PowerColor's Radeon RX 6900 XT Red Devil Ultimate with AMD's Big Navi 21 XTXH has achieved the GPU frequency world record. The GPU was pushed to an incredible 3.2 GHz by famous overclocker, Der8auer, who pushed the card to its limit using LN2 cooling.

The AMD Radeon RX 6900 XT featuring the Big Navi 21 XTX GPU is the flagship offering from the red team but during its launch, overclockers were disappointed to find that AMD had set a GPU clock limit of around 2.8-3.0 GHz for its flagship chips. Only just recently, AMD started shipping its higher-binned Navi 21 XTXH GPUs to AIBs and we have since seen several new variants come up such as PowerColor's Radeon RX 6900 XT Red Devil & Liquid Devil Ultimate and ASRock's Radeon RX 6900 XT OC Formula.
