Both performance wise and feature wise. You should best talk to Fedora kernel graphics team about this - I believe Dave Airlie and Adam Jackson are the right contact people here. Also, is this something that should be configured on distro level? I'd assume that AMD kernel developers could switch the older cards to amdgpu by default any time they wanted, once they consider the support good enough. That's why it is currently hidden behind an experiemental kernel cmdline switch. I'm not clear whether distribution level override is in order there. But, I'm not super informed here and might be wrong. Kamil
