The new GPU isn't that much faster then the one in PS3. Yes it's more effiecient, but it has to be when the speed barely improves, and the CPU is sourced from a laptop, and something like only 5x as powerful and 1.5x as fast. I know you can't measure brute power by spec alone, but when the majority of components only see 3-5x improvements, and the GPU and RAM alone see greater improvements, it's hard to argue that the PS4 is 9x or more powerful.

I can't beleive I just read that.
A Geforce 7800 class GPU is not that much slower than a Radeon 7850 class GPU?
I suggest you compare them.

There is a Vast, I mean vast difference in computional power between the 2 chips, not just sheer performance but capability.
And it seems you completely missed my point earlier, even if the CPU is only twice as fast, developers can leverage some tasks that would normally be processed on the CPU onto the GPU, the GPU is actually very good at doing heavy floating point math that can be easily threaded. (Not possible on the PS3, due to the heavy fixed function and old Geforce 7 class chip.)
Besides, console manufacturers have never taken CPU performance seriously.

That's why PS3 never really reached it's maximum, it relies heavily on CPU performance, and most people didn't design games which used it. I think now that the PS4 and One mirror PC specs a lot more, people will be able to push the systems better.
I'll look at those links later, gotta go, but even if the GPU takes on CPU tasks, and even if the GPU is the biggest improvement in the PS4 (except RAM) and the most crutial, it's still only one component. If the CPU is sourced from a laptop, and only a few times better then the one in the PS3, a good GPU can't just make that fact dissappear.
