In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti Colorful iGame ARES X 2GB Edition are marginally better than the AMD Radeon HD 8950 (OEM).

The GTX 660 Ti has a 256 MHz higher core clock speed and the same number of Texture Mapping Units as the HD 8950. This results in the GTX 660 Ti providing 28.7 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 GTX 660 Ti has a 256 MHz higher core clock speed than the HD 8950, but the HD 8950 has 8 more Render Output Units than the GTX 660 Ti. As a result, the HD 8950 exhibits a 0.7 GPixel/s better Pixel Fill Rate than the GTX 660 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 8950 was released less than a year after the GTX 660 Ti, 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 HD 8950 has 1024 MB more video memory than the GTX 660 Ti, 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 76.6 GB/sec greater memory bandwidth than the GTX 660 Ti, which means that the memory performance of the HD 8950 is much better than the GTX 660 Ti.

The GeForce GTX 660 Ti Colorful iGame ARES X 2GB Edition has 1344 Shader Processing Units and the Radeon HD 8950 (OEM) has 1792. However, the actual shader performance of the GTX 660 Ti is 1610 and the actual shader performance of the HD 8950 is 1658. The HD 8950 having 48 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 8950 delivers a noticeably smoother and more efficient experience when processing graphical data than the GTX 660 Ti.

The GeForce GTX 660 Ti Colorful iGame ARES X 2GB Edition requires 150 Watts to run and the Radeon HD 8950 (OEM) requires 200 Watts. We would recommend a PSU with at least 450 Watts for the GTX 660 Ti and a PSU with at least 500 Watts for the HD 8950. The HD 8950 requires 50 Watts more than the GTX 660 Ti to run. The difference is significant enough that the HD 8950 may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 660 Ti.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 660 Ti Colorful iGame ARES X 2GB Edition is a special edition of NVIDIA's Performance GeForce GTX 660 Ti, created by Colorful.

Overclock: Central Unit
The Central Unit now runs at 1106MHz, instead of 915MHz and goes up to 1198MHz, instead of 980MHz, in Turbo Mode.

Overclock: Memory Clock
The Operating Memory Clock is now of 1702MHz instead of 1502MHz.

Benchmarks indicate a performance over the reference GeForce GTX 660 Ti.
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.
