GeForce GTX 1080 Ti vs Radeon RX 6900 XT benchmarks

In our benchmarks, the Radeon RX 6900 XT beats the GeForce GTX 1080 Ti in gaming performance.

In our comparison, 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. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6900 XT has significantly more memory with 16 GiB of memory compared to 11 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 1080 Ti has a slightly lower TDP at 250 W when compared to the Radeon RX 6900 XT at 300 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 GTX 1080 Ti.
