GeForce GTX 1070 vs GeForce GTX 660 comparison

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

Our database shows that the GeForce GTX 1070 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 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 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 has a slightly lower TDP at 140 W when compared to the GeForce GTX 1070 at 150 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 is faster than the GeForce GTX 660.
