Radeon RX 6650 XT vs GeForce RTX 4090 Laptop comparison

In our benchmarks, the GeForce RTX 4090 Laptop beats the Radeon RX 6650 XT in gaming performance.

In our comparison, the Radeon RX 6650 XT 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 6650 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.

In addition, the GeForce RTX 4090 Laptop has a significantly lower TDP at 120 W when compared to the Radeon RX 6650 XT at 176 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 GeForce RTX 4090 Laptop is better than the Radeon RX 6650 XT.
