In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1050 Ti 4GB are noticeably better than the Nvidia GeForce GTX 950 LP MSI OC v3 2GB Edition.

The GTX 1050 Ti has a 214 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 950. This results in the GTX 1050 Ti providing 10.3 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 1050 Ti has a 214 MHz higher core clock speed than the GTX 950 and the same number of Render Output Units. This results in the GTX 1050 Ti providing 6.9 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 1050 Ti 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.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 1050 Ti has 2048 MB more video memory than the GTX 950, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 1050 Ti also has superior memory performance overall.

The GTX 1050 Ti has 6.3 GB/sec greater memory bandwidth than the GTX 950, which means that the memory performance of the GTX 1050 Ti is marginally better than the GTX 950.

Both the GeForce GTX 1050 Ti 4GB and the GeForce GTX 950 LP MSI OC v3 2GB Edition have 768 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GTX 1050 Ti is 1443 and by the GTX 950 is 1299. Knowing that the shader performance of the GTX 1050 Ti is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GTX 1050 Ti transistor size technology is 12 nm (nanometers) smaller than the GTX 950. This means that the GTX 1050 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GTX 950.

The GeForce GTX 1050 Ti 4GB requires 75 Watts to run and the GeForce GTX 950 LP MSI OC v3 2GB Edition requires 75 Watts. We would recommend a PSU with at least 300 Watts for the GTX 1050 Ti and a PSU with at least 350 Watts for the GTX 950. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
