In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 are significantly better than the AMD Radeon HD 6770 Crossfire.

The GeForce GTX 780 has a 13 MHz higher core clock speed and 112 more Texture Mapping Units than the HD 6770. This results in the GeForce GTX 780 providing 97.7 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 GeForce GTX 780 has a 13 MHz higher core clock speed and 16 more Render Output Units than the HD 6770. This results in the GeForce GTX 780 providing 14.2 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 GeForce GTX 780 was released over a year more recently than the HD 6770, and so the GeForce GTX 780 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6770.

The GeForce GTX 780 has 1024 MB more video memory than the HD 6770, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 780 also has superior memory performance overall.

The GeForce GTX 780 has 134.8 GB/sec greater memory bandwidth than the HD 6770, which means that the memory performance of the GeForce GTX 780 is massively better than the HD 6770.

The Radeon HD 6770 Crossfire has 1600 Shader Processing Units and the GeForce GTX 780 has 2304. However, the actual shader performance of the HD 6770 is 884 and the actual shader performance of the GeForce GTX 780 is 2078. The GeForce GTX 780 having 1194 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 780 delivers a massively smoother and more efficient experience when processing graphical data than the HD 6770.

The Radeon HD 6770 Crossfire requires 206 Watts to run and the GeForce GTX 780 requires 250 Watts. We would recommend a PSU with at least 600 Watts for the HD 6770 and a PSU with at least 600 Watts for the GeForce GTX 780. The GeForce GTX 780 requires 44 Watts more than the HD 6770 to run. The difference is significant enough that the GeForce GTX 780 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 6770.

GPU Mini Review

Mini ReviewRadeon HD 6770 Crossfire is a solution of two Radeon HD 6770 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 6770 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up around 79% better a single Radeon HD 6770 performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it might perform worse than a single Radeon HD 6770. Expect this combination to draw up to 216 Watt though the average power consumption should be slightly lower.
Most demanding games will run at the highest settings.
GeForce GTX 780 is a high-end graphics-card based on the 28nm, Kepler architecture.
It's based on the Kepler GK110 Core (same used on Titan) but with 12 SMX activated and therefore offers 2304 Shader Processing Units, 192 TMUs and 48 ROPs on a 384-bit memory interface of fast GDDR5. While the central unit runs at 863MHz and goes up to 902MHz in Turbo, the memory clock operates at 1502MHz. It consumes up to 250W.
Benchmarks indicate that its performance is up to 30% better than previous GeForce GTX 680 and thus allows even the most demanding games to be playable at the highest settings, at 1080p. With proper overclocking and cooling, it can surpass GeForce GTX Titan.
