For reasons that are well known, Huawei's self-developed HiSilicon chip is going to face a big test, and TSMC may not be able to continue foundry work if it doesn't get U.S. approval in September.
The good news is that Huawei's 5nm Kirin 1000 series processors are guaranteed to be available in 2020. What about Huawei's smartphones in 2021?
Huawei is unlikely to give up on the phone business, with the flagship P50 series in the first half of next year, which has previously been officially said to be in the works, and it will likely continue to use 5nm processors.
Huawei will also have new phones with 5nm processors next year, according to supply chain source @手机晶片达人. The processor is not designed by HiSilicon. That said, Huawei's P50 series next year will likely feature a third-party 5nm processor.
He didn't specify where the 5nm chips will come from, but there are only a few in the world that can design 5nm process phone chips, and combined with this year's situation MediaTek's Dimensity 2000 series is more likely.
