GeForce GTX 660M vs GeForce GTX 750 comparison

According to the hardwareDB Benchmark, the GeForce GTX 750 GPU is faster than the GeForce GTX 660M in gaming.

Our database shows that the GeForce GTX 750 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 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, they both have the same amount of memory at 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 660M has a slightly lower TDP at 50 W when compared to the GeForce GTX 750 at 55 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 750 over the GeForce GTX 660M.
