AMD already working on Navi 41

VideoCardz highlights a fresh set of leaks originating from Twitter leaker Komachi. While AMD's Navi 21 is still a couple of months away from us, evidence has been found of not only a Navi 31 but also a Navi 41 GPU.

The upcoming Navi 21 (aka Big Navi) reportedly has 80 CUs for the full chip, which translates to a maximum core count configuration of 5120. It's believed that "Big Navi" will ship in 12GB and 16GB GDDR6 editions. However, word is also going around that AMD hasn't made chip production orders yet, which implies a launch is not going to happen until November at the earliest. For a sooner launch, the chips would already need to be in production.

Next is a rumor about Navi 31, the successor to Navi 21. Not a whole lot of details here but word on the street is that Navi 31 will use a chiplet design similar to the multi-die system AMD is using for its Ryzen processors.

Lastly, traces of the Navi 41 have also been found, but that next-gen high-end GPU is unlikely to hit the market before 2022.

4. NV3X GCD/MCD means probably Graphics Complex Die/Memory Complex Die of Navi 3X (Navi 31).
5. Mero is custom, confirmed.
6. Navi 2X Family has Navi 24 (like the MI200, it hasn't been taped out yet).
7. There is Navi 41.
