Iris Plus 655 vs Radeon RX 560X benchmarks

In our benchmarks, the Radeon RX 560X beats the Iris Plus 655 in gaming performance.

The Radeon RX 560X 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 560X also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the Iris Plus 655 has a significantly lower TDP at 15 W when compared to the Radeon RX 560X at 75 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 Radeon RX 560X is faster than the Iris Plus 655.
