Radeon RX 6950 XT vs GeForce RTX 4090 Laptop specs and performance

For gaming, the GeForce RTX 4090 Laptop graphics card is better than the Radeon RX 6950 XT in our tests.

The Radeon RX 6950 XT has a slightly 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 6950 XT also has a slightly 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 6950 XT at 335 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 4090 Laptop is faster than the Radeon RX 6950 XT.
