i3 models confusing

[cmentvaliantino]

i know this wouldn't be the best place to paste this but i hope you can help. I want to buy a new laptop with i3 but i learnt some have ultra low voltage 330um(1.2ghz) which gives low clock speed instead of 330M and others which give better clock speed(over 2ghz). Is the low voltage ones for mobiles only?

Look at this link. Apparently, the 330 UM and the 330 M are both mobile.

They differ in clock speed, maximum TDP, acceptable memory, and graphics.
