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.

Until AMD goes out of business. Then Intel gets lazy again, and the price of even a mid range CPU creeps back up above 600 dollars. You might be too young to remember the 500 dollar price tags on the first gen P3s, when Intel had no effective competition from AMD.Its not in the consumer's best interests for AMD to die off.
And, FYI, their GPUs are top notch and excellent, across the entire market. Downside is, they're basically carrying the company right now and that's not sustainable.

This sans guy is hilarious!!Lets prod him a bit more and really get his fanboi juices flowing :)
AMD is the best!!!!! yaaay....Intel sucks they'll go out of business sometime next week :D

it doesn't really matter if the igp isn't that great most people don't buy them for their graphics power.I get the feeling that maybe intel is just putting them out there to keep it's base solid against AMD,Not that it needs it and i'm an amd fan. i found something the other day that will possibly change how tomorrows processors will use light instead of electricity.http://scitechdaily.com/penn-researchers-build-a-c...

it would be cool to see a 4ghz clocked nehalem shuffled in the mix. I'm sure I'm not the only one rocking an i7 9xx wondering how much actual productivity gains are to be had with the new tech. I personally don't like to upgrade until the new gen's retail performance out-does my previous overclocked performance by a solid 15%.svata - Wednesday, March 7, 2012 - link
Is the bug with true 23.976 fps playback fixed?http://www.anandtech.com/show/4083/the-sandy-bridg...

I understand that will be part of the new chipsets which haven't been tested here, but I'm also very interested. As a matter of fact, I have a few HTPC customers waiting for Ivy Bridge for this sole reason.vlado08 - Friday, March 9, 2012 - link
I don't find the silence about 23.976 fps playback very promising. This is new chipset "Keep in mind that this is a preview using early drivers and an early Z77 motherboard" .... "Intel Z77 Chipset Based Motherboard"I find three possibilities:
1. They are not going to fix it with Ivy bridge.
2. They are not ready with the drivers.
3. They are ready and everything is fine but keeping silen becoause they need to sell old chips.
It didn't left much. We'll see.

Intel's always the best, EXCEPT WHEN THEY'RE NOT! Athlon 64. Since AMD's sticking with Bulldozer's base architecture for at least a couple generations, they won't be competitive for a while, but that doesn't mean they'll never be competitive.
