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.

Yeah, the clock speed doesn't mean much to me anymore - that became an exposed myth long ago.

How about a FLOP measurement? Or maybe a benchmark based or MURPHY or something similar?

Or still better yet: Graph500.

It isn't really a myth, where clock speed alone is the benchmark for performance. With the same design, high clocked chips will have a higher performance. We can assume that AMD is not going to go to a new design where you need higher clock speeds to get similar performance to the previous generation chips. So, if Bulldozer is faster on a per-clock basis compared to K10.5, and at the same time, Bulldozer is able to hit 4GHz sustained speeds all the time, not just in turbo mode, that DOES give us quite a bit of hope.

Remember, Bulldozer will be released with the high end being 8-core(4 modules) running at 3.6GHz normal, 4.2GHz turbo for the INITIAL chip release, and will be sold for $320 for the CPU. In multi-threaded applications, that should be a very solid performer, even if it does not deliver better performance per clock. Considering many are happy with the performance of a Phenom 2 x4 at 3.2GHz and above, Bulldozer SHOULD be seen as a nice step up.
