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 780.

The GeForce GTX 780 has a 63 MHz higher core clock speed than the HD 7950, but the HD 7950 has 144 more Texture Mapping Units than the GeForce GTX 780. As a result, the HD 7950 exhibits a 103.1 GTexel/s better Texture Fill Rate than the GeForce GTX 780. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GTX 780 has a 63 MHz higher core clock speed than the HD 7950, but the HD 7950 has 48 more Render Output Units than the GeForce GTX 780. As a result, the HD 7950 exhibits a 35.4 GPixel/s better Pixel Fill Rate than the GeForce GTX 780. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GTX 780 was released over a year more recently than the HD 7950, and so the GeForce 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 6144 MB more video memory than the GeForce 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 431.6 GB/sec greater memory bandwidth than the GeForce GTX 780, which means that the memory performance of the HD 7950 is massively better than the GeForce GTX 780.

The Radeon HD 7950 3-way Crossfire has 5376 Shader Processing Units and the GeForce GTX 780 has 2304. However, the actual shader performance of the HD 7950 is 3656 and the actual shader performance of the GeForce GTX 780 is 2078. The HD 7950 having 1578 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 GeForce GTX 780.

The Radeon HD 7950 3-way Crossfire requires 540 Watts to run and the GeForce GTX 780 requires 250 Watts. We would recommend a PSU with at least 600 Watts for the GeForce GTX 780, but we do not have a recommended PSU wattage for the HD 7950. The HD 7950 requires 290 Watts more than the GeForce GTX 780 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 GeForce GTX 780.

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 780 is a high-end graphics-card based on the 28nm, Kepler architecture.
It's based on the Kepler GK110 Core (same used on Titan) but with 12 SMX activated and therefore offers 2304 Shader Processing Units, 192 TMUs and 48 ROPs on a 384-bit memory interface of fast GDDR5. While the central unit runs at 863MHz and goes up to 902MHz in Turbo, the memory clock operates at 1502MHz. It consumes up to 250W.
Benchmarks indicate that its performance is up to 30% better than previous GeForce GTX 680 and thus allows even the most demanding games to be playable at the highest settings, at 1080p. With proper overclocking and cooling, it can surpass GeForce GTX Titan.
