ASRock has finally unleashed its flagship AMD graphics card, the Radeon RX 6900 XT OC Formula. This is the first time that the OC Formula brand has landed on ASRock's graphics cards lineup and it's done so in a grand way by fusing in with AMD's Big Navi GPU.

The ASRock Radeon RX 6900 XT is a beast of a card featuring the full-fat Big Navi 21 XTXH GPU. The GPU runs at blistering fast clock speeds of up to 2295 MHz Game and 2475 MHz boost, making this the fastest Big Navi custom design to date. For users who want a silent operation, the card also has a silent mode (Q BIOS) which lets the card run at a more conservative 2165 MHz Game & 2365 MHz boost clock. The card retains its 16 GB GDDR6 memory which operates across a 256-bit wide bus & also features 128 MB of Infinity Cache onboard the GPU.
