There isn't a single processor

Expeed refers to the image processing. Other processors handle AF functions.

That said, different focal lengths, different lenses, amount of available light, different focus distances, etc will all affect focus speeds. Do you think a casual user could really "test" a difference. Come on. I can't imagine any casual user (or even average pro) that good, that scientific, or has the equipment to do the exotic timing necessary!

Yes, it is a huge and complex topic. I've already made some fascinating discoveries, taking an engineering approach to investigate the details. I'll be starting a thread soon, to disclose those, so keep an eye out for it.
Hint: Lots of surprises in store for everyone!
