Going a bit further, since the chips are all on different processes (Apple on TSMC N5, AMD on TSMC N7, and Nvidia on Samsung 8N), it might also be worth looking at transistor counts. The M1 Ultra has 114B transistors, a 5950X has 19.2B transistors, and a 3080/3090 (GA102) has 28.3B transistors. (at 864mm2 (2 x 432mm2 M1 Max's), that's a density of ~130MTr/mm2, which is in the ballpark for TSMC's max density for N5 (est. 170MTr/mm2) - N7 max density for reference is ~90MTr/mm2)
