AMD overclocks Bulldozer to 8.429GHz
What do you get when you mix a Bulldozer CPU with liquid nitrogen? One hell of an overclock!
Bulldozer is the codename for what will soon be known as the FX range of processors that AMD is due to launch later this year.
A team of AMD engineers led by the charming Sami Makinen used a combination of LN2 (liquid nitrogen) and liquid helium to cool the Bulldozer CPU to below -180˚C and managed to snag a verified CPU-Z screenshot at an astounding 8.429GHz.
To put this into context, the previous world record, set by the Latvian overclocker Tapakah, stood at 8.309GHz, achieved on a single-core Intel Celeron D 352.
Not only is the incredible frequency achieved by AMD a great indication of the overclocking potential of Bulldozer, but it also shows that the chip doesn't necessarily suffer from the cold bugs that often plague modern CPUs.
'The record-breaking processor speed that resides in the AMD FX CPU clearly demonstrates performance gains for the new AMD Bulldozer multi-core architecture,' commented AMD's corporate vice president and general manager of its client group, Chris Cloran. 'Along with world-record frequencies, the AMD FX processor will enable an unrivalled enthusiast PC experience for the money.'
AMD has still yet to publicly announce the release date for its range of FX processors based on the Bulldozer architecture, but in the meantime you can watch the official AMD video of its overclocking record and let us know your thoughts in the forum.

I love (and currently using) Intel but MAN i miss a good fight.
NOW GIMME MY REVIEWS :D
Everything here. AMD being more broadly able to compete with Intel is good for everyone.
I wonder what kind of overclocks can be done on air.
No matter what... wow
Getting a bit of LN2 on bare skin is fine, it boils so you're insulated by a layer of gas... it's much worse to have gloves frozen onto your skin.
Terminator 2 flash back...
Meh, Leidenfrost effect only lasts so long.
No, we haven't got our review samples yet, although we have seen and played with Bulldozer; which leads onto your next question...
Although the voltage and frequency are correct, I wouldn't believe anything else in the CPU-Z screenshot. I'm not saying AMD is lying, but the chip in question was a pre-production sample, so not all the specs are correct.
+1 for that!

Don't be dry leg humping yet gents!
While these may overclock like this under nitrogen and helium what will they go to on air or under water is the more important, thing that we need to know as we already know that the 2600k/2500k will do 5ghz+ on air and potentially 5.5ghz+ under water, unyet I have not seen anything like this as I don't think anyone has been crazy enough to put 2v's through one of them yet?
I hope AMD come back to the market for the enthusiast's because then it mean's or should mean Intel will have to drop the price of there cpu's meaning saving's for people.
I must admit I have not looked at AMD for a cpu since the Q6600 came out as nothing as far as I am concerned has been able to compete against, Intel since even the 6 core cpu's cannot compete sometimes and I stress sometimes with a dual core from Intel.
I am now though looking forward to seeing what these new chips are capable of performance wise, but if they are a let down the Sandy Bridge E is where my money goes and my dad get's my current 2500K.
Confused as to what you're implying?
And damien, SB doesn't do clockspeed very well, currently the highest cpu-z anyone's got out of one is only 6044mhz
Hope to see the same for processors..
Thank's didn't know that but got to admit I am looking forward to Sandy Bridge E and Ivy Bridge to see what they can do.
Certaintly looking forward to the Bulldozer chip's under more wallet friendly cooling sollution's.
Maybe my next monster build with hopefully a custom made case will include a Bulldozer cpu as well as a monstrous water cooling setup which will include 40 fan's 4x480mm rad's with push pull and case fan's for mobo and hdd's etc etc with some 19db fan's I have seen but will have to test them all 1st.
So Intel will still probably have better performance but it'll cost more....as is the case now :D
In the park.
*gets coat*
More than likely. This is it - why put yourself in the limelight with this pointless achievement when the processor is still two generations behind it's competition. I hope for their sake the benchmarks prove me wrong, but given the price point I'd be suprised if bulldozer even comes close to sandybridge.
The first used a sub-$100 closed-loop waster cooling solution from Antec (Kühler series). I can't tell you much about the chip itself other than it is an 8-core FX processor that AMD was able to overclock to 4.8GHz using the Antec Kühler.
Next up was phase change cooling. Armed with a phase change cooler AMD pushed another 8-core FX CPU up to 5.894GHz at 1.632V.
AMD ended on its most aggressive cooling solution: liquid helium. Using liquid helium AMD was able to take Bulldozer to a new world record of 8.429GHz.
None of this tells us much about how Bulldozer will perform unfortunately. The most interesting number is likely the first number (4.8GHz) which gives you the upper bound of what to expect from an overclocked Bulldozer at home without any exotic cooling.
this sounds like it's going to be a monster if you can get those kinds of frequencies with that many cores.. the celeron d was a single core
Funny how you didn't read/missed/ignored what you quoted. That is a single core processor. OC'ing typically becomes more difficult with more cores. The two processors aren't even of comparable complexity and the many core beast set the record. This has nothing to do with being a "fanboi" (lame, overused term) of AMD as when we step to 22nm with Ivy Bridge this record may be shattered.
I paused the video in various moments to get a glance at the chip. One moment you're able to see all the data written on IHS but unfortunately I can't figure a rat's ass :(
I've also paused at the cpu-z showing on screen and the thing that got me was the fact it accused 8 core cpu but only 2 were detected from cpu-z. Also the frequency was a bit over half the announced record but maybe they were upping the clocks in that time. The TDP I thought it was too good for an 8 core.
Don't get me wrong, I an AMD enthusiast but those things made my head itchy.
Does anyone has the skills or the software to pause and clean the cpu frame were you can see all the details?
Also, traditionally a single core of a CPU can go higher than all cores-which means a 9GHz single BD core validation may be just around the corner.
These is a CPU....ATI doesn't exist anymore.
they only ran it on 2 cores, not 8
Quoted from CPU-Z "CPU Arch : 1 CPU - 2 Cores - 2 Threads"
I have to admit though, this feels more like AMD saying 'Hi we're awesome, look what we can do. Please ignore the benchmarks when they're released' which I hope wrong. That would make me a sad panda.....
As people have said, it's all very well having the freq but if the performance/mhz is terrible, won't really matter.
Look forward to seeing some reviews, maybe I can get an AMD rig if it actually performs :)
I have just such a set up ready and waiting I just need a CPU to put in it....:'(
Blade Runner sprang to mind for me
Bulldozer has just over HALF the IPC of Sandy Bridge? ....more than unlikely.
In the video matey alludes to that chip already having suffered alot of oc'ing abuse.
No. Not even wolfdale would do that. Allendale was a good 10-15% ahead of K8 at the time, I should know I had an e6300, but not even close to 50% better.
CPU-Z also said 56w TDP. CPU-Z could be wrong about half of the values it shows.
On a Max 4 Extreme no less! ;)

