Power Consumption

Intel isn't really exploiting 22nm for significantly higher default or max turbo frequencies. While it does seem like you'll hit turbo frequencies more often with Ivy, most of what 22nm offers will be realized as power savings.

The data in the charts below is from our original 3770K preview, however I've also provided a table comparing the 3770K to the 2700K using Intel's own Z77 motherboard which is a bit more power hungry than our typical testbed:

Power Consumption Comparison
Intel DZ77GA-70K Idle Load (x264 2nd pass)
Intel Core i7 3770K 80.1W 146.4W
Intel Core i7 2700K 79.4W 177.6W

As you can see, there are no savings at idle and a reasonably significant improvement under load.

The same is echoed on our earlier chip in a more power efficient platform:

Power Consumption—Idle

Power Consumption—Load (x264 HD 3.03 2nd Pass)

I was also curious to see what power consumption would look like compared to other low-end GPUs. For these next results I used the 3770K alone, without a discrete card and measured power consumption. I then added in discrete GPUs from our HD 4000 comparisons and looked at both idle and load power while playing Metro 2033:

GPU Power Consumption—Idle

Obviously at idle it's impossible to beat the HD 4000, the GPU is largely stopped/gated when idle keeping power consumption to a minimum. Under load is where things get interesting:

GPU Power Consumption—Load (Metro 2033)

Ivy's GPU is much more power efficient than SNB's, however Intel still has a way to go before it starts to equal the power efficiency of modern discrete GPU architectures. Remember the HD 4000 is on Intel's 22nm process here while the GT 440 is built on TSMC's 40nm process.

    I was thinking the exact same thing.

    I waited long to jump on the dual core bandwagon, 2008 with a C2D 8400. I havent jumped on the quad core wagon yet. Was waiting for them to run cooler.

    This seems like a good time to make the jump.

    I'm going to get rid of my 2500K @ 4.8GHz , because it's HD3000 just isn't doing it for BF3,

    and I'm going Trinity man !

    See me and my amd apu on the gaming servers !

    a. totally wanna be cool amd fan
    b. fantasy boy with lunch money from mommie in pocket
    c. bonkers
    d. all the above

    Yea, but WHEN can I buy one? Forgive me if I missed that all important detail. My desktop is 2.5 yrs old and am ready to upgrade here. Show me where to buy, lol. Reply

    OEM boxes arrive April 29th. I expect NewEgg will have parts shortly thereafter. Reply

    +1

    I thought the April 23 launch date meant that was when we would be able to buy one.

    Why no benchmarks against a 2700K, you know - a real platform comparison? I'm guessing it's exactly the same performance? Reply

    Working on testing the 2700K now - didn't have one at the time that the CPU tests were conducted, the difference is small as you can guess, will add results to bench as they are completed.

    Take care,
    Anand

    ...but really, they already have large quantities of benchmarks of the 2600K and the difference between that and 2700K is going to be relatively meaningless...my guess, not worth the trouble of running the whole suite of benchmarks on it. To my knowledge, the only difference is 100 MHz of clock speed, right? Reply

    Any chance Anand that we get a 35W Quad Core processor for laptops like the Macbook Pro 13" Reply

    There is i7-3612QM which is a 35W 2.1GHz quad core. Whether Apple uses it is another question, though.
