Igor Wallossek published some fresh AMD rumors on his website. First up, his sources confirmed that AMD's Ryzen 4000 "Vermeer" CPUs have hit B0 stepping and are essentially ready for mass production. AMD is expected to announce Vermeer in the final quarter of this year, but it's still a mystery when we can expect the chips to be available in volume. One line of thinking is that AMD isn't in a hurry to release Vermeer as the current CPU lineup is very attractive versus what Intel has on offer.
Next, Igor confirms earlier rumors about Cezanne, the future Ryzen 5000 series APU. Expected to be released at CES 2021 at the earliest, the 7nm Cezanne features Vega20 integrated graphics. There will be high-performance Cezanne-H chips as well as low-power Cezanne-U models. Cezanne is still in A0 stepping so still in early phases of validation.
Interestingly, it's said that the 7nm Van Gogh APUs will feature Navi21 integrated graphics. Van Gogh is also in A0 stepping and will be used for mobile, low-power Ryzen 5000 APU. Van Gogh is rumored to stick with Zen 2-based cores though, so it has better integrated graphics than Cezanne but it lacks the Zen 3-based CPU.
For the combination of Zen 3+ based cores and Navi-based integrated graphics well have to wait for the 5nm Rembrandt. This part is expected in 2022 and may launch as the Ryzen 6000 APU series. Rembandt allegedly uses RDNA2 based graphics.
