Iris Plus 640 vs GeForce 920MX comparison

In our benchmarks, the Iris Plus 640 beats the GeForce 920MX in gaming performance.

Our database shows that the GeForce 920MX 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. Despite this, the Iris Plus 640 has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the Iris Plus 640 has a slightly lower TDP at 15 W when compared to the GeForce 920MX at 16 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the Iris Plus 640 is better than the GeForce 920MX.
