Your links are to far cry primal not prey. Here is the only one I have found but its on a questionable site.
If your benchmark graph is to be believed, the AMD system appears to perform better than the Intel system, which doesn't exactly help the narrative that Ryzen should be skipped for pure gaming systems.
The review is incomplete.
While it's true to say that Ryzen isn't in a lot of systems yet, as it's too new, Ryzen is something a lot of people are looking at purchasing. Reviews shouldn't just be for what people currently have, but also should include what people are shopping for. People look at reviews to help with product choices. Leaving Ryzen out of the review here seems to promote a level of disservice to consumers.
