Peak performance Xenon, 77 GFlops. Source: Forbes/IBM
Microsoft once claimed the Xenon's peak performance is actually 115.2 GFlops, this appears to be a very common misconception. The Amiga community buddy who wrote that Cell article linked to aboves, provides the following explanation:
"The 115.2 figure is the theoretical peak if you include non-arithmetic instructions such as permute. These are not normally included in *any* measure of FLOPs."
"If you want to count non-arithemitic peak figures, the usable Cell components in the PS3 will get 268 Gflops (6 SPEs + PPE) - over twice that of the 360."
Note the 268 GFlops figure does not take into account the GFlops SPE used by the PS3's CellOS. (which isn't available under Linux)
