Yes, another fine job. So with 7 SPEs we can say for every cycle the SPEs provide 2 DP FMADD and the PPE 1 DP FMADD giving 6 DP flops/cycle. 3.2 Ghz gives 19.2 peak DP GFlops which means for reference that I2/P5 could match this peak at 4.8 Ghz although how much a Cell could sustain in practice is not certain. Coincidentally by having 3 PPEs the Xenon in Xbox 360 could match that DP figure with its SP rate being 76.8 Gflops vs Cell's 204.8 so it doesn't look so outclassed as one would think given Cell's hype. I have also heard development Cell kits are only at 2.4 Ghz. Anyway they both sound like great distributed computing clients I hope Sony and Microsoft allow them to be used in that ancillary fashion.
