Radeon RX 6800 XT vs GeForce RTX 4080 Laptop benchmarks

According to the hardwareDB Benchmark, the GeForce RTX 4080 Laptop GPU is faster than the Radeon RX 6800 XT in gaming.

In our comparison, the Radeon RX 6800 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 6800 XT also 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.

In addition, the GeForce RTX 4080 Laptop has a significantly lower TDP at 110 W when compared to the Radeon RX 6800 XT at 300 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 4080 Laptop is better than the Radeon RX 6800 XT.
