It's basically a continuation of VIA's x86 tech (they sold the cyrix processors for a while if anyone remembers them). I assumed it was just copyright theft, but these are legitimately licensed x86 chips.
Apparently the current generation of these is like the Ryzen 3000 series, but I can't find any actual benchmarks, so I'll take that with a bit of salt. I doubt they will have the same power efficiency as the OP ones since the clock is apparently at 3.7GHz.
This is much cooler than I initially realised though. A viable 3rd player can keep competitor prices down so we would all benefit even if most of us aren't buying these chips
