GeForce 940MX vs GeForce 840M specs and performance

In our benchmarks, the GeForce 840M beats the GeForce 940MX in gaming performance.

In our comparison, the GeForce 840M 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. Despite this, the GeForce 940MX has a slightly 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 GeForce 840M at 33 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the GeForce 840M is faster than the GeForce 940MX.
