NVIDIA GeForce RTX 4090 vs NVIDIA GeForce RTX 5080

GeForce RTX 4090 vs GeForce RTX 5080 specs and performance

For gaming, the GeForce RTX 4090 graphics card is better than the GeForce RTX 5080 in our tests.

Our database shows that the GeForce RTX 5080 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 5080 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the GeForce RTX 4090 has significantly more memory with 24 GiB of memory compared to 16 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the GeForce RTX 5080 has a slightly lower TDP at 360 W when compared to the GeForce RTX 4090 at 450 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 4090 over the GeForce RTX 5080.
