China is almost entirely dependent on the US industry for semiconductors and processors, an addiction that it is well aware it needs to break. That is coming in many ways: for server processors, the first iteration is Hygon, a domestically produced licensed version of AMD’s EPYC; for desktop CPUs, one of the domestically manufactured products is the Zhaoxin Kaixin family of CPUs based on the LuJiaZui microarchitecture.
One of these desktop CPUs has finally been noticed in a commercially available desktop — the RG-CT7800 from Ruijie Networks.
In many ways, the RG-CT7800 is an unremarkable PC that looks like the Intel NUC family. It has the 2.7Ghz version of the Zhaoxin KaiXian KX-U6780A chip in BGA and comes with two DDR4 slots, USB 2.0, and a 256GB SSD. Nothing exceptional.
The Zhaoxin KX-U6780A is available at 1910 on a single-core rating and an 8670 on a multi-core rating. That is approximately comparable to a modern high-end Intel Atom, or 2012 era four-core Intel Core i5-3550U.
Nonetheless, the place this will get interesting is the way it follows China’s “3-5-2” plan. That is Beijing’s command to remove China’s public sector from foreign technology.
By 2020-end, 30% of the technology infrastructure must be domestic, while by the end of 2021, this number climbs to 50%, while the remaining 20% would need to be changed by 2022-end.
The RG-CT7800, while technically unremarkable — will be an ideal cog in the machine for this plan. Its house will be on the desks of lots of China’s office staff in the public sector or at state enterprises, changing their
Regardless of China’s efforts to free itself of overseas technology, there’s an irony in all of this: so many parts within the Zhaoxin CPU, the core of Ruijie’s centerpiece of future Chinese domestic office computing, come from Taiwan.
