Joint venture between AMD and China. Effectively, China (technically a Chinese company) bought Zen IP from AMD and is now producing the CPUs themselves. The deal does not extend to newer Zens and I remember some nice legal wrangling to make sure joint venture is covered by x86 license. Initially these CPUs were intended to only use Zen cores but SOC/offcore parts were supposed to be custom but now that these CPUs have been seen in the wild, it is pretty much just rebadged Zen. In another thread someone noted one of the financial documents stating a $60M boost from license payment of this deal.
