In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 3-way Crossfire are significantly better than the Nvidia GeForce GTX 950 2GB SLI.

The GTX 950 has a 224 MHz higher core clock speed than the HD 7950, but the HD 7950 has 240 more Texture Mapping Units than the GTX 950. As a result, the HD 7950 exhibits a 170.5 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 224 MHz higher core clock speed than the HD 7950, but the HD 7950 has 32 more Render Output Units than the GTX 950. As a result, the HD 7950 exhibits a 11.3 GPixel/s better Pixel Fill Rate than the GTX 950. 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 three years more recently than the HD 7950, and so the GTX 950 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 7950 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 7950 has 5120 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 7950 also has superior memory performance overall.

The HD 7950 has 508.4 GB/sec greater memory bandwidth than the GTX 950, which means that the memory performance of the HD 7950 is massively better than the GTX 950.

The GeForce GTX 950 2GB SLI has 1536 Shader Processing Units and the Radeon HD 7950 3-way Crossfire has 5376. However, the actual shader performance of the GTX 950 is 2463 and the actual shader performance of the HD 7950 is 3656. The HD 7950 having 1193 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 950.

The GeForce GTX 950 2GB SLI requires 180 Watts to run and the Radeon HD 7950 3-way Crossfire requires 540 Watts. We would recommend a PSU with at least 450 Watts for the GTX 950. The HD 7950 requires 360 Watts more than the GTX 950 to run. The difference is significant enough that the HD 7950 may have an adverse affect on your yearly electricity bills in comparison to the GTX 950.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 950 2GB SLI is a solution of two GeForce GTX 950 2GB put together using NVIDIA's SLI technology.

Architecture
The Second variant of the Maxwell Architecture, despite being also manufactured with a 28nm technology, has an extremely large L2 Cache and features a Third Generation Delta Color Compression which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

GPU
It consists of 2 GPUs codenamed GM206-250 which, together, offer 1536 Shader Processing Units, 96 TMUs and 64 ROPs. The central unit runs at 1127MHz and goes up to 1178MHz, in Turbo Mode.

Memory
Each GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1653MHz.

Power Consumption
Power Consumption is around 180W.

Performance
Gaming benchmarks prove that at 1920x1080, the best suited resolution, GeForce GTX 950 2GB SLI is only around 5% slower than the older GeForce GTX 780, meaning a single GeForce GTX 970 is still considerably faster.

System Suggestions
We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Radeon HD 7950 3-way Crossfire is a solution of three Radeon HD 7950 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7950 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is somewhat superior to a single Radeon HD 7990 performing by itself it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 7950. Expect this combination to draw up to 540 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
