GeForce GTX 660 vs GeForce GTX 860M benchmarks

In our benchmarks, the GeForce GTX 660 beats the GeForce GTX 860M in gaming performance.

The GeForce GTX 860M has a slightly 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 860M also has a slightly 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.

In addition, the GeForce GTX 860M has a significantly lower TDP at 75 W when compared to the GeForce GTX 660 at 140 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 660 is faster than the GeForce GTX 860M.
