The render posted by VideoCardz shows the internals of an unidentified Ryzen 5000 APU. The image below compared to a Ryzen 3000 Renoir APU shows that the Cezanne APU is larger than its predecessor mainly due to double the L3 cache (16MB VS 8Mb) using the new Zen 3 cores.
The AMD Ryzen 5000 series of APUS will come with cores up to 8 cores and 16 threads paired with 8 graphics cores (it is unknown if it is Vega or Navi) as can be seen in the render.
The Ryzen 5000 series are expected to be announced during CES 2021.
