alt Hacker NewsI honestly can't figure out which Radeon GPUs are supposed to be supported.
The GitHub discussion page in the title lists RX 6800 (and a bunch of RX 7xxx GPUs) as supported, and some lower-end RX 6xxx ones as supported for runtime. The same comment also links to a page on the AMD website for a "compatibility matrix" [1].
That page only shows RX 7900 variants as supported on the consumer Radeon tab. On the workstation side, Radeon Pro W6800 and some W7xxx cards are listed as supported. It also suggests to see the "Use ROCm on Radeon GPU documentation" page [2] if using ROCm on Radeon or Radeon Pro cards.
That link leads to a page for "compatibility matrices" -- again. If you click the link for Linux compatibility, you get a page on "Linux support matrices by ROCm version" [3].
That "by ROCm version" page literally only has a subsection for ROCm 6.2.3. It only lists RX 7900 and Pro W7xxx cards as supported. No mention of W6800.
(The page does have an unintuitively placed "Version List" link through which you can find docs for ROCm 5.7 [4]. Those older docs are no more useful than the 6.2.3 ones.)
Is RX 6800 supported? Or W6800? Even the amd.com pages seem to contradict each other on the latter.
Maybe the pages on the AMD site only list official production support or something. In any case it's confusing as hell.
Nothing against the GitHub page author who at least seems to try and be clear but the official documentation leaves a lot to be desired.

Exactly.
I have a 6700 XT with 12 gig ram and a 5700 with 8 gig ram.
If i ctrl+f for either of those numbers on the GH issue, I get one hit. For the 6700, it's a single row that has a green check for "runtime" and a red x for "HIP SDK". For the 5700 card, it's somebody in the peanut gallery saying "don't forget about us!".
HIP is the c++ "flavor" that can compile down to work on amd _and_ nvidia gpus. If the 6700 has support for the "runtime" but not HIP ... what does that even mean for me?
And as you pointed out, the 6800 series card has green checks for both so that means it's fully supported? But ... it's not listed on AMD's site?!
Bad docs are how you cement a reputation of "just buy nvidia and install their latest drivers and it'll be fine".
Removing support for Radeon VII is a bonehead move that smacks of stupidity or greed. The cards were targeted for enthusiast gamers but have enterprise level hardware, like HBM2 memory and 1 TB/s bandwidth.
I will provide this feedback to the docs team to clean up. I found it hard when i was making that Poll :D but I looked harder instead of trying to fix the docs. So thank you for the feedback.
