Kirin 9000 is currently not 4G version, the chip design is prepared for 5g.
The Kirin 9000 chip is designed by Huawei hisilicon and manufactured by TSMC, using a 5nm process. At present, due to the Wassenaar Agreement, TSMC has adopted comprehensive restrictions on Huawei's chip foundry, so it is unlikely that a 4g version will appear in terms of production.
Therefore, in a long time, or even in the future, Kirin chips may not be able to achieve mass production, whether it is 4g or 5g.
As we all know, due to the sanctions of the United States, at this stage, the full series of Huawei Kirin chips can not be OEM production, of course, including the highest end Kirin 9000 series, now can only use inventory, can not be produced.
No, Kirin chips are manufactured by TSMC, and because of the ban, TSMC cannot manufacture them on a contract basis
Now the mainstream is 5g mobile phones, 4g mobile phones are not the mainstream, can not be produced depends on Huawei, personally think not.
It can be produced. The 4g version is simpler than the 5g process
