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 480 SLI.

The HD 7950 has a 99 MHz higher core clock speed and 216 more Texture Mapping Units than the GTX 480. This results in the HD 7950 providing 184.7 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 HD 7950 has a 99 MHz higher core clock speed than the GTX 480 and the same number of Render Output Units. This results in the HD 7950 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 7950 was released over a year more recently than the GTX 480, and so the HD 7950 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 480.

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 6144 MB more video memory than the GTX 480, 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 365.2 GB/sec greater memory bandwidth than the GTX 480, which means that the memory performance of the HD 7950 is massively better than the GTX 480.

The Radeon HD 7950 3-way Crossfire has 5376 Shader Processing Units and the GeForce GTX 480 SLI has 960. However, the actual shader performance of the HD 7950 is 3656 and the actual shader performance of the GTX 480 is 1346. The HD 7950 having 2310 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 480.

The HD 7950 transistor size technology is 12 nm (nanometers) smaller than the GTX 480. This means that the HD 7950 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 480.

The Radeon HD 7950 3-way Crossfire requires 540 Watts to run and the GeForce GTX 480 SLI requires 500 Watts. We would recommend a PSU with at least 750 Watts for the GTX 480, but we do not have a recommended PSU wattage for the HD 7950. The HD 7950 requires 40 Watts more than the GTX 480 to run. The difference is significant enough that the HD 7950 may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 480.

GPU Mini Review

Mini ReviewRadeon 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.
GeForce GTX 480 SLI is a solution of two GeForce GTX 480 put together using NVIDIA'S SLI technology.
SLI relies a lot on proper driver support and may cause micro stuttering in FPS below 30. This means this combination might even perform worse than a single GTX 480.
The optimal performance it delivers is largely better than a single GeForce GTX 480 and relatively close to GeForce GTX 590.
Therefore, this combination is sufficient for gaming at 1080p and most demanding games can be played at the highest settings.
