A Factor 5 employee (who goes by the alias ?Han Solo?) has purportedly leaked the specs to the Nintendo Revolution. 1 dual-threaded IBM Custom PowerPC 2.5 GHz core with 256KB of L1 cache, 1MB of L2 cache, and maybe a rumored L3 cache as well.

256MB of 1T-SRAM for an ATI Custom-based RN520 600 MHz GPU that will support up to 2048x1268 resolution, though HD support is still being decided.
