First leaks on AMD’s next-generation APUs.
AMD Rembrandt; 6nm Zen3 cores?
Further speculation on AMD’s next-generation APUs codenamed Rembrand has emerged yesterday, after @patrickschur_ provided a new update to his previous leaks.
AMD Rembrand is a codename for next-generation APU, planned for both desktop and mobile series. This is a Cezanne successor which is a successor to the current-gen Renoir itself. That said, we are talking about an architecture that is coming to new products probably around 2022.
The speculation points towards AMD repositioning both ‘Vermeer’ and Cezanne under Ryzen 5000 series. The Rembrandt would therefore launch as 6000G and 6000H series, as the architecture is expected to occupy a 45-65W performance target.
According to the latest tweet from Patrick, Rembrandt would support DDR5-5200 memory and up to 20 PCIe 4.0 lanes. This would also be the first AMD APU processor series for a new socket, rumored to be AM5. The transition to a new socket will provide support for next-generation DDR5 memory.
Update: Rembrandt with DDR5-5200 support, 20x PCIe 4.0 lanes and two USB4 (40 Gbps) ports.

A roadmap, which has been gradually released by @MebiuW over the past few months, appears to find its further confirmation. According to this (still not fully pieced together) slide, in 2022 AMD would launch Raphael, Dragon Crest (codename confirmed by the leaker himself), and Rembrand.
The architecture would allegedly launch on the 6nm fabrication process, which may not be accurate, as it has been speculated that AMD would use a 5nm process for its next-generation products instead.
