If you were wowed by those Japanese modders who overclocked their stock CPU to 7GHz, wait till you hear about IBM's latest foray into the world of ultra-fast computing: together with researchers from the digital camera-hating Georgia Institute of Technology, Big Blue has managed to overclock a chip to an unheard of 500GHz. Granted, the model they used already had a blistering native clock speed of 350GHz to begin with, but we're still floored that you could actually coax a small silicon wafer into operating at an incredible half-terahertz. As you probably suspected, there's no way to achieve speeds like this at room temperature, so the team froze their high-performance silicon-germanium chip to a super-chilly negative 451-degrees Fahrenheit, which is just eight degrees above absolute zero. Unfortunately, after learning about this breakthrough, electronics giant Sony apparently felt that consumers would no longer be impressed with their much-hyped Cell processor, so they've once again delayed the PS3 until IBM can make the liquid helium-cooled CPUs suitable for mass production . Expect the 500GHz PS3 to hit stores sometime in 2011.
