In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770 are massively better than the AMD Radeon HD 5850 Sapphire Vapor-X 1GB Edition.

The GeForce GTX 770 has a 311 MHz higher core clock speed and 56 more Texture Mapping Units than the HD 5850. This results in the GeForce GTX 770 providing 81 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 GeForce GTX 770 has a 311 MHz higher core clock speed than the HD 5850 and the same number of Render Output Units. This results in the GeForce GTX 770 providing 10 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 GeForce GTX 770 was released over three years more recently than the HD 5850, and so the GeForce GTX 770 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 5850 when running the latest games.

The GeForce GTX 770 has 1024 MB more video memory than the HD 5850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 770 also has superior memory performance overall.

The GeForce GTX 770 has 89.9 GB/sec greater memory bandwidth than the HD 5850, which means that the memory performance of the GeForce GTX 770 is much better than the HD 5850.

The Radeon HD 5850 Sapphire Vapor-X 1GB Edition has 1440 Shader Processing Units and the GeForce GTX 770 has 1536. However, the actual shader performance of the HD 5850 is 529 and the actual shader performance of the GeForce GTX 770 is 1667. The GeForce GTX 770 having 1138 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 770 delivers a massively smoother and more efficient experience when processing graphical data than the HD 5850.

The GeForce GTX 770 transistor size technology is 12 nm (nanometers) smaller than the HD 5850. This means that the GeForce GTX 770 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5850.

The GeForce GTX 770 requires 230 Watts to run but there is no entry for the HD 5850. We would recommend a PSU with at least 600 Watts for the HD 5850 and a PSU with at least 550 Watts for the GeForce GTX 770. The HD 5850 has been recommended a PSU with 50 Watts more than the GeForce GTX 770. The difference is significant enough that the HD 5850 may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GTX 770.

GPU Mini Review

Mini ReviewRadeon HD 5850 Sapphire Vapor-X 1GB Edition is a special edition of the high-end Radeon HD 5850.
This edition comes overclocked out of the box in both central unit and operating memory clock which were raised to 735MHz and 1050MHz, respectively.
Unfortunately, benchmarks indicate there is little to no performance boost when compared to the reference card.
