Radeon RX 6600 XT vs GeForce RTX 4080 benchmarks

In our benchmarks, the GeForce RTX 4080 beats the Radeon RX 6600 XT in gaming performance.

In our comparison, the GeForce RTX 4080 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. Despite this, the Radeon RX 6600 XT 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 GeForce RTX 4080 has significantly more memory with 16 GiB of memory compared to 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 4080 at 420 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 4080 is better than the Radeon RX 6600 XT.
