The AMD Radeon RX 6900 XT graphics card has once again been pushed to its limit and scored a record-breaking 3.3 GHz overclock. The overclock was achieved by team OGS from Greece on the PowerColor Radeon RX 6900 XT Ultimate graphics card.

The AMD Radeon RX 6900 XT custom variants have been receiving the Big Navi 21 XTXH upgrade for a while now. We have seen the ASUS ROG STRIX LC TOP, Sapphire TOXIC Extreme, PowerColor Red Devil / Liquid Devil Ultimate, and ASRock OC Formula variants getting the specific GPU variant so far. The Navi 21 XTXH isn't just a binned GPU with higher clocked speeds, it also opens up 4.00 GHz maximum clock limits allowing overclockers to hit record speeds with LN2 cooling.
