RTX A4000 Laptop vs GeForce RTX 4080 specs and performance

For gaming, the GeForce RTX 4080 graphics card is better than the RTX A4000 Laptop in our tests.

Our database shows that the GeForce RTX 4080 has a significantly 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 4080 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 RTX A4000 Laptop has a significantly lower TDP at 140 W when compared to the GeForce RTX 4080 at 420 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 4080 is better than the RTX A4000 Laptop.
