TechPowerUp notes these may be Ampere-based GPUs and points out that the entries data back to October and November. NVIDIA is expected to show off Ampere at its GPU Technology Conference from March 22nd to March 26th.
Some things to note are weird memory configurations in both models like 24 GB for the more powerful model and 47 GB (which should be 48 GB) for the weaker one. The results are not the latest, as they date back to October and November, so it may be that engineering samples are in question and the clock speed and memory configuration might change until the launch happens.
