GeForce RTX 4090 vs Radeon RX 7900 XT specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 4090 GPU is faster than the Radeon RX 7900 XT in gaming.

In our comparison, 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. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

As stated by the manufacturer, the GeForce RTX 4090 has slightly more memory with 24 GiB of memory compared to 20 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 7900 XT has a much lower TDP at 315 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 7900 XT.
