Radeon RX 7900 XTX vs GeForce RTX 4090 Laptop benchmarks

In our benchmarks, the Radeon RX 7900 XTX beats the GeForce RTX 4090 Laptop in gaming performance.

Our database shows that the Radeon RX 7900 XTX 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 7900 XTX also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the GeForce RTX 4090 Laptop has a significantly lower TDP at 120 W when compared to the Radeon RX 7900 XTX at 355 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 7900 XTX is better than the GeForce RTX 4090 Laptop.
