GeForce RTX 3080 Ti vs Radeon RX 6900 XT specs and performance
According to the hardwareDB Benchmark, the Radeon RX 6900 XT GPU is faster than the GeForce RTX 3080 Ti in gaming.
Our database shows that the Radeon RX 6900 XT has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Radeon RX 6900 XT also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.
Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6900 XT has slightly more memory with 16 GiB of memory compared to 12 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.
In addition, the Radeon RX 6900 XT has a slightly lower TDP at 300 W when compared to the GeForce RTX 3080 Ti at 350 W. Heat output doesn't match power consumption directly but, it's a good estimate.
In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6900 XT is better than the GeForce RTX 3080 Ti.
