In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6950 PowerColor 2GB Edition are significantly better than the Nvidia GeForce GTX 550 Ti WindForce Edition.

The GTX 550 Ti has a 170 MHz higher core clock speed than the HD 6950, but the HD 6950 has 56 more Texture Mapping Units than the GTX 550 Ti. As a result, the HD 6950 exhibits a 39.4 GTexel/s better Texture Fill Rate than the GTX 550 Ti. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 550 Ti has a 170 MHz higher core clock speed than the HD 6950, but the HD 6950 has 8 more Render Output Units than the GTX 550 Ti. As a result, the HD 6950 exhibits a 2.3 GPixel/s better Pixel Fill Rate than the GTX 550 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 550 Ti was released less than a year after the HD 6950, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 6950 has 1024 MB more video memory than the GTX 550 Ti, 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 HD 6950 has 61.6 GB/sec greater memory bandwidth than the GTX 550 Ti, which means that the memory performance of the HD 6950 is much better than the GTX 550 Ti.

The Radeon HD 6950 PowerColor 2GB Edition has 1408 Shader Processing Units and the GeForce GTX 550 Ti WindForce Edition has 192. However, the actual shader performance of the HD 6950 is 563 and the actual shader performance of the GTX 550 Ti is 372. The HD 6950 having 191 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6950 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 550 Ti.

The Radeon HD 6950 PowerColor 2GB Edition requires 200 Watts to run but there is no entry for the GeForce GTX 550 Ti WindForce Edition. We would recommend a PSU with at least 500 Watts for the HD 6950 and a PSU with at least 400 Watts for the GTX 550 Ti. The HD 6950 has been recommended a PSU with 100 Watts more than the GTX 550 Ti. The difference is significant enough that the HD 6950 may have an adverse affect on your yearly electricity bills in comparison to the GTX 550 Ti.

GPU Mini Review

Mini ReviewRadeon HD 6950 PowerColor 2GB Edition is a special editon of the high-end Radeon HD 6950.
The only new feature is a new Cooling System. Therefore, Radeon HD 6950 PowerColor 2GB Edition delivers the same performance the reference Radeon HD 6950 does.
GeForce GTX 550 Ti WindForce Edition is a special edition of the upper-middle-class GeForce GTX 550 Ti. See the standard edition's page for more information.
The new features include an increase in the clock from 900MHz to 970MHz and a new cooling system.
Benchmarks indicate a 4.5% performance boost when compared to the reference card..
Some modern demanding games will run at the highest settings using a 1080p resolution but the largest part will have to be played with a 720p resolution to be played optimally.
This Graphics Card needs to be paired with a decent Quad Core CPU.
