Radeon RX 580 vs Radeon RX 6900 XT specs and performance

In our benchmarks, the Radeon RX 6900 XT beats the Radeon RX 580 in gaming performance.

The Radeon RX 6900 XT has a significantly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the Radeon RX 6900 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 6900 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 6900 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 terms of raw gaming performance in our GPU benchmark, the Radeon RX 6900 XT is better than the Radeon RX 580.
