Microsoft released the specifications of the XBox 360..
it is a beast..
With 3 CPU cores running on 3.2Ghz each with 2 hardware threads and 1 mb l2-cache each it is a powerhouse.
A remarkable feature of the XBox 360 is that it has got processor level support for MSIL (the bytecode used by .net applications).
The best thing of the XBox 360 is that it’ll be quite cheap (~150$), this probably lets the XBox360 deliver the most processor capability per dollar.
Maybe I’ll buy a few and make my own little linux server cluster with it, when the guys behind xbox-linux.org have added support for the XBox360 :-).
