INTEL Xeon 6438M 2.20GHz CPU
The Intel Xeon Gold 6438M is a 28-core, 56-thread processor from the 4th Gen Intel Xeon Scalable family (Sapphire Rapids microarchitecture), aimed at virtualization hosts, compute clusters, and storage/controller workloads that need high memory bandwidth and I/O throughput. Note that the FCLGA4677 socket means it is only compatible with supported C741/W790-class server and workstation platforms, so verify board compatibility before ordering. DDR5 support with eight memory channels makes it well suited to memory-hungry workloads such as databases and in-memory analytics.

Good to know
- Compatibility: requires an FCLGA4677 motherboard; it is not drop-in compatible with 3rd Gen Ice Lake-SP (LGA4189) systems, so plan platform-level upgrades accordingly.
- Positioning: within the Sapphire Rapids family, the “M” suffix denotes a high-core-count Gold SKU with a 205W TDP, sitting above the lower-TDP Gold X variants and below the Platinum tier, balancing core density and power draw.
- Buying tip: confirm your chassis and VRM can sustain the 205W TDP and that DDR5 RDIMMs (not DDR4) are specified for your platform — mixed procurement of memory types is a common source of RMA claims in Huaqiangbei batch orders.
