AMD Rembrandt with Zen3+ and RDNA2

AMD Ryzen 6000 mobile series beginning to leak.

ExecutableFix has confirmed on Twitter that mobile Rembrandt processors are to feature up to twelve graphics Compute Units (which equals 768 Stream Processors). The desktop variant is likely to feature the same silicon and the same maximum number of GPU cores. These alleged mobile specs could therefore be used by Ryzen 9 6900H(S/X) CPU which would succeed Cezanne models released in January.

Rembrandt is RDNA 2 based with a maximum of 12 CUs 🔥

The same leaker previously confirmed that Rembrandt is the only codenamed listed with mysterious and yet unconfirmed Zen3+ architecture. To this day, there has been no such confirmation on Warhol, which is also rumored to feature Zen3+.

The only Zen3+ that I've seen is the 6nm one in Rembrandt

More importantly, AMD Rembrandt would finally send Vega GPU architecture to retirement. This architecture has not been used by desktop graphics cards since Radeon VII (Vega 20), but mobile CPUs still rely on it to this day. By the time Rembrandt enters the market, we might already be seeing leaks on RDNA3 for desktop graphics cards though.

AMD Rembrandt has appeared in a leaked roadmap as Cezanne’s successor. It was also the first confirmation on 6nm architecture, PCIe Gen4 support as well DDR5 memory technology.
