I wouldn't go that far. Nvidia and even Intel have had hardware-accelerated features in Blender (RTX-acceleration and Optix, respectively), so this is more about getting them back on the same level. I do really like AMD GPUs though, I'd be interested to see how this performs on their APUs with the Vega graphics.
According to other posts, this won’t support Vega graphics; RDNA1 is the absolute minimum, with RDNA2 being the oldest architecture officially supported. Guess we’ll have to wait for new APUs to see how this fares.
