In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 290 Gigabyte WindForce 3X OC Edition Crossfire are significantly better than the AMD Radeon HD 8950 (OEM).

The R9 290 has a 190 MHz higher core clock speed and 208 more Texture Mapping Units than the HD 8950. This results in the R9 290 providing 237.6 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 290 has a 190 MHz higher core clock speed and 96 more Render Output Units than the HD 8950. This results in the R9 290 providing 105.9 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 290 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.

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 R9 290 has 5120 MB more video memory than the HD 8950, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 290 also has superior memory performance overall.

The R9 290 has 400 GB/sec greater memory bandwidth than the HD 8950, which means that the memory performance of the R9 290 is massively better than the HD 8950.

The Radeon R9 290 Gigabyte WindForce 3X OC Edition Crossfire has 5120 Shader Processing Units and the Radeon HD 8950 (OEM) has 1792. However, the actual shader performance of the R9 290 is 4526 and the actual shader performance of the HD 8950 is 1658. The R9 290 having 2868 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 290 delivers a massively smoother and more efficient experience when processing graphical data than the HD 8950.

The Radeon HD 8950 (OEM) requires 200 Watts to run but there is no entry for the R9 290. We would recommend a PSU with at least 500 Watts for the HD 8950, but we do not have a recommended PSU wattage for the R9 290.

GPU Mini Review

Mini ReviewThe Crossfire setup of Radeon R9 290 Gigabyte WindForce 3X OC Edition.Overview
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.
