AMD's Ryzen 7 5800H CPU which is going to be part of the Cezanne-H family of high-end mobility Zen 3 processors has been spotted within Geekbench by TUM_APISAK. This is the first time we get to see AMD's next-generation high-performance mobility CPUs which will be replacing its existing Renoir lineup (Ryzen 4000H).

The AMD Ryzen 7 5800H is based on the Zen 3 core architecture and as such it should be part of the Cezanne-H lineup which is the direct replacement to the Renoir-H Ryzen 4000H CPUs which utilized the Zen 2 core architecture. The AMD Ryzen 7 5800H would be directly competing against Intel's Tiger Lake-H family of high-end processors which are launching in the first half of 2021.
