Sony Computer Entertainment revealed its next generation console PlayStation

supercomputer for computer entertainment.
PlayStation 3 will be powered by the Cell Processor at 3.2GHz, with 512KB L2 Cache; the
graphic processor is Nvidia RSX "Reality Synthesizer" at 550MHz, which is
capable of 128bit pixel precision, 1080p resolution; it has 512MB of graphics render
memory which can perform 100 billion shader operations and 51 billion dot products per
second. Nvidia RSX is said to be more powerful than two GeForce 6800 Ultra video cards at
$1000.
The PlayStation 3 will use Blu-ray discs as the media format, which can hold 6 times as
much data as DVDs. PS3 will be backward compatible with all existing PS2 and PSone
software. The machine also includes Memory Stick DUO, SD, Compact Flash slots, as well as
a slot for detactable 2.5" HDD.
