Intel Xeon Gold 6421N 32 Cores 64 Threads 3.6GHz E (LGA 4677) PK8071305122001 Server CPU

Data Centre Server Processor Optimised for I/O-Dense Compute with Intel Xeon Gold 6421N (PK8071305122001)

The Intel Xeon Gold 6421N is a 4th Gen Intel Xeon Scalable “Sapphire Rapids” CPU for LGA4677 single-socket platforms, designed for consolidated enterprise compute where core density, predictable throughput, and platform bandwidth must scale together. With 32 cores and 64 threads, it aligns well with virtualization clusters, private cloud nodes, and mixed workloads that require balanced per-core performance and consistent scheduling under contention.

Intel Xeon Gold 6421N enables modern memory and I/O topologies by pairing DDR5 platform capabilities with up to 80 PCIe 5.0 lanes (platform-dependent) for high-lane-count expansion. This supports I/O-dense architectures such as NVMe-heavy storage tiers, high-speed networking, and accelerator attachment without oversubscription, helping reduce bottlenecks in east-west traffic and storage-intensive databases. For secure multi-tenant operation, Intel VT-x and VT-d improve isolation and device assignment, while instruction support including AES-NI and Intel DL Boost helps optimize encryption and AI-assisted analytics in standard enterprise pipelines.

Why Choose the Intel Xeon Gold 6421N?

The Intel Xeon Gold 6421N provides a pragmatic density-to-performance ratio for single-socket servers where PCIe Gen5 expansion and memory bandwidth are strategic constraints. It supports scalable deployment patterns for standardized node builds, simplifies capacity planning with a 185 W TDP envelope, and strengthens reliability for always-on services through hardware-backed security features suited to regulated environments.

Intel engineers the Xeon Scalable platform to meet data centre operational requirements, emphasizing validated server ecosystem compatibility, long lifecycle support, and robust security foundations. With Intel Xeon Gold 6421N, architects can standardize on a contemporary Sapphire Rapids CPU that aligns with current rack, power, and management standards.
