GeForce RTX 2080 vs Radeon RX 6600 XT benchmarks

For gaming, the GeForce RTX 2080 graphics card is better than the Radeon RX 6600 XT in our tests.

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 significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Furthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6600 XT has a significantly lower TDP at 160 W when compared to the GeForce RTX 2080 at 250 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 2080 is better than the Radeon RX 6600 XT.
