Zhaoxin’s KX-7000 x86-64 processor

Chips and Cheese takes a very detailed look at the latest processor design from Zhaoxin, the Chinese company that inherited VIA’s x86 license and has been making new x86 chips ever since. Their latest design, 世纪大道 (Century Avenue), tries to take yet another step closer to current designs chips form Intel and AMD, and while falling way short, that’s not really the point here.

Ultimately performance is what matters to an end-user. In that respect, the KX-7000 sometimes falls behind Bulldozer in multithreaded workloads. It’s disappointing from the perspective that Bulldozer is a 2011-era design, with pairs of hardware thread sharing a frontend and floating point unit. Single-threaded performance is similarly unimpressive. It roughly matches Bulldozer there, but the FX-8150’s single-threaded performance was one of its greatest weaknesses even back in 2011. But of course, the KX-7000 isn’t trying to impress western consumers. It’s trying to provide a usable experience without relying on foreign companies. In that respect, Bulldozer-level single-threaded performance is plenty. And while Century Avenue lacks the balance and sophistication that a modern AMD, Arm, or Intel core is likely to display, it’s a good step in Zhaoxin’s effort to break into higher performance targets.

I find Chinese processors, like the x86-based ones from Zhaoxin or the recent LoongArch processors (which you can buy on AliExpress), incredibly fascinating, and would absolutely love to get my hands on one. A board with two of the most recent LoongArch processors – the 3c6000 – goes for about €4000 at the moment, and I’m keeping my eye on that price to see if there’s ever going to be a sharp drop. This is prime OSNews material, after all.

No, they’re not competitive with the latest offerings from Intel, AMD, or ARM, but I don’t really care – they interest me as a computer enthusiast, and since it’s highly unlikely we’re going to see anyone seriously threaten Intel, AMD, and ARM here in the west, you’re going to have to look at China if you’re interested in weird architectures and unique processors.
