Didn't David Wang promise yearly cadence? Also wth is N31 entry in MacOS? It's obviously not something RDNA3 based.
Did he? For Zen they've mentioned they're on a 12-18 month cadence. I can't recall anything specific for graphics. Why can't it be RDNA3?
process drop navi 2 next year , navi 3 in 2022 makes sense to me
or RDNA3 is the process drop
So it will be late Q1'21 at best by the time they launch the entire RDNA 2 stack, maybe even Q2 for N24. And Q3 by the time mobile variants will be out. I don't see them launching the next gen in just the next quarter (i.e. Q4'21). Large GPUs on new processes take a lot of effort, and I don't think AMD is still in such a position that they have the engineering resources to do so much in such short periods of time. Even Nvidia took ~2 years between Maxwell, Pascal, Turing and Ampere. I expect AMD to launch minor refreshes of the desktop chips late next year, with RDNA 3 following in 2022.
What about rumors about the existence of other versions of Navi21 with HBM2? The memory bandwidth level for tandem from HBM2 and Infinity Cache is very interesting. Maybe this option will appear in Apple Mac Pro systems.
Infinity cache further obviates the need for HMB2 in consumer GPUs, though it could perhaps be used for premium mobile solutions for extreme power efficiency. HBM2 + Infinity cache should be a good fit for CDNA though, and I wonder when that's going to launch. Certainly should be soon if its meant to go into supercomputers by mid 2021.
