RTX A4000 vs GeForce RTX 4090 Laptop specs and performance

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

Our database shows that the GeForce RTX 4090 Laptop 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 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 4090 Laptop has a slightly lower TDP at 120 W when compared to the RTX A4000 at 140 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 4090 Laptop is faster than the RTX A4000.
