Radeon RX 6900 XT vs GeForce RTX 4070 Laptop comparison

For gaming, the Radeon RX 6900 XT graphics card is better than the GeForce RTX 4070 Laptop in our tests.

In our comparison, the Radeon RX 6900 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 6900 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 4070 Laptop has a significantly lower TDP at 115 W when compared to the Radeon RX 6900 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 Radeon RX 6900 XT is better than the GeForce RTX 4070 Laptop.
