ASRock Rack SPC621D8 Server Motherboard vs SuperMicro X14SBI-F Server Motherboard

Buy the ASRock Rack SPC621D8 if you already own or plan to buy a 3rd Gen Xeon Scalable CPU and need lots of PCIe 4.0 lanes and SATA drives. Buy the SuperMicro X14SBI-F if you are building on a newer Xeon platform with DDR5 memory and want SuperMicro's server track record. The ASRock gives more slots and ports on paper; the SuperMicro gives a newer memory standard and a brand with deep server support. Neither is a desktop board, and both expect server parts and a server case.

• Choose the ASRock Rack SPC621D8 if you have a 3rd Gen Xeon Scalable chip and need four x16 slots, seven PCIe 4.0 slots total and 13 SATA ports.
• Choose the SuperMicro X14SBI-F if you are starting fresh on a current Xeon platform and want DDR5 memory and SuperMicro's server support.
