Zhaoxin is a brand that makes multi-core 64-bit x86 processors primarily for use in Chinese state IT infrastructure. It's part of the Chinese Government's ambitious plan to make its IT hardware completely indigenous.
Zhaoxin's x86-64 CPU cores are co-developed by licensee VIA, specifically its CenTaur subsidiary that's making NCORE AI-enabled x86 processors. The company's KaiXian KX-6780A processor is now commercially available in China to the DIY market in the form of motherboards with embedded processors.
The KaiXian KX-6780A features an 8-core/8-thread x86-64 CPU clocked up to 2.70 GHz, 8 MB of last-level cache, a dual-channel DDR4-3200 integrated memory controller, a PCI-Express gen 3.0 root-complex, and an iGPU possibly designed by VIA's S3 Graphics division, which supports basic display and DirectX 11.1 readiness. The CPU features modern ISA, with instruction sets that include AVX, AES-NI, SHA-NI, and VT-x comparable virtualization extensions. The chip has been fabricated on TSMC 16 nm FinFET process. I found some CPU benchmark
here. The CPU looks pretty slow :(
