In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480X 8GB are very slightly better than the Nvidia GeForce GTX 780 Ti EVGA Classified Kingpin Edition.

The RX 480X has a 178 MHz higher core clock speed than the GTX 780 Ti, but the GTX 780 Ti has 112 more Texture Mapping Units than the RX 480X. As a result, the GTX 780 Ti exhibits a 97.3 GTexel/s better Texture Fill Rate than the RX 480X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 480X has a 178 MHz higher core clock speed and 16 more Render Output Units than the GTX 780 Ti. This results in the RX 480X providing 28.5 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 480X was released over a year more recently than the GTX 780 Ti, and so the RX 480X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 780 Ti.

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 480X has 5120 MB more video memory than the GTX 780 Ti, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 780 Ti has superior memory performance.

The GTX 780 Ti has 336 GB/sec greater memory bandwidth than the RX 480X, which means that the memory performance of the GTX 780 Ti is massively better than the RX 480X.

The Radeon RX 480X 8GB has 2048 Shader Processing Units and the GeForce GTX 780 Ti EVGA Classified Kingpin Edition has 2880. However, the actual shader performance of the RX 480X is 2560 and the actual shader performance of the GTX 780 Ti is 3275. The GTX 780 Ti having 715 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 780 Ti delivers a massively smoother and more efficient experience when processing graphical data than the RX 480X.

The RX 480X transistor size technology is 14 nm (nanometers) smaller than the GTX 780 Ti. This means that the RX 480X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 780 Ti.

The Radeon RX 480X 8GB requires 150 Watts to run and the GeForce GTX 780 Ti EVGA Classified Kingpin Edition requires 250 Watts. We would recommend a PSU with at least 500 Watts for the RX 480X and a PSU with at least 600 Watts for the GTX 780 Ti. The GTX 780 Ti requires 100 Watts more than the RX 480X to run. The difference is significant enough that the GTX 780 Ti may have an adverse affect on your yearly electricity bills in comparison to the RX 480X.
