Radeon RX 6650 XT vs Radeon RX 7900 XT comparison

For gaming, the Radeon RX 7900 XT graphics card is better than the Radeon RX 6650 XT in our tests.

Our database shows that the Radeon RX 6650 XT has a slightly 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 6650 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, the Radeon RX 7900 XT has significantly more memory with 20 GiB of memory compared to 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6650 XT has a significantly lower TDP at 176 W when compared to the Radeon RX 7900 XT at 315 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 7900 XT over the Radeon RX 6650 XT.
