GeForce GTX 1080 vs GeForce GTX 660 benchmarks

For gaming, the GeForce GTX 1080 graphics card is better than the GeForce GTX 660 in our tests.

In our comparison, the GeForce GTX 1080 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 1080 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.

Next up, in terms of GPU memory, the GeForce GTX 1080 has significantly more memory with 8 GiB of memory compared to 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 660 has a slightly lower TDP at 140 W when compared to the GeForce GTX 1080 at 180 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 1080 over the GeForce GTX 660.
