Iris Plus 655 vs Radeon RX 6600 XT benchmarks

In our benchmarks, the Radeon RX 6600 XT beats the Iris Plus 655 in gaming performance.

The Radeon RX 6600 XT has a significantly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Radeon RX 6600 XT 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 Plus 655 has a significantly lower TDP at 15 W when compared to the Radeon RX 6600 XT at 160 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 Radeon RX 6600 XT over the Iris Plus 655.
