Radeon RX 6500 XT vs Radeon RX 7900 XT specs and performance

For gaming, the Radeon RX 7900 XT graphics card is better than the Radeon RX 6500 XT in our tests.

In our comparison, the Radeon RX 6500 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 6500 XT also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

As stated by the manufacturer, the Radeon RX 7900 XT has significantly more memory with 20 GiB of memory compared to 4 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6500 XT has a significantly lower TDP at 107 W when compared to the Radeon RX 7900 XT at 315 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 7900 XT over the Radeon RX 6500 XT.
