In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 Asus ROG Poseidon 4GB Edition are noticeably better than the Nvidia GeForce GTX 780 Galaxy HOF 3GB Edition.

The GTX 980 has a 172 MHz higher core clock speed than the GTX 780, but the GTX 780 has 64 more Texture Mapping Units than the GTX 980. As a result, the GTX 780 exhibits a 42.4 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 172 MHz higher core clock speed and 16 more Render Output Units than the GTX 780. This results in the GTX 980 providing 27.1 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 over a year more recently than the GTX 780, 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 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 980 has 1024 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 780 has 64 GB/sec greater memory bandwidth than the GTX 980, which means that the memory performance of the GTX 780 is much better than the GTX 980.

The GeForce GTX 980 Asus ROG Poseidon 4GB Edition has 2048 Shader Processing Units and the GeForce GTX 780 Galaxy HOF 3GB Edition has 2304. However, the actual shader performance of the GTX 980 is 3536 and the actual shader performance of the GTX 780 is 2438. The GTX 980 having 1098 better shader performance is not particularly notable, as altogether the GTX 780 performs better when taking into account other relevant data.

The GeForce GTX 980 Asus ROG Poseidon 4GB Edition requires 300 Watts to run and the GeForce GTX 780 Galaxy HOF 3GB Edition requires 250 Watts. We would recommend a PSU with at least 600 Watts for the GTX 980 and a PSU with at least 600 Watts for the GTX 780. The GTX 980 requires 50 Watts more than the GTX 780 to run. The difference is significant enough that the GTX 980 may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 780.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 980 Asus ROG Poseidon 4GB Edition is a special edition of NVIDIA's high-end GeForce GTX 980 4GB.

Overclock Out of The Box
The Central Unit now runs at 1178MHz, instead of 1141MHz. Boost Clock is now of 1279MHz, instead of 1216MHz. Memory Clock was left untouched.

Cooling Solution
The reference NVIDIA Single-Fan Cooling System has been replaced by Asus's DirectCU II H20 Dual Fan Cooling Solution. This means the card runs cooler under load.

Benchmarks indicate a 4% performance over the reference GeForce GTX 980 4GB.
GeForce GTX 780 Galaxy HOF 3GB Edition is a special edition of the high-end GeForce GTX 780.
This edition comes with a custom double fan cooling solution which will allow a reasonable performance boost from the start, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 863MHz to 1006MHz while its boost clock is now of 1058MHz. The memory clock was left untouched.
Benchmarks indicate a 11% performance boost when compared to the reference card and so this edition performs slightly better than GeForce GTX Titan.
