There is no option for RX 5600 XT on the hardware choices, even though it got RX 5500 XT, RX 5700 and RX 5700 XT, why?
The RX 5600 XT is missing simply because the hardware list isn’t exhaustive — HF only added the GPUs that appeared in user benchmarks or internal tests. The 5600 XT sits between the 5500 XT and 5700 series, so it wasn’t included by default.
Your request makes sense: it’s a valid RDNA2 card and adding it would help users get accurate Fit Finder results. Once the team updates the hardware table, it should appear like the other RX 5000 series models.
Actually, RX 5600 XT is RDNA1 family with the same target as RX 5700/RX 5700 XT (gfx1010), it is not part of the RDNA2 family.
Anyways, my current workaround is to use RTX 2060 which has similar raw compute power and 6GB VRAM, but it would be inaccurate as it would assume CUDA support, which my card doesn’t have.
