GeForce GTX 980 Ti vs Radeon RX 6600 XT specs and performance

For gaming, the Radeon RX 6600 XT graphics card is better than the GeForce GTX 980 Ti in our tests.

In our comparison, the Radeon RX 6600 XT has a significantly 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 significantly 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.

Next up, in terms of GPU memory, the Radeon RX 6600 XT has slightly more memory with 8 GiB of memory compared to 6 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6600 XT has a significantly lower TDP at 160 W when compared to the GeForce GTX 980 Ti at 250 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 6600 XT is faster than the GeForce GTX 980 Ti.
