Radeon RX 6600 vs Radeon RX 560 XT comparison

In our benchmarks, the Radeon RX 6600 beats the Radeon RX 560 XT in gaming performance.

Our database shows that the Radeon RX 6600 has a significantly 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 6600 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.

In addition, the Radeon RX 6600 has a slightly lower TDP at 132 W when compared to the Radeon RX 560 XT at 150 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 6600 is better than the Radeon RX 560 XT.
