LoongArch will win 
Rough Weixin post translation by DeepL:
Recently, the Hebi Municipal Government joined hands with the Municipal Education Bureau and other departments to introduce nearly 10,000 units of Longxin 3A5000 computers into the classrooms of nearly 50 primary and secondary schools in Hebi Municipal Direct and Hebi Qibin District. These computers are based on the independent Dragon architecture of the Longxin 3A5000 processor, equipped with a domestic UOS operating system, installed WPS office software, Extreme Domain teaching (operation and maintenance) management software and a full set of genuine licensed software, and through the classroom management to the teaching, programming, national/provincial and municipal management platforms and a total of 104 applications, to help the city in the realization of the education industry in the education industry, the basic hardware equipment as well as education and teaching The company has taken a solid step forward in realizing the independent control of basic hardware equipment and educational teaching and learning applications in the education industry.

When people speculate on when the Year of the Linux Desktop will finally happen, I always believed that Linux adoption will not make it past 10% through its superior technical merits alone. To go over 10%, state actors will have to be involved. China is paving the way for the Year of the Linux Desktop to finally happen. But this is the first step. The next step would be to crack down on Windows and Mac OS (the rationale being that they’re just spyware for the NSA) so that the only desktop OS allowed in China is a Linux distro. The step after that would be for major tech enterprises like Adobe and Microsoft to finally develop and release Linux versions of enterprise software (Acrobat, Photoshop, Office, Teams, and so on), the rationale being that since the vast majority of Chinese PC run Linux given Windows/Mac OS crackdown, by not releasing Linux version of their enterprise software, they’re just leaving money on the table. With the number boost from Chinese PCs and Linux versions of enterprise software available, the floodgates will truly open.
UOS is based on Deepin (originally Hiweed, lol) is based on Debian, btw.
Loongson is originally based on MIPS. CPUs seem fast enough for office type stuff.
Couldn’t find out what sort of graphics chips are in these things.
LoongArch is their domestic RISC ISA that isn’t related to MIPS, which is what the chips in this post are. They’re actually pretty solid and compare performance wise with relatively modern low-spec x86 equivalents from Intel & AMD (you can see some basic benchmarks towards the end of the YouTube video I linked below).
Loongson CPU approaches traditional x86 performance in new benchmarks
LoongArch is cool and based, but I take issue with the phrase “isn’t related to MIPS”. LoongArch is a massive advancement, but MIPS is very much in the DNA of the architecture. This post by one of the very prominent people in the LoongArch community does a very good job illustrating the differences and many many similarities.
Maybe “isn’t related to MIPS” was a bad way to word it, woops. I meant it as in it’s their own ISA that doesn’t require a license from MIPS Technologies/Imagination/whoever owns the rights to MIPS these days, wasn’t denouncing it’s similarities to MIPS. Even the Loongson kernel developers themselves said “LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V”. Sorry for the confusion to anyone who made have read my earlier post!
