Can I use Apple Intelligence smoothly with 8GB RAM by quitting other applications?

Hello, I have an M3 MacBook Air with 8GB of RAM that runs MacOS Sequoia. After having queried about Apple Intelligence for a while, I’ve finally decided to enable it. There’s been a lot of talk about how 8GB of RAM isn’t enough these days. Would I be able to use Apple Intelligence smoothly enough if I quit all other applications while using it? Also, in general, if I’m not running too many applications simultaneously, does less RAM negatively affect power consumption/battery life? I’d be grateful if anyone could advise me on these things, please.
