Navi31 GCD/MCD transistor count
To the best of my knowledge, *separate* transistor counts for Navi31 GCD/MCD were not disclosed by AMD, only 58B total. Whoever added them here didn't cite any source, yet I seem to remember where the numbers of 45.6 and 2.05 came from – Tom's Hardware, who didn't cite any source whatsoever. What's more important, these numbers don't make sense: resulting density for GCD is higher than densest smartphone SoCs, while that for MCD is lower than many 7nm designs (whereas the opposite is true: GPUs are less dense than smartphone SoCs, and SRAM-only chips should be *much* more dense than random logic). Transistor counts which start making sense are ~40B for GCD and ~3B for MCD with densities of ~130 and ~80 Mtr./mm² respectively (or even less for GCD and more for MCD).

RX 7900 M die size
The specs table for the mobile products states that the die size of the 7900M is 529mm2. I can't find any source that verifies this. Since it has 4MCDs instead of 6MCDs like the 7900 XTX, shouldn't it's die size be smaller? 529mm2 is obtained from adding the 306mm2 GCD + 6x 37mm2 MCDs. So if the 7900M only has 4MCDs, it's die size should be 306 + 4x 37 = 454mm2 2600:1702:5B80:24F0:20D3:44A5:2350:177C (talk) 12:12, 9 January 2024 (UTC)
