In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce RTX 2080 Ti SLI are massively better than the Nvidia GeForce GTX 1060 Gigabyte Windforce 2X OC 3GB.

The GTX 1060 has a 206 MHz higher core clock speed than the RTX 2080 Ti, but the RTX 2080 Ti has 200 more Texture Mapping Units than the GTX 1060. As a result, the RTX 2080 Ti exhibits a 255.2 GTexel/s better Texture Fill Rate than the GTX 1060. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 1060 has a 206 MHz higher core clock speed than the RTX 2080 Ti, but the RTX 2080 Ti has 40 more Render Output Units than the GTX 1060. As a result, the RTX 2080 Ti exhibits a 44.1 GPixel/s better Pixel Fill Rate than the GTX 1060. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RTX 2080 Ti was released over a year more recently than the GTX 1060, and so the RTX 2080 Ti is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 1060.

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 RTX 2080 Ti has 8192 MB more video memory than the GTX 1060, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RTX 2080 Ti also has superior memory performance overall.

The RTX 2080 Ti has 423.8 GB/sec greater memory bandwidth than the GTX 1060, which means that the memory performance of the RTX 2080 Ti is massively better than the GTX 1060.

The GeForce RTX 2080 Ti SLI has 4352 Shader Processing Units and the GeForce GTX 1060 Gigabyte Windforce 2X OC 3GB has 1152. However, the actual shader performance of the RTX 2080 Ti is 7116 and the actual shader performance of the GTX 1060 is 2040. The RTX 2080 Ti having 5076 better shader performance and an altogether better performance when taking into account other relevant data means that the RTX 2080 Ti delivers a massively smoother and more efficient experience when processing graphical data than the GTX 1060.

The RTX 2080 Ti transistor size technology is 4 nm (nanometers) smaller than the GTX 1060. This means that the RTX 2080 Ti is expected to run very slightly cooler and achieve higher clock frequencies than the GTX 1060.

The GeForce RTX 2080 Ti SLI requires 260 Watts to run and the GeForce GTX 1060 Gigabyte Windforce 2X OC 3GB requires 120 Watts. We would recommend a PSU with at least 650 Watts for the RTX 2080 Ti and a PSU with at least 400 Watts for the GTX 1060. The RTX 2080 Ti requires 140 Watts more than the GTX 1060 to run. The difference is significant enough that the RTX 2080 Ti may have an adverse affect on your yearly electricity bills in comparison to the GTX 1060.
