In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 285 Sapphire ITX Compact 2GB Edition are marginally better than the AMD Radeon HD 8950 (OEM).

The R9 285 has a 68 MHz higher core clock speed and the same number of Texture Mapping Units as the HD 8950. This results in the R9 285 providing 7.6 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 R9 285 has a 68 MHz higher core clock speed than the HD 8950 and the same number of Render Output Units. This results in the R9 285 providing 2.2 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 R9 285 was released over a year more recently than the HD 8950, and so the R9 285 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 8950.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The HD 8950 has 1024 MB more video memory than the R9 285, 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 8950 has 64 GB/sec greater memory bandwidth than the R9 285, which means that the memory performance of the HD 8950 is much better than the R9 285.

Both the Radeon R9 285 Sapphire ITX Compact 2GB Edition and the Radeon HD 8950 (OEM) have 1792 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the HD 8950 is 1658 and by the R9 285 is 1658. Knowing that the shader performance of the HD 8950 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon R9 285 Sapphire ITX Compact 2GB Edition requires 190 Watts to run and the Radeon HD 8950 (OEM) requires 200 Watts. We would recommend a PSU with at least 500 Watts for the R9 285 and a PSU with at least 500 Watts for the HD 8950. The HD 8950 requires 10 Watts more than the R9 285 to run. The difference is not significant enough for the HD 8950 to have a noticeably larger impact on your yearly electricity bills than the R9 285.

GPU Mini Review

Mini ReviewRadeon R9 285 Sapphire ITX Compact 2GB Edition is a special edition of the high-end Radeon R9 285 2GB.

This edition has been modified for small form factor PC Systems, by featuring a smaller PCB.

It offers no overclock out of the box and therefore it performs like the reference AMD Radeon R9 285 2GB.
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.
