GeForce RTX 4090 Laptop vs GeForce RTX 4080 Laptop benchmarks

In our benchmarks, the GeForce RTX 4090 Laptop beats the GeForce RTX 4080 Laptop in gaming performance.

The GeForce RTX 4090 Laptop 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 Laptop 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.

In addition, the GeForce RTX 4080 Laptop has a slightly lower TDP at 110 W when compared to the GeForce RTX 4090 Laptop at 120 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 4090 Laptop is better than the GeForce RTX 4080 Laptop.
