The Sandy Bridge Preview

Our Bench suite is getting a little long in the tooth, so I added a few more gaming tests under Windows 7 with a new group of processors. We'll be adding some of these tests to Bench in the future but the number of datapoints is obviously going to be small as we build up the results.
Batman is an Unreal Engine 3 game and a fairly well received one at that. Performance is measured using the built in benchmark at the highest image quality settings without AA enabled.
Gaming performance is competitive, but we don't see any huge improvements under Batman.
Dragon Age Origins is another very well received game. The 3rd person RPG gives our CPUs a different sort of workload to enjoy:
Dragon Age on the other hand shows an 11.6% gain vs. the i5 760 and equal performance to the Core i7 880. Given that the i5 2400 is slated to be cheaper than the i5 760, I can't complain.
World of Warcraft needs no introduction. An absurd number of people play it, so we're here to benchmark it. Our test favors repeatability over real world frame rates, so our results here will be higher than in the real world with lots of server load. But what our results will tell you is what the best CPU is to get for playing WoW:
Performance in our WoW test is top notch. The i5 2400 is now the fastest CPU we've ever run through our WoW benchmark, the Core i7 980X included.
We've been working on putting together Starcraft II performance numbers, so here's a quick teaser:
A 12% advantage over the Core i7 880 and an 18% improvement over the Core i5 760.

It's Anand "intel" lal Shimpi.Anand Lal Shimpi - Friday, August 27, 2010 - link
I agree that single threaded performance is important to keep in mind. Sandy Bridge had a larger ILP boost than I expected. Final silicon with turbo enabled should address that even more.We got into trouble chasing the ILP train for years. At this point both AMD and Intel are focused on thread level parallelism. I'm not sure that we'll see significant ILP gains from either party for quite a while now.
The socket move is silly, unfortunately there's nothing that can be done about that. AMD takes better care of its existing board owners, that's something we've pointed out in prior reviews (e.g. our Phenom II X6 review).
I'm not sure I'd call Sandy Bridge a kiddie chip however. It looks like it'll deliver great bang for your buck when it launches in Q1 regardless of how threaded your workload is.
Value scatterplots are a great idea, Scott does a wonderful job with them. We're going to eventually integrate pricing data with Bench (www.anandtech.com/bench) which should help you as well :)
Take care,
Anand

I'm guessing USB 3.0 support will be introduced later with a chipset upgrade. Why are you so concerned with GHz when Sandy Bridge delivers more IPC? I think having better IPC instead of more GHz is better as you'll get potentially lower power consumption.asmoma - Friday, August 27, 2010 - link
Lets just hope AMD trhows in 80 gpu cores into ontario to bring this SB igp to shame(almost the same performance but less than 10w tdp). And lets also hope they throw in those 400 cores into Llano we have been hearing about.mfago - Friday, August 27, 2010 - link
Any news on OpenCL support? I image Apple may hold off on a purely integrated GPU unless that is supported.Thanks!

Sandy Bridge's GPU does not support OpenCL. This is strictly a graphics play, Intel doesn't have an announced GPU compute strategy outside of what it's doing with Larrabee.Take care,

Is intel actually still doing anything with Larrabee on the gfx side? I thought they killed it on that end entirely and were looking at it strictly as a compute platform now.Anand Lal Shimpi - Saturday, August 28, 2010 - link
Correct - as of today the only Larrabee parts are for the HPC market. Didn't mean to confuse there :)Take care,

"Correction, you'll be able to buy it next year, but you'll get to meet her today."Sandy could be a boy too!

By the way, is it a an it, or a girl? You can't have it both ways!
