There hasn't been any specs on the PS3 leaked yet or even speculated, so I'm not sure about PS3 beating XBOX ha ha, considering XBOX has... well :
* CPU will use three 3.0GHz PowerPC cores, each with 32KB L1 cache, 32KB instruction cache, and the three share 1MB of L2 cache. Later alpha decks only featured two cores.
* The graphics will be handled by a “next-gen” 500MHz ATI post-X800 adapter
* There will be 256MB RAM—no word on what type; memory cards will range from 64MB to 1GB
* There will be no “next-gen” (i.e. Blu-ray or HD-DVD) drive, but instead a dual-layer DVD
* There will be an optional hard drive (as we heard before)—no word on final size
* There will be a USB 2.0 camera for 1.2-megapixel shots and VGA-quality video
* 5.1-channel audio is handled in software—X3DAudio to be exact (no word on in/outs)
