In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480X 4GB are massively better than the Nvidia GeForce GTX 950 LP MSI OC v3 2GB Edition.

The RX 480X has a 74 MHz higher core clock speed and 208 more Texture Mapping Units than the GTX 950. This results in the RX 480X providing 242.8 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 RX 480X has a 74 MHz higher core clock speed and 96 more Render Output Units than the GTX 950. This results in the RX 480X providing 112.8 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 RX 480X 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 RX 480X has 2048 MB more video memory than the GTX 950, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 950 has superior memory performance.

The GTX 950 has 105.8 GB/sec greater memory bandwidth than the RX 480X, which means that the memory performance of the GTX 950 is massively better than the RX 480X.

The GeForce GTX 950 LP MSI OC v3 2GB Edition has 768 Shader Processing Units and the Radeon RX 480X 4GB has 4096. However, the actual shader performance of the GTX 950 is 1299 and the actual shader performance of the RX 480X is 5325. The RX 480X having 4026 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 480X delivers a massively smoother and more efficient experience when processing graphical data than the GTX 950.

The RX 480X transistor size technology is 14 nm (nanometers) smaller than the GTX 950. This means that the RX 480X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 950.

The GeForce GTX 950 LP MSI OC v3 2GB Edition requires 75 Watts to run and the Radeon RX 480X 4GB requires 175 Watts. We would recommend a PSU with at least 350 Watts for the GTX 950 and a PSU with at least 500 Watts for the RX 480X. The RX 480X requires 100 Watts more than the GTX 950 to run. The difference is significant enough that the RX 480X may have an adverse affect on your yearly electricity bills in comparison to the GTX 950.
