I suppose if you're talking about consumer cards, I agree, support is often missing. But if we're talking datacenter GPUs, the software is there. Data centers is where most GPGPU computing happens after all. It's not ideal when it comes to hobby development, but if you're working in a professional capacity I'm assuming you're working with a modern HPC or AI cluster.

Well, to provide my own experience bringing GPU acceleration to scientific computation software, AMD got passed on because even if the software was there at the time (it wasn't), there was no way to justify spending a bunch of money buying everyone workstation AMD GPUs when we could just start by picking up basic consumer NVIDIA cards to work on for anyone who didn't happen to have one already and then worry about buying more suitable cards if needed. Of course the end goal was to run on a large HPC cluster we had access to, but for efficient development, support on personal machines was necessary. My personal dual 3090 setup has been invaluable for getting through debugging and testing before dealing with the queueing system on the cluster (Side note: it also ended up revealing another important benefit of consumer side support for GPGPU, a 3090 was easily matching the performance of a single node of the CPU-only version of the cluster, thus massively bringing down the cost of entry to an otherwise computationally restrictive topic).

  This is a very valid point. 100% AMD need better support of consumer cards to get research, university and everyday folks using their SW. The high end consumer7900 xtx are supported now, and a lot of other cards not officially supported actually work. (I've a colleague who tried it on his home computer and got it working, despite that card not being on the official list) .. . Still, AMD need to be getting more cards working ASAP
