Discrete GPU Gaming Performance
Gaming performance with a discrete GPU does improve in line with the rest of what we've seen thus far from Ivy Bridge. It's definitely a step ahead of Sandy Bridge, but not enough to warrant an upgrade in most cases. If you haven't already made the jump to Sandy Bridge however, the upgrade will do you well.
Dragon Age Origins
DAO has been a staple of our CPU gaming benchmarks for some time now. The third/first person RPG is well threaded and is influenced both by CPU and GPU performance. Our benchmark is a FRAPS runthrough of our character through a castle.
Dawn of War II
Dawn of War II is an RTS title that ships with a built in performance test. I ran at Ultra quality settings at 1680 x 1050:
World of Warcraft
Our WoW test is run at High quality settings on a lightly populated server in an area where no other players are present to produce repeatable results. We ran at 1680 x 1050.
Starcraft 2
We have two Starcraft II benchmarks: a GPU and a CPU test. The GPU test is mostly a navigate-around-the-map test, as scrolling and panning around tends to be the most GPU bound in the game. Our CPU test involves a massive battle of 6 armies in the center of the map, stressing the CPU more than the GPU. At these low quality settings however, both benchmarks are influenced by CPU and GPU. We'll get to the GPU test shortly, but our CPU test results are below. The benchmark runs at 1024 x 768 at Medium Quality settings with all CPU influenced features set to Ultra.
Metro 2033
We're using the Metro 2033 benchmark that ships with the game. We run the benchmark at 1024 x 768 for a more CPU bound test as well as 1920 x 1200 to show what happens in a more GPU bound scenario.
DiRT 3
We ran two DiRT 3 benchmarks to get an idea for CPU bound and GPU bound performance. First the CPU bound settings:
Crysis: Warhead
Civilization V
Civ V's lateGameView benchmark presents us with two separate scores: average frame rate for the entire test as well as a no-render score that only looks at CPU performance. We're looking at the no-render score here to isolate CPU performance alone:

cause how I see it :" If you're constantly transcoding movies to get them onto your smartphone or tablet, you need Ivy Bridge. In less than 7 minutes, and with no impact to CPU usage, I was able to transcode a complete 130 minute 1080p video to an iPad friendly format—that's over 15x real time."
The majority of trancoding is going the other way- from an ipad friendly format to another friendly type format (device or not). Cell phone to pc,ipad to youtube etc.
I like the concept of the transcode,encode,but as much as with the bandwidth necesary to utilize them they are as they are 'bandwidth hungry'. And here is the first I have noticed that of telling there is hardware to facilitate the h.264 type encoding. "Hardware" to do this.
The screens from all of those cell phones in high resolution 'still'require bandwidth to utilize them. .. and so on.
I dont understand it completely but I'll attempt to stay tuned.

I find this review enormously confusing. You mix IB and SB parts/sku's throughout, without clearly highlighting which is which. On page 2, at first I thought the chart was of IB CPUs, but then realized it was a mishmash of both. Likewise on all the benchmark charts, and I couldn't even distinguish various SB/IB/core counts apart.Was this article written solely for people who have a PhD in Intel sku's ???

Could we actually see comparison with the i7-920 or i7-950 in there?Pjotr - Wednesday, April 25, 2012 - link
Thanks for the Compile test, this is all I look at to decide purchases at work.sld - Wednesday, April 25, 2012 - link
The A8 is conspicuously missing from the 2 charts showing idle and load system consumption. Why is this so?greggm2000 - Wednesday, April 25, 2012 - link
Anand/Ryan,According to the article linked below from today, it seems that Intel may be using TIM paste instead of fluxless solder in the IB chips, and if so, does this seem like a reasonable explanation for the high temperatures that people are seeing?
I'm interested in your thoughts on this... and if it's true, and if the article is correct, then Intel deliberately handicapping their chips (to possibly preserve SB-E sales?) is quite troubling to me.

Hi, is this good enough of an upgrade over a Pentium 4 for office, internet and movies?And will the HD4000 beat a ATI x1650XT?

Hey guys!Good review overall, thanks for that!
But the Quicksync section was kinda strange. No way that an x86 software solution generates worse IQ than any accelerated stuff. Unless you were comparing IQ with settings that have the x86 do recode the file in the same time it takes the other solutions. Anyway, I don't understand what you did in that section. :-)

Great review.Would it be interesting to see how it fared in a series 6 motherboard, now that it actually is backwards compatible?

The only thing I care about is how much faster this new slab of silicon will power though my x264 encoding and that's the one part of the review that was left out!Why anand, why!?
