My Core i7 3930K (6 cores, 12 threads @ 4.8ghz) manages 100Gflop in benchmarks, that means it's slower than the Playstation 4's 8-Core Jaguar and Playstation 3's Cell. - You see the point I'm trying to make? And the irony yet?

PS4 CPU is an atom like chip that can run two threads per core at 1.6 GHz, nothing great at all.

Are you comparing Jaguar to Atom? REALLY?
For starters, Jaguar is more like Brazos than Atom and in turn, Brazos is more like a full featured Athlon/Phenom Core, that's to be expected, Atom and Jaguar is from two different companies.
Jaguar doesn't have Hyperthreading, it's not an in-order design which I assume is what you were insinuating. (Latest Atom's, are Out-of-order now and removed Hyper Threading in favour of real cores, becoming more like AMD's Jaguar, performance increase was dramatic.)
Jaguar is wider and fatter, it actually has allot of similarities with AMD's K6 design in some aspects. (Like being a 2-issue.)
But comparing it to Atom? Really? Brazos could beat Atom, Jaguar is faster than Brazos on a per-clock basis.
All 8 Jaguar cores would be roughly equivalent to a 3ghz Dual-Core Core i3 Haswell processor in terms of performance, which is certainly better than last generation, where those with 6-7 year old Core 2 processors could have enjoyed the entire generation without a CPU upgrade.

Your I7 3930K is teorethically capable of more than 100 Gflops. Benchmarks never reach peak theorethical Gigaflops.
PS4 Jaguar is a much simpler processor, and thats why i compared it to Atom, also because everybody knows Atoms and should know that is not an I7. New Atoms are OOO. Anyway, Jaguar is normally compared with Bobcat, its predecesor, and its not even an Athlon. Athlons were 3 issue designs from the beginning, Jaguar can issue only 2 instructions per clock per core. There are a lot more architecture things to it, but thats not the central point of the topic.
Despite the bad core, I agree with you, 8 CPUS can achieve the level of performance of I3 in multi threaded aplications. But in single threaded ones the I3 just kill the Jaguar.
I think that the PS4 has a weak CPU, just enough for the GPU it carries. 8 GB are just enough too, considering that the OS takes almost 3 GB of it. The GPU is also just enough for 1080p. Its a balanced piece of hardware just enough for full hd.
If developers do future games as they do now, you will need 4 times the power for 4K. Dont you agree that less than that will fall short for a future gen machine?
