That’s a complicated question. Bigger memory can split it between more banks, which can mean more precharge penalties if the memory you need to access is spread out between them.

But big memory systems generally use workstation or server processors, which means more memory channels, which means the system can access multiple regions of memory simultaneously. Mini-PCs and laptops generally only have one memory controller, higher end laptops and desktops usually have two, workstations often have 4, and big servers can have 8+. That’s huge for parallel workflows and virtualization.
