52-Core Xeon for Two-Socket Servers

The Intel Xeon Platinum 8470 is a 52-core server processor built for dual-socket platforms. It targets data-centre workloads that scale across 104 threads, such as virtualisation, database and high-performance computing tasks. The LGA 4677 package fits compatible server motherboards designed for the Sapphire Rapids architecture.

DDR5 Memory Limits at Scale

The integrated controller runs DDR5 at 4800 MT/s with one DIMM per channel and drops to 4400 MT/s when both slots are populated. Eight memory channels support up to 4 TB of total capacity, so maximum bandwidth requires a full complement of single-rank modules. Filling every channel with two DIMMs per channel reduces the per-channel data rate.

PCIe 5.0 Lanes and Thermal Headroom

Eighty PCI Express 5.0 lanes provide connectivity for high-speed storage, networking and accelerator cards in a two-socket configuration. The processor carries a 350 W thermal design power and ships without a cooler, so the platform must supply adequate airflow and a compatible heatsink. Sustained all-core turbo at 3.80 GHz will demand the full cooling budget.

Questions sur cet article

Should I choose the 52-core 8470 or a lower-core model for my workload?

The 8470 delivers 52 cores and 104 threads at a 2.0 GHz base frequency, scaling to 3.80 GHz max turbo, suited for heavily parallel server tasks.

What does the 3.80 GHz max turbo frequency mean once the processor is installed in a server?

Under thermal and power headroom, up to 3.80 GHz can be reached on active cores; sustained all-core speeds will settle lower depending on the 350 W TDP and system cooling.

How does the LGA 4677 socket and PCIe 5.0 with 80 lanes affect expansion and memory limits?

LGA 4677 supports 8-channel DDR5 up to 4800 MT/s (1DPC) or 4400 MT/s (2DPC) with a 4 TB maximum, while PCIe 5.0 provides 80 lanes for high-bandwidth add-in cards.
