GeForce GTX 660 vs Iris Xe MAX comparison

According to the hardwareDB Benchmark, the GeForce GTX 660 GPU is faster than the Iris Xe MAX in gaming.

Our database shows that the GeForce GTX 660 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 Xe MAX 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 MAX has a significantly lower TDP at 25 W when compared to the GeForce GTX 660 at 140 W. Heat output doesn't match power consumption directly but, it's a good estimate.

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