In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 970 4GB SLI are significantly better than the Nvidia GeForce GTX 780 Gainward Phantom GLH Edition.

The GTX 970 has a 70 MHz higher core clock speed and 16 more Texture Mapping Units than the GTX 780. This results in the GTX 970 providing 30.2 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 970 has a 70 MHz higher core clock speed and 80 more Render Output Units than the GTX 780. This results in the GTX 970 providing 87.4 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 970 was released over a year more recently than the GTX 780, and so the GTX 970 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 780.

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 970 has 5120 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 970 also has superior memory performance overall.

The GTX 970 has 160.4 GB/sec greater memory bandwidth than the GTX 780, which means that the memory performance of the GTX 970 is massively better than the GTX 780.

The GeForce GTX 970 4GB SLI has 3328 Shader Processing Units and the GeForce GTX 780 Gainward Phantom GLH Edition has 2304. However, the actual shader performance of the GTX 970 is 5293 and the actual shader performance of the GTX 780 is 2380. The GTX 970 having 2913 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 970 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 780.

The GeForce GTX 970 4GB SLI requires 325 Watts to run but there is no entry for the GeForce GTX 780 Gainward Phantom GLH Edition. We would recommend a PSU with at least 750 Watts for the GTX 970 and a PSU with at least 600 Watts for the GTX 780. The GTX 970 has been recommended a PSU with 150 Watts more than the GTX 780. The difference is significant enough that the GTX 970 may have an adverse affect on your yearly electricity bills in comparison to the GTX 780.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 970 4GB SLI is a solution of two GeForce GTX 970 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 3328 Shader Processing Units, 208 TMUs and 128 ROPs, on a 512-bit memory interface of fast GDDR5. The central unit runs at 1050MHz and goes up to 1178MHz, 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 970 4GB SLI is over 25% faster than Radeon HD 7990 and almost as fast as 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 970 4GB SLI.
GeForce GTX 780 Gainward Phantom GLH Edition is a special edition of the high-end GeForce GTX 780.
This edition comes with a custom triple fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 863MHz to 980MHz while its boost clock is now of 1033MHz. The memory clock was also increased to 1550MHz.
Benchmarks indicate a 8% performance boost when compared to the reference card.
