In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 VTX3D 3GB Boost X-Edition are massively better than the AMD Radeon R7 250 PowerColor OC 1GB Edition.

The R7 250 has a 170 MHz higher core clock speed than the HD 7950, but the HD 7950 has 88 more Texture Mapping Units than the R7 250. As a result, the HD 7950 exhibits a 73.4 GTexel/s better Texture Fill Rate than the R7 250. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 250 has a 170 MHz higher core clock speed than the HD 7950, but the HD 7950 has 24 more Render Output Units than the R7 250. As a result, the HD 7950 exhibits a 19.8 GPixel/s better Pixel Fill Rate than the R7 250. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 250 was released over a year more recently than the HD 7950, and so the R7 250 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7950.

The HD 7950 has 2048 MB more video memory than the R7 250, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7950 also has superior memory performance overall.

The HD 7950 has 166.4 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the HD 7950 is massively better than the R7 250.

The Radeon R7 250 PowerColor OC 1GB Edition has 384 Shader Processing Units and the Radeon HD 7950 VTX3D 3GB Boost X-Edition has 1792. However, the actual shader performance of the R7 250 is 359 and the actual shader performance of the HD 7950 is 1417. The HD 7950 having 1058 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a massively smoother and more efficient experience when processing graphical data than the R7 250.

The Radeon R7 250 PowerColor OC 1GB Edition requires 75 Watts to run but there is no entry for the Radeon HD 7950 VTX3D 3GB Boost X-Edition. We would recommend a PSU with at least 400 Watts for the R7 250 and a PSU with at least 500 Watts for the HD 7950. The HD 7950 has been recommended a PSU with 100 Watts more than the R7 250. The difference is significant enough that the HD 7950 may have an adverse affect on your yearly electricity bills in comparison to the R7 250.
