GeForce RTX 4090 Laptop vs Radeon RX 7800 XT specs and performance

For gaming, the Radeon RX 7800 XT graphics card is better than the GeForce RTX 4090 Laptop in our tests.

In our comparison, the Radeon RX 7800 XT 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. In addition, the Radeon RX 7800 XT 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 4090 Laptop has a significantly lower TDP at 120 W when compared to the Radeon RX 7800 XT at 263 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 7800 XT is better than the GeForce RTX 4090 Laptop.
