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:

It's interesting to me that this article doesn't include any temperature measurements. I have been hearing that Ivy Bridge has got temperature issues. Could you update the article with those numbers? I'm aware that the article on undervolting and overclocking has some numbers, but none at stock voltage and clocks as far as I know.Stuka87 - Monday, April 23, 2012 - link
I was just going to post the same thing. Where on earth are the temp measurements?Anand Lal Shimpi - Monday, April 23, 2012 - link
Ian's article thoroughly covers the thermal issues, and did include a stock clock graph with voltage scaling:http://images.anandtech.com/doci/5763/Stock%20Spee...
Take care,
Anand

Thanks for responding Anand.The issue I see is in the future, people will look for this review, and not know to look in another article for temp readings.
And I know the other article did have a temp graph, but it did not have the bar graph comparing it to other CPU's like we are used to. I actually have no clue how it compares to a SNB chip after reading this article in terms of temperatures. It would be great to have that information as it aids in building a new system.
Thanks!

Okk...so the A8-3870K beats it in almost every gaming benchmark and they are marketing the HD4000....pretty bad for intel. Trinity will completely destroy Ivy bridge then it seems. Every generation, one company is slacking off behind the other...it's always like that. Next year, intel will take the crown..then the year after it will be AMD...and so on.N4g4rok - Monday, April 23, 2012 - link
Not so sure about that actually. I think they're going to fork in two different directions, with Intel being your high compute power desktop friendly option, and AMD being the go to for laptop, notebook, and ultrabook-esque form factors. Unless trinity mucks up big time, AMD will have the IGP thing down. for a while.JarredWalton - Monday, April 23, 2012 - link
I think you're wrong on the "AMD being the go to for laptop..." part. AMD will be the go-to option for people that want an inexpensive laptop with better IGP performance. As I note in the mobile IVB article, mobile Llano GPU performance isn't nearly as impressive relative to IVB as on the desktop. Anyway, AMD will continue to lead on IGP performance with Trinity I'm sure, but there are very large numbers of laptop users that don't even play games. Of course, the highest selling laptops are still going to be the least expensive laptops.DanNeely - Monday, April 23, 2012 - link
For mainstream laptops the real factor is probably going to be battery life. AMD needs to catch up to Intel with power management to get beyond niche products.seasalt - Monday, April 23, 2012 - link
Why is it listed as 77W when the ones already being sold are clearly marked 95W on the boxes?http://www.nordichardware.com/news/69-cpu-chipset/...

It's in the article..."Note that max TDP for Ivy Bridge on the desktop has been reduced from 95W down to 77W thanks to Intel's 22nm process. The power savings do roughly follow that 18W decrease in TDP. Despite the power reduction, you may see 95W labels on boxes and OEMs are still asked to design for 95W as Ivy Bridge platforms can accept both 77W IVB and 95W Sandy Bridge parts."
