> On the x86 front, when AMD was desperate for cash a few years ago they setup joint ventures with China (THATIC and Hygon) and were transferring AMD's then current-generation Zen 1 architecture to China.

That's not even the whole truth. The version of Zen 1 they exported had to be nerfed in several ways in order to be given the OK for export.

Performance is much worse than comparable Zen 1 CPUs.
