GeForce RTX 3060 Laptop vs GeForce GTX 660 benchmarks

According to the hardwareDB Benchmark, the GeForce RTX 3060 Laptop GPU is faster than the GeForce GTX 660 in gaming.

The GeForce GTX 660 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. Despite this, the GeForce RTX 3060 Laptop 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 GeForce RTX 3060 Laptop has significantly more memory with 5.97 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, the GeForce RTX 3060 Laptop has a significantly lower TDP at 80 W when compared to the GeForce GTX 660 at 140 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 3060 Laptop is better than the GeForce GTX 660.
