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.

Well the dilemma for Anand is apparent. If he stops writing those previews that is nice to Intel, someone else will get the oportunity and all the info. He can write two bad previews and the info and early chips just stops comming. Intel and Anand have a business to run, and there is a reason Intel gives Anand the chips (indirectly).He have a "deal" with Intel, the same way we have a deal with Anand when we read the review. We get the info - bended/biased - and then we can think ourselves. I think its a fair deal :) - we get a lot of good info from this preview. The uninformed gets raped, but its alway like that. Someone have to pay for the show.

The Macbook Pro, for instance, has a discrete GPU, yet can switch to the chip-based GPU to save power when on battery. So having a better chip-based GPU makes sense in this context.Sabresiberian - Wednesday, March 7, 2012 - link
I'd like to see the discreet graphics card industry make the kind of progress, relatively speaking, Intel has made in the last 2 years.Ivy Bridge is a ways from competing with a high-end discreet solution, but if the relative rates in progress don't change, Intel will catch up soon.

I use the iGPU on my build for my second monitor and it is quite nice.I can watch HD videos on it and it doesn't take away from my dedicated GPU at all.

Is that even possible? Special hack or software?When you install a discrete graphics card, the integrated gpu gets disabled.
Would love to know how you accomplished this..Is it a desktop or laptop?

"When you install a discrete graphics card, the integrated gpu gets disabled."It was exclusive in northbridge-IGP units (Core2Duo/Quad and older). With Core-i, it's by default disabled but can be enabled through BIOS (of course if you don't have a P5x/6x chipset).

1. How much faster is Ivy Bridge at single thread versus my Conroe@3GHz?2. How much faster is my GTX560Ti than HD4000?

1) Your 65 nm cpu would get the shit blow out of it by IB at the same clock speed in single threaded applications. Assuming 15% improvements in each of the tick-tocks since Conroe, a 1.8 Ghz IB would probably be about the same as a 3 Ghz Conroe.2) Discrete graphics vs. integrated graphics. Intel isn't trying to compete here so it's a stupid comparison.

1. Your "get the shit blown out" is worthless. All I'm looking for is a number, and your effective answer is +67%.2. It's not a stupid comparison, because:
a) I'm interested.
b) HD4000 is designed for games.
c) They benchmarked with modern games.
d) Games are designed around people's performance.

1. Another website shows the i7 3770K scored 2643 on the Fritz Chess Benchmark with 1 processor. My machine does 2093. That's only 26% different.2. I very roughly estimate the GTX560Ti might be 5-6x faster than the HD4000.
It'd be useful to see a real comparison of these though.
