If your workloads are limited by single thread performance you need better software. It's why vulkan and dx12 are a thing. (The single thread limitation of committing a frame to the GPU has been reduced by an order of magnitude) It's why C++ has the parallel algorithms library baked into the language.
I get it, threading is hard. But it's honestly not that hard. It's only hard when you're maintaining some super old program with single threadedness engineered into its core architecture. (note: this is my day job) Greenfield applications since 2009 should have had threading built in as a core assumption.
AMD is doing the right thing by optimizing for multithread performance over single thread performance. Moore's Law is dead for single cores. It has been for a decade and a half.
