In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 Gainward Phantom GLH Edition are significantly better than the AMD Radeon HD 6850 Crossfire.

The GTX 780 has a 205 MHz higher core clock speed and 96 more Texture Mapping Units than the HD 6850. This results in the GTX 780 providing 113.8 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 GTX 780 has a 205 MHz higher core clock speed than the HD 6850, but the HD 6850 has 16 more Render Output Units than the GTX 780. As a result, the HD 6850 exhibits a 2.6 GPixel/s better Pixel Fill Rate than the GTX 780. 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 HD 6850, 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 HD 6850.

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 1024 MB more video memory than the HD 6850, 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 32.4 GB/sec greater memory bandwidth than the HD 6850, which means that the memory performance of the GTX 780 is noticeably better than the HD 6850.

The GeForce GTX 780 Gainward Phantom GLH Edition has 2304 Shader Processing Units and the Radeon HD 6850 Crossfire has 1920. However, the actual shader performance of the GTX 780 is 2380 and the actual shader performance of the HD 6850 is 967. The GTX 780 having 1413 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 HD 6850.

The GTX 780 transistor size technology is 12 nm (nanometers) smaller than the HD 6850. This means that the GTX 780 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6850.

We would recommend a PSU with at least 600 Watts for the GTX 780.

GPU Mini Review

Mini ReviewGeForce GTX 780 Gainward Phantom GLH Edition is a special edition of the high-end GeForce GTX 780.
This edition comes with a custom triple fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 863MHz to 980MHz while its boost clock is now of 1033MHz. The memory clock was also increased to 1550MHz.
Benchmarks indicate a 8% performance boost when compared to the reference card.
Radeon HD 6850 Crossfire is a solution of two Radeon HD 6850 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 6850 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 to 31% better than a single Radeon HD 6850 performing by itself but it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 6850. Expect this combination to draw up to 254 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
