AMD's Bulldozer 8.4GHz+ OC Achievement: Cooled to Near-Absolute Zero
AMD's Bulldozer 8.4 GHz+ OC Achievement: Cooled to Near-Absolute Zero
TechPowerUp recently brought you news on AMDs fantastic overclocking achievement with their new processors. Now we can tell you how it was done: cherry-picking the chips and slapping on some water cooling isn't quite enough. AMDs new processors can operate at much lower temperatures without displaying the "cold bug" - where it just gives up and goes home - and performance scales very well at super-low temperatures. The problem is that the cold affects lots of things such as timing, but more importantly, power circuits, which stop switching and just fry everything in sight - surely one to avoid. AMD senior manager of social media, Simon Solotko explains in detail how it was all done, using both liquid helium and liquid nitrogen to make the poor processor really cold. The new processor had these great qualities, according to Solotko:

It was able to take a lot of voltage, extremely low temperatures, extremely high frequencies," he said. "It was very durable under extreme overclocking. So that was awesome. So it worked well, it scaled well, it responded to cold well - all the right variables.This overclock is an impressive feat and it will be interesting to see if Intel can match it.

So they set the record. When I am ready to switch to a liquid nitrogen and liquid helium-cooled computer, I will keep this in mind. Otherwise, this is just a meaningless number achieved for publicity purposes.
It's very impressive, and the fact that you expect to haul your groceries (or do your everyday simply PC tasks) with a rocket is just insane.
Other benches will come soon, I will look to those for real performance figures. This is just something thats cool, that record has stood for a while.
All we know that more clock more performance but, reaching those clocks without any practical uses, without benchmark or without knowing if the CPU is stable is pointless IMHO
Anyway it's interesting the overclocking potential or those CPUs because that mean you could overclock it more if you cool it better with WC or something :toast:
And I agree completely on buying if the performance is right. All world records are "meh", they don't mean anything to any almost anyone on here, but usually if something means absolutely nothing to me, I just don't even post about it, as it doesn't matter. Just seems to be so many posts that are copy and paste of what you said, instead of a discussion of the actual way they hit the record, or how long the record has stood, just annoying.
I of course would like to see some real world figures as well. But I'll just have to wait for those.
Top 20th for max frequency were only with Intel crapmill celerons :D and one Bulldozer ES B2 rev.
Come on AMD, do the competition, and let the prices drop... Intel is doing too much money for himself.
I want performance info, dammit. Is my next build BD or skt2011?
we need more apps that use moar cores
