“More” does not always mean “better”: higher power draw or size is a system requirement, not an advantage (such bars are dimmed).
Platform compatibility
Socket and BIOS support Needs checking
Both models use AM4, but support on a specific motherboard depends on the chipset and BIOS version. Check the board maker’s CPU support list.
Memory Needs checking
Both controllers support DDR4. The motherboard determines the memory type, so check its specification.
