Zhaoxin, a joint venture between Via Technologies and the Chinese government, has been selling processors for various client systems for years, but recently the company rolled out its latest CPUs that some of the local PC makers position as solutions for DIY enthusiasts. At least initially, Zhaoxin’s KaiXian KX-6780A will be available only in China.

Zhaoxin’s KaiXian KX-6780A is an eight-core x86-64 processor with 8 MB of L2 cache, a dual-channel DDR4-3200 memory controller, modern I/O interfaces (PCIe, SATA, USB, etc.), and integrated DirectX 11.1-capable graphics (possibly S3 based but unknown). The CPU cores are in-house designed LuJiaZui cores, built around a superscalar, multi-issue, out-of-order microarchitecture that supports modern instruction sets extensions like SSE 4.2 as well as AVX along with virtualization and encryption technologies. The processor is made using TSMC’s 16 nm process technology.

Zhaoxin formally introduced its KaiXian KX-6000-series CPUs back in 2018, but it looks like higher-end models like the KX-U6780A and the KX-U6880A are entering the consumer market this quarter.

As it turns out, Xinyingjie, one of Chinese PC makers, uses the C1888 motherboard based on the KX-U6780A that is designed for enthusiast-grade PCs and therefore supporting expandability using a PCIe 3.0 x16 slot, two SO-DIMM slots, M.2 slots, and various internal and external interfaces. One thing to keep in mind about the Zhaoxin’s KaiXian KX-6780A/C1888 platform is of course lack of CPU upgrade path because the processor uses an BGA packaging.

When Zhaoxin originally introduced its Kaixian KX-6000, it said that their performance was comparable to that of Intel’s 7thGeneration Core i5 processor, a quad-core non-Hyper-Threaded CPU. Since then, we have not really got a proper confirmation to the claim and will certainly be interested to test the chip in our labs.

According the to the video source, this mini-PC design is expected to be available from March for consumers. Currently this is a prototype, with enhancements expected between now and the final product.

    100% correct!

    Even if it’s comparable to a 7th gen Core i3 that’s adequate for most desktop tasks, and faster than most previous gen (pre-Ryzen) AMD CPU’s so this is kind of surprising considering they’ve only been at this for a few years...

    VIA bought two x86 companies back in 90s

    Yup, and they were the first to go all in on low power CPU's, for a while they were the ones to beat in the mini-PC segment.

    Cyrix that at the time were faster than Intel . Except their FPU that was weak and eventually lead to filure.

    But the CPU was fast , very fast at the time

    I had a computer with the Cyrix 6x86 166+ back in the mid 90s. That was a fast CPU back then and until FPU games were common place, you couldn't tell the difference between it and the Intel CPU.

    Ironically, I had a 386 with a Cyrix math coprocessor (back when they were separate physical chips). It was allegedly like 10x as fast a genuine 387.

    Anton, regarding your request for them to contact you, I think you should try and send them a mail or buy it from China to test.

    I suspect Ian will be checking Ali Express/etc on a semi-regular basis for one of these to show up; which doesn't mean he wouldn't rather be sampled hardware and have a contact at the company to ask questions of if possible.

    Sadly it seems the one Ian's found is too expensive.
