Just to fixed... PS3 had a ~250 GFLOPS GPU. |
Ah, see, this is the sort of thing I'm willing to trust. PS3's architecture is well-known, and likely to have been well-tested and confirmed. Since it's not easy to find this sort of information on the net through a google search, I went with the number I could find, even though it seemed a bit high. I only have a problem with your Wii U claims because you're making absolute statements based on speculation, rather than solid facts.
And it seems reasonable to me - the PS3 would have a very slightly more powerful GPU than 360, but held back by lack of eDRAM. The Wii U GPU is running somewhere in the vicinity of 2x the speed of the PS3 GPU, and has eDRAM to help it. Then, the PS4 will come in somewhere around 3-4.5x the power of the Wii U in terms of GPU (but possibly still lacking in terms of eDRAM), with a comparable CPU, with the next Xbox being somewhere between the two (2-3x the power of the Wii U), assuming that the leaks are accurate.
This basically sets it up much like the 6th generation in terms of power, with the Wii U playing the role of the PS2, the next Xbox playing the role of the Gamecube, and the PS4 playing the role of the original Xbox.
For the sake of the comparison itself, here's the numbers for that generation, based on what I can find (if there's an error, I'm sure someone will spot it):
Gamecube - 1.6 GFLOPS CPU, 9.4 GFLOPS GPU
Xbox - ~3 GFLOPS CPU, ~18.6 GFLOPS GPU
PS2 - 6.2 GFLOPS CPU, GPU isn't really a GPU
My understanding is that the PS2, because of how it was made, had to use the CPU to do a lot of the sorts of calculations now done on a GPU, and its graphics chip was mostly just a display system (that is, it tooks the results of the calculations done on the CPU, and drew the resulting shapes into the screen buffer). If I'm in error, let me know.
Anyway, the net seems to be fairly solid about these numbers, on the whole. And if we treat CPU and GPU together (since it's hard to do anything else in this case), the Gamecube comes out about 2x the power of the PS2, and the Xbox around 3.5x the power of the PS2. Pretty much exactly where the three systems are according to the leaks and our Wii U approximations, if combining CPU and GPU.
