Processors with DDR5 support

DDR5 is the socketed memory standard of desktops and laptops; over DDR4 it brings higher data rates and two sub-channels per module. In a laptop DDR5 usually means SO-DIMM slots, so the memory can be added to later; look at where the maker states the slot count and the maximum. For a processor or a motherboard DDR5 describes the supported type, not what is in the box.
