Nintendo still has made no official announcement. These are based off claims from anonymous developers.
CPU speed: 729MHz
GPU speed: 243MHz
RAM: 24MBs main 1T-SRAM and 64MB external 1T-SRAM (total 88MB).
In comparision that makes it about twice as powerful as a Gamecube on paper, which is less than the Xbox 360, but I suspect that the improvement in graphics quality will be quite good. Revolution doesn't support high definition, so it needs less power and should look just as good in standard definition.
