Streaming multiprocessors. That's the reason. Nvidia has an extremely complex SM architecture that CUDA is based off of and AMD/Apple focus on simpler ones because they thought it was more power efficient (oops, it's less power efficient: https://browser.geekbench.com/opencl-benchmarks)

This is such a surface-level factor in the discussion that I don't even know why you'd be offering your advice on Nvidia if you can't tell why people own their hardware in the first place. We've been having this GPGPU discussion for like 12 years at this point... people insisting on their opinions without understanding what Nvidia does is how we got in this mess in the first place.
