> That's impossible because Apple has bought up most of TSMC's 3nm production capacity. You could try to approximate by comparing Apple M4 Max against NVIDIA B300 but that'll be a very one-sided win for NVIDIA.

Have you not heard that Intel's Lunar Lake is made on the same TSMC 3nm process as Apple's M3? It's not at all "impossible" to make a fair and relevant comparison here.
