I watched some GPU tests the other day and 7.9TF 5700 was on average ~10% better performer then Vega 64. So I think something like XT with more BW would be therbouts with Radeon 7, let alone Vega 64.Then you're in luck, since 9.2TF of RDNA will outperform 12TF of GCN in everything but compute.
I'd prefer 12 RDNA TF's, personally. Heck, I'd prefer 20. But the GitHub leaks are the most credible we've seen so far, and point to a console that can slap about a Vega 64.
