Igor’s Lab has also revealed new information about AMD’s Ryzen 5000 APUs that include Cezanne for the mainstream and Van Gogh for the low-power segment. Next-generation Ryzen 5000 APUs will use very different chip designs and architectures, and the first silicon for such chips is already being tested.
AMD Ryzen 5000 Cezanne and Van Gogh APUs are more detailed: Cezanne gets Zen 3 and GPU Vega 20 CPU cores, while Van Gogh relies on Zen 2 and Navi 21 GPU CPU cores
AMD’s Ryzen 5000 CPU family will consist of three different chips designed for completely different segments. The Ryzen 5000 desktop lineup would include next-generation Zen 4-based desktop processors alongside Zen 3-based desktop APUs.
The laptop segment will consist of low-TDP H-series and U-series core parts with Zen 3 cores, but there will also be a lower-level segment in AMD’s portfolio that is rumored to have used Zen 2 cores. So it appears that the Ryzen 5000 CPU family is comprised of three generations of Zen cores, however this is early information and could change as the silicon being tested is still in early revision.
AMD Ryzen 5000 ‘Cezanne’ desktop / mobility APU with Zen 3 CPU and Vega 20 GPU
So far, only the design of the Ryzen 5000 ‘Cezanne’ APUs is confirmed and, as we discussed in our last report, the APU generation Cezanne will introduce the new Zen 3 CPU architecture while reusing the Vega GPU architecture. The Cezanne family would replace AMD’s Renoir Ryzen 4000 family of APUs, which launched on laptops since April 2020 and will debut on the AM4 desktop platform in the coming months.
The Cezanne family will build on the FP6 and AM4 package for mobility and desktop platforms while utilizing new and improved core technologies. The new cores will be merged on the CPU side in the form of Zen 3, which are also coming to the Ryzen 4000 desktop CPUs codenamed Vermeer. Zen 3 desktop CPUs will be released before Zen 3 APUs for desktop and mobility platforms that could be announced around CES 2021, followed by a proper launch in the coming months.
The GPU side for the Cezanne APU line on all platforms will continue to use Vega graphics. Although this particular Vega GPU would be an improved version of the 7nm iGPU that we could see in the Ryzen 4000 ‘Renoir’ APUs. The first A0 silicon features the Vega 20 GPU and, once again, this is an internal codename for the GPU. It has nothing to do with how many compute units one might think comes with 20 CU, which is practically impossible at the same package size. AMD’s Radeon VII GPU also featured the Vega 20 GPU and was primarily due to the fact that the Vega 20 series is based on the 7nm GPU IP, while the Vega 10 series is based on the 14 GPU IP nm.
It is not difficult to say that Renoir uses the same GPU IP as it is an improved 7nm variation of the Vega GPU offering a great performance gain per CU over the original Vega cores that were featured in the Ryzen 3000 APUs.

AMD Ryzen 5000 ‘Van Gogh’: Low Power Mobile APUs with Zen 2 CPU and Navi 21 GPU
The low-power Ryzen 5000 APU segment will comprise the Van Gogh APUs. It’s unclear if these APUs will be branded under the Ryzen 4000 or Ryzen 5000 APU family, but the source points to Ryzen 5000. There is no mention of when these chips are, but previous reports have hinted in late 2020 as a possible release date. , but I hope The announcement that will take place with the Ryzen 5000 family ‘Cezanne’ will be presented at CES 2021.
The Van Gogh CPUs are reportedly also in A0 revision. Previous leaks have indicated that Van Gogh is likely to have Zen 2 CPU cores and Navi GPU cores. Although Zen 2 has proven to be a very efficient chip for the low-power segment, the most interesting part of the Van Gogh APUs will be its graphics chip, which will not only be based on a better graphics architecture than Vega, but also on the RDNA 2 AMD IP. The specific GPU for the Van Gogh APUs is said to be Navi 21.
Again, using the Navi 21 codename here might confuse many people, but like Vega 20, which is the codename for Vega’s second generation graphical IP (7nm), the codename Navi 21 could be there to indicate the second generation Navi (7nm) IP graphics. We are aware that Navi 21 is also the code name used for the Big Navi GPU, but this is why I hate to state earlier that the details of only Ryzen 5000 ‘Cezanne’ APUs are concrete at the moment, whereas the rest of the alignments are mainly based on speculated evidence from various sources.
That said, we will be able to see AMD Ryzen 5000 ‘Cezanne’ APU-based laptops with RDNA 2 GPUs up to Navi 23 discreetly. That would be a pretty sweet replacement for the existing Ryzen 4000 ‘Renoir’ and RDNA 1 (Navi 10 / Navi 14) combos we’ve seen so far. We only hope that AMD can provide us with a wider range of the Ryzen 5000 notebook portfolio using its discrete RDNA 2 graphics than what we were able to see with first generation RDNA based products.
Ryzen 5000 Cezanne APUs will compete with Intel’s Tiger Lake CPUs at launch, while Van Gogh APUs will face Tiger Lake-Y in the same year.
