16 April 2021, 2:55 am EDT By Asrock just launched a brand new RX 6900 XT in their lineup: the Radeon RX 6900 XT OC Formula 16 GB. This is considered Asrock's fastest air-cooled GPU to date, which features AMD's current-gen Big Navi 21 XTXH behemoth with an obvious focus on overclocking, reports TweakTown.

But still, it's always fun to talk about how amazing the gaming performance will be on this custom-cooled card. Insane Hardware Under The Hood You'll never run out of VRAM anytime soon with its frankly unnecessary 16GB of fast GDDR6 memory, though that 256-bit memory bus is a little suspect. Despite that, however, the card can boost to almost 2.5 GHz due to its insane 21-phase VRM, which helps keep the card stable, according to Tom's Hardware. There's also 128 MB of AMD's patented Infinity Cache on the card.
