On a fresh reboot and login to a KDE desktop, the total memory use (minus disk cache) on my system is just a hair over 1GB. This is on a ~10 year old Phenom II with 16GB RAM, and KDE is smooth as butter. It runs great on my Thinkpad X220i, too.
Firefox or Chrome will absolutely dwarf your DE in memory usage, so I don't think it's really a major differentiator between KDE and Gnome. If your PC has less than 2GB of memory, you'll run into other issues first.
