GeForce GTX 660 vs Iris Xe benchmarks

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

In our comparison, 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 has a slightly 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 660 at 140 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Iris Xe is faster than the GeForce GTX 660.
