I am telling you. The differences in real time between tasks that overload 16 GB RAM that would be better served with 32 GB RAM is still so fast for the 16GB of RAM that it doesn't matter anyway. Who cares if compiling something takes an extra few minutes when you do it twice a year? And most of the time it is even faster than that.
Now if you are a professional video editor who messes with terabytes of 8k video all day long, then get what you need, and it will be more than 16GB or even 32GB.
Now realize that like less than 1 percent of us actually qualify for this.
I have found my BASE M4 Mac Mini 16GB/512GB is the same as my RTX 4060 i7-13700HK 32GB RAM machine for everything I do and more--with the exception of gaming. This M4 is so fast. Ridiculously fast. Given the Apple upgrade prices, I don't regret tossing like $699 at this thing. I could upgrade in like 3 years and still be ridiculously happy with the price I paid for the performance.
But don't just take my word for it.
There are more.
Thanks for the intention in sharing the videos and there certainly are loads of videos on the M4 - but many of them aren’t very helpful on this point. That Mark Ellis video is a load of waffling, for instance.
Really his only point on the specific specs and upgrades is that you should get the base M4 chip and then upgrade the SSD and RAM “if you need it”, or something like that.
