Radeon R9 280X vs Radeon RX 580 2048SP benchmarks

In our benchmarks, the Radeon R9 280X beats the Radeon RX 580 2048SP in gaming performance.

In our comparison, 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. In addition, the Radeon RX 580 2048SP also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Radeon RX 580 2048SP has a significantly lower TDP at 150 W when compared to the Radeon R9 280X at 250 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Radeon R9 280X is faster than the Radeon RX 580 2048SP.
