In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1080 Ti Kuroutoshikou Founders Edition 11GB are massively better than the AMD Radeon RX 560 4GB.

The GTX 1080 Ti has a 305 MHz higher core clock speed and 160 more Texture Mapping Units than the RX 560. This results in the GTX 1080 Ti providing 256.3 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 1080 Ti has a 305 MHz higher core clock speed and 72 more Render Output Units than the RX 560. This results in the GTX 1080 Ti providing 111.4 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 560 was released less than a year after the GTX 1080 Ti, 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 1080 Ti has 7168 MB more video memory than the RX 560, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 1080 Ti also has superior memory performance overall.

The GTX 1080 Ti has 372.4 GB/sec greater memory bandwidth than the RX 560, which means that the memory performance of the GTX 1080 Ti is massively better than the RX 560.

The Radeon RX 560 4GB has 1024 Shader Processing Units and the GeForce GTX 1080 Ti Kuroutoshikou Founders Edition 11GB has 3584. However, the actual shader performance of the RX 560 is 1306 and the actual shader performance of the GTX 1080 Ti is 7654. The GTX 1080 Ti having 6348 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 1080 Ti delivers a massively smoother and more efficient experience when processing graphical data than the RX 560.

The RX 560 transistor size technology is 2 nm (nanometers) smaller than the GTX 1080 Ti. This means that the RX 560 is expected to run very slightly cooler and achieve higher clock frequencies than the GTX 1080 Ti.

The Radeon RX 560 4GB requires 80 Watts to run and the GeForce GTX 1080 Ti Kuroutoshikou Founders Edition 11GB requires 220 Watts. We would recommend a PSU with at least 450 Watts for the RX 560 and a PSU with at least 600 Watts for the GTX 1080 Ti. The GTX 1080 Ti requires 140 Watts more than the RX 560 to run. The difference is significant enough that the GTX 1080 Ti may have an adverse affect on your yearly electricity bills in comparison to the RX 560.
