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.

8.4gig is not nearly as cool as you think mr AMD (pun intended)
I call this post "How to amuse,entertain and impress a potential customer"
Indeed, we knew the other day that AMD did 8GHz and I explained that. What we now know are the full techy details of how they did it and that these new CPUs can work at much colder temperatures than previously possible. I had hoped this would interest people here? :)
Using nitrogen and helium to reach near absolute zero seems pretty hardcore techy to me! :rockout:
w1zzard's take on previous posts on other threads suggests that the performance of the chip won't be so hot for everyday use, so I'm betting that he knows something we don't. ;)
Man, the suspense is killing me! :laugh:
Oh and my best oc was on the E6300 in my sig, 107% on air.

Liquid helium and near-zero is so damned cold you couldn't and wouldn't be handling it bare-handed out of a thermos flash or holding your hand to shield the evaporating gases (like the video showed). The video is therefore fake and is just a "imaging" for the sake of PR, and the actual superclock was not achieved "live" in the way they were pretending.
We also learned that the "random CPUs in a box and the 4th one did it", well that box was cock full of pre-cherry picked samples.
We also heard that AMD broke the GUINESS World Record. But no such record previously existed.
In my mind, there is only one question: HOW MANY untruths were told in that PR stunt, and given the number of untruths, do I feel ethically compelled to avoid such a dishonest company? (and I'm still sitting on that question, but I'm getting awfully close to the answer).
Cherry picking is of course necessary for these kind of records. One do not just send a random guy to break the 100m speed record, you need years of conditioning. Cherry picking is a bit different, but same idea: only a certain lucky few have the right combination of factors to allow them to attempt to break the record.
I think the fastest P4 chips went only to 8Ghz, so this might be the fastest clock speed ever achieved on a consumer x86 processor. I might be wrong though.
There are no untruths, just different forms of interpretation. From my eyes, this is a perfectly fine PR with your usual amount of spin.
Thing is ethics has nothing to do with it at all . Performance is king and if the performance is there then cool if not we will all soon know then ... :cry:
