 PS3 was ~300-400, PS4 is 1.95TFLOP so 5x increase


First off, the PS4 has 1.84 TFlops of GPU compute power, secondly, the PS3 only has a GPU with 228 Gflops (0.0228 Tflops), so the PS4's GPU is actually an x8 increase over the PS3.  

Also, what is sort of funny is the fact that the PS4's CPU, while being much simpler to program for, is actually less powerfull than the PS3's Cell Processor.

It really makes sense that the cpu is not as good, because a large part of the cell power is used for graphic/physic. Doing so much on the PS3 CPU was already outdated and proved to not be so efficient (compared to the better gpu they could have afford with a simple cpu). I don't blame them for this failure because it's quite a noble action to try and invest so much money and time in a new custom hardware designs to create an impressive gap. Some people even say that Sony first designs didn't even have a proper gpu. By the way TFlop has always been a terrible measure of comparison between different architectures.

I can't predict the power of the next generation, but if the next gen come earlier, it will be very difficult to provide a power gap with a 400$ product, based on PC architecture, and without a massive loss.
