Star Wars Force Unleashed II programmer has this information on custom anti-aliasing algorithm. He is comparing unified shader Xenos GPU and Cell processor with 5 SPU usage.

Typical execution times of DLAA in our current implementation are:

Xbox 360: 2.2 +/- 0.2ms @ 1280x720
PlayStation3 (5 SPUs): 1.6 +/- 0.3ms @ 1280x720

48x 500mhz unified shader GPU with GDDR3 takes almost 40% longer for same algorithm than 5x 3.2Ghz SPU with XDR. In this application, 1x SPU has double throughput per clock vs 1x unified shader unit.

That's ALL available unified shaders the X360 GPU has working on the algorithm. That still leaves 2 more CPU cores (1 SPU and 1 PPU) AND the RSX available to the PS3 vs. just 3 cores available to the X360.
