In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6950 PowerColor 1GB Edition are noticeably better than the AMD Radeon R7 260.

The Radeon R7 260 has a 200 MHz higher core clock speed than the HD 6950, but the HD 6950 has 40 more Texture Mapping Units than the Radeon R7 260. As a result, the HD 6950 exhibits a 22.4 GTexel/s better Texture Fill Rate than the Radeon R7 260. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon R7 260 has a 200 MHz higher core clock speed than the HD 6950, but the HD 6950 has 16 more Render Output Units than the Radeon R7 260. As a result, the HD 6950 exhibits a 9.6 GPixel/s better Pixel Fill Rate than the Radeon R7 260. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 260 was released over three years more recently than the HD 6950, and so the Radeon R7 260 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 6950 when running the latest games.

The Radeon R7 260 has 1024 MB more video memory than the HD 6950, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 6950 has 64 GB/sec greater memory bandwidth than the Radeon R7 260, which means that the memory performance of the HD 6950 is much better than the Radeon R7 260.

The Radeon HD 6950 PowerColor 1GB Edition has 1408 Shader Processing Units and the Radeon R7 260 has 768. However, the actual shader performance of the HD 6950 is 563 and the actual shader performance of the Radeon R7 260 is 653. The Radeon R7 260 having 90 better shader performance is not particularly notable, as altogether the HD 6950 performs better when taking into account other relevant data.

The Radeon R7 260 transistor size technology is 12 nm (nanometers) smaller than the HD 6950. This means that the Radeon R7 260 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6950.

The Radeon HD 6950 PowerColor 1GB Edition requires 200 Watts to run and the Radeon R7 260 requires 95 Watts. We would recommend a PSU with at least 500 Watts for the HD 6950 and a PSU with at least 450 Watts for the Radeon R7 260. The HD 6950 requires 105 Watts more than the Radeon R7 260 to run. The difference is significant enough that the HD 6950 may have an adverse affect on your yearly electricity bills in comparison to the Radeon R7 260.

GPU Mini Review

Mini ReviewRadeon HD 6950 PowerColor 1GB 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 1GB Edition delivers the same performance the reference Radeon HD 6950 does.
Radeon R7 260 is a fast-middle-class graphics card based on the Second Revision of the GCN architecture. It packs a Core codenamed Bonaire PRO.
The Bonaire PRO is a cut-down version of the Bonaire XT Core used on Radeon HD 7790. It comes with 14 Compute Units and thus offers 768 Shader Processing Units, 48 TMUs and 16 ROPs. This, on a 128-bit memory interface of fast GDDR5. Compared to the Bonaire XT Core, it has support for DirectX 11.2 and has support for AMD's TrueAudio Technology.
Benchmarks indicate its performance is around 10% slower than Radeon HD 7790 and a little over that when taking Radeon R7 260X as a reference.
The card proves to be very inefficient seeing as it has a higher rated TDP board than Radeon HD 7790 and its release price of $109 makes Radeon HD 7850 a better option.
