What do you guys do with this information? (genuine question, im curious)

See how far a certain cpu bin can undervolt up to. For example from the three replies mine has the lowest voltage per clock speed (clock speed is the left column, voltage on the right). Undervolting *may* have some benefits but is generally not recommend.

It MAY decease battery usage by a very minuscule amount
It has a better chance of reducing heat coming from the cpu when running at higher frequencies.
It has a lot of drawbacks if you're not careful
(random reboots, lock ups, artifecting, etc to name a few)

That's informative. Thanks!

and worst of all sleep of death and device rebooting as soon as boots up.
