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.

"There's not enough of an improvement to make existing SNB owners want to upgrade, but if you're still clinging to an old Core 2 (or earlier) system, Ivy will be a great step forward."Basically all the laptops in the last few years for business have been bought with C2D. I think with Ivy, it's a great time to upgrade them all and see a good improvement. Same for family members too. I can't wait to try them out! Thanks for the review Anand.

maybe intel should drop the graphics all together, i don't like it, let the pro take care of it. just too much.dr/owned - Thursday, March 8, 2012 - link
This article blows because there's no overclocking results. We're not looking for a fine tuned overclock. Just give us the rough and dirty! My money is on 5 ghz with minimal effort using an air cooler.dagamer34 - Thursday, March 8, 2012 - link

It seems like Intel has the tick-tocks backwards. The i7-920 is arguably the greatest cpu to come out in recent years and it was "just" a tick.Wardrop - Thursday, March 8, 2012 - link
I'm afraid you have it backwards.The i7-920 is a Nehalem processor (it's a 45nm chip). It's a tock. Why is this concept so hard to grasp?

Look at the chart. Nehalem (i920) was a tock.just4U - Thursday, March 8, 2012 - link
I have to disagree with you on the i920 being such a huge leap. As someone who goes thru virtually every cpu line up for AMD/Intel I'd have to say the C2D (or quad) 6x series was the biggest leap forward in the past decade. Before that it was the A64 and X2 variants (altho.. we didn't get alot of use out of those secondary cores)IntelUser2000 - Thursday, March 8, 2012 - link
LOL, this must be the most hilarious argument I've heard in a while.How do you relate 30+ % graphics gain as being ALL CPU? Don't be ridiculous, and that's an understatement.

Are low-res testing really relevant for graphics?Most players play at 1920x1080 or higher.
1368x720 or 1680x1050 does not seem relevant to me at all for most people, especially those purchasing a computer with this processor.
