Did the Wii U force Sony to cut how much power the PS4 will have?

In this thread: people using PC standards to say what console hardware can do. Remember the PS3 GPU was a 7900GT that doesn't even have programmable shaders. We also don't know the clockspeed or shader count of it; I doubt Sony is using an off-the-shelf die you could find in a laptop.
