GeForce GTX 950M vs GeForce GTX 660 benchmarks

According to the hardwareDB Benchmark, the GeForce GTX 660 GPU is faster than the GeForce GTX 950M in gaming.

The GeForce GTX 950M has a slightly 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 950M 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 950M has a significantly lower TDP at 75 W when compared to the GeForce GTX 660 at 140 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 660 over the GeForce GTX 950M.
