In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8950 (OEM) are massively better than the AMD Radeon R7 250E Sapphire Ultimate 1GB Edition.

The HD 8950 has a 50 MHz higher core clock speed and 80 more Texture Mapping Units than the R7 250E. This results in the HD 8950 providing 69.6 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 8950 has a 50 MHz higher core clock speed and 16 more Render Output Units than the R7 250E. This results in the HD 8950 providing 14.4 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 R7 250E was released less than a year after the HD 8950, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 8950 has 2048 MB more video memory than the R7 250E, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 8950 also has superior memory performance overall.

The HD 8950 has 168 GB/sec greater memory bandwidth than the R7 250E, which means that the memory performance of the HD 8950 is massively better than the R7 250E.

The Radeon R7 250E Sapphire Ultimate 1GB Edition has 512 Shader Processing Units and the Radeon HD 8950 (OEM) has 1792. However, the actual shader performance of the R7 250E is 348 and the actual shader performance of the HD 8950 is 1658. The HD 8950 having 1310 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 8950 delivers a massively smoother and more efficient experience when processing graphical data than the R7 250E.

The Radeon R7 250E Sapphire Ultimate 1GB Edition requires 75 Watts to run and the Radeon HD 8950 (OEM) requires 200 Watts. We would recommend a PSU with at least 400 Watts for the R7 250E and a PSU with at least 500 Watts for the HD 8950. The HD 8950 requires 125 Watts more than the R7 250E to run. The difference is significant enough that the HD 8950 may have an adverse affect on your yearly electricity bills in comparison to the R7 250E.

Benchmarks Indicate no Performance Boost over the Reference Radeon R7 250E.
Radeon HD 8950 (OEM) is an OEM Only, High-End Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.

It equips a GPU Codenamed Tahiti PRO2 which has 28 Compute Units activated and thus offers 1792 Shader Processing Units, 112 TMUs and 32 ROPs. The Central Unit is clocked at 850MHz and goes up to 925MHz, in Turbo Mode.

The GPU accesses a 3GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1250MHz.

Power Consumption
With a rated board TDP of 200W, it requires at least a 500W PSU with two available 6-pin connectors.

Radeon HD 8950 (OEM) is a Direct Rebrand of Radeon HD 7950 Boost Edition and performs exactly like it.

System Suggestions
Radeon HD 8950 (OEM) is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for Optimal Performance.
