AMD thinks the reason Nvidia is ahead of them is bad marketing on their part, and good marketing (All is AI) by Nvidia. They don't see the difference in software stacks.
For years I want to get off the Nvidia train for AI, but I'm forced to buy another Nvidia card b/c AMD stuff just doesn't work, and all examples work with Nvidia cards as they should.
At the risk of sounding like Jeff Ballmer, the reason I only use NVIDIA for GPGPU work (our company does a lot of it!) is the developer support. They have compilers, tools, documentation, and tech support for developers who want to do any type of GPGPU computing on their hardware that just isn't matched on any other platform.
