Mirror's Edge, Mafia III, Gears of War, Deus Ex
For some reason, in Mirror's Edge Catalyst the Ryzen CPUs hit a bit of a wall, albeit at well over 100fps. Whereas the 6900K averaged 146fps, the 1800X and 1700X were limited to a 138fps average (only 5% slower).
Moving to 1440p, the results tighten up as Ryzen can pretty much get the most out of a Titan XP at 1440p in Mirror's Edge Catalyst, scoring just 2% slower than the 6900K while matching its minimum frame rate.
Mafia III has some interesting figures for us and Ryzen kicks some serious silicon here. This is also one of the few games where you'll see Broadwell-E smoking Kaby Lake.
The 1800X is right in the thick of it, matching the 5960X and tailing the 6900K by a slim margin -- and these are the 1080p results. It's also interesting to note that disabling SMT actually hurts performance as the 1800X becomes 7% slower.
Things get even more interesting at 1440p. Here the 1800X takes the top spot, granted at just 1fps ahead of the 6900K and 5960X, which is well within the margin of error, but great to see regardless. Again, disabling SMT hurts performance by quite a bit in Mafia III.
Disabling SMT in Gears of War 4 improved the minimum frame rate slightly while bringing even bigger gains for the average fps.
Ryzen looks about 'average' when playing this title at 1080p, trailing the 5960X and struggling to match the minimum frame rate of the 7600K.
Ryzen looks more competitive at 1440p and while the average frame rate is a bit slower than you might have hoped for, the minimum is still strong.
AMD's chips look lost in Deus Ex: Mankind Divided as both the 1800X and 1700X fell well behind the 5960X. Fortunately, disabling SMT significantly boosts the average frame rate in this title, though oddly the minimum remains much the same.
Not a great showing for Ryzen in this DirectX 12 title at 1080p, which is particularly strange strange given how closely AMD worked with the developer. Obviously AMD focused on optimizations of Polaris but you thought they might revisit the game for Ryzen.
In any case, upping the resolution to 1440p produces a GPU bottleneck and now Ryzen looks rather impressive. Disabling SMT had no impact on performance here.
