In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 Ti Inno3D OC Edition are marginally better than the Nvidia GeForce GTX 560 Ti Gigabyte OC 1GB Edition.

The GTX 560 Ti has a 20 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 560 Ti. This results in the GTX 560 Ti providing 1.3 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 20 MHz higher core clock speed than the GTX 560 Ti and the same number of Render Output Units. This results in the GTX 560 Ti providing 0.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the GeForce GTX 560 Ti Gigabyte OC 1GB Edition and the GeForce GTX 560 Ti Inno3D OC Edition were released at the same time, so are likely to be quite similar.

The GeForce GTX 560 Ti Gigabyte OC 1GB Edition and the GeForce GTX 560 Ti Inno3D OC Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 560 Ti has 3.2 GB/sec greater memory bandwidth than the GTX 560 Ti, which means that the memory performance of the GTX 560 Ti is marginally better than the GTX 560 Ti.

Both the GeForce GTX 560 Ti Gigabyte OC 1GB Edition and the GeForce GTX 560 Ti Inno3D OC Edition have 384 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the GTX 560 Ti has 1.3 GTexel/s better Texture Fill Rate and 0.6 GPixel/s better Pixel Fill Rate, but the GTX 560 Ti has 3.2 GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the GTX 560 Ti takes the edge.
