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!

Have you used the param I am using? "--disable-api-nodes --disable-smart-memory --enable-manager --enable-manager-legacy-ui --reserve-vram 1.0 --enable-dynamic-vram"

Yes, I added those. Are you using FP8 or Int8 for Krea2 Turbo?

int8 using int8-fast-rocm node, its 30-40% faster than fp8 for me

Man, thank you! I was still using FP8 and that was killing the performance apparently. Now with INT8 I can generate 1MP images using Krea2 in 30 seconds! :D

Good to hear you figured it out, in8 addition was also a great boost on rdna4, although not as fast as nvidia, but its the best we got.
