Texture upload to an onboard GPU are faster, iirc.

Especially when it's already in right format in the same address space. Then upload is not needed at all.

Except that GPUs don't usually read from linear "raster order" images or are very slow doing so. So even in a shared memory CPU/GPU setup, there is a texture "upload" which organizes the pixel data to a GPU cache-friendly block format.
