No it is not. It is the same CPU but overclocked due to the extra overhead of the OS. It even performs worse with the higher clock if the benchmarks floating around are true, I didn't look into it. PS4 cpu can be overclocked anytime if there is a need for it. One CPU was overclocked at the later stages of the development cycle to keep up with the OS.

Also framerate is a function of what you are describing, not resolution. It is nice that you claim to know how things work, but just because you are saying things, it doesn't mean they are true. 

Stick with neutrality though.


Why do you think it was overclocked because of the OS? Any source for this?

After checking the original quote it seems that the overhead they are talking about is not related to the OS but the overhead in the CPU.

"Now it seems that additional overhead was found once Microsoft got its hand on production silicon, with the CPU component able to run at 1.75GHz, compared to the initial 1.6GHz target. "

I thought that sentence meant that once extra overhead was found, they needed to overclock the CPU. Sorry about that. 

Though the OS had a lot of performance problems at the launch, weren't they? That is after increasing the clock speed. It seems obvious that if it wasn't or the increase it would be worse. Though this is speculation on my part. Also I checked a few sources and they say the PS4 Cpu performs better despite the clockrate difference, which would only be explained by the OS performance.

I would imagine your speculation to be correct.  I mean I don't see any other reason for the PS4 CPU to  perform better without it overclocked.  And the One is supposedly running 3 OSs concurrently, so I'm sure that has to have some kind of impact.
