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 570 GS-GLH Edition.

The RTX 2080 Ti has a 550 MHz higher core clock speed and 212 more Texture Mapping Units than the GTX 570. This results in the RTX 2080 Ti providing 319.2 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 RTX 2080 Ti has a 550 MHz higher core clock speed and 48 more Render Output Units than the GTX 570. This results in the RTX 2080 Ti providing 86.8 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 RTX 2080 Ti was released over three years more recently than the GTX 570, and so the RTX 2080 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 570 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 RTX 2080 Ti has 9984 MB more video memory than the GTX 570, 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 456 GB/sec greater memory bandwidth than the GTX 570, which means that the memory performance of the RTX 2080 Ti is massively better than the GTX 570.

The GeForce RTX 2080 Ti SLI has 4352 Shader Processing Units and the GeForce GTX 570 GS-GLH Edition has 480. However, the actual shader performance of the RTX 2080 Ti is 7116 and the actual shader performance of the GTX 570 is 768. The RTX 2080 Ti having 6348 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 570.

The RTX 2080 Ti transistor size technology is 28 nm (nanometers) smaller than the GTX 570. This means that the RTX 2080 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GTX 570.

The GeForce RTX 2080 Ti SLI requires 260 Watts to run and the GeForce GTX 570 GS-GLH Edition requires 219 Watts. We would recommend a PSU with at least 650 Watts for the RTX 2080 Ti and a PSU with at least 550 Watts for the GTX 570. The RTX 2080 Ti requires 41 Watts more than the GTX 570 to run. The difference is significant enough that the RTX 2080 Ti may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 570.
