GeForce GTX 965M vs GeForce GTX 870M specs and performance

According to the hardwareDB Benchmark, the GeForce GTX 965M GPU is faster than the GeForce GTX 870M in gaming.

In our comparison, the GeForce GTX 965M 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 965M also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the GeForce GTX 965M has a significantly lower TDP at 60 W when compared to the GeForce GTX 870M at 100 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 conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 965M over the GeForce GTX 870M.
