Radeon R9 390X vs Iris Xe benchmarks

According to the hardwareDB Benchmark, the Iris Xe GPU is faster than the Radeon R9 390X in gaming.

The Radeon R9 390X 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. Despite this, the Iris Xe 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 Xe has a significantly lower TDP at 15 W when compared to the Radeon R9 390X at 275 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 Xe over the Radeon R9 390X.
