In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 590 ASRock Phantom Gaming X OC 8GB are very slightly better than the Nvidia GeForce GTX 780 Ti EVGA Classified Kingpin Edition.

The RX 590 has a 397 MHz higher core clock speed than the GTX 780 Ti, but the GTX 780 Ti has 96 more Texture Mapping Units than the RX 590. As a result, the GTX 780 Ti exhibits a 45.8 GTexel/s better Texture Fill Rate than the RX 590. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 590 has a 397 MHz higher core clock speed than the GTX 780 Ti, but the GTX 780 Ti has 16 more Render Output Units than the RX 590. As a result, the GTX 780 Ti exhibits a 4.5 GPixel/s better Pixel Fill Rate than the RX 590. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 590 was released over three years more recently than the GTX 780 Ti, and so the RX 590 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 RX 590 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, the overall memory performance is about the same.

The GTX 780 Ti has 79 GB/sec greater memory bandwidth than the RX 590, which means that the memory performance of the GTX 780 Ti is much better than the RX 590.

The Radeon RX 590 ASRock Phantom Gaming X OC 8GB has 2304 Shader Processing Units and the GeForce GTX 780 Ti EVGA Classified Kingpin Edition has 2880. However, the actual shader performance of the RX 590 is 3666 and the actual shader performance of the GTX 780 Ti is 3275. The RX 590 having 391 better shader performance is not particularly notable, as altogether the GTX 780 Ti performs better when taking into account other relevant data.

The RX 590 transistor size technology is 16 nm (nanometers) smaller than the GTX 780 Ti. This means that the RX 590 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 780 Ti.

The Radeon RX 590 ASRock Phantom Gaming X OC 8GB requires 175 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 590 and a PSU with at least 600 Watts for the GTX 780 Ti. The GTX 780 Ti requires 75 Watts more than the RX 590 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 590.
