The difference between Xenos and RSX in raw specs is very slight. The RSX has 24 pixel-only pipelines that do 2 vector ops per cycle, and it also has 8 vertex-only pipes that do one vector op per cycle. The Xenos has 48 pixel-or-vertex pipelines that do one vector op per cycle.
Correct, but note with regard to those 48 ops vs 48 ops per cycle, on the Xenos you would perform vertex ops dragging down the potential pixel shader op figure. The more vertex ops you dedicate the lower this figure, in comparison with the PS3 there's no real top potential advantage to unified shaders.
But IMO the RSX and Cell should also be looked at together to reveal the PS3's true potential, the RSX was designed to work hand in hand with the Cell.
