FX CPU ran at 8.429 GHz with liquid nitrogen cooling

AMD has been content to let Intel offer the pricier and often faster processors to the enthusiast desktop crowd for a while now while AMD focused on the lower price crown. In fact, the company’s value-oriented Fusion processor has been a great performer for the company.

Today, however, AMD announced that its FX 8-core desktop CPU has grabbed a Guinness World Record for the highest frequency for a computer processor to date. The processor was able to run at 8.429 GHz, beating the previous record of 8.309GHz.

The team had to resort to some extreme measures to cool the processor enough to hit that record-breaking frequency. Air or water-cooling was out and Team AMD FX had to resort to liquid nitrogen for cooling. The team included some overclocking gurus along with AMD folks in the effort. 

The clock speed of the processor was validated using CPU-Z and will go into the record book. Although AMD was able to overclock the FX CPU to "well above 5GHz" using air or liquid cooling systems that cost under $100, the team used a three-phase system to make its record run.

 “The record-breaking processor speed that resides in the AMD FX CPU clearly demonstrates performance gains for the new AMD Bulldozer multi-core architecture, which will provide x86 computing power for this CPU and future AMD Accelerated Processing Units,” said Chris Cloran, corporate vice president and general manager, Client Group at AMD. “Along with world-record frequencies, the AMD FX processor will enable an unrivaled enthusiast PC experience for the money – extreme multi-display gaming, mega-tasking and HD content creation.”

AMD has a video posted that shows the overclocking process and the record run.

I could've swore in the video they said they got to that record after they switched to Liquid Helium from Liquid Nitrogen...

yes they did.

According to Anandtech it was helium:

They achieved 4.8 using an ANTEC water cooler.

They also have pricing info listed in another article. Top of the line proc is 3.6/4.2turbo:

I was asking myself something similar: is going from 8.309GHz to 8.429 GHz really an advancement in CPU tech or in cooling tech? After all, it's less than 1.5% faster. Still a record, but not ground breaking at all.

Most people feel that Intel has been way out in front of AMD in terms of CPU design. Now, one test of a design is how far it can be overclocked and still be stable. Yes, you could say that there have been advances in cooling, but the real kicker is that Bulldozer can be clocked at that speed, and it is well beyond what the current K10.5 chips could be overclocked to, even with extreme cooling.

Remember, there have been difficulties in getting the current generation AMD processors to go much beyond the 4GHz mark, and from what they have said, they are hitting 5GHz on high-end air cooling

AMD marketing can claim that an AMD chip is listed in the Guiness Book. In marketing, image is everything, reality takes a back seat.

What version is Firefox on? v6? Geez, and here I thought it was just at v5...

So you spend a couple of bucks to make your product look 'awesome' to some beginner builders. "Should I buy this or this. Wow, a world record speed!"...

"So you're vastly overstating the impact of marketing in the CPU consumer space in my opinion."

I think your vastly underestimating human silliness.

The top speed is a suicide shot, but the 5GHz on high end air implies that with the current implementation of Bulldozer, 4GHz and 4.5GHz with an eight core chip SHOULD be a realistic expectation. And this is with the initial Bulldozer release, which will have a lot of room for improvements.

Many people have not expected much from AMD, even with the new design, so the real question here is what sort of performance Bulldozer will provide at a given clock speed. Bulldozer SHOULD be faster per-clock compared to the current Athlon 2/Phenom 2 chips, the question remains how much faster. Eight core at 4GHz does sound rather tasty at this point, even if Intel still has an edge.

Records are meant to be broken all the time ;)

Every record is groundbraking. It makes the competitors run too.

Please keep in mind that the 8.309GHz record was with a single core processor. The new 8.429GHz record is with an 8 core processor with more advanced features... hence greater complexity.

I believe all but one module was disabled. This does allow them to claim "2" cores over one, but the relevance depends a bit on how well their module architecture works, which has yet to be revealed.
