There is so much wrong with this... |
Im not sayint that is the best way , more accurate and definitive comparison between architectures, I just say that is the most common way to compare theoretical gpu computing power.
The best way to compare gaming hardware is with games, not even benchmarks, and games show that being the cpus of this gen consoles almost equal, the PS4 is faster having lots of games running at 1080p and the XBOXone at 800-900p because of the GPU.
That said, PS3 CPU has more theoretical flops than PS4 CPU, and some benchmarks like ubisoft show that is as powerfull.
http://en.wikipedia.org/wiki/PlayStation_3_technical_specifications
"PlayStation 3's Cell CPU achieves a theoretical maximum of 230.4 GFLOPS[3] in single precision floating point operations and up to 100 GFLOPS double precision using iterative refinement for the solution of linear equations."
Architectures are completly different and cell normally dont even get close to that flops in real life. PS4 CPU is an atom like chip that can run two threads per core at 1.6 GHz, nothing great at all.

PS4 CPU is capable of 103 GFlops
If we talk about integer performance, again the core of PS4 is dual issue, nothing great. It might be better than PS3 but it wont make a game changer
I dont care if the PS4 CPU is a little lower, a little faster or at the same level than PS3, its just clear that the PS4 design centered in a GPU 10 times as powerfull at least in Gflops than the PS3 RSX. Thats where the new gen gets its power.
If CPUs like Intel Core I5 or Core I7 runs at almost 4 GHz and issue 4 instruction per clock per core, I hope that next gen PS5 at least double the CPU performance of PS4.
In the meantime programmers will try to use the power of gpu computation to get better physics.
