AMD have actually made several attempts at it.
The first time, they went ahead and killed off their effort to consolidate on OpenCL. OpenCL went terribly (in no small part because NVIDIA held out on OpenCL 2 support) and that set AMD back a long ways.
Beyond that, AMD does not have a strong software division or one with the teeth to really influence hardware to their needs . They have great engineers but leadership doesn’t know how to get them to where they need to be.
This is it, it's an organisational skill issue. To be fair, being a HW company and a SW company at the same time is very difficult.
