Radeon RX 6900 XT vs GeForce RTX 3090 Ti comparison

For gaming, the GeForce RTX 3090 Ti graphics card is better than the Radeon RX 6900 XT in our tests.

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. 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.

As stated by the manufacturer, the GeForce RTX 3090 Ti has significantly more memory with 24 GiB of memory compared to 16 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 6900 XT has a significantly lower TDP at 300 W when compared to the GeForce RTX 3090 Ti at 450 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 3090 Ti over the Radeon RX 6900 XT.
