Does the i7 drain the battery faster than i5

[polly1]

the Toshiba Portege R700 hasa choice of processors: i7 dual core 620M vs i5 520M...will there be a noticeable batery drain if I go with i7?
The price differential is immaterial.
Thanks!

No,both will give you pretty much the same amount of battery life.(However,in turbo mode 620M drains faster)
