If a program allocates 1GB with malloc(), then 1GB of space is required to make a reservation for that program to run. That reservation can be backed by RAM or by swap files. If you have an 8GB VM, some amount of that memory will go to various overheads in the kernel and system software. If you run programs that end up allocating more than is left over, you'll need swap to back those allocations.
