There are myths spread around that UMA has different memory consumption. That’s wrong. The way it moves data around is different from the x86 architecture (which has various interconnects to memory and GPUs) but the amount of memory the operating system, apps and documents/files consumes doesn’t change.
That may or may not be true, but it isn't the only thing that determines how much RAM you need. Whether you suffer a significant hit from less RAM depends also on speed of RAM utilization, speed of swapping, etc. In many cases, swapping isn't even noticeable.
It will always be preferable to use real RAM than swapping to disk. The latter will age your drive faster.
Is there some evidence drive aging is a serious problem in this context? I've seen that point raised a lot, but haven't seen any data in its favor. The data cited so far seems to suggest otherwise.
If you’re a creative or developer you should get more RAM every time.
Anyone who says 8GB is enough for creatives is cuckoo and they should go back to 2010 ??
That's way too broad. Many working with photos aren't working in medium format. Many working in video or audio aren't using using files that huge either. And many others are just doing graphics and such that may be even less demanding.
Use cases are individual. Really varies a lot depending on the details of what one is doing.
I see some content creation pros here saying they're doing fine with 8GB, and some saying they aren't.
