In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 SLI are significantly 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 256 more Texture Mapping Units than the GTX 680. As a result, the GTX 780 exhibits a 189.3 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 64 more Render Output Units than the GTX 680. As a result, the GTX 780 exhibits a 47.3 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 384.5 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 SLI has 4608 Shader Processing Units and the GeForce GTX 680 Galaxy Edition has 1536. However, the actual shader performance of the GTX 780 is 4156 and the actual shader performance of the GTX 680 is 1806. The GTX 780 having 2350 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 SLI requires 500 Watts to run and the GeForce GTX 680 Galaxy Edition requires 195 Watts. We would recommend a PSU with at least 750 Watts for the GTX 780 and a PSU with at least 550 Watts for the GTX 680. The GTX 780 requires 305 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 ReviewGeForce GTX 780 SLI is a combination of 2 GeForce GTX 780 put together using NVIDIA's SLI technology.
Together, this combination offers 4608 Shader Processing Units, 384 TMUs and 96 ROPs. This, on a 384-bit memory interface, per card, of fast GDDR5. While the central unit runs at 863MHz and goes up to 902MHz, in Turbo Mode, the memory clock operates at 1502MHz.
Best case scenario, this combination surpasses considerably a single GeForce GTX 690 but ultimately, its performance depends on the driver support and on the 3D application.
Therefore, and paired with a powerful processor, all demanding games are playable at the highest settings. Still, this combination might surpass the 500W barrier of TDP and so it will require a powerful PSU.
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.
