How can embedded devices possibly confirm two transactions with their limited CPU?

There's a few answers here: (1) the small devices can offload the proof of work to a more powerful "parent" device of some sort. (2) devices will get smaller, cheaper, and faster in the coming years, so this will become less of an issue (3) the IOTA Foundation is developing "trinary" type devices (Jinn) which are optimized for these kinds of computations.

Clarification: There is absolutely no problem for a tiny device to confirm transactions (they just have to check that the checksum is OK, which is very easy). The problem is that they have to to do proof-of-work to make their own transaction possible for others to confirm and for that they need to find a number that gives a hash that ends in a lot of 9s.

It is possible to move this PoW from the tiny device to one central computer according to this speech though:
"Talk by Harm van den Brink, Distributed Ledger (IOTA) expert at, the Tech Deep Dive at Delft University of Technology. "

I personally believe that it should be possible with some sort of proof-of-stake (in a part of the Tangle) instead of, or partly replacing, proof-of-work. Raiblocks with their blockchain-DAG-mix has something like this, and the already implemented Flash channels are getting rid of some of the proof-of-stake too.

Devices with limited CPU will be able to outsource POW to a local iota-node (Server with enough processing power).
