Phoronix is speculating that the next PlayStation will likely be powered by a Ryzen CPU/APU based on information gleaned from Simon Pilgrim’s LinkedIn profile and recent GitHub submissions. Pilgrim, who serves as one of Sony’s top programmers, appears to be spending much of his time tuning Ryzen for a future product. It's interesting that Sony is working on upstream LLVM improvements specific to AMD Zen processors when they aren't currently shipping any Ryzen/EPYC-based systems. But let's not forget that the PlayStation 4 is powered by a semi-custom AMD Jaguar CPU with GCN Radeon graphics. On top of that, Sony indeed uses LLVM/Clang as the compiler for the PlayStation 4.
