No, many garbage collection approaches WILL require more RAM, some need twice as much RAM to run efficiently. Then there is the case that with garbage collection can have a delay which lets garbage pile up thus using more memory than necessary. Retain-release used by Apple is not as efficient, but you reclaim memory faster. https://www.quora.com/Why-does-Garbage-Collection-take-a-lot-of-RAM https://www.quora.com/Why-does-Garbage-Collection-take-a-lot...
