AdoredTV has a pretty objective video on this subject[1]. TL;DW he expects it to move past Intel perf in the future - based on how an older AMD chip is now beating a then-better Intel chip.
My opinion: if Microsoft is able to pivot the Scorpio over to the Ryzen (or indeed, any CPU with more than 4C/8T) it will drastically alter the lowest common denominator in terms of what game developerss target - i.e. we'll see games moving towards more modern threading architectures (e.g. futures/jobs as-per Star Citizen, which more thoroughly exploit CPU resources).
Furthermore, there is hearsay evidence that supports AMDs claims. Ashes of the Singularity currently runs better on Intel but the developers claim:
[2]> Oxide games is incredibly excited with what we are seeing from the Ryzen CPU. Using our Nitrous game engine, we are working to scale our existing and future game title performance to take full advantage of Ryzen and its 8-core, 16-thread architecture, and the results thus far are impressive.
In addition to that, if you look at the CPU usage/saturation alongside the benchmarks (13:08 in [1]) it's strikingly obvious that the CPU is not the bottleneck - Intel is upwards of 90% on all cores while the Ryzen hovers around ~60%. I'm holding my credit card close until the aforementioned optimizations and rumored bios patches land, but I'm willing to give AMD a little benefit of the doubt - what we're seeing largely matches what they are saying.
