AMD showed off a sneak preview of the upcoming Radeon RX 6000 series Big Navi's gaming performance in Borderlands 3, CoD: Modern Warfare, and Gears 5. The RX 6000 was paired with a Ryzen 9 5900X, but comparisons with available RTX 3080 benchmarks show that AMD is within striking distance in these titles and if priced right, may end with potential success.

There's no clear indication as to whether this is "Big" Navi or any of the other variants - all we know is it's a 6000 series.
I personally feel it would be odd for them to lead with a teaser that sort-of matches the 3080 and then reveal it to be top of their pile, but who knows. Looking forwards to the announcement, either way.
