Radeon R5 340 vs GeForce 940MX comparison

In our benchmarks, the GeForce 940MX beats the Radeon R5 340 in gaming performance.

The GeForce 940MX 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 GeForce 940MX 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 940MX has a significantly lower TDP at 23 W when compared to the Radeon R5 340 at 65 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 940MX is better than the Radeon R5 340.
