Users in the Chiphell community were quick to find the BIOS for AMD’s upcoming Radeon RX 6950 XT, confirming that it uses the Navi 21 KXTX GPU in the TechPowerUP database. Chiphell community already confirms higher TGP capacities for RX 6950XT SKU, power limits, and the supported memory types of the AMD Navi 21 KXTX GPUs powering the Radeon RX 6950 XT graphics card. The AMD Navi 21 KXTX GPU is another interpretation of the Navi 21 chip which should be identical to the XTXH variant. The XTXH SKU is the premium bin of the AMD RDNA2 ‘Navi 21’ GPU, offering up to 10% more boosted clock speeds compared to the company’s standard Navi 21 XT GPU.
Two of the cards listed there were MSI RX 6950 XT GAMING X TRIO GPU (on the left) and the SAPPHIRE RX 6950 XT NITRO+ Pure graphics card. Before TechPowerUP removed the information from the site website VideoCardz was able to grab the screenshot of the information.
The latter has a power limit set to 325W it can additionally be modified by 20%, which means it can reach up to 400W of power. The MSI RX 6950 XT GAMING X TRIO graphics card delivers a 332W TGP with an expansion of 12%, which is a total of 372W power consumption. On the other hand SAPPHIRE’s RX 6950 XT NITRO+ Pure GPU has a power limit of 325W that can be increased even higher by 20%, allowing the GPU to achieve a TGP of 390W.
As previously rumored that the newest RX 6950XT SKU would use XTXH GPU technology, but that is not true the RX 6950XT model will ship with the latest Navi 21 KXTX GPU. This means that AMD is adding a fourth variation to the Navi 21 GPU series, which adds to the company’s consumer Radeon lines. Currently, it is unknown whether AMD will flash the KXTX codename over XT or XTXH variants, but it is speculated that they will not. Because the BIOS only supports 18 Gbps memory from HYNIX and Samsung. So by limiting the series to Navi 21 KXTX GPU technology, they can avoid the limited support of HYNIX and Samsung memory, which only allows 18 Gbps memory.
