Lenovo 4XG7A91481 Intel Xeon Silver 4516Y+ 24-Core Processor Option for ThinkSystem SR630 V3

Overview

The Lenovo 4XG7A91481 is an Intel Xeon Silver 4516Y+ processor option kit designed specifically for the ThinkSystem SR630 V3 rack server. Built on Intel's 5th Gen Xeon Scalable architecture (codename Emerald Rapids), this 24-core, 48-thread processor targets workloads that demand balanced compute density and memory bandwidth without the power overhead of Xeon Gold or Platinum tiers. At 2.2 GHz base with a 3.7 GHz boost ceiling and a 185W TDP, it fits enterprise environments where you need serious core counts for parallel workloads — video analytics processing, security operations center infrastructure, VMS server back-ends, or general enterprise compute — while keeping per-socket power draw predictable for rack power planning.

This is a genuine Lenovo server processor option sourced through authorized distribution channels — factory-new, no grey-market, no parallel imports. If you're configuring or expanding a rack server deployment, this option integrates directly into the SR630 V3 platform without modification.

Key Features

• 24 Cores / 48 Threads (Emerald Rapids): Intel's 5th Gen Xeon Scalable architecture delivers 24 physical cores and 48 logical threads per socket. For multi-threaded workloads — VMS recording servers, AI-assisted video analytics, or enterprise virtualization hosts — more threads mean more concurrent streams or VMs before the CPU becomes the bottleneck. Emerald Rapids brings architectural improvements over prior Sapphire Rapids generation for per-core throughput.
• 2.2 GHz Base / 3.7 GHz Boost Frequency: The base clock handles sustained all-core workloads (long-running encoding, database queries) while the 3.7 GHz boost handles bursty single-threaded tasks without you having to overprovision. In practice, a VMS server running motion analytics on 64+ channels benefits from a processor that can sustain all-core loads without thermal throttling.
• 45 MB L3 Cache: 45 MB of shared L3 cache reduces main memory latency for frequently accessed data structures. For in-memory databases, caching layers, or video frame buffers, a larger L3 keeps hot data closer to execution units — translating to lower latency per operation at scale.
• 185W TDP — Predictable Power Planning: A defined 185W thermal design power envelope means your rack PDU and cooling calculations are deterministic. No guesswork for power budget per 1U slot. For dense deployments with dual-socket configurations or high-density racks, knowing exactly what each processor draws prevents oversubscription surprises at the PDU level.
• 48 PCIe Lanes via LGA 4677 (Socket E): The LGA 4677 socket and 5th Gen Xeon platform provide high-speed PCIe connectivity for NVMe storage, GPU accelerators, or high-throughput network cards. For network-intensive deployments or AI inference workloads requiring GPU offload, the platform's I/O bandwidth is not the limiting factor.
• 16 GT/s Intel UPI Speed: In dual-socket SR630 V3 configurations, the 16 GT/s Ultra Path Interconnect links both processors with high-bandwidth, low-latency coherency fabric. Workloads that span both sockets — large in-memory datasets, NUMA-aware applications — benefit from faster cross-socket data transfer compared to prior-generation UPI speeds.
• 3.7 GHz Single-Core Boost for Latency-Sensitive Tasks: Not all workloads are parallel. License-plate recognition engines, facial recognition inference, and access control event processing often run single-threaded decision loops. The 3.7 GHz boost frequency ensures those tasks get resolved quickly before handing off to downstream systems.
• 64-Bit Operating Mode / Stepping R1: Full 64-bit addressing supports large memory configurations required by modern hypervisors and in-memory analytics platforms. Stepping R1 indicates a mature silicon revision — relevant for production deployments where microcode stability matters more than being first to market on a new stepping.

Integration and Compatibility

The 4XG7A91481 is validated for the Lenovo ThinkSystem SR630 V3 platform using the LGA 4677 (Socket E) socket. It is not compatible with prior-generation SR630 V2 or other ThinkSystem platforms using different socket types — verify your server's socket and platform generation before ordering. The SR630 V3 supports both single- and dual-socket configurations; this processor option covers one socket. For dual-socket builds, a second 4XG7A91481 or a compatible Xeon Silver/Gold option is required for the second socket.

