Apple exec doesn’t actually understand how computers work and think that that actually might be a reasonable arguement.
It doesn’t matter how good your processor is if you can only bank 8 GB of something into memory it’s going to be slow. The only way an 8 GB device would beat a 16 GB device would be if the 16 GB device had the world’s slowest processor. Like something from 2005. Taking stuff out of RAM is the single slowest operation you can perform other than loading from a hard drive.
