Radeon RX 6600 XT vs GeForce GTX 980M comparison

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

Our database shows that 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 maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the Radeon RX 6600 XT has significantly more memory with 8 GiB of memory compared to 4 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 GeForce GTX 980M has a significantly lower TDP at 100 W when compared to the Radeon RX 6600 XT at 160 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6600 XT is faster than the GeForce GTX 980M.
