Radeon RX 6950 XT vs GeForce RTX 4090 benchmarks

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

The GeForce RTX 4090 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 GeForce RTX 4090 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the GeForce RTX 4090 has significantly more memory with 24 GiB of memory compared to 16 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6950 XT has a slightly lower TDP at 335 W when compared to the GeForce RTX 4090 at 450 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 4090 is better than the Radeon RX 6950 XT.
