In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6870 PowerColor 1GB Edition are significantly better than the AMD Radeon HD 6770 MSI MD 1GB.

The HD 6870 has a 100 MHz higher core clock speed and 16 more Texture Mapping Units than the HD 6770. This results in the HD 6870 providing 18.4 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 HD 6870 has a 100 MHz higher core clock speed and 16 more Render Output Units than the HD 6770. This results in the HD 6870 providing 16 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 6870 was released over a year more recently than the HD 6770, and so the HD 6870 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 Radeon HD 6870 PowerColor 1GB Edition and the Radeon HD 6770 MSI MD 1GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 6870 has 64 GB/sec greater memory bandwidth than the HD 6770, which means that the memory performance of the HD 6870 is much better than the HD 6770.

The Radeon HD 6870 PowerColor 1GB Edition has 1120 Shader Processing Units and the Radeon HD 6770 MSI MD 1GB has 800. However, the actual shader performance of the HD 6870 is 504 and the actual shader performance of the HD 6770 is 320. The HD 6870 having 184 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6870 delivers a massively smoother and more efficient experience when processing graphical data than the HD 6770.

We would recommend a PSU with at least 500 Watts for the HD 6870.

GPU Mini Review

Mini ReviewRadeon HD 6870 PowerColor 1GB Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
It has no new features and so it can be addressed as a renamed Radeon HD 6870. Therefore its performance is exactly like the standard's.
Radeon HD 6770 MSI MD 1GB is a special edition of Radeon HD 6770.
Compared to standard Radeon HD 6770 the performance is worse because both the core and memory clocks were reduced from 850MHz to 800MHz and from 1200MHz to 1100MHz, respectively.
There are no benchmarks available but we predict the performance is around 5% worse when compared to the standard AMD edition. The power consumption should also be lower.
