 |

Chipmaker AMD has broken a world record by souping up one of its upcoming FX eight-core desktop processors to run at 8.429 GHz. The overclocked chip was kept cool with the help of liquid nitrogen and liquid helium -- a very impractical setup for a home user. Still, AMD said simpler air- or water-based cooling systems can bring FX chips up to around 5 GHz.
AMD (NYSE: AMD) announced on Tuesday that it has been awarded the Guinness World Record for computer processor speed for an overclocked version of its upcoming eight-core FX desktop processor.
This CPU hit a top speed of 8.429 GHz with the help of specialist teams, as well as a heavy dose of liquid nitrogen and helium for cooling.
The previous record speed was 8.308 GHz.
Though the record-winning overclock and cooling system is far more complex than anything a consumer would likely use in a home, FX processors also happened to achieve clock frequencies well above 5 GHz using only air- or sub-US$100 water cooling solutions, AMD said.
No benchmarking or stress testing was used for the CPU that cracked the world record.
However, that's not important, AMD spokesperson Miriam Cox told TechNewsWorld.
"This overclocking demonstration is a way to show capability rather than what the majority of users will do with their CPU," Cox said.
How the Award Was Won
Not every AMD FX processor is capable of the world-beating speed that broke the old record.
About a month prior to the Guinness World Record test, held Aug. 31 in Austin, Texas, AMD ran initial tests to validate the overclocking potential of the FX line and learn how the CPUs would respond to a combination of extreme cold and high-voltage overclocking, AMD senior manager Simon Solotko stated. \
The processors passed the first tests, overclocking with liquid nitrogen at temperatures below -180 degrees centigrade.
The processors were also tested with liquid helium, which is even colder.
One week prior to the Guinness test, AMD experts sifted through and tested various FX CPUs to see which would perform best. Eight processors were found to be able to hit over 8 GHz when overclocked.
The Guinness world record was broken on the third of three staged runs.
