Btw, Chinese OS is a real issue. That's why the push for replacing Western computers is a much harder issue than what we previously discussed. Back when this first came up in May, there was a lot of question about who can actually fill this mandate. The market is huge. 50 million desktop will need to be replaced! That's a lot of computers.
There were speculations about Huawei and Lenovo supplying the computers. Who will be producing the CPUs and that included Kirin, LoongSon, Zhaoxin, Phytium, Hygon and others. Even for software, there questions about which OS to use. Regardless of the answer, I think the party that wins most of these orders will have a lot of resources and money to become a serious player in CPU world and OS world. All the software developers in China will be developing to this OS. I don't think there is any reason to limit this to one vendor, but they will all need to use domestic chip producer for sure.
We know up to this point, Phytium orders for a couple of million CPUs for SMIC is probably among the larger advanced node orders. 50 million will take up a good portion of SMIC SN2 production over the next 2 years.
Recently, a 100% domestic computer called PT620L3 was offered using Loongson 3A5000 CPU which probably uses SMIC's 12 nm process and UOS operating system. Seems like aiming to fill the criteria of completely domestic. No idea how good or usable it actually is.
