GeForce GTX 950M vs GeForce GTX 680 benchmarks

In our benchmarks, the GeForce GTX 680 beats the GeForce GTX 950M in gaming performance.

In our comparison, the GeForce GTX 680 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. Despite this, the GeForce GTX 950M 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 680 at 195 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 680 over the GeForce GTX 950M.
