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 7750 VTX3D 1GB DDR3 Edition.

The HD 6870 has a 100 MHz higher core clock speed and 24 more Texture Mapping Units than the HD 7750. This results in the HD 6870 providing 24.8 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 HD 6870 has a 100 MHz higher core clock speed and 16 more Render Output Units than the HD 7750. 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 7750 was released less than a year after the HD 6870, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 6870 PowerColor 1GB Edition and the Radeon HD 7750 VTX3D 1GB DDR3 Edition 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 108.8 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the HD 6870 is massively better than the HD 7750.

The Radeon HD 6870 PowerColor 1GB Edition has 1120 Shader Processing Units and the Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512. However, the actual shader performance of the HD 6870 is 504 and the actual shader performance of the HD 7750 is 348. The HD 6870 having 156 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 7750.

The HD 7750 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

We would recommend a PSU with at least 500 Watts for the HD 6870 and a PSU with at least 400 Watts for the HD 7750. The HD 6870 has been recommended a PSU with 100 Watts more than the HD 7750. The difference is significant enough that the HD 6870 may have an adverse affect on your yearly electricity bills in comparison to the HD 7750.

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 7750 VTX3D 1GB DDR3 Edition is a special edition of the fast-middle-class Radeon HD 7750 1GB DDR3.
This version has no new features (when compared to the DDR3 version) and so it performs exactly like it.
