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.

Hi there.. I`m currently a freelance 3D generalist.. and I was going to upgrade my old Core 2 Quad QX6700 with a Core i7 980X. But now i`m not that confident. Sandy bridge looks amazing, I was sad seeing the new socket for sandy bridge, it does not compell me to buy a new motherboard now... does anyone know if the 1366 socket will stick with the nex gen High end market? I dont want to shoot myself in the foot here.AndreC - Saturday, August 28, 2010 - link
Sorry dind`t read the last frase...Great Review btw. cheers

As noted in the Intel roadmap in the article, for at least part of 2011 they will be sticking with 1366 for the release of the Core i7 990X (to replace the 980X). However, after that the Intel performance platform will switch over to socket LGA-2011. Here is a quote from the articlea (page 3)."Original Nehalem and Gulftown owners have their own socket replacement to look forward to. In the second half of 2011 Intel will replace LGA-1366 with LGA-2011. LGA-2011 adds support for four DDR3 memory channels and the first 6+ core Sandy Bridge processors."

Yeah.. as I said "Sorry dind`t read the last frase..." but thx anyway..It`s a shame to be always changing sockets, but probabily a necessity to evolve the technology.

Having the first chips target the mainstream market is a very smart move by Intel because that's where AMD makes it's money. I'm honestly not impressed by the performance numbers, but I am impressed by the overall performance, power consumption, and pricepoints for these next gen CPUs. What I'm really looking forward to is the performance segment of Sandy Bridge.mino - Saturday, August 28, 2010 - link
Intel's mainstream is not where AMD's is.Especially in 2011.
Ontario:
. . . CPU - above Atom, under everything else
. . . GPU - 5450/Sandy class
Lliano:
. . . CPU - 2C Sandy class
. . . GPU - 5650 class (at least 3x Sandy)
Bulldozer Desktop(8C):
. . . CPU - 4C Sandy Class
. . . GPU - discrete 5750+ class
So basically AMD's platform in the Intel's "mainstream" $200+ class will be a Bulldozer with discrete GPU. Aka AMD's high end stuff.

Not sure I agree with that. From AMD's own figures, Bulldozer is significantly faster than STARS. It would be more realistic to expect Bulldozer to perform closely to Sandy Bridge, however we really need more benchmarks before we get a true idea. Bulldozer looks great on paper, but that's virtually all we have so far.In any case, you compared Bulldozer to "4C Sandy Class", which would be an 8-thread Sandy Bridge, and thus - at least relatively - high end. And I'm not getting into the core/module argument again... ;)

What I wanted to point out is that Intel sees the 4C Sandy as a "mainstream" part.Reason being they are moving HUGE amounts (compared to AMD) of $150-$250 parts.
On the other hand, AMD sees the mainstream at $100-$200 and that is a Llano market.
For AMD, Zambezi is high-end that justifies discrete GPU.
And Yes, Bulldozer 8C should compare with 4C Sandy favorably, (it would mostly go to pricing).

BD 8C is going to be up against 8C and 6C Sandy on LGA-2011 in the client space.mino - Monday, August 30, 2010 - link
am sure AMD WOULD like it that way. But no. Not really.8C Bulldozer versus 6C Sandy might actually be competitive.
However 32nm SOI is a new process so we might as well forget about 4GHz parts for now.
Also, Sandy 6C is Q4 part and 8C is most probably 2012 part.
