According to Taiwan reports, Chinese manufacturers Xiaomi and OPPO are developing proprietary chips with 5G support. Moreover, the work, apparently, is in full swing because, according to rumors, they should be ready by the end of this year.
It seems that the reason for this was the story with Huawei and the US sanctions – after Huawei, due to the restrictions imposed, was unable to produce Kirin processors, other Chinese companies decided to start their own production.
By the way, Xiaomi already has a proprietary Surge S1 chip. But it came out in 2017 and was only available in the Xiaomi Mi 5c smartphone. Its successor has been rumored recently, but it turned out to be just the Surge C1 imaging processor that debuted in the Mi Mix Fold foldable smartphone.
Unisoc, a Shanghai-based chipset company, is also working on an SoC to support fifth-generation networks.
