According to the Wizards Optimisation forums for 4e:
"What I've observed is: 14 DPR(1st), 20 DPR(6th), 40 DPR(12th), 60 DPR(16th), 100 DPR (24th), 150 DPR(30th)"
DPR meaning damage per round.
If you're going to go "that's not possible", one of many character builds that accomplish it is here, and it's not even a particularly munched out or complex one to do. There are also builds that do more damage.
Even at first level, though, you can expect to take out a guy every two rounds with a decently-made striker, and damage increases ten-fold from there to level 30.
Actually, my understanding was that CO considered 20 DPR per tier to be a reasonably good figure, with things like 60 DPR at 16 being more in the DPR records.
