AMD Radeon RX 6900 XT benchmarks show that it is not as good as the Nvidia RTX 3090 graphics card but AMD Radeon RX 6900 XT consumes less than power than RTX 3090 GPU.
Another thing to note is that AMD Radeon RX 6900 XT has 300W TDP but for some reason, AMD has capped it to 255W. The only way to use AMD Radeon RX 6900 XT to its full potential is by overclocking it to 300W.
Infact, when unlocked the AMD Radeon RX 6900 XT can run at 2720MHz without any issues and it can even overtake RTX 3090 while playing games at 4k resolution.
Here is the benchmark chart that shows how AMD Radeon RX 6900 XT fares against other popular graphics cards.
AMD Radeon RX 6900 XT benchmarks indicate that when compared to AMD Radeon RX 6800 XT, 6900XT offers 6% advantage at 2K resolution while using AMD Radeon RX 6900 XT at 4K resolution gives lead of 7%.
However, temperature performance of AMD Radeon RX 6900 XT is same as 6800XT and that is around 80 degrees. We really hope that AMD makes use of RDNA3 GPU in upcoming generations.
