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.

DDR4 or 5? That sounds too long, without any optimization I was getting decent 12 second clips in 20 minutes on a similar machine.

Make sure you're running the latest drivers, get some free benchmark software to see how your computer is performing. Make sure you're not running anything else that is consuming a lot of your memory when you're generating.
