Although the CEO of Sony has already announced the entry into the last phase of the life cycle of PlayStation 4, nothing specific yet on the next console, which according to analysts of NPD should still not arrive before the autumn of 2020.
We therefore welcome this news, which however comes from a rumor and therefore should not be taken for official information, of course: based on a report published among others by Digital Foundry, the heart of the hardware of PlayStation 5 would be the Ryzen CPU. Everything starts from the curriculum of a programmer who seems to be currently working on the new console, charged in particular with "improving Ryzen's support for programming tools". It seems that we work in particular on the compiler with support for the AMD Ryzen microarchitecture "inside the LLVM compiler stack", thus evolving from the LLVM compiler already used by PlayStation 4.
All this suggests that Ryzen is destined to be a key component of PlayStation 5, because the effort to improve a fundamental part of the development toolchain to support a currently unused line of processors means that this will be the basis for new console. On the other hand, that Sony (as probably Microsoft) is destined to continue the collaboration with AMD is highly probable, therefore the transition to the Ryzen platform would be a logical consequence, considering the now mature times. It remains to be seen whether the Ryzen used by PlayStation 5 is destined to be a customized form of the one currently present on PC and in case what different characteristics it might have.
