Game Radeon HD 6950 XFX Dual-Fan 2GB Edition GeForce GTX 260

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6950 XFX Dual-Fan 2GB Edition are significantly better than the Nvidia GeForce GTX 260.

The HD 6950 has a 224 MHz higher core clock speed and 24 more Texture Mapping Units than the GeForce GTX 260. This results in the HD 6950 providing 33.5 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 6950 has a 224 MHz higher core clock speed and 4 more Render Output Units than the GeForce GTX 260. This results in the HD 6950 providing 9.5 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 6950 was released over a year more recently than the GeForce GTX 260, and so the HD 6950 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 260.

The HD 6950 has 1152 MB more video memory than the GeForce GTX 260, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 6950 also has superior memory performance overall.

The HD 6950 has 48.1 GB/sec greater memory bandwidth than the GeForce GTX 260, which means that the memory performance of the HD 6950 is noticeably better than the GeForce GTX 260.

The Radeon HD 6950 XFX Dual-Fan 2GB Edition has 1408 Shader Processing Units and the GeForce GTX 260 has 192. However, the actual shader performance of the HD 6950 is 563 and the actual shader performance of the GeForce GTX 260 is 254. The HD 6950 having 309 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6950 delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GTX 260.

The HD 6950 transistor size technology is 25 nm (nanometers) smaller than the GeForce GTX 260. This means that the HD 6950 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 260.

The GeForce GTX 260 requires 182 Watts to run but there is no entry for the HD 6950. We would recommend a PSU with at least 500 Watts for the HD 6950 and a PSU with at least 500 Watts for the GeForce GTX 260. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon HD 6950 XFX Dual-Fan 2GB Edition is a special edition of high-end Radeon HD 6950.
The only new feature is a new cooling system which is more effective in a way it dissipates heat better and produces less noise. No changes that affect performance directly, such as OCking were made. Therefore, its performance is on level with the reference Radeon HD 6950.
Overview
GeForce GTX 260 is a Performance Graphics Card based on the Second Revision of the Tesla Architecture.

Architecture
Tesla was NVIDIA's First Unified Shader Architecture.

GPU
It equips a GPU Codenamed G200-100-A2 which has 8 Stream Multiprocessors activated and thus offers 192 Shader Processing Units, 64 TMUs and 28 ROPs. The Central Unit is clocked at 576MHz.

Memory
The GPU accesses a 896MB frame buffer of GDDR3, through a 448-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 999MHz.

Features
DirectX 10.0 Support (10.0 Hardware Default) and support for SLI, NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 182W, it requires at least a 500W PSU and it requires at least two 6-pin available connectors.

Performance
Gaming benchmarks put its performance around of a Radeon HD 4870, meaning it is much faster than GeForce GTS 250.
