In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are significantly better than the Nvidia GeForce GTX 680 SLI.

The GTX 980 has a 120 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 680. This results in the GTX 980 providing 30.8 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 980 has a 120 MHz higher core clock speed and 64 more Render Output Units than the GTX 680. This results in the GTX 980 providing 79.7 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 over a year more recently than the GTX 680, and so the GTX 980 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 680.

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 4096 MB more video memory than the GTX 680, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 980 also has superior memory performance overall.

The GTX 980 has 64.3 GB/sec greater memory bandwidth than the GTX 680, which means that the memory performance of the GTX 980 is much better than the GTX 680.

The GeForce GTX 980 4GB SLI has 4096 Shader Processing Units and the GeForce GTX 680 SLI has 3072. However, the actual shader performance of the GTX 980 is 6724 and the actual shader performance of the GTX 680 is 3250. The GTX 980 having 3474 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 680.

The GeForce GTX 980 4GB SLI requires 350 Watts to run and the GeForce GTX 680 SLI requires 390 Watts. We would recommend a PSU with at least 750 Watts for the GTX 980. The GTX 680 requires 40 Watts more than the GTX 980 to run. The difference is significant enough that the GTX 680 may have a slight 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.

Architecture
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.

GPU
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.

Performance
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 680 SLI is a solution of two GeForce GTX 680 put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 680 to know more about its chip.
As usual, 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 around 60% better than a single GeForce GTX 680 performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 680. Expect this combination to draw up to 390 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
