NVIDIA's new range of RTX Quadro cards is almost here, and the RTX (A)6000 may well be at the top of the pack. The 300 W card is expected to launch on October 5 with a GA102 GPU, 48 GB of GDDR6 VRAM and a new 8-pin power connector.

First few sentences it says 48GB then down a lil further says 46GB guessing it's the first one as 46GB seems odd for the Quadroe.
