GeForce GTX 1070 Ti vs GeForce GTX 660 Ti comparison

In our benchmarks, the GeForce GTX 1070 Ti beats the GeForce GTX 660 Ti in gaming performance.

Our database shows that the GeForce GTX 1070 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 1070 Ti also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Furthermore, the spec sheet for both these GPUs show that the GeForce GTX 1070 Ti has significantly more memory with 8 GiB of memory compared to 3 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the GeForce GTX 660 Ti has a slightly lower TDP at 150 W when compared to the GeForce GTX 1070 Ti 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 1070 Ti is faster than the GeForce GTX 660 Ti.
