In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 6GB are noticeably better than the Nvidia GeForce GTX 680 Galaxy Edition.

The GTX 680 has a 247 MHz higher core clock speed than the GTX 780, but the GTX 780 has 64 more Texture Mapping Units than the GTX 680. As a result, the GTX 780 exhibits a 23.6 GTexel/s better Texture Fill Rate than the GTX 680. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 680 has a 247 MHz higher core clock speed than the GTX 780, but the GTX 780 has 16 more Render Output Units than the GTX 680. As a result, the GTX 780 exhibits a 5.9 GPixel/s better Pixel Fill Rate than the GTX 680. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 780 was released over a year more recently than the GTX 680, and so the GTX 780 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 780 has 2048 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 780 also has superior memory performance overall.

The GTX 780 has 96.1 GB/sec greater memory bandwidth than the GTX 680, which means that the memory performance of the GTX 780 is massively better than the GTX 680.

The GeForce GTX 780 6GB has 2304 Shader Processing Units and the GeForce GTX 680 Galaxy Edition has 1536. However, the actual shader performance of the GTX 780 is 2078 and the actual shader performance of the GTX 680 is 1806. The GTX 780 having 272 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 780 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 680.

The GeForce GTX 780 6GB requires 250 Watts to run and the GeForce GTX 680 Galaxy Edition requires 195 Watts. We would recommend a PSU with at least 600 Watts for the GTX 780 and a PSU with at least 550 Watts for the GTX 680. The GTX 780 requires 55 Watts more than the GTX 680 to run. The difference is significant enough that the GTX 780 may have an adverse affect on your yearly electricity bills in comparison to the GTX 680.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 780 6GB is a High-End Graphics Card based on the first revision of the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It equips a GPU Codenamed GK110-301-B1 which has 12 SM activated and thus offers 1664 Shader Processing Units, 192 TMUs and 48 ROPs, on a 384-bit memory interface of fast GDDR5. The central unit runs at 863MHz and goes up to 902MHz.

Memory
The GPU accesses a 6GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is somewhat exaggerated. The Memory Clock Operates at 1502MHz.

Features
DirectX 11.2 Support (11.0 Hardware Default) and support for SLI, GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 250W, it requires at least a 600W PSU with one available 6-pin and 8-pin connectors.

Performance
Gaming benchmarks prove that at 2560x1600 GeForce GTX 780 6GB is around 10% faster than its original 3GB version.

System Suggestions
We recommend a very strong processor (Intel Core i7 Quad Core/AMD FX Eight Core) and 8GB of RAM for a system with GeForce GTX 780 6GB.
GeForce GTX 680 Galaxy Edition is a Special Edition of the powerful GeForce GTX 680. See the standard version for more information about it.
Compared to the standard version, GeForce GTX 680 Galaxy Edition features an increased core-clock that went from 1006MHz to 1110MHz and the turbo boost from 1100MHz to 1176MHz. The amount of memory was also increased from 2GB to 4GB, proving useful if gaming at high resolutions and using many image improving techniques, though we consider this excessive.
Expect a 9% performance boost when compared to the standard card.
