Recently rumored: impending AMD layoffs in China, in the Radeon Technology Group.
Speculation: Maybe RTG is moving development elsewhere due to increasing US restrictions that block sending high-end GPUs and HPC accelerators to China. And/or increasing competition for expert employees, with Chinese domestic GPU chip companies that are receiving government grants. (Implies next generation Radeon may be slower to develop as new GPU software teams might have less experience. New teams might be difficult to motivate to learn intricacies of waning GCN GPU generations as well as current RDNA GPU generations, even though CDNA accelerators are similar to GCN.)
