> ...so the extra effort is just installing ROCm? (vs the Vulkan devtools)
The problem with ROCm is that for non-bleeding edge AMD cards you have to install an out of date unsupported version of it because the $current version does not support your card. And that means containerization woes. If you're going to spend $800 on a top of the line current generation video card anyway then you'll have fewer problems (for a few years).
Also, the vulkan vs. rocm performance difference for non-bleeding edge non-top of the line cards is smaller.
