If I understand correctly, the unified memory in Apple Silicon is shared and used both as "regular" RAM and also as "VRAM." Is this correct? And if so, would people want to actually consider upgrading to higher memory levels in Apple Silicon computers compared to what they're used to?
Because, for example, if you nearly reached the limits of 16GB RAM and had a 4 GB graphics card before on an Intel machine, and now that memory is being shared for other additional uses, would that mean you'd want more like a minimum of 20+ GB RAM (obviously 32 GB is the next step up, though) to get a similar ceiling, depending on what you're working with?
If anyone could help me understand/explain why this is or isn't true, that would be very helpful.
