In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 680 are massively better than the AMD Radeon HD 6850 XFX Black Edition.

The GeForce GTX 680 has a 206 MHz higher core clock speed and 80 more Texture Mapping Units than the HD 6850. This results in the GeForce GTX 680 providing 90.4 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 680 has a 206 MHz higher core clock speed than the HD 6850 and the same number of Render Output Units. This results in the GeForce GTX 680 providing 6.6 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 680 was released over a year more recently than the HD 6850, and so the GeForce GTX 680 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6850.

The GeForce GTX 680 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 GeForce GTX 680 also has superior memory performance overall.

The GeForce GTX 680 has 57.9 GB/sec greater memory bandwidth than the HD 6850, which means that the memory performance of the GeForce GTX 680 is much better than the HD 6850.

The Radeon HD 6850 XFX Black Edition has 960 Shader Processing Units and the GeForce GTX 680 has 1536. However, the actual shader performance of the HD 6850 is 384 and the actual shader performance of the GeForce GTX 680 is 1625. The GeForce GTX 680 having 1241 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 680 delivers a massively smoother and more efficient experience when processing graphical data than the HD 6850.

The GeForce GTX 680 transistor size technology is 12 nm (nanometers) smaller than the HD 6850. This means that the GeForce GTX 680 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6850.

The GeForce GTX 680 requires 195 Watts to run but there is no entry for the HD 6850. We would recommend a PSU with at least 500 Watts for the HD 6850 and a PSU with at least 550 Watts for the GeForce GTX 680. The GeForce GTX 680 has been recommended a PSU with 50 Watts more than the HD 6850. The difference is significant enough that the GeForce GTX 680 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 6850.

GPU Mini Review

Mini ReviewRadeon HD 6850 XFX Black Edition is a special edition of the Radeon HD 6850. See the page of the standard edition for more information about it.
The new features include increases in the core and memory clocks that went from 775MHz to 800MHz and from 1000MHz to 1050MHz, respectively. Features that make it more energy efficient and a better cooling system are also included.
The performance increase is about 3% according to benchmarks and so and so even the most demanding games are playable at high settings but not with extreme resolutions and extreme technologies due to the limited memory size.
GeForce GTX 680 is a high-end Graphics Card based on the 28nm, Kepler architecture.
The Kepler architecture allows more SPUs but the Fermi SPUs (used on the 400 & 500 Series) are clocked twice as fast as the Kepler architecture. Therefore, don't let the large amount of Pipelines fool you, as the 1536 Pipelines are equivalent to 768 Pipelines, of the Fermi architecture.
GeForce GTX 680 features a 1006Mhz core-clock that can automatically set itself to 1058Mhz using a technology similar to the one used on Intel GPUs. Another huge surprise is the TDP that went from 244 Watts, to just 195 Watts, as two SPUs of the Kepler architecture consume 10% less power. However, the amount was doubled and so the power save is not as high as it could have been.
GeForce GTX 680 was the fastest single GPU of the world until Radeon HD 7970 GHz Edition was released.
All games will run on the maximum settings smoothly.
