GeForce GTX 660 Ti vs Iris Xe comparison

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

The GeForce GTX 660 Ti 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 Xe 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 Xe has a significantly lower TDP at 15 W when compared to the GeForce GTX 660 Ti at 150 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 660 Ti is better than the Iris Xe.
