Well PS4 has modifications to bypass GPU cache and pass CPU commands direcly through the additonal bus, for any GPU Compute, which AMD added to the system's SOC. The amount of Cache in the GPU is allocated correctly based on AMD's design and I'm sure they added what is needed to make the most of the GPU in cache dependant portions of a workload.
How much of a system's performance is used depends entirely on optimization of your code design and that's something that only comes through iteration of it.
The CPU always had the same amount of Cache, unified for all 8 Cores, whether it's used for gaming or OS is immaterial, it's constant regardless of the job type.
In CPU dependent workloads it means that developers have an extra core, so they're less bottlenecked on those tasks, it's about 16.6% more performance in that area, the amount of cache available doesn't change just because this extra core has been made available to games.

Is your pic of the SSM game that we lost?
Great rundown of what it means when they say "Unlocked a core", you seem fairly familiar with VLSI...

My Avatar is from the leaked concept art Guerrilla Games did for Horizon Zero Dawn, my Sig is from Media Molecule's new game Dreams.

From what I've been able to see through searching Sony Santa Monica's game there doesn't seem to have been anything leaked as far as concept art, the only glimpse of anything was a teaser they put into God of War Ascension.

As for the PS4 tech stuff, I've just researched stuff, read Mark Cerny's interview with Gamasutra among other stuff, it's a bit of a hobby, I'm not a programmer or anything, though I wouldn't mind having a stab at game design in the not too distant future.
Here's the Cerny interview: http://www.gamasutra.com/view/feature/191007/inside_the_playstation_4_with_mark_.php?print=1
