I think hes not questioning it because china, but because nm between different fabs isnt comparible. E.g. finfet nm isnt the true nm used by older definitions of what nm means, which is why intel for instance, changed their naming on its fab process to match the rest of the industry. (E.g “Intel 7” is actually a well processed 10nm traditional definition chip that has that name because its conparible to TSMC 7nm)

We’ll see what the performance is like when the chips start making their way to the market.
