AMD "Cezanne" APU Spotted: Retains Renoir's iGPU, Updates CPU to "Zen 3"
AMD's 5th Generation Ryzen "Cezanne" APU sprung up on SiSoft SANDRA database, with big hints as to the areas where the company could innovate next. Apparently, "Cezanne" is a very similar silicon to "Renoir." It appears to feature the same iGPU solution, based on the "Vega" architecture. We're now learning that the iGPU even has the same core configuration, with up to 512 stream processors, and a likely bump in iGPU engine clocks over the Ryzen 4000 "Renoir" chips.
Much of the innovation is with the CPU component. Although the CPU core count is not yet known, the company is deploying its "Zen 3" microarchitecture, which sees all cores on the silicon sharing a large common slab of L3 cache. The "Vega" based iGPU should still perform better than the solution on "Renoir," as it's assisted by higher engine clocks, and possibly a higher IPC CPU component. In the SANDRA screenshot, the iGPU was shown bearing 1.85 GHz engine clocks, which amounts to a 100 MHz speed-bump compared to the engine clocks of the Ryzen 4000H and 4000U.
