The specifications for AMD's Radeon RX 6000 series graphics cards have reportedly been confirmed by Rogame. According to his information, AMD's next-generation RDNA 2 (Navi 2X) lineup of GPUs would initially feature two chips with vastly different memory configurations.

In his tweet, Rogame says that he has confirmed the memory configurations of at least two Navi 2X GPUs based on the RDNA 2 architecture. These GPUs include the Navi 21 and Navi 22. AMD's Navi 21 is based around the "Big Navi" GPU design which will power the flagship variants in the Radeon RX 6000 series lineup while the Navi 22 GPUs will power the high-performance lineup around the $500 US price range.
