i dont see that being the case.... ony way anything offsets cpu is if the dev moves some cpu based tasks over to the GPU. But ad long as the work is on the cpu, only way u can go up to 60fps from 30fps is if you hsve a CPU that is teice as powerful. 

Better explanation if the PS4s CPU is being maxed on a game running at 1080p@30fps, then the only way to rn that game at 1080p@60fps on the neo is if the neos CPU is capabale of teoce the performance than whats in the base PS4. 

We can get more stable framerates thanks to the GPU and lots of eye candy, but as long as the CPU is in a 33ms pipeline.... all you get is 30fps

i'm not following, what do you mean by the only way to get from 30 to 60 fps is by having a twice as powerful CPU?

so let's say (to simplify the argument) that I'm playing battlefield 4 on PC with processor X and a GTX 670 getting about 60 fps on average in high quality.

if i want to double the fps count to 120 i should:

a) get processor Y with double the frequency of processor X, but keep the same gfx card

b) get a gtx 970 and keep the same processor X

 

Which one of these scenarios do you think will double your FPS?

 

edit: just to help out, here's a reference benchmark for the same gfx card testing the fps output with different CPUs

Thats why in the example i gave i said "if you are maxing out the cpu ome the base ps4"

Look at it this way. you have gpu tasks and u have cpu tasks  to get a game running at 60fps both of them.have to finish their work load in 16ms per frame. 

If you have a CPU that can finish that in 4ms but a gpu that does it in 16ms, you are still gonna hit that 60fps target. In this csse upgrading your gpu will be able to increase your overall framerate csuse the CPU was strong enough to begin with to handle higher framerates. 

Int he case of the PS4, ehere both CPUs are pretty much identical between the base and neo based on rumors. If a game is maxing out the cpu already on the base mode and running at 30fpsl, to be able to double it on the neo the neo would need to do all the cpu work the base model does but in half the time. Get it now?

It doesnt matter how powerful your GPU is, if the CPU is a bottle neck then your framerate will still suffer. And vice versa.
