GeForce GTX 1080 vs GeForce GTX 660 Ti specs and performance

In our benchmarks, the GeForce GTX 1080 beats the GeForce GTX 660 Ti in gaming performance.

The GeForce GTX 1080 has a significantly 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. In addition, the GeForce GTX 1080 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 GTX 1080 has significantly more memory with 8 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 Ti has a slightly lower TDP at 150 W when compared to the GeForce GTX 1080 at 180 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 1080 is faster than the GeForce GTX 660 Ti.
