Iris Plus 640 vs GeForce 940MX benchmarks

For gaming, the Iris Plus 640 graphics card is better than the GeForce 940MX in our tests.

The GeForce 940MX 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 GeForce 940MX also 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 Iris Plus 640 has a significantly lower TDP at 15 W when compared to the GeForce 940MX at 23 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 Iris Plus 640 is better than the GeForce 940MX.
