Radeon RX 5700 XT vs Radeon RX 6600 XT comparison
In our benchmarks, the Radeon RX 5700 XT beats the Radeon RX 6600 XT in gaming performance.
Our database shows that the Radeon RX 6600 XT has a slightly 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 slightly 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. 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 6600 XT has a slightly lower TDP at 160 W when compared to the Radeon RX 5700 XT at 225 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 5700 XT over the Radeon RX 6600 XT.
