Radeon RX 6600 XT vs GeForce 940MX benchmarks

In our benchmarks, the Radeon RX 6600 XT beats the GeForce 940MX in gaming performance.

Our database shows that the Radeon RX 6600 XT has a significantly 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 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 940MX has a significantly lower TDP at 23 W when compared to the Radeon RX 6600 XT at 160 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 Radeon RX 6600 XT is better than the GeForce 940MX.
