Overclocker Andre Yang has broken the processor clock speed world record with an AMD Bulldozer chip running at a whopping 8.46GHz.
Yang's feat may prove a little embarrassing for AMD, who recently set its own Guinness World Record with pre-release versions of the FX-8150 chip, using liquid nitrogen and liquid helium cooling to set a record of 8.429GHz at a special event in September put on in conjunction with an international team of elite overclockers.
Yang used the same FX-8150 CPU and Asus Crosshair V Formula motherboard as AMD's Bulldozer attempt. According to the CPU-Z validation page reproduced below, the chip used a base clock speed of 272.95MHz with a 31x multiplier, and ran at a voltage of 1.992V. A single 2 GB Corsair memory module was used, running at 909.8 MHz (1818.16 MHz DDR)
According to a report on performance PC news site Hexus, only two of the eight cores were enabled on the chip used by Yang, as was the case in AMD's own record-breaking attempt.
