QuickSync Performance
Late last year we mentioned that Intel would be bringing improved QuickSync to Ivy Bridge. Details were scarce, but we theorized that improvements to Ivy Bridge's video decoder might be part of the reason. At least with the drivers we tested with, improved video decoder speed was largely responsible for the advantage you can see below.
For this test we transcoded a 3GB AVC main profile movie using ArcSoft's 720p 3Mbps YouTube HD profile:
Once again we're showing a ~40% improvement over Sandy Bridge - a big step forward. The QuickSync side of IVB is one of the lesser known aspects of the architecture, I suspect we'll have to wait for the launch to truly understand what we can expect from Ivy. Needless to say, QuickSync is even faster this year.

CPU perf pretty much as expected,GPU perf somewhat dissapointing ,i thought they'll at least aim to match Llano but i guess it is ok for 1MP laptops screens if mobile parts perform close enough (and a couple of big ifs when it comes to image quality and drivers).Any opinions yet about QuickSync encoding quality?

And we should remark that's comparing 2600 with 3700 which have different cpu too.Other benchmarks had significantly better results on 3700 than 2600.
So Anand, how you know that difference is not attributable to the CPU and not to some gpu improvement?

You are not being serious, are you? The CPU gets 10% in CPU sensitive benchmarks and GPU gained 40-60%. Even taking out 10%, its still 30-50%, which btw isn't true as games aren't very sensitive to CPU changes as applications do.wifiwolf - Wednesday, March 7, 2012 - link
Look at crisys or metro benchmarks and tell me where you find that improvement, at least more than what you find in cpu difference.mosu - Wednesday, March 7, 2012 - link
I've tried it on some HD clips at a local TV station and on a big screen it really sucked.It's way behind AMD.We used aHP EliteBook 8460P laptop.Articuno - Tuesday, March 6, 2012 - link
At least AMD's products are HD capable.dr/owned - Thursday, March 8, 2012 - link
My 5 year old laptop with a shared ram gpu is "HD capable". GTFO noob.Articuno - Tuesday, March 6, 2012 - link
Billions in R&D, double the MSRP, half the power and yet it still can't play Crysis better than Llano, which will be replaced by Trinity in a few weeks. What a crying shame.travbrad - Tuesday, March 20, 2012 - link
Not playing Crysis sounds like a good thing to me.tipoo - Tuesday, March 6, 2012 - link
Source or gtfo. Apple got the stock HD 3000, why would this be different?
