Radeon RX 7900 XTX vs GeForce RTX 4080 Laptop specs and performance

According to the hardwareDB Benchmark, the Radeon RX 7900 XTX GPU is faster than the GeForce RTX 4080 Laptop in gaming.

The Radeon RX 7900 XTX 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 7900 XTX also has a significantly 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 7900 XTX at 355 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 Radeon RX 7900 XTX is better than the GeForce RTX 4080 Laptop.
