Radeon RX 580 vs GeForce 940MX comparison

For gaming, the Radeon RX 580 graphics card is better than the GeForce 940MX in our tests.

Our database shows that the Radeon RX 580 has a slightly 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 580 also has a slightly 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 580 at 185 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 580 is better than the GeForce 940MX.
