In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 Ti EVGA Classified Kingpin Edition are significantly better than the AMD Radeon R9 380X HIS IceQ X² Turbo 4GB Edition.

The GTX 780 Ti has a 52 MHz higher core clock speed and 112 more Texture Mapping Units than the R9 380X. This results in the GTX 780 Ti providing 126.7 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 780 Ti has a 52 MHz higher core clock speed and 16 more Render Output Units than the R9 380X. This results in the GTX 780 Ti providing 18.9 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 R9 380X was released over a year more recently than the GTX 780 Ti, and so the R9 380X 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 R9 380X has 1024 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 153.6 GB/sec greater memory bandwidth than the R9 380X, which means that the memory performance of the GTX 780 Ti is massively better than the R9 380X.

The Radeon R9 380X HIS IceQ X² Turbo 4GB Edition has 2048 Shader Processing Units and the GeForce GTX 780 Ti EVGA Classified Kingpin Edition has 2880. However, the actual shader performance of the R9 380X is 1776 and the actual shader performance of the GTX 780 Ti is 3275. The GTX 780 Ti having 1499 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 R9 380X.

The Radeon R9 380X HIS IceQ X² Turbo 4GB Edition requires 190 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 R9 380X and a PSU with at least 600 Watts for the GTX 780 Ti. The GTX 780 Ti requires 60 Watts more than the R9 380X 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 R9 380X.
