I had a Titan X Pascal a little while ago in another machine. From what I'm seeing there are some gains with the Radeon VII, for example with Deus Ex heavily tweaked High settings (and with an OC) I can get 60fps+ with Radeon VII on 4K, while the Titan X Pascal was stuck around 50 - 55fps. Granted, this was when the game came out, on a totally different computer, but it's at least one title where VII runs marginally better (and even a 10% boost is key when going from 55fps to 60fps). Far Cry also seems a little better, but I don't recall the exact numbers. That said, in no way would this be worth upgrading to if you already have a Titan X Pascal. There are probably some gains but not enough to make it worth the trouble.
