GeForce GTX 680 vs GeForce 940MX comparison

In our benchmarks, the GeForce GTX 680 beats the GeForce 940MX in gaming performance.

In our comparison, the GeForce GTX 680 has a slightly 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. 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 GTX 680 at 195 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 680 is faster than the GeForce 940MX.
