Intel Sandy Bridge performance


Intel's new Sandy Bridge 2600K at 4.9 GHz on a Corsair H50 did p6058 in 2:04, 31,000+ ppd. That's 33% faster than an i7 @ 3.8 GHz and nearly 72% more ppd. Extrapolating to -bigadv, it's going to make frames on p2686 of about 23:00 for ~56,000 ppd. Scale it up to 6 cores and put two of them on a SR-2 class motherboard and you could expect 8:00/frame, ~272,000 ppd.

And this is supposed to be a mainstream platform? Is there going to be a new high end socket soon? Do 1155 processors fit in 1156?

New socket. The i7 2600K is a mainstream desktop product, priced at $317. AC is going to cr*p when he see's how high intel has raised the bar!

I suppose I should provide a link to the article and note that 4.9 GHz was attained at a higher vcore than I would consider for long term 24/7 use. It looks like 4.6 to 4.7 GHz would be fine on the stock cooler though. 4.7 GHz was reached at 1.375 v and it ran 4.5 at stock voltage. It was an engineering sample being reviewed, so the real world ones may not be as fast.

I guess we'll wait and see until they are out and people here start buying them. And I just bought i7 parts, drat. Oh well. At least least I'll be pushing out a lot more PPD soon even though there is a new tech that can potentially push out a lot more...

I just bought i7 stuff too, but I don't care too much. I waited this long so I can afford it. I'm guessing I won't be able to justify the price for sandy bridge.

At $317 for an i7 2600K, and you have to get the K series if you want to OC, it couldn't be that much more expensive. An i7 950 is $294 on the egg.

Clock for clock comparisons would be nice...seen any of those?

I figure the SB is just over 10% better clock for clock. It's hard to compare because of the way turbo boost works.

$90 on the processor and probably as much more for the latest motherboard to run it on, would mean spending $180 more to go with the 2600 K and make 20,000 more ppd. You save back on the cpu cooler, because the K series ships with a pretty good heatpipe cooler.

And with the higher PPD/kWh you save $$$ or even $$$$ in the long haul too.

4.9 GHz was all it would do using a Corsair H50. It might be all it would do using anything.

That is absolutely INSANE!!! Makes me wish I hadn't just purchased another i7 1366. I guess if I'm going to stick with it then I need to keep an eye on the hardware rumor boards like I used to b/c I had NO idea this was coming.

I was hoping we would get cheaper 6-core 1366 cpus... with SB here now the demand won't be there and it'll likely end up the 6-cores will stay more expensive or just disappear.

I expect the early adopters will pay a dear premium for a 2600K. Newegg still has the i7 970 at $900. How would you feel if you plopped down the money to buy one of those and then read about the 2600K and saw the retail price is going to be $317.

I'm fairly certain there are 6 and perhaps 8 core SB chips in the roadmap. Intel's goal is to bulldoze Bulldozer after all. But Harlam may be right, why produce a 6 core 1st generation (1366) i7 when the 4 core 2nd generation is as fast?