Also AMD did the 8GHz on a Crosshair 5 Formula

It's all just for a bit of fun. :)
/marketing done for today
At the end of the day, though, this is an overclocking for the sake of it exercise. It'll be a bit yet before we get a real taste of how BD performs. Either way, though, BD is my next build. It damn well better be an appreciable step up from the Phenom II X3 I've got now. I was more than a little disappointed to find out Llano was just Phenom cores with (an admittedly decent) GPU bolted on.
"BD is due out soon" - so I waited. BD has been delayed - I sighed but continued to wait as it wasn't supposed to be that long (2 months approx). Meanwhile there has been lots of discussion on BD: BD will beat SB, BD won't beat SB, BD has 2 cores in one so will be better than multi threading on Intel chips, It won't be better than MT on Intel chips, BD OC's like crazy but so what if we don't know how it compares to SB clock for clock, etc, etc.
I have to say, I'm bored now. Release the chip AMD or shut the **** up about it until it's available because I'm sick of hearing about it for nearly six months without it showing up. It's worse than the pre-christmas "Buy our cool stuff for the person you love or you'll never get laid again" marketing machine - and that starts in October...
IMHO. ^^
Nice to see AMD condoning safe working practices hehe.
Price/Performance ratio + low power usage + cool and silent running is what matters most to me.
Does anyone, aside from heavy multitasking power users running seriously CPU intensive tasks and VM's etc, really require more then a Core i3/Phenom 2 these days for word processing, internet browsing and gaming?
They are hardly bombarding us with marketing.
But otherwise I'm wig you pal. Just not so angry abouut it as you. Lol
Since I am already running at 3Ghz I plan to keep that as my minimum clock speed so my best option from here is clearly more cores and I am hoping AMD's new top k model will be up to the task as its been a long wait and Intel has been tempting me with every new release.
I imagine that by the time I am happy with the tech and the cost to have balanced out, Windows 8 will be out so will be a whole new build and a definitive step forward in performance whether I end up going with Intel or AMD.
I can only say that I have disdain for the regular releases intended to milk the market and would much prefer to have fewer releases with more real improvements and greater performance increases. This article certainly had me intrigued but perhaps I have become jaded and shall remain sceptical until the nice tech people out there can give us some real facts, figures and opinions and find those here on BT to be the most informative and well presented.
Other sites may provide more technical data or sometimes get there first but at least here they tell it how it is and disregard how good it might look on paper and theoretical values and give us real world uses in no nonsense clear and most of the time, in a concise manner.
