Iris Plus 655 vs GeForce GTX 780 specs and performance

In our benchmarks, the GeForce GTX 780 beats the Iris Plus 655 in gaming performance.

In our comparison, the GeForce GTX 780 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 Plus 655 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 Plus 655 has a significantly lower TDP at 15 W when compared to the GeForce GTX 780 at 250 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 780 is faster than the Iris Plus 655.
