Radeon RX 580 vs Radeon RX 6800 XT specs and performance

For gaming, the Radeon RX 6800 XT graphics card is better than the Radeon RX 580 in our tests.

In our comparison, the Radeon RX 6800 XT 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 6800 XT also has a significantly 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 6800 XT has significantly more memory with 16 GiB of memory compared to 8 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 580 has a significantly lower TDP at 185 W when compared to the Radeon RX 6800 XT at 300 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 Radeon RX 6800 XT over the Radeon RX 580.
