When to choose the Gold 6421N
In Intel’s line-up this processor sits in a mainstream server tier that balances core count, frequency and power. With 32 cores on the FCLGA4677 platform it suits dense virtualisation, databases and high-throughput compute, and its 185 W TDP sets the cooling and power budget for the node.
Platform & compatibility
The Intel Xeon Gold 6421N uses the FCLGA4677 socket on 1S Only platforms, supports Up to DDR5 4400 MT/s 1DPC and 2DPC, with up to 8 memory channels, and up to 4 TB of memory, provides PCI Express 5 (80 lanes). Confirm the exact OEM platform, BIOS level and memory population for your workload before ordering.
Deployment notes
The Gold 6421N installs in a FCLGA4677 platform with up to 8 memory channels and up to 4 TB of memory. Intel SGX provides application enclaves. It is launched as part of 4th Gen Intel® Xeon® Scalable Processors and is intended for dense virtualisation, databases and high-throughput compute.
