Anisotropic Filtering Quality
At IDF last year Intel promised an improvement in its anisotropic filtering quality compared to Sandy Bridge. Personally I didn't believe SNB's GPU was fast enough to warrant turning on AF in most modern titles, but as Intel's GPU performance improves it must take image quality more seriously.
I wouldn't put a ton of faith in these early results as things can change, but AF quality does appear to be much better than Sandy Bridge:
The peculiar radial lines that were present in SNB's algorithm remain here, although they are more muted. Again it's too early to tell if we're looking at final image quality or something that will improve over time. If we are to judge based on this result alone, I'd say it mirrors what we saw in our performance investigation: Ivy is a step towards AMD in the GPU department, but not a step ahead.
DirectX 11 Compute Performance
As Ivy Bridge is Intel's first DirectX 11 GPU architecture, we're actually able to run some DX11 workloads on it without having them fall back to DX10. We'll do a much more significant investigation into GPU compute performance in our full Ivy Bridge review, but as a teaser we've got our standard DirectX 11 Compute Shader Fluid Simulation test from the DX11 SDK:
Ivy Bridge does extremely well here, likely due in no small part to its excellent last level cache. The Fluid Simulation we run looks at shared memory performance, which allows Ivy to do quite well. We're seeing over 3.2x the performance of Sandy Bridge here, and even a slight advantage over Llano.

I think it's a long time away from approaching 560m performance. If you're going to do any remotely serious gaming on a laptop it's still best to get a dedicated graphics card.I'm still sticking to gaming on a tower, so these CPUs (esp the AMD llano) make sense for me in laptops. Don't ever see myself gaming on a laptop unless I completely get rid of the towers in my house... which won't happen anytime soon (if ever.)

I felt the same way when I was shopping recently. I WANTED to buy a Llano-based notebook (inexpensive, better graphics vs. Intel). The problem is there's no such thing as a slim and light Llano. Every OEM sticks you with the same configuration: six pounds and 15.6" turd-768 resolution screen. It's bizarre.For the sake of competition, I hope Trinity will get some better design wins.

If you look at the gaming charts, the resolution may go past x768, but the settings are on LOW, and don't give us a minimum frame rate, so the answer is:That's all that llano can handle is low end low rez.
So AMD forces the giant .lb weighted monster as a selling point.

so AMD?Demon-Xanth - Wednesday, March 7, 2012 - link
I agree with you there. To get those "$100 mid range GPUs" on a laptop you need to bump up the cost by around $400 to get to one that simply can have one. Most laptops currently do not have discrete GPUs.I am glad to see that integrated graphics from both Intel and AMD can now be compared with low end cards like the GT520 and GT440 without it becoming a laugh. Also that they are actually completing the tests well now. That is a rather major step. I remember some reviews of integrated graphics that resulted in a lot of either "could not complete" or "the bar is too small to fit a number on" entries.

The IGP provides the QuickSync implementation. It would be insane to not include the silicon for it on the high end system. In addition moving forward you can get compute work out of the GPU so why would you ever not include it.danjw - Wednesday, March 7, 2012 - link
Quicksync the Intel video transcoding feature is based in the GPU. This is important to a lot of users.sweetspot - Wednesday, March 7, 2012 - link
Well also these make for nice office machines. So businesses upgrading there desktop workstations.When you have thousands of employees, the desktop refresh, these are decent option, since they are not gaming at work ( right lol ).

Hardly any large corporations buy desktops anymore. Maybe for the call centre employees, that's about it.AFUMCBill - Wednesday, March 7, 2012 - link
Because gaming isn't the only thing that uses graphics cards. For instance, more and more video editors use the graphics card for doing video decode/encode/applying effects. So having a high performance graphics engine to go along with the high performance CPU can be a really nice thing.
