In terms of overall gaming performance, the graphical capabilities of the AMD Radeon Pro Duo 32GB are significantly better than the Nvidia GeForce GTX 780 Ti EVGA Classified Kingpin Edition.

The Pro Duo has a 171 MHz higher core clock speed than the GTX 780 Ti, but the GTX 780 Ti has 96 more Texture Mapping Units than the Pro Duo. As a result, the GTX 780 Ti exhibits a 78.3 GTexel/s better Texture Fill Rate than the Pro Duo. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Pro Duo has a 171 MHz higher core clock speed and 16 more Render Output Units than the GTX 780 Ti. This results in the Pro Duo providing 28.1 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 Pro Duo was released over three years more recently than the GTX 780 Ti, and so the Pro Duo is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 780 Ti 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 Pro Duo has 28928 MB more video memory than the GTX 780 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Pro Duo also has superior memory performance overall.

The Pro Duo has 176 GB/sec greater memory bandwidth than the GTX 780 Ti, which means that the memory performance of the Pro Duo is massively better than the GTX 780 Ti.

The Radeon Pro Duo 32GB has 4608 Shader Processing Units and the GeForce GTX 780 Ti EVGA Classified Kingpin Edition has 2880. However, the actual shader performance of the Pro Duo is 5728 and the actual shader performance of the GTX 780 Ti is 3275. The Pro Duo having 2453 better shader performance and an altogether better performance when taking into account other relevant data means that the Pro Duo delivers a massively smoother and more efficient experience when processing graphical data than the GTX 780 Ti.

The Radeon Pro Duo 32GB requires 250 Watts to run and the GeForce GTX 780 Ti EVGA Classified Kingpin Edition requires 250 Watts. We would recommend a PSU with at least 600 Watts for the Pro Duo and a PSU with at least 600 Watts for the GTX 780 Ti. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
