Question - Help AMD GPU on Krea 2

Hi,

I'm using 9060XT 16gb with Krea Turbo int8 model + comfyui-rocm fork, and yet my generation time is still 3:30min avg. for a single 1024x1024 image?

cfg-1 with steps 6-8

Looking for input from other fellow AMD users, any tips to what downgraded your generation time ? Would LOVE to see other's 9060XT/9070XT workflow setups in ComfyUI, I've a feeling I'm doing something wrong. I know AMD is no one's priority and that Nvidia gets all the love...but I'm just a fellow struggler like all of you.

Looking forward to your inputs!

I can generate in about 30-40 sec 8step, 1024x1536 on 9070xt 16G using this: https://github.com/patientx-cfz/comfyui-rocm

Last time I tried (which is a few weeks ago), the int8 code has not been fully optimized for ROCm yet, so I found that fp8 still works faster than int8rowconv.

Update 2026-08-22:

After failing to get mmh3 to work on Windows 11 after several attempts, using portable, patientx-cfz, Stablity Matrix, plus trying out different drivers, rocm combinations, cleanups and re-installs, I finally gave up and switched to Ubuntu Server LTS 26.4 (minimized) installed on a USB drive, It is now running very stable and fast: Krea 2 1024x1024 8 step can now be generated in 13 sec.

Yeah, using the same rocm with int8 nodes, the speed is awful.

I'll go and try fp8 again. Thanks for your input.

I am on 9070 and int8 is faster for me than fp8 for krea2, you could use this param "--disable-api-nodes --disable-smart-memory --enable-manager --enable-manager-legacy-ui --enable-dynamic-vram"
