ASRock Rack SPC621D8 Server Motherboard vs Asus Z11PR-D16 Server Motherboard

Buy the ASRock Rack SPC621D8 for a new single-socket build on 3rd Gen Xeon Scalable: it has PCIe 4.0, 13 SATA ports and an ATX footprint that fits standard cases. Buy the ASUS Z11PR-D16 only if you already own or need two LGA 3647 Xeon Scalable CPUs and 16 DIMMs of memory capacity. The ASUS is the older platform: PCIe 3.0 only, two x16 slots, and an SSI EEB size that needs a large case. Both are bare server boards with IPMI management and no consumer features; neither has audio, video output for general use, or overclocking.

• Choose the ASRock Rack SPC621D8 if you are building around one 3rd Gen Xeon Scalable CPU and want PCIe 4.0, many SATA drives and a standard ATX case.
• Choose the ASUS Z11PR-D16 if you need two LGA 3647 processors and up to 16 DIMMs, and PCIe 3.0 plus two x16 slots is enough.
