GeForce GTX 960 vs Iris Plus 655 comparison

For gaming, the GeForce GTX 960 graphics card is better than the Iris Plus 655 in our tests.

Our database shows that the GeForce GTX 960 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. In addition, the GeForce GTX 960 also has a slightly 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 960 at 120 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 960 is faster than the Iris Plus 655.
