Video Transcoding Performance
x264 HD 3.03 Benchmark
Graysky's x264 HD test uses x264 to encode a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
In the second pass of our x264 test we see a nearly 14% increase over the 2600K. Once again, there's no replacement for more cores in these types of workloads but delivering better performance in a lower TDP than last year's quad-core is great for more thermally conscious desktops.
Software Development Performance
Compile Chromium Test
You guys asked for it and finally I have something I feel is a good software build test. Using Visual Studio 2008 I'm compiling Chromium. It's a pretty huge project that takes over forty minutes to compile from the command line on a Core i3 2100. But the results are repeatable and the compile process will stress all 12 threads at 100% for almost the entire time on a 980X so it works for me.
Ivy Bridge shows more traditional gains in our VS2008 benchmark - performance moves forward here by a few percent, but nothing significant. We are seeing a bit of a compressed dynamic range here for this particular compiler workload, it's quite possible that other bottlenecks are beginning to creep in as we get even faster microarchitectures.

How long will Intel keep its HD Graphics increases?MonkeyPaw - Tuesday, March 6, 2012 - link
I don't understand the logic of selling a high end CPU with the best IGP. Seems like anyone running an it isn't going to stick with the IGP for games, and if they aren't gaming, then what good is that high-end GPU? Maybe the entire "Core i" line should use the HD 4000.Flunk - Tuesday, March 6, 2012 - link
Because the low end chips are just die-harvested high end chips it makes sense. No reason to disable it so they leave it on.And some people do actually use high end processors with IGPs. It's fairly easy to get one from a major OEM. It's stupid but most people don't know any better.

Funny comments I saw.What's wrong even if the High End CPU that comes with IGP?
Is High End CPU = Gaming Machine CPU? If that is your logic, you're a rich but shallow boy!
I do lots of Video Editing and Transcoding, I need High End CPU but None of the High End GPU beats Quick Sync in Transcoding in terms of Quality and Speed.

"and if they aren't gaming, then what good is that high-end GPU?"I feel like you missed that part. He's not saying that only gamers use high-end CPUs. He's saying that gamers using a high-end CPU won't care about the high-end iGPU because they won't use it. Also, non-gamers who need a high-end CPU generally won't see the benefits of the included high-end iGPU. So, he proposes that the better niche for the high-end iGPU would be on the more affordable CPUs, because then budget-minded gamers could buy an affordable CPU that has a relatively powerful iGPU integrated into it.

This is a mid-range CPU, not high-end one.High desktop CPUs (i7 3800-3900) don't have IGP.

It is because laptops continue to get slimmer and slimmer. Getting good GPU performance without the compromises on the chassis that a dedicated GPU would force is the point.Tormeh - Wednesday, March 7, 2012 - link
This.My next laptop will have processor graphics for the sake of battery life and size, and whoever has the best graphics gets my money.

If the 4000HD is on the level of lets say a 560m I would not hesitate to get a laptop with no dedicated graphics but if it isn't I'm still going to go for the dedicated.
