Lenovo 4XG7A63427 SR630 V2 Gold 5318N 24C 150W 2.1GHZ

Lenovo 4XG7A63427 Intel Xeon Gold 5318N 24-Core Processor for ThinkSystem SR630 V2

Overview

The Lenovo 4XG7A63427 is a processor upgrade option pairing the Intel Xeon Gold 5318N with Lenovo's ThinkSystem SR630 V2 rack server platform. The 5318N is a 2nd Generation Intel Xeon Scalable processor aimed at workloads that demand high thread counts with moderate per-core frequency — making it a natural fit for virtualized environments, parallel data processing, and security-infrastructure back-end deployments where throughput per rack unit matters more than single-threaded clock speed. At 2.1 GHz base with a 3.4 GHz boost and 24 physical cores delivering 48 threads, this SKU targets the middle tier of the Xeon Gold 5000 family where price-to-core-count efficiency is strongest. If you are speccing a rack server for a video management system, analytics offload node, or enterprise compute backbone, the 4XG7A63427 is worth evaluating against your thread-density and TDP budget.

Key Features

• 24 Cores / 48 Threads via Intel Hyper-Threading: At 48 logical processors available to the OS, this CPU handles heavily multithreaded workloads — VMS recording services, concurrent analytics pipelines, and VM consolidation — without the per-core licensing cost premium that higher-bin Xeon Platinum parts carry. More threads available means fewer servers needed to absorb peak recording bursts from large camera counts.
• 2.1 GHz Base / 3.4 GHz Boost Frequency: The 1.3 GHz headroom between base and boost (via Intel Turbo Boost) lets the processor sprint on bursty, latency-sensitive tasks — forensic search, live analytics inference, storage indexing — while throttling back during steady-state recording to manage thermal output. This range is especially relevant in 1U/2U enclosures like the SR630 V2 where airflow is constrained.
• Priority Core Architecture — 8 High-Priority Cores at 2.3 GHz: Intel's Intelligent Performance capability within this processor designates 8 cores as high-priority at 2.3 GHz base, with the remaining 16 running at 2.0 GHz. For mixed workloads — where one process (live decoding or a database query) needs deterministic latency while background recording threads keep pace — this internal QoS layer is a meaningful architectural advantage over flat-frequency designs.
• 36 MB Last-Level Cache: 36 MB of L3 cache, distributed across 24 cores, reduces main-memory trips for working datasets that fit within that window. For in-memory analytics engines or database buffer pools feeding a security management platform, this cache depth sustains throughput without hammering DDR bandwidth.
• 11.2 GT/s System Bus (UPI): The Ultra Path Interconnect at 11.2 GT/s governs processor-to-processor and processor-to-platform communication. In dual-socket SR630 V2 configurations, this bus rate directly affects cross-socket memory latency and coherency overhead — keeping NUMA penalties manageable when software threads migrate between sockets under load.
• 10nm Process Node: Intel's 10nm fabrication geometry improves transistor density and power efficiency relative to the prior 14nm generation, contributing to the 5318N's 150W TDP. That ceiling matters when provisioning PDU capacity and UPS runtime in high-density racks — 150W is a known, plannable number.
• LGA 4189 Socket / 2nd Gen Xeon Scalable Platform: The LGA 4189 socket is the standard for the Ice Lake Xeon Scalable family. Pairing this processor with the SR630 V2 gives access to PCIe 4.0 lanes, DDR4-3200 memory channels, and the Optane persistent memory ecosystem — relevant if your workload can benefit from memory-tiering for large in-memory datasets or high-endurance storage caching.
• 64-Bit Operating Mode: Full 64-bit execution is standard here; no mixed-mode considerations. All modern hypervisors (VMware vSphere, Microsoft Hyper-V, KVM) and server OSes run in native 64-bit context, keeping memory addressability uncapped.

Integration and Compatibility

The 4XG7A63427 is a Lenovo factory-configured processor option for the Lenovo ThinkSystem SR630 V2 platform. The LGA 4189 socket ties this CPU exclusively to the Ice Lake Xeon Scalable server generation — it will not drop into prior-generation (Cascade Lake) platforms with the LGA 3647 socket. Confirm your SR630 V2 firmware is current before installation; Lenovo publishes minimum UEFI levels for new processor options through the ThinkSystem support portal. In dual-socket configurations, both sockets should carry matched processor SKUs for predictable NUMA behavior and thermal management. The 5318N's 48-lane PCIe 4.0 allocation (per socket) supports high-bandwidth add-in cards — GPU accelerators for video analytics, NVMe storage controllers, or 25/100GbE networking — without lane contention. For deployments building out a network video recorder or analytics server stack, the SR630 V2 with this processor provides the I/O backbone to support dense NVMe caching tiers alongside multi-GPU analytics cards.

Karl Wilson

The 4XG7A63427 lands in an interesting position in the Xeon Gold 5000 lineup — 24 cores at 150W is a relatively efficient package for workloads that need thread count over raw GHz. The priority core architecture (8 cores at 2.3 GHz, 16 at 2.0 GHz base) is something I'd want any integrator speccing a VMS server to understand before dismissing it as a minor firmware detail: if your VMS process scheduling is NUMA-aware, those 8 priority cores can be explicitly assigned to latency-sensitive decoding tasks while background indexing and analytics run on the lower-priority pool.

Technical Highlights:

• 48-Thread Throughput: 24 cores with Hyper-Threading gives the OS 48 schedulable threads — relevant when you're running a hypervisor hosting a VMS VM, a database VM, and an analytics VM simultaneously on a single SR630 V2 node. More logical processors reduce contention-driven latency spikes during peak recording events.
• 3.4 GHz Boost Ceiling: The 1.3 GHz delta between base (2.1 GHz) and boost (3.4 GHz) is the processor's burst headroom. In a 1U/2U chassis like the SR630 V2, sustained boost is thermally limited by airflow — don't spec this for workloads that need constant high-frequency execution. It's optimized for mixed steady-state plus burst patterns.
• 36 MB L3 Cache at 24 Cores: 1.5 MB per core is competitive at this tier. For a security analytics node running inference models or a PSIM platform with large in-memory event tables, this cache depth keeps hot dataset reads off the DDR bus, reducing memory controller pressure under concurrent access.

Deployment Considerations:

• The LGA 4189 socket is Ice Lake-exclusive. Before ordering, verify your SR630 V2 is a V2 chassis (not a V1/original SR630) and that system firmware meets Lenovo's minimum UEFI revision for the 5318N — mismatched firmware versions on new processor options are a common deployment stall point on Lenovo platforms.
• At 150W TDP, dual-socket configurations draw up to 300W from processor TDP alone before memory, storage, and NIC loads are factored in. Size your PDU circuits and UPS runtime calculations around a realistic full-server draw, not TDP alone — SR630 V2 peak system power under full load exceeds processor TDP by a significant margin.

This processor is well-suited for a mid-tier enterprise VMS or analytics server node where you need strong multithreaded throughput on a proven 1U/2U platform without moving to the higher-cost Xeon Platinum tier — particularly in deployments running 50–200 camera channels with concurrent server-side motion analytics or forensic search under a network video recorder architecture.
