Realistically, the Zhaoxin x86 or any other Chinese alternative is at least 2 years away from mass adoption.
So do you propose to use in that time, to replace Intel/AMD processors?
I agree that Chinese companies need to de-Americanise their products so they aren't vulnerable to any sanctions.
But the alternative technology has to be good enough, otherwise best to keep it in low rate production or as a Plan B ready to ramp up.
And in the meantime, continue to improve it until it is good enough.
Loongson desktop have been used in many places in China for awhile now. It's not as good as latest Intel based one but hey running some office suites on Linux is enough for state offices.
Especially now, alot of local and central government are hurting budgetwise, getting domestic desktops are cheaper price is the way the go and most important it supports domestic players.
