AMD has long announced that it will launch its next-generation graphics cards in the second half of the year, based on the Navi 3x series of cores, expected to be named the RX 7000 series. TSMC 5nm, mainly graphics processing related units, with six MCD (Memory Complex Die), TSMC 6nm, mainly graphics memory controller and other units.
According to the authoritative exposer @Greymon55, the GCD portion of the Navi 31 core is a little over 350 square millimeters.
This is a full 33% smaller than the 520 square millimeters of the Navi 21 core used in the RX 6900/6800 series, but the latter is a separate core, so it lacks direct comparability.
The area of the Navi 13 MCD section is not known at this time, but six of them would add up to a significant area, and the total area would almost certainly be larger than the Navi 21, or it would not be a separate design.
Assuming 40 square millimeters per MCD, the total area will be 590 square millimeters, almost the same as the NVIDIA AD102 core, which is rumored to be around 600 square millimeters.
Non-equal scale comparison
However, it is worth mentioning that Navi 31 core will eliminate some non-essential and obsolete modules, such as XGMI bus for multi-card parallel connection, GDS (Global Data Sharing), geometry pipeline, scan converter, etc., which can also save a lot of transistors and area.
Also, the Navi 32 core will be a similar small-chip design, with MCDs expected to be reduced to four, and Navi 33 will continue to be a single chip.
