An unreleased GPU that is allegedly based on AMD's next-generation 'Radeon RX' Navi GPU architecture has leaked out by Twitter user CyberPunkCat who claims have sources over at SK Hynix who provided him with an info sheet listing down the specifications for this new 2020 flagship design.

We know from previous reports that AMD has already promised us both, a next-generation 7nm+ Navi & a 7nm refresh lineup of Radeon RX graphics cards in 2020. The 7nm refresh lineup would be replacing the existing graphics cards with a more fine-tuned design while enthusiasts would be really looking forward to the 7nm+ lineup of GPUs which is reportedly going to include the much-awaited 'Big Navi' chip.
