RTX A4000 Laptop vs GeForce RTX 4090 specs and performance

In our benchmarks, the GeForce RTX 4090 beats the RTX A4000 Laptop in gaming performance.

In our comparison, the GeForce RTX 4090 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 4090 also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the RTX A4000 Laptop has a significantly lower TDP at 140 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 terms of raw gaming performance in our GPU benchmark, the GeForce RTX 4090 is better than the RTX A4000 Laptop.
