Old news. ROCm works a lot better now than it did a year ago.
The point is that they care now.
Not surprising. True, the ecosystem is like early OSX vs. Windows. Eventually it'll get ported over if there is demand.
But even in the amd stack things (like ck and aiter) consumer cards are not even second class citizens. They are a distance third at best. If you just want to run vllm with the latest model, if you can get it running at all there are going to be paper cuts all along the way and even then the performance won't be close to what you could be getting out of the hardware.
