For Honor, Ghost Recon, Mass Effect, Dawn of War III
Although For Honor is mostly a GPU-bound game and all three CPUs are able to deliver around the same average frame rate, there is some variance when looking at the minimum. What's really interesting here is that the R5 1600 actually beats not just the 7800X but also the 7700K, when stock and overclocked. This is a curious result indeed, especially in a title where the CPU isn't that heavily taxed.
Tom Clancy's Ghost Recon Wildlands is another GPU-limited game for the most part. The R5 1600 and 7800X delivered similar performance and here we see that the 7700K isn't a great deal faster.
Mass Effect: Andromeda is a game that's played well with Ryzen since day one and that's still true after many updates. Overclocked, the R5 1600 is able to get the most out of the GTX 1080 Ti and here it matched the 7800X and 7700K.
Dawn of War III was patched sometime in July and the hotfix update completely crippled performance in this title, reducing the 1080 Ti to around 50fps. I've had to use the previous version of the game to add the Ryzen 5 results -- please don't ask how I managed to do that. The R5 1600 is able to match the 7800X in Dawn of War III, so some very competitive performance here indeed.
