In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 Boost Edition Crossfire are significantly better than the AMD Radeon Sky 700.

The Radeon Sky 700 was released less than a year after the HD 7950, and so they are likely to have similar driver support for optimizing performance 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 Radeon HD 7950 Boost Edition Crossfire and the Radeon Sky 700 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7950 has 216 GB/sec greater memory bandwidth than the Radeon Sky 700, which means that the memory performance of the HD 7950 is massively better than the Radeon Sky 700.

The Radeon HD 7950 Boost Edition Crossfire has 3584 Shader Processing Units and the Radeon Sky 700 has 1792. However, the actual shader performance of the HD 7950 is 2818 and the actual shader performance of the Radeon Sky 700 is 1048. The HD 7950 having 1770 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 Radeon Sky 700.

The Radeon Sky 700 requires 225 Watts to run but there is no entry for the HD 7950.
