In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 680 Asus DirectCU II 4GB Edition are significantly better than the AMD Radeon HD 7850 XFX Core Edition.

The GTX 680 has a 146 MHz higher core clock speed and 64 more Texture Mapping Units than the HD 7850. This results in the GTX 680 providing 73.8 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 680 has a 146 MHz higher core clock speed than the HD 7850 and the same number of Render Output Units. This results in the GTX 680 providing 4.7 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 GTX 680 was released less than a year after the HD 7850, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 680 has 3072 MB more video memory than the HD 7850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 680 also has superior memory performance overall.

The GTX 680 has 32.3 GB/sec greater memory bandwidth than the HD 7850, which means that the memory performance of the GTX 680 is noticeably better than the HD 7850.

The GeForce GTX 680 Asus DirectCU II 4GB Edition has 1536 Shader Processing Units and the Radeon HD 7850 XFX Core Edition has 1024. However, the actual shader performance of the GTX 680 is 1625 and the actual shader performance of the HD 7850 is 749. The GTX 680 having 876 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 680 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7850.

The GeForce GTX 680 Asus DirectCU II 4GB Edition requires 225 Watts to run but there is no entry for the Radeon HD 7850 XFX Core Edition. We would recommend a PSU with at least 550 Watts for the GTX 680 and a PSU with at least 500 Watts for the HD 7850. The GTX 680 has been recommended a PSU with 50 Watts more than the HD 7850. The difference is significant enough that the GTX 680 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 7850.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 680 Asus DirectCU II 4GB Edition is a Special Edition of NVIDIA's High-End GeForce GTX 680, created by Asus.

Overclock: Central Unit

Overclock: Memory Clock

Frame Buffer
The Frame Buffer was doubled to 4GB. This would prove useful in a few circumstances because some modern 3D Games require 4GB of Memory for Textures.
However, because the GPU itself is too weak to work under other circumstances in which 4GB of Memory are needed - such as 1600p Gaming, a Larger Frame Buffer is mostly a Gimmick.

Cooling Solution
DirectCU II: DirectCU thermal design utilizes direct contact copper heatpipes so heat is dissipated efficiently, delivering a 20% cooler and vastly quieter performance than reference..

Benchmarks indicate no performance over the reference GeForce GTX 680.
Radeon HD 7850 XFX Core Edition is a special edition of the powerful Radeon HD 7850. See the standard version for more information about it.
This edition features a special cooling system that allows twice as much heat dissipation when compared to the reference AMD cooling system but its performance is still the same, as there's no over-clocking out of the box.
