Head-to-head Dota 2 7.41e win rate from ranked matches.
In Dota 2 7.41e, Chaos Knight wins the Chaos Knight vs Viper matchup: Chaos Knight beats Viper in 56.66% of 593 ranked matches.
Getting pulled in by Reality Rift is a death sentence for Viper. His entire kit is built to kite and wear down a single hero, but Chaos Knight brings an army. Phantasm illusions are a massive problem, as Viper lacks the area-of-effect damage to clear them and can easily waste his ultimate on a fake. Even landing Nethertoxin to break Chaos Knight's passive isn't a guaranteed solution, as CK can often pull him out of the pool or wait out the effect. To be fair, we haven't seen this lane played out much recently.
