In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 Ti Gigabyte OC 1GB Edition are massively better than the AMD Radeon HD 5670 512MB.

The GTX 560 Ti has a 125 MHz higher core clock speed and 44 more Texture Mapping Units than the HD 5670. This results in the GTX 560 Ti providing 42.1 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 GTX 560 Ti has a 125 MHz higher core clock speed and 24 more Render Output Units than the HD 5670. This results in the GTX 560 Ti providing 22.6 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 GTX 560 Ti was released less than a year after the HD 5670, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 560 Ti has 512 MB more video memory than the HD 5670, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 560 Ti also has superior memory performance overall.

The GTX 560 Ti has 64 GB/sec greater memory bandwidth than the HD 5670, which means that the memory performance of the GTX 560 Ti is much better than the HD 5670.

The GeForce GTX 560 Ti Gigabyte OC 1GB Edition has 384 Shader Processing Units and the Radeon HD 5670 512MB has 400. However, the actual shader performance of the GTX 560 Ti is 691 and the actual shader performance of the HD 5670 is 202. The GTX 560 Ti having 489 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 560 Ti delivers a massively smoother and more efficient experience when processing graphical data than the HD 5670.

The Radeon HD 5670 512MB requires 61 Watts to run but there is no entry for the GTX 560 Ti. We would recommend a PSU with at least 400 Watts for the HD 5670, but we do not have a recommended PSU wattage for the GTX 560 Ti.
