It looks like AMD's high-end Radeon RX Navi 21 GPU specifications have started to leak out with reports from the Far East claiming that the next-generation GPU could be twice as fast as Navi 10. According to the folks over at Chinese PTT forums, a high-end Navi GPU has been taped out and is headed to launch next year in 2020.

The details were posted by a Chinese Forum member who lists down several key specifications of the upcoming high-end Navi GPU. We know that AMD's current Radeon RX lineup is based on the 7nm process node and is part of the first generation RDNA family. The 2nd generation RDNA family is expected to make use of the advanced 7nm+ process node which should offer leverages in the overall performance efficiency while offering, even more, denser designs to be made possible.
