The allowed limit is 4,800, so the RTX 4090 is about 10% "too powerful."

...

but Nvidia will likely build in some wiggle room — to ensure overclocking as an example doesn't become a problem. Assume a clock speed of 2.7 GHz and we get a maximum number of SMs of 108.

Like what is preventing them from just shipping 4090 cards downclocked to 2.4 Ghz, and then letting China figure out how to flash a 2.7Ghz BIOS onto the cards? I guess just Nvidia just doesn't want to get in trouble with the US government?
