Radeon RX 6600M vs GeForce RTX 3080 Laptop comparison

In our benchmarks, the GeForce RTX 3080 Laptop beats the Radeon RX 6600M in gaming performance.

Our database shows that the Radeon RX 6600M 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 6600M also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Radeon RX 6600M has a slightly lower TDP at 100 W when compared to the GeForce RTX 3080 Laptop at 115 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 3080 Laptop is better than the Radeon RX 6600M.
