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 780 Asus Strix OC 6GB Edition.

The GTX 980 has a 237 MHz higher core clock speed and 64 more Texture Mapping Units than the GTX 780. This results in the GTX 980 providing 117.6 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 237 MHz higher core clock speed and 80 more Render Output Units than the GTX 780. This results in the GTX 980 providing 101.4 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, 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, 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 160.4 GB/sec greater memory bandwidth than the GTX 780, which means that the memory performance of the GTX 980 is massively better than the GTX 780.

The GeForce GTX 780 Asus Strix OC 6GB Edition has 2304 Shader Processing Units and the GeForce GTX 980 4GB SLI has 4096. However, the actual shader performance of the GTX 780 is 2168 and the actual shader performance of the GTX 980 is 6724. The GTX 980 having 4556 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 780.

The GeForce GTX 780 Asus Strix OC 6GB Edition requires 250 Watts to run and the GeForce GTX 980 4GB SLI requires 350 Watts. We would recommend a PSU with at least 600 Watts for the GTX 780 and a PSU with at least 750 Watts for the GTX 980. The GTX 980 requires 100 Watts more than the GTX 780 to run. The difference is significant enough that the GTX 980 may have an adverse affect on your yearly electricity bills in comparison to the GTX 780.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 780 Asus Strix OC 6GB Edition is a special edition of NVIDIA's High-End GeForce GTX 780 6GB, created by Asus.

Overclock: Central Unit
The Central Unit now runs at 889MHz, instead of 863MHz and goes up to 941MHz, in Turbo Mode.

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer remain the same.

Cooling Solution
The reference NVIDIA Single-Fan Cooling System has been replaced by Asus's DirectCU II cooling technology which outperforms reference designs with an exclusive 10mm heatpipe that transports 40% more heat away from the GPU.

Performance
Benchmarks indicate a 2% performance over the reference GeForce GTX 780 6GB.
Overview
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.
