8GB is not enough for running applications like that. I think we all should know that by now. If you're doing FC, Blender, C4D or Adobe anything, you get as much RAM as you can afford. So no one is really going to buy an 8GB model for that. It's kind of miss-leading to even make a performance comparison using it. Other than to clearly state the obvious. Don't buy lowest end Mac pro for this kind of work. If you're not doing that kind of work. 8GB is fine for most basic tasks. Which is why it is an option. If you're in school, and need/want a Mac Book. This is clearly aimed at that group. Writers, or content consumption. NOT for creation, and heavy multitasking.
Apple stating that 8GB is like Windows with 16. Is factoring in features that exist on the Mac that can alleviate some of the memory limitations. But, it's always better to have real RAM available to the system over SSD swapping.
So another note to self. Don't buy the least powerful Mac and expect it to work miracles.
Know what type of work you're going to be doing with it, and purchase accordingly. All of my Mac's (ALL OF THEM) in the past 10 years have had 32GB or MORE of RAM. They don't need the highest end CPU (iMac Pro is an 8 Core with 32GB of RAM. nMac Pro has 64GB of RAM as it was upgradable). All of my MacBook Pro's have 32GB of ram. Even this M2 Max has 32. My M1 Max Studio has 32GB, and so on. I have not experienced any memory issues or speed issues or any issues (except heat on those intel mac's).
Should Apple sell ONLY 16GB as a base? You can argue that. But, having 8 as an option lowers the price of entry for those that really don't need more. And if it was taken away, others would complain that it's too expensive.
And others will complain that Apple should just eat the cost increase. And as a Shareholder I say NO to that.
