In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 490X 8GB are massively better than the Nvidia GeForce GTX 950 Asus OC 2GB Edition.

The GTX 950 has a 102 MHz higher core clock speed than the RX 490X, but the RX 490X has 336 more Texture Mapping Units than the GTX 950. As a result, the RX 490X exhibits a 331.1 GTexel/s better Texture Fill Rate than the GTX 950. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 950 has a 102 MHz higher core clock speed than the RX 490X, but the RX 490X has 96 more Render Output Units than the GTX 950. As a result, the RX 490X exhibits a 92.7 GPixel/s better Pixel Fill Rate than the GTX 950. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 490X 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 490X has 6144 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 490X, which means that the memory performance of the GTX 950 is massively better than the RX 490X.

The GeForce GTX 950 Asus OC 2GB Edition has 768 Shader Processing Units and the Radeon RX 490X 8GB has 6144. However, the actual shader performance of the GTX 950 is 1326. The RX 490X having 4818 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 490X delivers a massively smoother and more efficient experience when processing graphical data than the GTX 950.

The RX 490X transistor size technology is 14 nm (nanometers) smaller than the GTX 950. This means that the RX 490X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 950.

The GeForce GTX 950 Asus OC 2GB Edition requires 75 Watts to run and the Radeon RX 490X 8GB requires 250 Watts. We would recommend a PSU with at least 350 Watts for the GTX 950 and a PSU with at least 600 Watts for the RX 490X. The RX 490X requires 175 Watts more than the GTX 950 to run. The difference is significant enough that the RX 490X may have an adverse affect on your yearly electricity bills in comparison to the GTX 950.
