Yeah, if you want more RAM (since 8GB really ain't too much nowadays, especially since it's shared with the GPU) ~~you gotta buy the Pro version for over double the price.~~

Edit: According to replies you can upgrade to 16 GB for $200. I guess that's not too bad for Apple standards. Apple Silicon or not, 16GB still should be the default.

8GB of RAM on apple silicon is more than enough. You’re comparing apples to oranges (literally) macOS is far far more efficient than windows and basically has no overhead.

I used an m1 Mac Pro as my work daily driver (IT engineer at a small MSP) and I never ever saw any real slow downs with only 8GB of RAM. Unless I was using an app poorly optimised for ARM.

Granted in a couple years this might be a different story…
