Lies? No. But you can manipulate the outcome with the green bars going sky high, sure. These benchmarks often isolate certain scenarios and highlight them. Both nVidia and AMD have been doing it for years. In this case it’s the 4k resolution with AA cranked up. Not a common use scenario, is it?
Besides, the benchmark is silly, what is this scale from 0 to 2.5? Performance units? Based on what?
Hear my prediction. Judging by the specs and architectural improvements, it’s going to be an extra 20-25% of raw oomphs (my own performance unit 
when going from 1080 to 2080. That’s enough to convince me as an owner of an older generation GPU. Somehow I feel 1080 owners will stay reluctant.
Anyway, it’s the feasibility of the RT tech that’s I’m more curious about - that’s why I poked you. Just wondering how this will change the work pipeline taking into account what raytracing does to shadows and reflections.
