Having looked at again I would actually say the one of the left like the rest, the only reason I said the one on the right initially is because it had a M product code and that might mean Motorola as the CPU is Motorola as well, now I think of it I seem to remember the standard chips were Intel, also that sticker on the left looks more genuine than the one on the right.

You can only swap chips on a like to like basis I.E a L6 chip for an L6 but you can't use the L6 (Saph) chip in a L1 (3DR) ECU as the electronics are completely different.
