In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 950 Zotac AMP! 2GB Edition are marginally better than the AMD Radeon HD 8950 (OEM).

The GTX 950 has a 353 MHz higher core clock speed than the HD 8950, but the HD 8950 has 64 more Texture Mapping Units than the GTX 950. As a result, the HD 8950 exhibits a 37.5 GTexel/s better Texture Fill Rate than the GTX 950. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 950 has a 353 MHz higher core clock speed than the HD 8950 and the same number of Render Output Units. This results in the GTX 950 providing 11.3 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 GTX 950 was released over a year more recently than the HD 8950, and so the GTX 950 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 GTX 950, 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 127.7 GB/sec greater memory bandwidth than the GTX 950, which means that the memory performance of the HD 8950 is massively better than the GTX 950.

The GeForce GTX 950 Zotac AMP! 2GB Edition has 768 Shader Processing Units and the Radeon HD 8950 (OEM) has 1792. However, the actual shader performance of the GTX 950 is 1457 and the actual shader performance of the HD 8950 is 1658. The HD 8950 having 201 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 GTX 950.

The GeForce GTX 950 Zotac AMP! 2GB Edition requires 120 Watts to run and the Radeon HD 8950 (OEM) requires 200 Watts. We would recommend a PSU with at least 350 Watts for the GTX 950 and a PSU with at least 500 Watts for the HD 8950. The HD 8950 requires 80 Watts more than the GTX 950 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 GTX 950.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 950 Zotac AMP! 2GB Edition is a Special Edition of NVIDIA's Fast-Middle-Class GeForce GTX 950 2GB, created by Zotac.

Overclock: Central Unit
The Central Unit is now of 1203MHz, instead of 1024MHz, while the Boost Clock achieves 1405MHz, instead of 1188MHz.

Overclock: Memory Clock
The Operating Memory Clock has been increased from 1653MHz to 1755MHz.

Frame Buffer

Cooling Solution
Zotac Dual Fans.

Performance
Benchmarks Indicate a 12% Performance Boost over the Reference GeForce GTX 950 2GB.
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.

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.

GPU
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.

Memory
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.

Performance
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.
