Product Overview

The Intel Xeon Platinum 8558P is a flagship 4th Generation Intel Xeon Scalable Processor (codenamed Sapphire Rapids) engineered for the most demanding enterprise and hyperscale computing environments. Built on Intel's advanced 10nm Enhanced SuperFin process technology, the 8558P delivers 48 physical cores and 96 threads operating at a base frequency of 2.10GHz with Turbo Boost capability, all within a 260W Thermal Design Power (TDP) envelope. Designed for the LGA4677 socket and compatible with Intel's 4th Gen Xeon Scalable platform (code-named Eagle Stream), this processor represents a significant leap in per-socket compute density, memory bandwidth, and I/O connectivity compared to its predecessors.

The 8558P is purpose-built for organisations that cannot compromise on compute throughput — whether running large-scale virtual machine farms, in-memory analytics, real-time AI inference, or mission-critical enterprise applications. Its inclusion of Intel Advanced Matrix Extensions (AMX) makes it uniquely suited for AI and deep learning inference directly on CPU, reducing dependence on dedicated accelerators for many workloads. The New Pulled condition designation indicates the unit has been removed from a factory-new or unopened system, ensuring full component integrity with no field wear.

Key Features & Benefits

• 48 Cores / 96 Threads: Exceptional multi-threaded throughput ideal for virtualisation hosts, containerised microservices, and parallel HPC tasks across a single socket.
• Intel Advanced Matrix Extensions (AMX): Dedicated matrix multiplication accelerator tiles built directly into the die dramatically accelerate AI/ML training and inference workloads without requiring a discrete GPU for many inference scenarios.
• 150MB L3 Cache (LLC): Massive last-level cache reduces memory latency for data-intensive applications such as in-memory databases, real-time analytics, and large working-set workloads.
• DDR5-4800 Memory Support with 8-Channel Controller: Eight independent DDR5 memory channels per socket deliver over 300 GB/s of peak memory bandwidth, essential for memory-bound AI, scientific simulation, and analytics workloads.
• PCIe 5.0 and CXL 1.1 Support: Up to 80 lanes of PCIe 5.0 per socket provide double the bandwidth of PCIe 4.0, enabling ultra-fast NVMe storage arrays, high-speed networking, and Compute Express Link (CXL) memory expansion.
• Intel Speed Select Technology (SST): Granular per-core frequency and power management allows administrators to prioritise latency-sensitive workloads while maximising overall utilisation.
• Built-in Security Enhancements: Intel Total Memory Encryption — Multi-Key (TME-MK), Trust Domain Extensions (TDX), and Software Guard Extensions (SGX) provide hardware-level confidential computing for regulated industries and cloud tenants.
• HBM2e High Bandwidth Memory (Platform Option): When paired with HBM-equipped variants at the platform level, memory-bound workloads achieve unprecedented bandwidth, though the 8558P itself leverages standard DDR5 with optional CXL expansion.

Technical Architecture

The Intel Xeon Platinum 8558P is based on the Sapphire Rapids micro-architecture, which introduced a tile-based die design for Intel's server lineup. The processor is constructed from multiple compute tiles (each containing CPU cores, LLC slices, and mesh interconnect logic) bonded together using Intel's Embedded Multi-die Interconnect Bridge (EMIB) packaging technology. This approach allows Intel to achieve the equivalent of a monolithic large die while maintaining manufacturing yield advantages.

Each core implements the Golden Cove micro-architecture, featuring a wider out-of-order execution engine, improved branch predictors, and an enhanced vector execution pipeline with support for AVX-512 (including VNNI, BF16, and FP16 instruction sets). The AMX unit comprises two 2D register tiles (TMUL tiles) capable of performing INT8 and BF16 matrix operations, providing a quantum leap in AI throughput versus prior-generation AVX-512 VNNI acceleration.

