Radeon RX 580 vs Radeon RX 6600 XT comparison

In our benchmarks, the Radeon RX 6600 XT beats the Radeon RX 580 in gaming performance.

The Radeon RX 6600 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 6600 XT also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, they both have the same amount of memory at 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6600 XT has a slightly lower TDP at 160 W when compared to the Radeon RX 580 at 185 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6600 XT over the Radeon RX 580.
