More rumors have emerged on AMD's RDNA 2 "Navi 2X" GPUs which will be powering the next-gen Radeon RX line of graphics cards. The rumor once again suggests a late Q4 2020 launch & also talks about RDNA 3 and how it aims to be one of the biggest revolution for GPUs by the time it launches.

The rumored information comes from AquariusZi (via @davideneco) who is a well-known name in the tech scene at the PTT forums. The user was the first to list down expected die sizes of AMD's RDNA 2 GPUs and has now shed some more light on what we can expect from the upcoming Navi 2X line of GPUs for next-generation Radeon RX graphics cards.
