Rocm is kind of injury in general. Many people in the past have gotten burned by assuming that AMD would support some of their most popular and powerful new hardware, and then they just don't.
It seems like they're getting better at it, somewhat.
I have run two 6** level cards on both windows and Linux just fine. These cards have the same llvm target (gfx1030). It taps into ROCM for inferencing just fine.
So whatever you are saying is categorically a lie or a misunderstanding. To be frank, it is particularly terrible misinformation because you can get a 4070 16gb equivalent from AMD for less than $400.
7** series has RDNA3, but that doesn’t preclude prior cards from providing ROCM support. The 6800 with RDNA2 has way better specs. People need to do their own research.
Edit:
You can run two 6800s for less than $800 and have 32gb of VRAM at 4070 specs.
Yeah, AMD. They're providing the misinformation by not updating those pages. I use an rx 6800 on Linux just fine with rocm, but the compatibility page only lists it as compatible on Windows, not on Linux. AMD needs to make sure their docs are up to date.
They are trying their best to lose the current generation to no one. It's pretty funny when your own engineers can't get access to the cards you've supposedly launched.
