Iris Plus 640 vs GeForce 940M comparison

In our benchmarks, the GeForce 940M beats the Iris Plus 640 in gaming performance.

Our database shows that the GeForce 940M has a significantly 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 Iris Plus 640 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 940M at 75 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 940M is faster than the Iris Plus 640.
