RTX A4000 vs GeForce RTX 4090 benchmarks

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

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

Next up, in terms of GPU memory, the GeForce RTX 4090 has significantly more memory with 24 GiB of memory compared to 16 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the RTX A4000 has a significantly lower TDP at 140 W when compared to the GeForce RTX 4090 at 450 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 4090 is better than the RTX A4000.
