I can't really offer proof, but hardware RAID cards have processors on them (and usually cache RAM). They do offload the processing, and there is a performance difference. You also can't boot to a software RAID, because software to recognize it is within the OS. With a hardware RAID, the controller emulates a single, bootable drive.
