Sony is working with AMD's Ryzen CPU tech - and PS5 is the most likely target
A principal programmer at Sony associated with the firm's Advanced Technology Group is working with AMD's Ryzen technology, improving the Zen core's micro-architecture support within the LLVM compiler stack - a key component of a tool used in the PlayStation 4 development environment. Of course, there is no PS4 product using the Ryzen processor, leading to speculation that this is related to a prospective next-gen PlayStation 5 console currently in development.
The evidence - unearthed by Linux-specialist site Phoronix - shows the highly experienced Sony programmer making a number of commits to the LLVM github over the last few weeks, all of them related to the "znver1" architecture, the codename for AMD's first generation Ryzen processors. On top of that, information on LinkedIn confirms the staffer's involvement in compiler development for PlayStation hardware. Game credits in Media Molecule's Tearaway and Evolution Studios' DriveClub confirm that the developer is also a part of Sony's Advanced Technology Group, which serves a number of roles in the Sony organisation.
Taken at face value, the fact that the platform holder is improving a key part of the developer toolchain for a new processor line that none of its products currently support is compelling evidence that Ryzen will indeed form a key component of a new console. It is certainly the most logical choice for a new CPU architecture for both Sony and Microsoft as pre-production work on next-gen hardware continues behind the scenes.
