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. 

ok i see now what you're saying, but to be fair the cpu is hardly ever the bottleneck unless we're talking about either an extremely ambitious game or a very poorly coded one. Arma 3 would be an example of both cases in 1 single game on PC. On the consoles pretty much doubling the gpu number of shaders and clock speeds will make it quite easy to hit the minimum of 60 fps at 1080p for pretty much any game out right now and coming up anytime soon.

i would say that if we want to improve the AI for games we should start improving the cpu, i'm desperately hoping Sony will push for a cpu upgrade now that we know how low priced polaris 10 is :)
