Looking at the slide Nvidia compares the performance jump between GTX 10 series and the RTX 20 series as being similar to the performance leap when moving between the GTX 9 and GTX 10 series', a significant performance uptick even without the use of RTX features like Ray Tracing and DLSS (Deep Learning Super Sampling. The only issue here is that Nvidia's new 20 series products also ship with significantly higher MSRPs than it's predecessors, a fact that is not considered in this performance-centric graph.
