So you have conjecture.

Truthfully not many people here are qualified to speak on the matter. But I think it could be possible. 


It isn't. Well, it is but not as reasonable speeds. You have to emulate 6 cell cores which match the six cores from the jaguar available on PS4. The Cell itself is still faster or let's say at the same speed. So emulation would have to 1:1 in terms of speed which is impossible. Than you have to emulate the PPC core on another core of the jaguar which is not even fast enough to emulate a cell core so the no time left would have to emulate the PPC core.

So just from the CPU point of view, it is not possible.


To my knowledge GPGPU compute, a completely new feature exclusive to current gen and modern PC gaming is by design allowing your GPU to handle some of the processing tasks normally reserved for a CPU. Sony went ahead and made some modifications to their pictairn based AMD graphics card which even improve upon this. You and the other guy are looking at the clock speed on the Cell, seeing it has a higher number and thinking its instantly impossible but theres more to it than that. While the Jaguar might have a lower clock speed, it still has modern day features and is far more efficient on a relative scale. If they were able to match the Cell performance with just the cpu performance on the ps4 then BC would seem far more possible. Truthfully though, this is entirely conjecture. Unfortunately no one on here has proven that I'm wrong. 

 

I really do think GPGPU would be key to PS3 emulation on PS4.
