Iris 540 vs GeForce GTX 660M comparison

For gaming, the GeForce GTX 660M graphics card is better than the Iris 540 in our tests.

The GeForce GTX 660M 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 540 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 540 has a significantly lower TDP at 15 W when compared to the GeForce GTX 660M at 50 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 GTX 660M is faster than the Iris 540.
