Intel overclocks Sandy to 4.9GHz

Written by Fudzilla staff


Using a stock cooler
Intel has shown off the overclocking potential of its upcoming Sandy Bridge processor to a group of journalists at the IDF.

The sample in question was a K-series part, with an unlocked multiplier and Intel managed to push it all the way to 4.9GHz on air cooling. However, Intel did not disclose the stock clock of the processor used in the demo.

An Intel rep told journalists that the OCed sample managed to outperform a 12-core Opteron in Cinebench, which bodes quite well for Intel, although it sounds a bit overly optimistic.

VR-Zone believes that Intel used a Core i7 2600K, with a stock clock of 3.4GHz, so it turns out that the CPU was overclocked by 45 percent with a box cooler. With aftermarket coolers, the processor should be able to go over 5GHz.

Impressive, but still expect the same from Bulldozer.

In any case, Intel wants me to shove my expensive P55 based Big Bang Trinergy + i7 860, where they are not supposed to be shoved, because they were too greedy to enable pin compatibilty + bios update to disable the on board gpu. The gpu will be useless anyway.

Well, not gonna happen!

and how cherry picked was this chip?
and the 12 core they beat... was that the 12 core 65watt TDP 1.7ghz one?

so they used more power to inch out the 12 core (cause if they beat a faster one they probably would have told us which one)

and was the intel one running optimised code write just for it (using say AVX)? and the AMD one running stock(non-optimised) code?

not saying sandy bridge is going to be bad, just adding some perspective to intels claims.
and I still think bulldozer is a much more interesting design.

Hmmm... What if they're talking about Cinebench Single CPU scores rather than multi-CPU... That would explain a lot :-*

Was thinking the same thing... 4.9GHz on stock cooling? Naaahh! For one core in turbo mode, maybe.

Of course if you ran Cinebench off a GPU it would gind both Intel and AMD chips to dust.

What is with all the AMD fanboys that spit vitriol and mark down posts ? You act like a bunch of jealous children. Whining about cherry picking, Do you think they add fairy dust to make a special wafer.
This is awesome news for the enthusiast/overclocker/gamer. 32nm quads approaching 5ghz on beta bio's/motherboards. Running on air, in a closed case for over 24 hours.

How much is it going to cost a gazillion, billion dollars?

do you know anything about chip production at all? EVERY chip is slightly different, and so are their maximum over-clock and maximum/useful/optimal voltages.

so whether its cherry picked or not is VERY important.

if 1 in 20 reach this speed, then Intel is on the money, if only 1 in 10.000 are able to repeat this feat then this is nothing but hot air.
