Huawei has unveiled its Mate 40 smartphones claiming they feature a more “sophisticated” processor than Apple’s forthcoming iPhones.
However, Huawei has had its supply of the chips cut off because of a US trade ban that came into effect in September.
That means that once its stockpile of the new Kirin 9000 processors runs out, it faces being unable to make more of the Mate 40 handsets in their current form.
At present, only Taiwan’s TSMC and South Korea’s Samsung have the expertise and equipment to manufacture 5nm chips, and both are forbidden to supply Huawei with them or any other semiconductor product whose creation involves “US technology and software”.
The States says the move has been taken on national security grounds, but Huawei denies posing a threat.
