Radeon RX 6600 XT vs Radeon RX 6900 XT comparison
In our benchmarks, the Radeon RX 6900 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. 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 6600 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 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 6600 XT has a significantly lower TDP at 160 W when compared to the Radeon RX 6900 XT at 300 W. Heat output doesn't match power consumption directly but, it's a good estimate.
According to the results of the hardwareDB benchmark utility, the Radeon RX 6900 XT is faster than the Radeon RX 6600 XT.
