Battlefield 1, Mafia III, Gears of War 4, Titanfall 2
Battlefield 1 was tested on the outskirts of an active a 64-player map, it's a little easier to replicate the results here. Anyway the 7700K was again clearly faster, the margins weren't huge but the quad-core always served up the best results.
Once upon a time, Mafia III murdered quad-cores like a ruthless gangster. These days it's happy to get along with all types of CPUs. In fact it's now more favorable when it comes to quad-cores and like most games prefers those MHz.
Gears of War 4 throws up more unexpected results, here the 7700K was 20% faster when comparing the minimum frame rate and 16% faster once both CPUs are overclocked. Another clear win here for the aging quad-core.
Titanfall 2 has never given us anything other than GPU bound results and here nothing changes, both CPUs pushed the GTX 1080 Ti to in excess of 130fps at all times.
