However, I have to report that my overall day-to-day experience with my 16GB M1 Mac mini has been quite good. I won't jump into the online melee over whether the 16GB maximum memory is a real disadvantage from a performance standpoint, given that most Intel-based PCs routinely have 32GB, 64GB or even higher amounts of memory. This approach's upside is higher performance the downside is you must choose what level of memory you desire at time of purchase, and there is no post-sale upgrade opportunity. From a practical standpoint, the crucial difference is that in the M1, memory is an explicit element of the architecture, so there are no memory slots on the system board for a M1 Mac. Unlike Intel processors’ integrated graphics, the M1 has an embedded graphics processor shared between both the processor cores and graphics cores.
