What medium armor level are you? Do you have skill passives for more damage coming out of sneak? Or are you noticing this at level 1 out the gate? Is your weapon of an appropriate damage level?
I have almost all medium armor sneak bonuses from Medium and Khajit with weapons equal to my level attacking from behind and it isn't even worth bothering to go in to sneak for.
In beta I was using worse armor, no passives and much worse weapons and was doing at least four times the damage.