As an Intel Xeon Silver 4000 Series part, this processor supports the full DDR5 memory ecosystem available on the SR630 V3 platform, including high-capacity RDIMMs for memory-intensive workloads. Pair with compatible server memory modules and a validated heatsink — note that no cooler is included with this option kit; a separate heatsink must be specified for the SR630 V3 chassis configuration. Country of origin is Mexico (MX); UNSPSC code 43201503 for procurement systems.

Frequently Asked Questions

Q: Is the 4XG7A91481 compatible with the Lenovo ThinkSystem SR630 V2?

A: No. The 4XG7A91481 uses the LGA 4677 (Socket E) socket and is validated for the ThinkSystem SR630 V3 only. The SR630 V2 uses a different socket generation and is not compatible with 5th Gen Xeon Scalable processors.

Q: Does the 4XG7A91481 include a heatsink or cooler?

A: No. The cooler is not included with this processor option kit. A separate heatsink validated for the SR630 V3 chassis must be ordered to complete the installation.

Q: What is the TDP of the Intel Xeon Silver 4516Y+ in the 4XG7A91481?

A: The processor has a Thermal Design Power (TDP) of 185W. Ensure your SR630 V3 power supply and chassis cooling configuration are rated to support this TDP, particularly in dual-socket builds.

Q: Can this processor be used in a dual-socket SR630 V3 configuration?

A: Yes, the SR630 V3 supports dual-socket configurations. The 4XG7A91481 covers one socket. A second compatible processor option must be ordered separately for the second socket.

Q: What Intel processor generation is the Xeon Silver 4516Y+?

A: The Xeon Silver 4516Y+ is Intel's 5th Gen Xeon Scalable processor, codenamed Emerald Rapids, built on the LGA 4677 platform. It succeeds the 4th Gen Sapphire Rapids generation with architectural improvements for per-core throughput and platform efficiency.

Q: What is the maximum boost frequency of the Xeon Silver 4516Y+ in the 4XG7A91481?

A: The processor boosts to a maximum of 3.7 GHz on a single core under Turbo Boost, with a base all-core frequency of 2.2 GHz.

Ted Perry

The 4XG7A91481 is a purpose-matched processor option for integrators deploying the ThinkSystem SR630 V3 as the compute backbone of a large-scale video analytics or enterprise security operations platform. The 24-core Xeon Silver 4516Y+ at 185W TDP hits a specific design point: maximum thread count within a predictable power envelope, which matters when you're sizing rack PDUs for a multi-server deployment.

Technical Highlights:

• 24 Cores / 48 Threads at 185W: Delivers 0.13 threads per watt — a meaningful ratio when you're running concurrent VMS recording, analytics inference, and database workloads on the same host. Keeps per-socket power draw bounded without sacrificing parallelism.
• 3.7 GHz Turbo Boost: Single-threaded event processing — access control decisions, alarm correlation, real-time analytics triggers — resolves faster at boost speeds. The 1.5 GHz spread between base and boost (2.2 to 3.7 GHz) gives this processor more headroom than typical flat-frequency server chips.
• 45 MB L3 Cache + 16 GT/s UPI: In dual-socket SR630 V3 configs, 16 GT/s UPI fabric keeps cross-socket cache coherency latency low. Combined with 45 MB of L3 per socket, workloads that share data across NUMA nodes — typical in large VMS deployments — see less memory fetch penalty than prior-generation platforms.

Deployment Considerations:

• No cooler is included — this is a common ordering oversight. Confirm the heatsink option for your SR630 V3 chassis configuration (standard vs. high-performance) is in your BOM before the server ships. Missing the heatsink delays commissioning.
• Verify your SR630 V3 firmware and Lenovo XClarity Provisioning Manager version support Emerald Rapids stepping R1 before installation. Older firmware images may not recognize 5th Gen Xeon Scalable processors correctly.

This option is the right call for a single-socket SR630 V3 build targeting sustained multi-threaded compute — specifically a centralized VMS server handling 64–128 camera streams with edge analytics offloaded to the CPU rather than a GPU. For AI inference-heavy workloads requiring GPU acceleration, evaluate adding a PCIe accelerator card alongside this processor rather than stepping up to a higher TDP Xeon Gold SKU.
