I wonder about the size comparison between the M1 Ultra and surface area of the equivalent 'Ryzen CPU + Radeon GPU + RAM :D'

- ohgodplsno 5y agoA 5950X is 285mm² in total (and made with TSMC 7nm). An RTX3080 is 682mm² (and made with Samsung 8nm). A 16GB DDR5 die seems to be about 75mm². RAM aside which is Apple's actual performance differentiator, all of these eat the M1 Ultra alive in their respective categories.
- lhl 5y agoGoing 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)
