AMD claims that the microarchitectural improvements in Jaguar will yield 15% higher IPC and 10% higher clock frequency, versus the previous generation Bobcat. Given the comprehensive changes to the microarchitecture, shown in Figure 7, and the additional pipeline stages, this is a plausible claim. Jaguar is a much better fit than Bobcat for SoCs, given the shift to AVX compatibility, wider data paths, and the inclusive L2 cache, which simplifies system architecture considerably.
Some impressive in-depth reporting on the architecture which powers, among other things, the current generation of game consoles.

then add another 80€ for the ram (gddr5 is expensive, but it's not that expensive)
you know, gddr5 is not superior to ddr3
they both have their weakneses and strength
there is a reason why we use ddr for the cpu und gddr for the gpu

Yes. I know. Latency vs Speed (in oversimplification).
And APUs love speed.
However we can not test any other AMD APU with GDDR5... So here PS4 may out or under perform compared to exact APU chained to DDR3.
(If I'm wrong, and there are such test, they way, I would kill for the link )
Also since its GDDR5 RAM, AMD could build its controler from ground up offering features not present in current get APUs on PC (like fully hw memory coherency between CPU i GPU)

Those GDDR5 RAM kill that assessment.
And we still have no reliable API that is equivalent to PS4 low level api. (Mantle aint finished yet)
So not only PS4 have better RAM then is available to PC build (AMD APUs love RAM!), but also still should be able to push more data, compute more, and render more, then in Win/Lin/OSX.
PS ... but I will go Lin + AMD APU next time I go shopping anyway
