Model Number Difference

[Acctg_01]

Looking to buy a Note 3. Does anyone out there know what the difference is between Model Number SM-N9005 and SM-N900V for a Verizon phone? Have caught on E-Bay both being advertised as a Verizon phone. I have, so far, found that apparently the N9005 is unlocked and can be used with any GSM carrier, even though it is a CDMA phone. Not sure how this works though. Also saw something regarding a difference in clock speed between the two. Not sure what that means either. Can anyone shed some light?
