Radeon RX 580X vs Radeon RX 590 benchmarks

In our benchmarks, the Radeon RX 590 beats the Radeon RX 580X in gaming performance.

The Radeon RX 590 has a slightly 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 590 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.

Next up, in terms of GPU memory, they both have the same amount of memory at 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 590 has a slightly lower TDP at 175 W when compared to the Radeon RX 580X at 185 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 terms of raw gaming performance in our GPU benchmark, the Radeon RX 590 is better than the Radeon RX 580X.
