| haxxiy said: You are way overshooting both the GC and the XB GPUs. First it seems like you are either counting the XB GPU as 8 pipelines, where it does have only 4, or you are placing an insane ammount of operations per second on each pipeline, very unlikely considering we know very well what's inside of each in those times of non-unified shaders. It wouldn't be able to come even close to a decent performance with its memory bandwidth if either were the case. Second even with the fixed-function hardware inside the Gamecube's GPU it wouldn't go beyond 8 gigaflops. So it's more like... GC - 1.9 gigaflops CPU, 8 gigaflops GPU XB - 2.9 gigaflops CPU, 11.1 gigaflops GPU Meaning about twice the PS2 and perhaps four times the real performance of the Dreamcast. Four times, by the way, is about the same differene we're seeing between the Wii-U and Durango/Orbis specs. |
The GC numbers come from Nintendo themselves, and have been verified. The Xbox numbers come from a book about the Xbox that is known to be accurate, wherein the total is given as 21.6 GFLOPS across the entire system. The 18.7 GFLOPS for the GPU, which includes pixel shaders (the other part, other than the 11.1 GFLOPS that you refer to), is calculated by subtracting off the 2.9 GFLOPS CPU from the total.
