http://en.wikipedia.org/wiki/Pentium_III
Microsoft's Xbox game console uses a variant of the
Pentium III/Mobile Celeron family in a Micro-PGA2 form factor.
The sSpec designator of the chips is SL5Sx, which makes
it most similar to the Mobile Celeron Coppermine-128 processor.
It shares with the Coppermine-128 Celeron its 133 MT/s front side bus,
128 KB L2 cache, and 180 nm process technology.
