Even though we have yet to see what AMD Radeon RDNA 3 has to offer there are rumors brewing about the flagship set to launch further down the line. Well-known GPU leaker Greymon55 has specified the basics of what the card is to entail and when to expect it to be released. Likely leading to the best graphics card option from the Team but it may also not be aimed at regular consumers.

The next top-level card is expected to have 16,384 stream processors with eight shader engines. Which is based on a different Navi 3X GPU than the rest of the RDNA 3 lineup. Although initially unsure if it was a real card set to release it does seem to be rumored for a 2023 launch. Whilst the full specifications are yet to be determined it can be either the next flagship or something else.

MCM or GCD?

The initial rumor for Navi 31 was two graphics compute dies (GCDs) and up to 16,384 SPs. But now it seems to be a singular GCD with 12,288 cores. This may now mean the fourth Navi 3X variant will be a bigger multi-chip design as a flagship piece with much more power. Although individually the dies may be weaker put together they should give a much-improved performance. While offering better yields as smaller dies tend to have a lower failure rate.

The suggestion is offered by RedGamingTech and they give an idea of what that card may be targeted at. Suggesting that it could be developed as a Radeon Pro workstation graphics card. And this card in particular may be a dual Navi 32 GPU from the given specs. RedGamingTech also suggests that the MCM design for normal GPUs is now expected in RDNA 4 (Navi 4X).
