Misses the other major benefit of SOC integrated memory. In a traditional system if I want to move an image from memory to a graphics card that image data has to be copied from the CPU's RAM to the RAM on the GPU, byte by byte. Similarly, if I want the GPU to perform some action on that image and return it then the result needs to be copied once more from the GPU back to the CPU.

More interested in the running Mac apps on the device part. Am I going to need a Vision Pro with 16GB of RAM and 1TB of SSD storage like the iPad Pro?

Probably this is common knowledge, but why has Apple made so much Not user upgradable? Is it to sell more new machines ? Is it to eliminate technical problems when users upgrade? Conceptually, I want more control of the thing I pay thousands for. 

One thing is that all of the RAM in onboard the SOC and shared between the CPU, GPU, and various other systems like the NE. THat's where a lot of the performance comes from in that memory is on the chip and it doesn't have to go to an external bus to get it. Further, moving something like a shader or bitmap from the CPU to the GPU is basically just passing a pointer, as opposed to copying a bunch of bytes back and forth.

Adding external RAM kills off aspect of the performance.

Didn't discuss screen quality. Do things look high definition? Any screen-door effects?

I don't need access to a gigantic database of previously written text in order to type or write. AI programs do. Turn off the database access and they're useless. 

As pointed out, they've been "trained" on a large corpus of information.

As have you, since birth.
