In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1080 are significantly better than the AMD Radeon RX 570X 4GB.

The GeForce GTX 1080 has a 439 MHz higher core clock speed and 32 more Texture Mapping Units than the RX 570X. This results in the GeForce GTX 1080 providing 107.6 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 GeForce GTX 1080 has a 439 MHz higher core clock speed and 32 more Render Output Units than the RX 570X. This results in the GeForce GTX 1080 providing 65.4 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 570X was released less than a year after the GeForce GTX 1080, 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 GeForce GTX 1080 has 4096 MB more video memory than the RX 570X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 1080 also has superior memory performance overall.

The GeForce GTX 1080 has 96.3 GB/sec greater memory bandwidth than the RX 570X, which means that the memory performance of the GeForce GTX 1080 is massively better than the RX 570X.

The Radeon RX 570X 4GB has 2048 Shader Processing Units and the GeForce GTX 1080 has 2560. However, the actual shader performance of the RX 570X is 2548 and the actual shader performance of the GeForce GTX 1080 is 5989. The GeForce GTX 1080 having 3441 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 1080 delivers a massively smoother and more efficient experience when processing graphical data than the RX 570X.

The RX 570X transistor size technology is 2 nm (nanometers) smaller than the GeForce GTX 1080. This means that the RX 570X is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GTX 1080.

The Radeon RX 570X 4GB requires 120 Watts to run and the GeForce GTX 1080 requires 180 Watts. We would recommend a PSU with at least 450 Watts for the RX 570X and a PSU with at least 500 Watts for the GeForce GTX 1080. The GeForce GTX 1080 requires 60 Watts more than the RX 570X to run. The difference is significant enough that the GeForce GTX 1080 may have an adverse affect on your yearly electricity bills in comparison to the RX 570X.
