In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1070 Zotac AMP! are significantly better than the AMD Radeon RX 570 4GB.

The GTX 1070 has a 439 MHz higher core clock speed but 8 fewer Texture Mapping Units than the RX 570. The lower TMU count doesn't matter, though, as altogether the GTX 1070 manages to provide 43.3 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 1070 has a 439 MHz higher core clock speed and 32 more Render Output Units than the RX 570. This results in the GTX 1070 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 570 was released less than a year after the GTX 1070, 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 1070 has 4096 MB more video memory than the RX 570, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 1070 also has superior memory performance overall.

The GTX 1070 has 32.3 GB/sec greater memory bandwidth than the RX 570, which means that the memory performance of the GTX 1070 is noticeably better than the RX 570.

The Radeon RX 570 4GB has 2048 Shader Processing Units and the GeForce GTX 1070 Zotac AMP! has 1920. However, the actual shader performance of the RX 570 is 2548 and the actual shader performance of the GTX 1070 is 4658. The GTX 1070 having 2110 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 1070 delivers a massively smoother and more efficient experience when processing graphical data than the RX 570.

The RX 570 transistor size technology is 2 nm (nanometers) smaller than the GTX 1070. This means that the RX 570 is expected to run very slightly cooler and achieve higher clock frequencies than the GTX 1070.

The Radeon RX 570 4GB requires 120 Watts to run and the GeForce GTX 1070 Zotac AMP! requires 220 Watts. We would recommend a PSU with at least 450 Watts for the RX 570 and a PSU with at least 500 Watts for the GTX 1070. The GTX 1070 requires 100 Watts more than the RX 570 to run. The difference is significant enough that the GTX 1070 may have an adverse affect on your yearly electricity bills in comparison to the RX 570.
