| Scoobes said: 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). |
The Cell's Gigaflop numbers have been known for a long time to be just crappy marketing speak, you need to be a Jedi to even get a tiny fraction of that performance. - Remember Sony/Microsoft have a vested financial interest to one-up the other in order to draw consumers in, so some numbers are of course bloated.
Besides, that's more than what my CPU gets in the real world, which is a CPU that costs more than 2x PS3's combined, is 7 years newer... And is generally better in every way.
Besides, Gigaflops aren't the entire story, you have single and double precision, you have integers and such which are just as important to processing performance.
Heck, Microsoft is confused on how powerfull the Xbox One is, one day they are saying 2x faster than the 360, the next 40 times faster, the next it's 8 times faster then another person says it's 10 times faster...
