No, the difference is in whether your vocal cords are vibrating. when 
you're whispering, the difference is that the "unvoiced" [both are 
actually unvoiced] one uses more air (in "th"'s case, the tongue may be 
slightly further forward to let more air through - I'll take a guess and 
say you probably arrived at a conclusion by repeating the two sounds and 
analyzing where your mouth was, but did it at a whisper to avoid 
sounding like an idiot to those around you). this is true for all such 
consonant pairs [p/b, t/d, s/z, k/g]
