Radeon RX 550X vs Radeon RX 580 2048SP benchmarks

In our benchmarks, the Radeon RX 580 2048SP beats the Radeon RX 550X in gaming performance.

The Radeon RX 580 2048SP 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. Despite this, the Radeon RX 550X 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 Radeon RX 550X has a significantly lower TDP at 50 W when compared to the Radeon RX 580 2048SP at 150 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 580 2048SP is better than the Radeon RX 550X.
