It’s not just about 5g. Huawei Kirin chips used to be manufactured at TSMC on their process (which is the best in the world for ARM chips), that is not allowed to happen anymore. So Huawei had to engineer their own process for making the chips, and the fact that they’re only two or three years behind TSMC now, despite all the sanctions, is incredible. They’re even ahead of Google’s own ARM tensor chips (which are just rebadged old Samsung designs).
