In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480X 4GB are noticeably better than the AMD Radeon RX 570 Asus ROG Strix Gaming OC 4GB.

The RX 570 has a 18 MHz higher core clock speed than the RX 480X, but the RX 480X has 128 more Texture Mapping Units than the RX 570. As a result, the RX 480X exhibits a 144.9 GTexel/s better Texture Fill Rate than the RX 570. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 570 has a 18 MHz higher core clock speed than the RX 480X, but the RX 480X has 96 more Render Output Units than the RX 570. As a result, the RX 480X exhibits a 109.8 GPixel/s better Pixel Fill Rate than the RX 570. 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 RX 480X, 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 Radeon RX 570 Asus ROG Strix Gaming OC 4GB and the Radeon RX 480X 4GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The RX 570 has 224 GB/sec greater memory bandwidth than the RX 480X, which means that the memory performance of the RX 570 is massively better than the RX 480X.

The Radeon RX 570 Asus ROG Strix Gaming OC 4GB has 2048 Shader Processing Units and the Radeon RX 480X 4GB has 4096. However, the actual shader performance of the RX 570 is 2683 and the actual shader performance of the RX 480X is 5325. The RX 480X having 2642 better shader performance is not particularly notable, as altogether the RX 570 performs better when taking into account other relevant data.

The Radeon RX 570 Asus ROG Strix Gaming OC 4GB requires 120 Watts to run and the Radeon RX 480X 4GB requires 175 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 RX 480X. The RX 480X requires 55 Watts more than the RX 570 to run. The difference is significant enough that the RX 480X may have an adverse affect on your yearly electricity bills in comparison to the RX 570.
