Radeon RX 6600 XT vs GeForce RTX 3080 Laptop benchmarks

For gaming, the GeForce RTX 3080 Laptop graphics card is better than the Radeon RX 6600 XT in our tests.

In our comparison, the Radeon RX 6600 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 6600 XT also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the GeForce RTX 3080 Laptop has a slightly lower TDP at 115 W when compared to the Radeon RX 6600 XT at 160 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 3080 Laptop is better than the Radeon RX 6600 XT.
