UHD 770 vs GeForce GTX 660M specs and performance

In our benchmarks, the UHD 770 beats the GeForce GTX 660M in gaming performance.

In our comparison, the GeForce GTX 660M has a significantly 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. Despite this, the UHD 770 has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the UHD 770 has a significantly lower TDP at 15 W when compared to the GeForce GTX 660M at 50 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the UHD 770 is better than the GeForce GTX 660M.
