GeForce GTX 1080 vs Radeon RX 6600 XT comparison
In our benchmarks, the Radeon RX 6600 XT beats the GeForce GTX 1080 in gaming performance.
In our comparison, 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 significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.
Next up, in terms of GPU memory, they both have the same amount of memory at 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 slightly lower TDP at 160 W when compared to the GeForce GTX 1080 at 180 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 1080.
