It's possible that the leaker found the core counts and GA10X-XXX numbers and has assumed that they are all RTX SKUs. The higher model could be a Quadro.
With the original Quadro RTX series models, Nvidia essentially used fully unlocked Geforce RTX silicon in a lot of cases. They were basically RTX Super before the super series released.
Nvidia would easily release the lower model for early binning reasons and have the 1070 Ti/Super series manoeuvre in their back pocket incase AMD has valid competition.
