In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 950 LP MSI OC v3 2GB Edition are significantly better than the Nvidia GeForce GT 940 2GB.

The GT 940 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The GT 940 was released less than a year after the GTX 950, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTX 950 LP MSI OC v3 2GB Edition and the GeForce GT 940 2GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 950 has 25.8 GB/sec greater memory bandwidth than the GT 940, which means that the memory performance of the GTX 950 is slightly better than the GT 940.

The GeForce GTX 950 LP MSI OC v3 2GB Edition has 768 Shader Processing Units and the GeForce GT 940 2GB has 512. However, the actual shader performance of the GTX 950 is 1299 and the actual shader performance of the GT 940 is 0. The GTX 950 having 1299 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 950 delivers a massively smoother and more efficient experience when processing graphical data than the GT 940.

The GeForce GTX 950 LP MSI OC v3 2GB Edition requires 75 Watts to run and the GeForce GT 940 2GB requires 60 Watts. We would recommend a PSU with at least 350 Watts for the GTX 950 and a PSU with at least 300 Watts for the GT 940. The GTX 950 requires 15 Watts more than the GT 940 to run. The difference is not significant enough for the GTX 950 to have a noticeably larger impact on your yearly electricity bills than the GT 940.
