GeForce GTX 660M vs GeForce GTX 750 Ti specs and performance

In our benchmarks, the GeForce GTX 750 Ti beats the GeForce GTX 660M in gaming performance.

The GeForce GTX 750 Ti 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 750 Ti also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the GeForce GTX 750 Ti has significantly more memory with 4 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 660M has a slightly lower TDP at 50 W when compared to the GeForce GTX 750 Ti at 60 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 750 Ti is better than the GeForce GTX 660M.
