In the vast majority of cases it’s 60% or more even both at stock and both OC’d. In a lot of those videos it’s nearly touching 2x the performance at 1440p. A 1080Ti is some 40%+ over even a 1080. A 980Ti can do roughly 1300mhz with a decent cooler? 1080Ti can also do pretty much the same increase at 2-2.1ghz with a decent cooler.
