Where are you getting your numbers from?

RSX was 176 GFlops.

Cell was 12.8 for each SPE so 12.8 x 6 (6 SPEs available for games): 51.2 GFlops

Total = 227.2 GFlops

RSX 

 

http://www.ps3devwiki.com/wiki/RSX

 

• Floating Point Operations: 400.4 Gigaflops ((24 * 27 Flops + 8 * 10 Flops) * 550)

Nvidia said this btw.

CELL

. PlayStation 3's Cell CPU achieves a theoretical maximum of 230.4 GFLOPS^[3] in single precision floating point operations and up to 100 GFLOPS^[4] double precision using iterative refinement for the solution of linear equations.

OK, so I made a mistake on the Cell processor. I was thinking of double precision floating point performance for some reason. Even then, with only 6 SPUs available to devs it comes to 150 GFlops (6 x 25 GFlops). The theoretical 230 GFlops numbers is for the full 8 SPE Cell processor (I'm guessing the PPU contributes 30 GFlops so 180 GFlops total?).

As for the RSX, I'm not sure I believe that figure, partly because it comes from NVidia and is likely just marketing tripe, partly because the 7800GTX never topped 200GFlops (so 400 is absurd considering the similarities) and partly because in the same wikipedia link above is a link to the RSX article that states it's 176 GFlops (http://en.wikipedia.org/wiki/RSX_%27Reality_Synthesizer%27).
