GeForce GTX 660 vs RTX A4000 specs and performance

According to the hardwareDB Benchmark, the RTX A4000 GPU is faster than the GeForce GTX 660 in gaming.

In our comparison, the GeForce GTX 660 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. Despite this, the RTX A4000 has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the RTX A4000 has significantly more memory with 16 GiB of memory compared to 3 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, both the GeForce GTX 660 and the RTX A4000 have an identical TDP. 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 RTX A4000 is better than the GeForce GTX 660.
