Image format for fast texture upload


I would like to know if there is any specific image format, on windows and linux, that is faster than the others to upload texture data. For example on macos using GL_BGRA with GL_UNSIGNED_INT_8_8_8_8_REV, you get maximum performance (no byte swaps etc.).

Thanks for your answers,


Meanwhile I found this . Can I expect the same kind of behaviour on ati cards ?
