GeForce GTX 660M vs GeForce GTX 860M benchmarks

For gaming, the GeForce GTX 860M graphics card is better than the GeForce GTX 660M in our tests.

Our database shows that 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 maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the GeForce GTX 660M has a significantly lower TDP at 50 W when compared to the GeForce GTX 860M at 75 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 860M over the GeForce GTX 660M.
