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.

It would have been interesting to see. Personally, I don't care for IGP, as they sit disabled anyway. Right now, it seems like it's a 7% clock for clock perf increase, which is very poor for one process node. Knowing where the clocks can be will let everyone know exactly how much faster the CPU can be over SB.NeBlackCat - Wednesday, March 7, 2012 - link
For me, the most interesting things about IVB are improved multi-monitor support, and power savings not just at stock, but also undervolted (stock clock) and overclocked.Because I want to know if I'm finally going to get that laptop or mini-itx system that can drive several monitors while remaining cool and sipping power, even under load.
Not covered at all. Shame.

Intel marches on. Their domination of 80+% of all CPU markets will continue.silverblue - Wednesday, March 7, 2012 - link
PC and especially server market, sure, but not smartphone/tablet. Not yet, anyway.fvbounty - Wednesday, March 7, 2012 - link
Should have a had SB 2700K to run clock for clock against the 3770K and see if there's much difference!ellarpc - Wednesday, March 7, 2012 - link
Agreed! I was just about to post that same comment. It doesn't make much sense to compare it to a lower clocked SB product. Well unless you wanted to make the IB look better. Now I'm going to sift through anand's past reviews to see what kind of gains the 2700 has over the 2600.ellarpc - Wednesday, March 7, 2012 - link
Doesn't look like Anand has a 2700k for testingueharaf - Wednesday, March 7, 2012 - link
I was thinking that the difference in gpu perfomance between HD3000 and HD4000 about 20% to 40% increase perfomance, will remain in the ivy-bridge mobile chips!!! I hope soo!!!lilmoe - Wednesday, March 7, 2012 - link
Great review. You guys know your stuff. I've been waiting for a review like this since IvyBridge was announced.However, I'll still "cling to my Core 2" since it does the job now, and I'll postpone my upgrade till next year. You make it seem like Haswell is a good reason to wait. I bought the system in early 2010, and I usually upgrade every 2-4 years. 3 years sounds just right. I'll be investing in SSDs since you talked me into it though, it seems a better upgrade at the moment.

Did Intel specifically ask not to include overclocking tests in ES previews?
