AMD's flagship Navi GPU or 'Big Navi' as the red team themselves refer to it as has been under-development for a while now and upon release, it will go on to power next-generation Radeon RX graphics cards with a sole focus on the 4K gaming segment.

There aren't many details on the big Navi GPU available at the moment but during the Radeon RX 5600 XT's press briefing, AMD's Radeon Product Management Lead, Mithun Chandrasekhar, spilled the beans that like Ryzen, Big Navi is going to disrupt the 4K gaming segment.
