5870 CF to show us that dual 8x PCIE are same as dula 16x is a mistake I am shocked some one like you fall in ...

    you should have tested 6990 in CF , or 590 ... and see the difference between 16x SLI/CF and 8x SLI/CF

    and how do you consider a 5870 a MODERN GPU ?

    Quote : "Modern GPUs don't lose much performance in games, even at high quality settings, when going from a x16 to a x8 slot."

    Answer : WRONG . try high end dual GPU cards in SLI/CF !
