In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX Vega 56 8GB are massively better than the Nvidia GeForce GTX 1050 Ti 4GB.

The RX Vega has a 210 MHz higher core clock speed and 176 more Texture Mapping Units than the GTX 1050 Ti. This results in the RX Vega providing 274.1 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 RX Vega has a 210 MHz higher core clock speed and 24 more Render Output Units than the GTX 1050 Ti. This results in the RX Vega providing 42.7 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 Vega was released less than a year after the GTX 1050 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 RX Vega has 4096 MB more video memory than the GTX 1050 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RX Vega also has superior memory performance overall.

The RX Vega has 143.9 GB/sec greater memory bandwidth than the GTX 1050 Ti, which means that the memory performance of the RX Vega is massively better than the GTX 1050 Ti.

The Radeon RX Vega 56 8GB has 3584 Shader Processing Units and the GeForce GTX 1050 Ti 4GB has 768. However, the actual shader performance of the RX Vega is 3494 and the actual shader performance of the GTX 1050 Ti is 1443. The RX Vega having 2051 better shader performance and an altogether better performance when taking into account other relevant data means that the RX Vega delivers a massively smoother and more efficient experience when processing graphical data than the GTX 1050 Ti.

The RX Vega transistor size technology is 2 nm (nanometers) smaller than the GTX 1050 Ti. This means that the RX Vega is expected to run very slightly cooler and achieve higher clock frequencies than the GTX 1050 Ti.

The Radeon RX Vega 56 8GB requires 300 Watts to run and the GeForce GTX 1050 Ti 4GB requires 75 Watts. We would recommend a PSU with at least 600 Watts for the RX Vega and a PSU with at least 300 Watts for the GTX 1050 Ti. The RX Vega requires 225 Watts more than the GTX 1050 Ti to run. The difference is significant enough that the RX Vega may have an adverse affect on your yearly electricity bills in comparison to the GTX 1050 Ti.
