GeForce RTX 2080 Ti vs Radeon RX 6900 XT benchmarks

For gaming, the Radeon RX 6900 XT graphics card is better than the GeForce RTX 2080 Ti in our tests.

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 significantly 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 significantly more memory with 16 GiB of memory compared to 11 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce RTX 2080 Ti has a slightly lower TDP at 250 W when compared to the Radeon RX 6900 XT at 300 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6900 XT is better than the GeForce RTX 2080 Ti.
