GeForce GTX 1080 vs Iris Xe benchmarks

For gaming, the GeForce GTX 1080 graphics card is better than the Iris Xe in our tests.

The GeForce GTX 1080 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 1080 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 Xe has a significantly lower TDP at 15 W when compared to the GeForce GTX 1080 at 180 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 1080 over the Iris Xe.
