Adequacy of AMD Ryzen 5900X 12 Core 32GB RAM plus NVIDIA GeForce RTX 3080 10GB Gigapixel AI?

Are AMD systems appropriate for Topaz AI products?

I wish to replace my 2017 iMac with 64 GB RAM. It is very slow when using Gigapixel AI. Am I limited to Intel processors for adequate Topaz AI performance?

I run AMD CPU/GPU and the Topaz apps run fine in terms of performance, although I don’t utilize GigaPixel.
