GeForce GTX 1080 Ti vs GeForce GTX 660 specs and performance

According to the hardwareDB Benchmark, the GeForce GTX 1080 Ti GPU is faster than the GeForce GTX 660 in gaming.

Our database shows that the GeForce GTX 1080 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 GTX 1080 Ti also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the GeForce GTX 1080 Ti has significantly more memory with 11 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 GTX 1080 Ti at 250 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 1080 Ti over the GeForce GTX 660.
