Any PC with a dedicated CPU and GPU will be infinitely more powerful than the APUs used on consoles.
I'm sorry this is completely wrong.
The PS4 leverages dual quad core 1.6ghz Kabini class CPU's on a proprietary ring bus with a near HD7870 equivalent GPU sharing 8GB of unified GDDR5 system memory (system memory and VRAM are one and the same in this system).
The combined compute performance of both quad core CPU's combined is comparable to an i3-4130T or Athlon 750K. Nothing particularly chart topping, but that is certainly not infinitely less than the compute performance found in popular high end gaming CPU's, in fact, many budget gaming PC's are built with similar compute performance. Unfortunately, you can't really compare the hardware directly like this, because the console has several tricks up it's sleeve that no current discrete CPU and discrete GPU combination on the desktop offers....
When software is developed for a game console, the developers only need to write code for one specific hardware configuration. They don't have to include legacy support, they don't have to worry about broad compatibility, they don't have to make performance sacrifices in the software for compatibility reasons. In the case of the PS4, this means they can exploit HSA/hUMA and GPGPU compute and use a platform optimized compiler. The result is lean software that runs more efficiently, and, software that treats the GPU as an extension of the CPU for a large list of general compute instructions. Suddenly, the fact that the CPUs in the PS4 combine to something comparable to a low end i3 is irrelevant, because the compute performance available in a fully functioning HSA environment with platform optimized and compiled software can scale to many times greater than the CPU itself by offloading work to the GPU. Leveraging just 10-20% of the GPU on the PS4 for general compute instructions can double the effective CPU performance. The advantage of platform specific software, is that the compute overhead required to achieve the same performance outcome is lower than on the desktop, so we can't even really compare the hardware specifications directly anyway, as they run different software.
When software is developed for the PC industry, it is programmed and compiled for broad compatibility. As a result, the software is naturally more bloated and less optimized, has little to no control over scheduling optimizations, and of course, the PC industry has not yet adopted HSA/hUMA system architecture, and the few systems on the desktop that support this technology are largely irrelevant to the gaming ecosystem at this time as they are too weak, so desktop PC games obviously aren't taking advantage of that technology so can't really scale compute needs into the GPU very well.
Yes it's possible to build PC's that are more powerful on-paper than a PS4, but to claim that any PC with a dGPU and CPU is infinitely more powerful than a PS4 is highly inaccurate, especially when we factor in the differences in software layer overhead and optimizations.
In fact, a desktop PC with an i3-4150 or FX-6300 and an R9 270 or similar GPU, is going to be very comparable to the performance of a PS4, not infinitely more powerful.
