In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are very slightly better than the Nvidia GeForce GTX 780 Ti SLI.

The GTX 980 has a 251 MHz higher core clock speed than the GTX 780 Ti, but the GTX 780 Ti has 224 more Texture Mapping Units than the GTX 980. As a result, the GTX 780 Ti exhibits a 131.7 GTexel/s better Texture Fill Rate than the GTX 980. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 980 has a 251 MHz higher core clock speed and 32 more Render Output Units than the GTX 780 Ti. This results in the GTX 980 providing 60.1 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 GTX 980 was released less than a year after the GTX 780 Ti, 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 980 has 2048 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 223.2 GB/sec greater memory bandwidth than the GTX 980, which means that the memory performance of the GTX 780 Ti is massively better than the GTX 980.

The GeForce GTX 980 4GB SLI has 4096 Shader Processing Units and the GeForce GTX 780 Ti SLI has 5760. However, the actual shader performance of the GTX 980 is 6724 and the actual shader performance of the GTX 780 Ti is 5345. The GTX 980 having 1379 better shader performance is not particularly notable, as altogether the GTX 780 Ti performs better when taking into account other relevant data.

The GeForce GTX 980 4GB SLI requires 350 Watts to run and the GeForce GTX 780 Ti SLI requires 500 Watts. We would recommend a PSU with at least 750 Watts for the GTX 980 and a PSU with at least 750 Watts for the GTX 780 Ti. The GTX 780 Ti requires 150 Watts more than the GTX 980 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 GTX 980.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 980 4GB SLI is a solution of two GeForce GTX 980 4GB put together using NVIDIA's SLI technology.

The Second variant of the Maxwell Architecture, despite being also manufactured with a 28nm technology, has an extremely large L2 Cache and features a Third Generation Delta Color Compression which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

It consists of 2 GPUs codenamed GM204-400-A1 which, together, offer 4096 Shader Processing Units, 256 TMUs and 128 ROPs, on a 512-bit memory interface of fast GDDR5. The central unit runs at 1126MHz and goes up to 1216MHz, in Turbo Mode, while the memory clock operates at 1753MHz.

Power Consumption
Power Consumption lies between 300W and 400W.

Gaming benchmarks prove that at 4K (3840x2160) GeForce GTX 980 4GB SLI is over 7% faster than AMD's Radeon R9 295X2.

System Suggestions
We recommend a very strong processor (Intel Core i7 Six Core/AMD FX Eight Core) and 16GB of RAM for a system with GeForce GTX 980 4GB SLI.
GeForce GTX 780 Ti SLI is a solution of two GeForce GTX 780 Ti put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 780 Ti to know more about its chip.
SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to 62% better than a single GeForce GTX 780 Ti performing by itself it might be worse (depending on whether or not the 3D game supports SLI or in the graphics driver) than a single GeForce GTX 780 Ti. Expect this combination to draw up to 500 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
