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

The GTX 970 has a 96 MHz higher core clock speed and 16 more Texture Mapping Units than the GTX 780. This results in the GTX 970 providing 35.6 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 970 has a 96 MHz higher core clock speed and 64 more Render Output Units than the GTX 780. This results in the GTX 970 providing 73.5 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 Zotac 4GB Edition 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 5463 and the actual shader performance of the GTX 780 is 2380. The GTX 970 having 3083 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.

We would recommend a PSU with at least 600 Watts for the GTX 780, but we do not have a recommended PSU wattage for the GTX 970.

GPU Mini Review

Mini ReviewThe SLI setup of GeForce GTX 970 Zotac 4GB Edition.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.
