Those cores are 28nm and I believe they were made on TSMC.
Today, the manufacture ban has China still on 28 or maybe 22nm as their most advanced node.
They had some old 14nm stuff, but last I heard, the guys that owned it greatly over-promised to the Chinese Government.
China has no modern fabrication processes and no way forward toward designing one. At present, they are headed to a state of perpetually being 5 node (one decade) behind.
