In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 SLI are very slightly better than the AMD Radeon HD 7950 3-way Crossfire.

The GTX 780 has a 63 MHz higher core clock speed and 48 more Texture Mapping Units than the HD 7950. This results in the GTX 780 providing 62.6 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 780 has a 63 MHz higher core clock speed than the HD 7950 and the same number of Render Output Units. This results in the GTX 780 providing 6 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 780 was released over a year more recently than the HD 7950, and so the GTX 780 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7950.

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 3072 MB more video memory than the GTX 780, 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 143.2 GB/sec greater memory bandwidth than the GTX 780, which means that the memory performance of the HD 7950 is massively better than the GTX 780.

The GeForce GTX 780 SLI has 4608 Shader Processing Units and the Radeon HD 7950 3-way Crossfire has 5376. However, the actual shader performance of the GTX 780 is 4156 and the actual shader performance of the HD 7950 is 3656. The GTX 780 having 500 better shader performance is not particularly notable, as altogether the HD 7950 performs better when taking into account other relevant data.

The GeForce GTX 780 SLI requires 500 Watts to run and the Radeon HD 7950 3-way Crossfire requires 540 Watts. We would recommend a PSU with at least 750 Watts for the GTX 780. The HD 7950 requires 40 Watts more than the GTX 780 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 780.

GPU Mini Review

Mini ReviewGeForce GTX 780 SLI is a combination of 2 GeForce GTX 780 put together using NVIDIA's SLI technology.
Together, this combination offers 4608 Shader Processing Units, 384 TMUs and 96 ROPs. This, on a 384-bit memory interface, per card, of fast GDDR5. While the central unit runs at 863MHz and goes up to 902MHz, in Turbo Mode, the memory clock operates at 1502MHz.
Best case scenario, this combination surpasses considerably a single GeForce GTX 690 but ultimately, its performance depends on the driver support and on the 3D application.
Therefore, and paired with a powerful processor, all demanding games are playable at the highest settings. Still, this combination might surpass the 500W barrier of TDP and so it will require a powerful PSU.
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.
