It would make sense if PS5 games don't have as much of a need to do floating point work on the CPU, since they have shared-memory access to a high-performance GPU and can do pretty much anything they want with it. AFAIK AMD has had asynchronous GPU compute support in their hardware for a long time, so I'm sure the chip in the PS5 has it.
