Iris Plus 655 vs Radeon RX 550 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 550 GPU is faster than the Iris Plus 655 in gaming.

Our database shows that the Radeon RX 550 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 Radeon RX 550 also has a slightly 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 550 at 50 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 550 over the Iris Plus 655.
