Intel Xeon Gold 6421N 32-core server processor
The Intel Xeon Gold 6421N is a 32-core, 64-thread server CPU built on 10 nm Sapphire Rapids architecture. It operates at a 1.8 GHz base frequency with a 3.6 GHz maximum turbo frequency and provides 60 MB of L3 cache. This processor targets single-socket servers handling virtualisation, database and compute-intensive workloads.
DDR5 4800 eight-channel memory
The integrated memory controller supports DDR5 4800 across eight channels with a maximum capacity of 4 TB. PCI Express 5.0 delivers up to 80 lanes for high-speed storage and networking expansion. Single-socket scalability means this CPU cannot be paired with a second processor in a dual-socket configuration.
LGA 4677 socket and 185 W thermal design
The processor fits the LGA 4677 socket and carries a 185 W thermal design power; a cooling solution is not included and must be sourced separately. Intel AMX, AVX-512, AVX2, AVX and SSE4.2 instruction sets accelerate AI inference and vector workloads. The 1S-only design limits deployment to single-processor motherboards.

この商品に関する質問
Should I choose the 32-core 1.8 GHz version or a higher-frequency model with fewer cores?
This model delivers 32 cores and 64 threads at 1.8 GHz base with a 3.6 GHz max turbo, giving high multi-thread throughput for virtualisation or database workloads.
What does the 3.6 GHz max turbo frequency mean once the chip is installed in a server?
The processor can lift up to 3.6 GHz on active cores when thermal headroom allows, boosting single-thread performance while the 185 W TDP sets the sustained power envelope.
How does the PCI Express 5.0 interface with 80 lanes affect expansion capacity?
PCIe 5.0 provides up to 80 lanes, allowing multiple high-bandwidth devices such as GPUs or storage arrays without lane contention.