The on-die mesh interconnect connects all cores, LLC slices, memory controllers, and I/O interfaces with a coherent, low-latency fabric. The LGA4677 socket supports both single-socket (1S) and dual-socket (2S) configurations via Intel Ultra Path Interconnect (UPI) 2.0 links, offering up to 24 GT/s per UPI link for inter-socket coherency traffic in 2P server builds.

Performance & Capacity

In industry-standard benchmarks, the Xeon Platinum 8558P consistently delivers top-tier performance across diverse workload profiles. In SPECrate2017_int_base (multi-copy integer throughput), a dual-socket 8558P configuration posts scores competitive with the fastest x86 server platforms available at launch. For floating-point intensive scientific workloads (SPECrate2017_fp_base), the wide AVX-512 pipelines and 150MB of LLC contribute to outstanding throughput per node.

Memory subsystem performance is a particular highlight: eight DDR5-4800 channels per socket yield a theoretical aggregate bandwidth exceeding 307 GB/s per socket, making a 2S platform capable of over 600 GB/s system-wide — critical for bandwidth-hungry applications including genomics, financial risk modelling, and large language model (LLM) inference. PCIe 5.0 connectivity delivers up to 128 GB/s of raw I/O bandwidth per socket, fully utilising modern NVMe-oF arrays and 400GbE network adapters. For AI inference, AMX BF16 throughput enables the 8558P to process transformer-based model inference at rates previously achievable only with dedicated accelerators for smaller model sizes.

Compatibility & Integration

The Intel Xeon Platinum 8558P is compatible with all platforms designed for 4th Generation Intel Xeon Scalable Processors using the LGA4677 (Socket E) interface. Major server OEM platforms include HPE ProLiant DL380 Gen10 Plus / DL560 Gen11, Dell PowerEdge R750 / R760 / R860, Lenovo ThinkSystem SR650 V3 / SR850 V3, Supermicro X13 series, and Inspur NF5280M7, among others. Supported operating systems include Red Hat Enterprise Linux (RHEL) 8/9, SUSE Linux Enterprise Server (SLES) 15, Ubuntu Server 22.04 LTS, Microsoft Windows Server 2019/2022, and VMware vSphere 7.0/8.0. The processor supports IPMI 2.0 and Redfish management standards via compatible server BMCs. Memory compatibility spans RDIMM, LRDIMM, and 3DS RDIMM DDR5 modules at speeds up to DDR5-4800. Certifications relevant to this platform include ENERGY STAR compliance for server systems, NEBS readiness (platform-dependent), and broad FIPS 140-2 cryptographic module support through on-die cryptographic acceleration.

Ideal Use Cases

• AI & Machine Learning Inference: AMX and VNNI acceleration enable CPU-based inference for NLP, recommendation engines, and computer vision models, reducing GPU cluster costs for inference-heavy pipelines.
• Large-Scale Virtualisation: 48 cores and 96 threads per socket provide exceptional VM density in VMware vSphere, Microsoft Hyper-V, and KVM environments, with hardware-enforced VM isolation via TDX.
• In-Memory Databases & Analytics: SAP HANA, Oracle Database In-Memory, and Redis Enterprise benefit directly from the 150MB LLC and 300+ GB/s DDR5 memory bandwidth.
• High-Performance Computing (HPC): Scientific simulation, computational fluid dynamics (CFD), finite element analysis (FEA), and genomics pipelines leverage the wide AVX-512 FP64 throughput and massive core count.
• Cloud & Hyperscale Infrastructure: Multi-tenant cloud platforms and bare-metal-as-a-service providers benefit from per-core tuning via SST and hardware confidential computing via TDX for tenant isolation.
• Financial Services & Real-Time Risk: Low-latency mesh interconnect and large LLC support real-time derivatives pricing, Monte Carlo simulation, and fraud detection workloads requiring both speed and data security.
• Enterprise ERP & Database Consolidation: Consolidating multiple legacy application servers onto a dual-socket 8558P platform reduces rack space, licensing costs (per-core workloads), and operational overhead.
