Hygon is just AMD's EPYC CPU [0]. I am uncertain if they will differentiate themselves more as time goes on, but at the moment almost the only difference in the kernel is that it has a different name. I think you're more likely to see some ARM CPUs which have comparable performance to low-end and mid-range x86 before you see a new x86 competitor [1] - the overhead to making x86 perform well is just so high that I can't imagine anyone new bothering to get into the space. VIA has been in the market forever as the third seller of x86, and despite the theoretical benefits of entering into the datacenter CPU market, they've never made that leap (though I don't know enough about their history to know if they tried). I'm hoping that ARM becoming competitive in the client CPU space ends up making the cross-compile overheads of enough drivers/kernel stuff that we can start to see some more diversity in the CPU market overall. I'm excited about RISC-V, especially now that they have shipping hardware you can play with today [2]. The Mill CPU sounds super cool in a bunch of ways, but the architecture has made so many decisions that I'm unsure will play out in practice I'm holding my excitement until I see real silicon somewhere [3] [0] https://arstechnica.com/information-technology/2018/07/china...

They might have also baked in slight tweaks or customized whatever back-doors could be included if such things exist...
It's better to think of it as a Chinese subsidiary in a franchise system.
