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.

    nevermind, I'm an idiot. I found it. Reply

    Keep in mind that in Ivy Bridge, CPU speed is directly propotional to GPU's speed + performance.

    In the mobile line up, there is only 1 SKU for Intel Processors. As they cut back on the CPU, the HD3000 or HD4000 remains for ALL mobile GPUs. Reply

    I just got a 3450, the tag on it says 95w, your chart here says 77w. I'm a little worried i just got a repackaged SB cpu.... Reply

    For those who want to see a comparison of 3770K to 2600k in more games (several sites), please check the article:

    "Quick Sync's transcoding abilities are limited to applications like Media Espresso or ArcSoft's Media Converter—there's still no support in open source applications like Handbrake."

    Umm, try MediaCoder, steep learning curve but it works great! I also wish Handbrake would adopt this technology...

    I would like to say that they do not seem to say what they are running for GPU, also I own the fx chip in this review and would like to say that with the 7970 driect cuII asua vide card, I get way over those FPS in dawn of war maxed out gfxs I am getting 134 average fps

    I also own dragonage and when I am running fraps I am getting maxed res max AA getting 139 average fps

    cyris I get 139 fps and I get civ 5 225 fps

    be honest the cpu has little to do with FPS its video card mostly anyways I am running eyeinfity setup on top of this and getting these fps in game according to fraps

    I have the AMD FX 8150 and I also own Crysis: Warhead, Civilization V, Dawn of War II, and Dragon Age Origins and I get way better FPS then they claimed to have gotten I mean my FPS are almsot double that, sometimes tripple and I am using Farps

    for exampel Civ 5 I get average of 190 FPS in game maxed out res with eyeinfity using Fraps

    but I am also using a 7970 Directcu2 GPU

    double post, I almost did same thing lol, becuase I noticed my post was tooken down or did not show up right away..

    I have to agree with you I own your CPU also, one they dont claim to be using on board GPU meaning one built into CPU and if they where far as I know teh AMD fx dosnt have a built in GPU so it would suck and there actully called APU i belive ?

    anyway I was also wondering what GPU they where using for the test becuase when I read this page it dosnt say it any where and page before the two buttons say review back and review http://www.anandtech.com/show/5771/the-intel-ivy-b... dosnt say anything about what GPU there using, but I do own amd FX and I also own a 7970 GPU and I will say that the FPS ratting on here a AMD FX comboed with 7970 you will get ammzing FPS in game it blows these fps they claim out of the water, the FPS 50 FPS I mean I use to get that with my 5k series amd card I hell I use to get 45 to 50 fps with my 6k series eyeinfity card this 7970 gets like use above says double or tripple preformance of whats claimed in this review with fraps.
