What makes PS4 unique is its integrated GDDR5 for both CPU and GPGPU. The real milestone PCs have to reach  or work around before they can actually outsmart PS4 with their OS Kernel limits. It should take a year or two.

AMD has been pushing for HSA design for a couple years now, and their next gen Kaveri APUs that are due this year will aparently offer a GDDR5 Bus so system builders will be able to do that in low end PCs and laptops by the time PS4. And unified GDDR5 isn't really an ideal situation for many workloads as GDDR5 has higher latency than DDR3 which will hurt performance. And is very much not ideal in the PC space as  it must be soldered onto the motherboard which means it is not upgradable. 

Like I said, maybe it's going to be a year when low to mid range PCs will have mastered the PS4 architecture. Right now GDDR5 8 GB is ideal for next gen console games unlike PCs with Kernel limit and higher latency in comparison without unified GDDR5.
