It's not just about drivers in isolation, but what features those drivers and cards support. Support for older APIs for doing compute on AMD cards get dropped in newer drivers and newer APIs aren't supported on older cards. With Nvidia CUDA has been supported continuously for probably 15 years now, while in the AMD world you've been expected to throw out all your old code and port it to a new API every 3 years.
