RTX A4000 Laptop vs GeForce RTX 4090 Laptop specs and performance

For gaming, the GeForce RTX 4090 Laptop graphics card is better than the RTX A4000 Laptop in our tests.

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: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the GeForce RTX 4090 Laptop has a slightly lower TDP at 120 W when compared to the RTX A4000 Laptop at 140 W. TDP (Thermal Design Power) measures total heat output from the chip.

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