I thought I would share my experience this evening with the group here seeing that I still excited as hell for getting this hodgepodge to work at all.

I have been playing with the machineMl version of stable diffusion on Windows for a while now (we won't go into the reasons why, but I have the 6800XT, which is not well suited to this use case)

Automatic11111 on MachineML is dog slow, but I got some interesting results. So today I cleared out an old SSD, wired it up and installed a clean ubuntu. Following this guide I managed to get rocM running and the difference is like chalk and cheese. Or rather Impulse and Warp drive. Totally crazy!

So for you AMD Radeon users out there. There is hope. It is in Linux, but it is there.

I am on Windows, automatic1111 with directML and rendering is pretty fast. 7700x, 6750xt and 32GB at 4800mhz and a couple of m.2 drives. No xformers tho and some problems when upscaling in txt2image, but it renders prompts with default settings in 10 to 15 seconds. Fast enough for me. AMD has updated their Adrenalin drivers lately to have better directML performance.

Some things can take some time or aren't supported on AMD, but it's surely faster then my rtx 1070 and 1080 rigs wich performed adequately, except with training.

For sure. It works, especially if you use Shark with the experimental driver, but the speed difference was an order of magnitude for the rocm compiled driver on linux. I am already needing more card though. The 6800xt 16gb ram is not enough.I am running on medium ram settings. I hear rocm support for windows is coming soon, so that will be interesting as well. There were some rumours earlier this year.
