In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 Gainward Phantom GLH Edition are significantly better than the AMD Radeon Sky 700.

The GTX 780 was released less than a year after the Radeon Sky 700, 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 Sky 700 has 3072 MB more video memory than the GTX 780, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 780 has superior memory performance.

The GTX 780 has 24.4 GB/sec greater memory bandwidth than the Radeon Sky 700, which means that the memory performance of the GTX 780 is slightly better than the Radeon Sky 700.

The GeForce GTX 780 Gainward Phantom GLH Edition has 2304 Shader Processing Units and the Radeon Sky 700 has 1792. However, the actual shader performance of the GTX 780 is 2380 and the actual shader performance of the Radeon Sky 700 is 1048. The GTX 780 having 1332 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 780 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 GTX 780. We would recommend a PSU with at least 600 Watts for the GTX 780.

GPU Mini Review

Mini ReviewGeForce GTX 780 Gainward Phantom GLH Edition is a special edition of the high-end GeForce GTX 780.
This edition comes with a custom triple fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 863MHz to 980MHz while its boost clock is now of 1033MHz. The memory clock was also increased to 1550MHz.
Benchmarks indicate a 8% performance boost when compared to the reference card.
Radeon Sky 700 is a high-end GFX that's based on the 28nm, GCN architecture.
Its performance is comparable to a single Radeon HD 7950, due to the Core similarities but consumes more power (up to 225 Watt).
