Radeon R9 280X vs Radeon RX 580X specs and performance

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

Our database shows that the Radeon RX 580X 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. In addition, the Radeon RX 580X also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 580X has significantly more memory with 8 GiB of memory compared to 3 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 580X has a slightly lower TDP at 185 W when compared to the Radeon R9 280X at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

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