Users in the Chiphell community have discovered the BIOS for AMD's upcoming Radeon RX 6950 XT, confirming that it uses the Navi 21 KXTX GPU. The AMD Navi 21 KXTX GPU is another variation of the Navi 21 chip which should be similar to the XTXH variant. The XTXH SKU is the premium bin of the AMD RDNA2 'Navi 21' GPU, offering up to 10% increased clock speeds than the company's standard Navi 21 XT GPU.

TechPowerUP removed the BIOS information reasonably quickly from their BIOS collection database. Still, Chiphell managed to grab these BIOS quickly, allowing us to have a greater understanding of the higher TGP, the supported memory types, and the power limits of the AMD Navi 21 KXTX GPUs powering the Radeon RX 6950 XT graphics card.
