In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6950 Gigabyte WindForce 3X OC 1GB Edition are significantly better than the AMD Radeon R7 250X.

The Radeon R7 250X has a 80 MHz higher core clock speed than the HD 6950, but the HD 6950 has 48 more Texture Mapping Units than the Radeon R7 250X. As a result, the HD 6950 exhibits a 38.6 GTexel/s better Texture Fill Rate than the Radeon R7 250X. 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 250X has a 80 MHz higher core clock speed than the HD 6950, but the HD 6950 has 16 more Render Output Units than the Radeon R7 250X. As a result, the HD 6950 exhibits a 12.6 GPixel/s better Pixel Fill Rate than the Radeon R7 250X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 250X was released over three years more recently than the HD 6950, and so the Radeon R7 250X 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 250X 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, overall, the HD 6950 has superior memory performance.

The HD 6950 has 88 GB/sec greater memory bandwidth than the Radeon R7 250X, which means that the memory performance of the HD 6950 is much better than the Radeon R7 250X.

The Radeon HD 6950 Gigabyte WindForce 3X OC 1GB Edition has 1408 Shader Processing Units and the Radeon R7 250X has 640. However, the actual shader performance of the HD 6950 is 612 and the actual shader performance of the Radeon R7 250X is 517. The HD 6950 having 95 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 Radeon R7 250X.

The Radeon R7 250X transistor size technology is 12 nm (nanometers) smaller than the HD 6950. This means that the Radeon R7 250X is expected to run slightly cooler and achieve higher clock frequencies than the HD 6950.

The Radeon HD 6950 Gigabyte WindForce 3X OC 1GB Edition requires 200 Watts to run and the Radeon R7 250X requires 80 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 250X. The HD 6950 requires 120 Watts more than the Radeon R7 250X 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 250X.

Performance
Benchmarks Indicate a 4% Performance Boost over the Reference Radeon HD 6950.
Radeon R7 250X is a fast-middle-class Graphics Card based on the Graphics Core Next architecture. It offers the Cape Verde XT GPU.
The Cape Verde XT Core is a GCN 1.1 GPU and was first seen on Radeon HD 7770 and then re-used in the OEM only Radeon HD 8760.
It offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bits memory interface of fast GDDR5.
Radeon R7 250X comes clocked at 950MHz (though there might be some 1GHz versions) and has its operating memory clock set at 1125MHz. The rated TDP board is of 80W and the release price around $99.
This card should come in 1GB and 2GB versions, though both will offer the same performance.
Its performance has proven to be exactly like Radeon HD 7770 GHz Edition (if clocked at 1GHz) and thus this card is not suited for 1080p gaming but it can handle 720p with ease. The 950MHz versions will be around 3% slower.
