Radeon RX 6700 XT vs Radeon RX 7900 XTX benchmarks

In our benchmarks, the Radeon RX 7900 XTX beats the Radeon RX 6700 XT in gaming performance.

In our comparison, the Radeon RX 6700 XT has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the Radeon RX 6700 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.

As stated by the manufacturer, the Radeon RX 7900 XTX has significantly more memory with 24 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 6700 XT has a significantly lower TDP at 230 W when compared to the Radeon RX 7900 XTX at 355 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 7900 XTX is better than the Radeon RX 6700 XT.
