In terms of overall gaming performance, the graphical capabilities of the HD 6950 and the HD 7850 are equal.

The HD 7850 has a 60 MHz higher core clock speed than the HD 6950, but the HD 6950 has 24 more Texture Mapping Units than the HD 7850. As a result, the HD 6950 exhibits a 15.4 GTexel/s better Texture Fill Rate than the HD 7850. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7850 has a 60 MHz higher core clock speed than the HD 6950 and the same number of Render Output Units. This results in the HD 7850 providing 1.9 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 HD 7850 was released over a year more recently than the HD 6950, and so the HD 7850 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6950.

The HD 6950 has 1024 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 HD 6950 also has superior memory performance overall.

The memory bandwidth of the Radeon HD 6950 XFX 2GB Edition and the Radeon HD 7850 XFX Core Edition are the same, which means the HD 6950 and the HD 7850 have equal limitations when it comes to graphical data transfer.

The Radeon HD 6950 XFX 2GB Edition has 1408 Shader Processing Units and the Radeon HD 7850 XFX Core Edition has 1024. However, the actual shader performance of the HD 6950 is 563 and the actual shader performance of the HD 7850 is 749. The HD 7850 having 186 better shader performance is not particularly notable, as altogether the HD 6950 performs better when taking into account other relevant data.

The HD 7850 transistor size technology is 12 nm (nanometers) smaller than the HD 6950. This means that the HD 7850 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6950. While they exhibit similar graphical performance, the HD 7850 should consume less power than the HD 6950.

The Radeon HD 6950 XFX 2GB Edition requires 200 Watts to run but there is no entry for the Radeon HD 7850 XFX Core Edition. We would recommend a PSU with at least 500 Watts for the HD 6950 and a PSU with at least 500 Watts for the HD 7850. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

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.
