While we are on this topic, what exactly does 32gb of ram get us? I assume it means the MBA has more ram to devote to graphics for say, some particularly demanding game? Any other potential use cases that might need that much memory?
The more RAM you have the more you will use. At the very, very, very least it will reduce the swap wear on SSD and continue with improved performance instead of swap between reboots.
I went with 16GB on my M1 MBA, which felt perfect. 24GB on my M4 MBA, but I run some LLMs.
For most people, 16GB is perfectly ample. That's a ton of extra room for Apple Intelligence, as the features roll out.
But 32GB would allow me to run larger LLMs. Or perhaps a better gaming experience. And certainly it would allow more Safari/Chrome tabs with less swap.
