In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 6GB are noticeably better than the Nvidia GeForce GTX 770 PNY Enthusiast 4GB OC Edition.

The GTX 770 has a 196 MHz higher core clock speed than the GTX 780, but the GTX 780 has 64 more Texture Mapping Units than the GTX 770. As a result, the GTX 780 exhibits a 30.1 GTexel/s better Texture Fill Rate than the GTX 770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 770 has a 196 MHz higher core clock speed than the GTX 780, but the GTX 780 has 16 more Render Output Units than the GTX 770. As a result, the GTX 780 exhibits a 7.5 GPixel/s better Pixel Fill Rate than the GTX 770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 780 was released less than a year after the GTX 770, and so they are likely to have similar driver support for optimizing performance when running the latest games.

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 770, 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 64 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the GTX 780 is much better than the GTX 770.

The GeForce GTX 780 6GB has 2304 Shader Processing Units and the GeForce GTX 770 PNY Enthusiast 4GB OC Edition has 1536. However, the actual shader performance of the GTX 780 is 2078 and the actual shader performance of the GTX 770 is 1706. The GTX 780 having 372 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 770.

The GeForce GTX 780 6GB requires 250 Watts to run and the GeForce GTX 770 PNY Enthusiast 4GB OC Edition requires 230 Watts. We would recommend a PSU with at least 600 Watts for the GTX 780 and a PSU with at least 600 Watts for the GTX 770. The GTX 780 requires 20 Watts more than the GTX 770 to run. The difference is not significant enough for the GTX 780 to have a noticeably larger impact on your yearly electricity bills than the GTX 770.

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 770 PNY Enthusiast 4GB OC Edition is a special edition of GeForce GTX 770.
This edition comes with a custom dual fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 770 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 1046MHz to 1059MHz while its boost clock is now of 1111MHz and its frame buffer was doubled to 4GB, which will prove useless. The memory clock was left untouched.
Benchmarks indicate a 4% performance boost when compared to the reference card.
