uhm... relativity !!
I read your quoted article a bit..

"...... an ASUS AMD EPYC 7773X (“Milan-X”) CPU with 64 cores has published results of 440 or 6.875/ core, but with half as many cores and older generation DDR4 (albeit with a larger L3 cache.) ....."
301 vs 440 *but* half the cores / half the energy or worse.
actually 150.5 vs 440
chip architecture is a piece of paper, that might be briliant.
actually building a chip that implements the architecture, is a veeeery difficult job, and china / india / etc
do not have the brains walking around to do that
*with*
the necessary ecosystem / tools AND experience.
there is no 5 day course for "experience"
There is enough smart people in these countries, without a doubt. but experience / tools / etc is not for sale.
And last but not least: ASML does not sell the Ultra violet machinery to China. fullstop.
