AMD's A10-5800K hits 7.3GHz under liquid nitrogen
AMD's A10-5800K has reached an impressive 7.3GHz under liquid nitrogen with two cores disabled, with 5.1GHz the record so far for air cooling and all four cores active.
According to validated CPU-Z results first collated by German-language hardware site PC Games Hardware, those willing to risk blowing up their new £90-ish processor have managed to get the chip running as high as 5.1GHz on air, before being blown away with a 7.3GHz overclock powered by liquid nitrogen.
First, the more reasonable air-cooling performance: CPU-Z user NAMEGT reached 5.1GHz with the unlocked A10-5800K based on a 51x multiplier on a 100MHz bus speed at a core voltage of 1.616V. Impressively, that figure was achieved with all four cores active simultaneously - something that the liquid-nitrogen crowd were unable to duplicate.
For those who prefer their cooling a little less practical, CPU-Z user GASBK_TW managed to hit an impressive 7.3GHz using the same A10-5800K chip by boosting the core voltage to a panic-inducing 1.956V. As a result, the chip managed to run at an eye-watering 62x multiplier on a 118MHz bus speed. Although that's certainly impressive, in order to achieve such a high CPU-Z-validated overclock two of the processor's four cores needed to be disabled - crippling the performance for multithreaded applications.
Even with such high overclocks, the Trinity family of APUs is unlikely to make much of an impact against Intel's Core i7 and even i5 family: the weakness of Piledriver's x86 performance means that it struggles to compete even when overclocked. For those looking to build a budget-friendly rig capable of playing most games with the graphics settings dialled down a little, however, it's likely to prove popular - and with figures like these available, a little overclocking could make the chip even more of a bargain.

So damn funny if you think of it. Speed is nothing without torque :)
This maybe stupid, but if two half the cores are disabled but the rest that remain are running at over double the speed, would that not increase performance?
It's done purely to see the maximum mhz it can do.
I was thinking more in theory, so in the future, what would be better? 2 cores @ 7.3ghz or 4 cores at 3ghz
In theory completely depends on the application, and whether it can actually take advantage of multiple cores :)
Given that a core is not a completely discrete CPU, i.e. there is resource sharing I would imagine that the higher clock speed would win. Even if a program could use 100% of each core it should still be slower in theory.
Thing is, it will always be easier to add more cores than more speed, so its fairly irrelevant. You'd need a 6.8Ghz dual core to match a stock 3570k. If you can do that, you could just make a 5Ghz quad core for less money which would have even more performance.
Dout we will ever see a 5ghz release chip from AMD or Intel in the near future.
Companies more and more are hiring 'pro overclockers' to help them with new products.
Technologies that are in top of the line boards now to do this kinda thing filter down through to lower end products over time.
So while it is for fun, I think there is a benefit.
I agree, but willy waving has been a pass-time for a long time. If it wasn't overclockers wouldn't bother.
10Ghz is the mark to hit. Intel is clearly better in most arenas, but it will be a long time before they wave their willy in that particular arena.
Me? I want performance per cycle. But that is a bit like a women saying she prefers a guy with stamina, to a guy with a big...thingamy. It may well be true, but bragging rights are everything.
