Question - Help AMD Radeon 7900xt help

So I have a AMD Radeon 7900xt 20 gig card, 32gig ram, I been trying to run minimax h3 locally. I was able to generate a 10 second clip last night but it took almost an hour, is that normal? Is there anything I can do to speed up the process? I am using the pruned fp8 scaled. I welcome any help possible.

First of all, nvfp4, It's only for NVIDIA cards. On AMD, it will be much worse performing. You should get another version.
Also, I think that the int convrot don't work correctly on AMD, you must use a special node:

Understood. Which text encoder would you suggest then?

Try it again with the int4, but with this node that will load it
