Newb and noob may have somewhat different connotations. Newbs are simply newcomers—noob and n00b, on the other hand, generally means someone who is obnoxious, annoying, or breaks the rules; whether they are actual newcomers or not is mostly irrelevant. Therefore, a noob may be someone who has been around for a long time but still engages in behavior that he or she should have learned is unacceptable. Noobs are generally confident in what they are doing, but in reality are annoying others. "Newb" is not necessarily an insulting word, but "noob" usually is. If someone makes an unintelligent comment on a forum or asks a question that even other newbies could answer then it is said that they are making a "noobish" comment or asking a "noobish" question. However, due to the evolution of language, the term noob or 'n00b' is now used both ways and newb is used only infrequently. (from wikipedia)
He is a newb, not a n00b.
