Now the Guinness Book of World Records is judging performance in the central processing unit business.

Advanced Micro Devices, which apparently needs all the publicity it can generate, announced Sept. 13 that it has achieved the Guinness World Record for the "Highest Frequency of a Computer Processor," by overclocking the upcoming octa-core AMD FX Bulldozer-based desktop processor.

The FX CPU, which the company plans to launch commercially in several weeks, achieved a top speed of 8.429GHz, surpassing the previous record AMD did not attribute it to anybody nor say when it was set of 8.308GHz.

The AMD record was set Aug. 31 in Austin, Texas, by Team AMD FX, a group comprising elite overclocking specialists working alongside AMD staff members.

Midway through the testing process, the overclockers switched from liquid nitrogen to liquid helium to reach a lower temperature.

Here is a YouTube video showing how the exhibition was put together.
