Intel HD 4000 Explored
What makes Ivy Bridge different from your average tick in Intel's cycle is the improvement to the on-die GPU. Intel's HD 4000, the new high-end offering, is now equipped with 16 EUs up from 12 in Sandy Bridge (soon to be 40 in Haswell). Intel's HD 2500 is the replacement to the old HD 2000 and it retains the same number of EUs (6). Efficiency is up at the EU level as Ivy Bridge is able to dual-issue more instruction combinations than its predecessor. There are a number of other enhancements that we've already detailed in our architecture piece, but a quick summary is below:
— DirectX 11 Support
— More execution units (16 vs 12) for GT2 graphics (Intel HD 4000)
— 2x MADs per clock
— EU can now co-issue more operations
— GPU specific on-die L3 cache
— Faster QuickSync performance
— Lower power due to 22nm
Although OpenCL is supported by the HD 4000, Intel has not yet delivered an OpenCL ICD so we cannot test functionality and performance. Update: OpenCL is supported in the launch driver, we are looking into why OpenCL-Z thought otherwise. DirectX 11 is alive and well however:
Image quality is actually quite good, although there are a few areas where Intel falls behind the competition. I don't believe Ivy Bridge's GPU performance is high enough yet where we can start nitpicking image quality but Intel isn't too far away from being there.
Current state of AF in IVB
Anisotropic filtering quality is much improved compared to Sandy Bridge. There's a low precision issue in DirectX 9 currently which results in the imperfect image above, that has already been fixed in a later driver revision awaiting validation. The issue also doesn't exist under DX10/DX11.
IVB with improved DX9 AF driver
Game compatibility is also quite good, not perfect but still on the right path for Intel. It's also worth noting that Intel has been extremely responsive in finding and eliminating bugs whenever we pointed at them in their drivers. One problem Intel does currently struggle with is game developers specifically targeting Intel graphics and treating the GPU as a lower class citizen. I suspect this issue will eventually resolve itself as Intel works to improve the perception of its graphics in the market, but until then Intel will have to suffer a bit.

nevermind, I'm an idiot. I found it.PG - Sunday, April 29, 2012 - link

Keep in mind that in Ivy Bridge, CPU speed is directly propotional to GPU's speed + performance.Source - http://mobilityupdate.com/notebooks/intel-hd-4000-...

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.SalientKing - Tuesday, May 8, 2012 - link
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....warmbit - Wednesday, May 9, 2012 - link
For those who want to see a comparison of 3770K to 2600k in more games (several sites), please check the article:http://translate.google.com/translate?hl=pl&sl...

"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 fpsI 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 Farpsfor 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.
