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 Nvidia GeForce GTX 770 Palit JetStream 4GB Edition.

The GTX 780 Ti has a 26 MHz higher core clock speed and 112 more Texture Mapping Units than the GTX 770. This results in the GTX 780 Ti providing 123.4 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 26 MHz higher core clock speed and 16 more Render Output Units than the GTX 770. This results in the GTX 780 Ti providing 18 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 GTX 780 Ti was released less than a year after the GTX 770, 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 GTX 770 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, the overall memory performance is about the same.

The GTX 780 Ti has 111.7 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the GTX 780 Ti is massively better than the GTX 770.

The GeForce GTX 770 Palit JetStream 4GB Edition has 1536 Shader Processing Units and the GeForce GTX 780 Ti EVGA Classified Kingpin Edition has 2880. However, the actual shader performance of the GTX 770 is 1667 and the actual shader performance of the GTX 780 Ti is 3275. The GTX 780 Ti having 1608 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 GTX 770.

The GeForce GTX 770 Palit JetStream 4GB Edition requires 230 Watts to run and the GeForce GTX 780 Ti EVGA Classified Kingpin Edition requires 250 Watts. We would recommend a PSU with at least 550 Watts for the GTX 770 and a PSU with at least 600 Watts for the GTX 780 Ti. The GTX 780 Ti requires 20 Watts more than the GTX 770 to run. The difference is not significant enough for the GTX 780 Ti to have a noticeably larger impact on your yearly electricity bills than the GTX 770.
