Iris Plus 655 vs Radeon RX 540 specs and performance

For gaming, the Radeon RX 540 graphics card is better than the Iris Plus 655 in our tests.

In our comparison, the Radeon RX 540 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 540 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 conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 540 over the Iris Plus 655.
