Let me set this one straight before I start as I can already hear the trolls gathering steam; this is NOT the PS4 processor and it likely never will be and yes, we all know PC can be more powerful, so now that we have that out of the way, let’s move on. The x86 Jaguar cores that sit at the heart of the PlayStation 4 do things a little differently to most modern desktop CPUs, and the combination of Radeon HD Graphics Core Next Technology makes them a potentially formidable desktop solution compared to today's current AMD APU offerings. While they won't be as powerful as the PlayStation 4 APU (at least for now) the chips will be similar in architecture.
“Everything that Sony has shared in that single chip is AMD intellectual property, but we have not built an APU quite like that for anyone else in the market. It is by far the most powerful APU we have built to date, it leverages intellectual property that you will find in our A-series APUs later this year, our new generation of APUs, but none that will quite be to that level of sheer number of cores, sheer number of teraflops,” - John Taylor, head of marketing for AMD
It is unlikely that we will see an 8 core APU in this format any time soon. Desktop PCs in general don't benefit from such things in a lot of applications, not unless AMD can do something radical with their design. The A-Series Kabini chip is similar to that of the PlayStation 4 APU and is also tipped to feature Jaguar X86 cores, GNC technology and it is also likely that we will see a quad-core variant of Kabini bearing a vague resemblance to the PlayStation 4 CPU.
