GeForce GTX 1660 vs Iris Plus 655 comparison

For gaming, the GeForce GTX 1660 graphics card is better than the Iris Plus 655 in our tests.

Our database shows that the GeForce GTX 1660 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. In addition, the GeForce GTX 1660 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Iris Plus 655 has a significantly lower TDP at 15 W when compared to the GeForce GTX 1660 at 120 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 1660 is faster than the Iris Plus 655.
