Both Playstation 5 and Xbox Series X uses custom Zen 2 and RDNA 2 parts
Microsoft and Sony shared technical details about their upcoming generation of consoles. They are both powered by AMD’s ZEN 2 arhitecture on the CPU side and RDNA 2 architecture on the GPU side. While Microsoft is going for more of a traditional console route by using fixed clock speed on CPU and GPU, Sony will pursue variable speed on both components that is more similar to what’s happening on the PC side of the things. Xbox seems to offer more raw horsepower on the paper but Sony seems to offer better loading times with custom NVME controller for the SSDs. One thing is for sure that we will see very powerful consoles in the upcoming years.
