| flagstaad said: So based on this calculation... how many times more powerful the Orbis? Using the same metric, how many times the PS3 was more powerful than the Wii? It is obvious that the power difference was going to be present, how big is the real question, big enough so 3rd party developers don't make a Wii U version of their games? not big enough?+ Also, from prices and costs, I think it is a U$400 machine without loss, so Sony will try to sale it at 450 with a bundled game or a year of PSN+ included |
We can do look at Wii vs PS3/360 fairly easily, since the numbers are pretty much all available.
Wii: 2.9 GFLOPS CPU, ~12 GFLOPS GPU
360: 115.2 GFLOPS CPU, ~240 GFLOPS GPU
PS3: 218 GFLOPS CPU, ~400 GFLOPS GPU
It's worth noting, though, that the PS3 had no eDRAM, so while it may have had a technically faster GPU, it was limited badly by bandwidth.
Anyway, to compare Wii with 360, you get a very big CPU difference, and a GPU difference of about 20x. Note that the GPU numbers for 360 and PS3 are "official" numbers (like the 1.8 TFLOPS number given here for Orbis, assuming they're actually real), as opposed to real numbers (which tend to be lower, because chips rarely run at 100% capability) - Wii numbers are purely real numbers - they've been determined through testing, as the official numbers haven't been released.
It's worth factoring in, when looking at these numbers, that games were mostly optimised for 720 or so on 360 and PS3, and so the effective difference is smaller. But we're probably still looking at 8-10x difference.
Even based on 400 GFLOPS for Wii U, the difference between it and the PS4 would be only 4.5x, making it a much smaller difference than the 20x between the Wii and 360 (with an even bigger gap to the PS3). If we assume the more likely 480-540 GFLOPS range, then you're looking at 3.33-3.75x faster. And perhaps worryingly, there's still no mention of eDRAM or similar being included with the GPU or CPU (360 had 10 MB of eDRAM, Wii U has 32 MB of eDRAM, PS3 had none).
