In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8950 (OEM) are massively better than the Nvidia GeForce 9800 GTX SLI.

The HD 8950 has a 175 MHz higher core clock speed and the same number of Texture Mapping Units as the 9800 GTX. This results in the HD 8950 providing 19.6 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 175 MHz higher core clock speed than the 9800 GTX and the same number of Render Output Units. This results in the HD 8950 providing 5.6 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 HD 8950 was released over three years more recently than the 9800 GTX, and so the HD 8950 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 9800 GTX when running the latest games.

The HD 8950 has 2048 MB more video memory than the 9800 GTX, 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 99.2 GB/sec greater memory bandwidth than the 9800 GTX, which means that the memory performance of the HD 8950 is massively better than the 9800 GTX.

The GeForce 9800 GTX SLI has 128 Shader Processing Units and the Radeon HD 8950 (OEM) has 1792. However, the actual shader performance of the 9800 GTX is 86 and the actual shader performance of the HD 8950 is 1658. The HD 8950 having 1572 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 9800 GTX.

The HD 8950 transistor size technology is 37 nm (nanometers) smaller than the 9800 GTX. This means that the HD 8950 is expected to run much cooler and achieve higher clock frequencies than the 9800 GTX.

The GeForce 9800 GTX SLI requires 280 Watts to run and the Radeon HD 8950 (OEM) requires 200 Watts. We would recommend a PSU with at least 600 Watts for the 9800 GTX and a PSU with at least 500 Watts for the HD 8950. The 9800 GTX requires 80 Watts more than the HD 8950 to run. The difference is significant enough that the 9800 GTX may have an adverse affect on your yearly electricity bills in comparison to the HD 8950.

GPU Mini Review

Mini ReviewThe SLI setup of GeForce 9800 GTX.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.
