In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8950 (OEM) are massively better than the Nvidia GeForce 8800 Ultra.

The HD 8950 has a 238 MHz higher core clock speed and 80 more Texture Mapping Units than the GeForce 8800 Ultra. This results in the HD 8950 providing 75.6 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 238 MHz higher core clock speed and 8 more Render Output Units than the GeForce 8800 Ultra. This results in the HD 8950 providing 12.5 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 GeForce 8800 Ultra, 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 GeForce 8800 Ultra when running the latest games.

The HD 8950 has 2304 MB more video memory than the GeForce 8800 Ultra, 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 136.3 GB/sec greater memory bandwidth than the GeForce 8800 Ultra, which means that the memory performance of the HD 8950 is massively better than the GeForce 8800 Ultra.

The Radeon HD 8950 (OEM) has 1792 Shader Processing Units and the GeForce 8800 Ultra has 128. However, the actual shader performance of the HD 8950 is 1658 and the actual shader performance of the GeForce 8800 Ultra is 196. The HD 8950 having 1462 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 GeForce 8800 Ultra.

The HD 8950 transistor size technology is 62 nm (nanometers) smaller than the GeForce 8800 Ultra. This means that the HD 8950 is expected to run massively cooler and achieve higher clock frequencies than the GeForce 8800 Ultra.

The Radeon HD 8950 (OEM) requires 200 Watts to run and the GeForce 8800 Ultra requires 172 Watts. We would recommend a PSU with at least 500 Watts for the HD 8950 and a PSU with at least 500 Watts for the GeForce 8800 Ultra. The HD 8950 requires 28 Watts more than the GeForce 8800 Ultra 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 GeForce 8800 Ultra.

GPU Mini Review

Mini ReviewOverview
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.
GeForce 8800 Ultra is a high-end GFX and the most powerful GPU of the GeForce 8000 Series, based on the 90nm variant of the first-shader unified architecture.
It's based on the G80 Core (same used on 8800 GTX) and offers 128 Shader Processing Units, 32 TMUs and 24 ROPs, on a 384-bit memory interface of GDDR3. The central unit runs at 612MHz and the memory clock operates 1080MHz. It will consume no more than 172 Watt.
It can be addressed as a further clocked GeForce 8800 GTX and is known to heat a lot. As the most powerful GPU in 2007, even today's modern demanding games can be played at medium or high settings smoothly. However, DirectX 11 based games aren't supported.
