They already modified the 750 once to get better FP performance on the Gekko and nobody knows what they did with the Broadway or the Espresso afterwards. The only thing we still know is that the Wii U is incredibly efficient while not matching up in power to the X1 or PS4 is about it. We need more data than all this guess work bullshit. |
15GFLOPS is based around outdated document that stated that Wii's CPU was 2.9GFLOPS or something...
I always asked if it is possible to improve performance of PowerPC750 cores while maintaining compatibility and people said not possible yet I don't agree since it is still basically PowerPC750 design. I wonder how much they could have improved the IPC from Wii's Broadway to Wii U's Espresso... 5-10%,15-20% or higher?
We will never know except if someone gets hands on development kits and then we would probably be under NDA.
Marcan42 on Twitter is sure it is regular PowerPC750, yet I beg differ.
