In terms of overall gaming performance, the graphical capabilities of the AMD Radeon Sky 500 are significantly better than the Nvidia GeForce GTX 650 Gigabyte OC 1GB Edition.

The Radeon Sky 500 was released less than a year after the GTX 650, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon Sky 500 has 3072 MB more video memory than the GTX 650, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon Sky 500 also has superior memory performance overall.

The Radeon Sky 500 has 73.6 GB/sec greater memory bandwidth than the GTX 650, which means that the memory performance of the Radeon Sky 500 is much better than the GTX 650.

The Radeon Sky 500 has 1280 Shader Processing Units and the GeForce GTX 650 Gigabyte OC 1GB Edition has 384. However, the actual shader performance of the Radeon Sky 500 is 790 and the actual shader performance of the GTX 650 is 426. The Radeon Sky 500 having 364 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon Sky 500 delivers a significantly smoother and more efficient experience when processing graphical data than the GTX 650.

The Radeon Sky 500 requires 150 Watts to run but there is no entry for the GeForce GTX 650 Gigabyte OC 1GB Edition. We would recommend a PSU with at least 400 Watts for the GTX 650, but we do not have a recommended PSU wattage for the Radeon Sky 500.

GPU Mini Review

Mini ReviewRadeon Sky 500 is a high-end GFX that's based on the 28nm, GCN architecture.
Its performance is comparable to a single Radeon HD 7870, due to the Core similarities but consumes less power (up to 150 Watt).
GeForce GTX 650 Gigabyte OC 1GB Edition is a special edition of the fast-middle-class GeForce GTX 650 1GB.
This special edition comes overclocked out of the box to 1110MHz and features a custom-designed 10 cm cooler.
Benchmarks indicate a 4% performance boost when compared to the reference card and so this GPU is suitable for medium to high settings on most demanding games but not with extreme resolutions.
