GeForce GTX 660 vs GeForce RTX 3090 Ti specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 3090 Ti GPU is faster than the GeForce GTX 660 in gaming.

Our database shows that the GeForce RTX 3090 Ti 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 3090 Ti also 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.

Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 3090 Ti has significantly more memory with 24 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 GTX 660 has a significantly lower TDP at 140 W when compared to the GeForce RTX 3090 Ti at 450 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 3090 Ti is better than the GeForce GTX 660.
