Iris 6100 vs GeForce GTX 660M comparison

In our benchmarks, the GeForce GTX 660M beats the Iris 6100 in gaming performance.

In our comparison, the GeForce GTX 660M 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 6100 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 6100 has a significantly lower TDP at 15 W when compared to the GeForce GTX 660M at 50 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 660M is faster than the Iris 6100.
