Metro 2033
The heaviest test we'll show in this suite, Metro 2033 still requires a discrete GPU for reasonable performance. That being said, it's still an interesting measure of how much more GPU horsepower exists in Ivy Bridge:
Here the Llano gap shrinks to about 13 - 25% depending on the resolution/quality settings. AMD still has the clear advantage in GPU performance, but Intel does step closer. The performance advantage over Sandy Bridge ranges from 20 - 40%. With these sorts of numbers it's clear why Intel views Ivy Bridge as being a tick+. Generational performance improvements on the CPU side generally fall in the 20 - 40% range. As you've just seen, Ivy Bridge offers a 7 - 15% increase in CPU performance over Sandy Bridge - making it a bonafide tick from a CPU perspective. The 20 - 40% increase on the graphics side is what blurs the line between a conventional tick and what we have with Ivy Bridge.

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.
