Which one will you choose and why, between R9700 32GB vs W7800 48GB?

Excerpt

I'm planning to upgrade my workstation (linux with 5700X/64GB DDR4) for local inference and pytorch training. I'm trying to decide between: 2× AMD Radeon AI PRO R9700 32GB 2× AMD Radeon PRO W7800 48GB I already have an RTX 3090 24GB , so the final system would have 3 GPUs . My motherboard has two PCIe 4.0 x8/x8 slots available for the two AMD GPUs. The RTX 3090 would have to move to a PCIe 3.0 x4 slot. My workload looks like: 1. Local GGUF inference : Mainly coding/reasoning models and multimoda
