Iris Plus 655 vs Radeon R5 340 benchmarks

According to the hardwareDB Benchmark, the Iris Plus 655 GPU is faster than the Radeon R5 340 in gaming.

In our comparison, the Radeon R5 340 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. Despite this, the Iris Plus 655 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 R5 340 at 65 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 Iris Plus 655 over the Radeon R5 340.
