Lenovo 4XG7A63477 SR650 V2 Gold 5315Y 8C 140W 3.2GHZ

Lenovo 4XG7A63477 Intel Xeon Gold 5315Y 8-Core Processor Option for ThinkSystem SR650 V2

Overview

The Lenovo 4XG7A63477 is a factory-configured processor option kit supplying an Intel Xeon Gold 5315Y to the ThinkSystem SR650 V2 rack server platform. Targeting workloads that demand reliable multi-threaded compute without the overhead of high-core-count dies — think video management server back-ends, NVR host platforms, or edge analytics nodes — this 8-core Ice Lake processor hits a well-balanced point in the Xeon Gold 5000 series lineup. At 3.2 GHz base with a 3.6 GHz boost and a 140W thermal envelope, it delivers predictable throughput without requiring the aggressive cooling infrastructure of higher-TDP parts.

Built on Intel's third-generation Xeon Scalable architecture (Ice Lake, 10nm), the 5315Y occupies the LGA 4189 socket of the SR650 V2, making it a direct installation into Lenovo's two-socket enterprise chassis. For integrators speccing a VMS appliance, analytics server, or AI-inferencing node that will run 24/7 in a data center or wiring closet, the 4XG7A63477 option kit is the path to a Lenovo factory-supported bill of materials rather than a field-sourced part.

Key Features

• 8 Cores / 16 Threads at 3.2 GHz Base: The 5315Y's 8-core, 16-thread configuration handles concurrent VMS recording, analytics, and management processes without the context-switching overhead that throttles single-threaded platforms. A typical 64-channel NVR workload with motion analytics runs comfortably within this core count, leaving headroom for OS and management services.
• 3.6 GHz Turbo Boost: When workloads serialize — license plate recognition bursts, forensic video exports, report generation — the processor steps up to 3.6 GHz automatically. That 400 MHz headroom matters on latency-sensitive operations where wall-clock time directly affects operator response.
• 140W TDP on a Controlled Thermal Budget: At 140W, the 5315Y sits in a mid-range thermal envelope for the Gold 5000 series. The SR650 V2 chassis is rated for it, but integrators adding a second processor or high-density GPU cards should verify total chassis power draw against available PDU capacity before commissioning.
• 12MB L3 Cache: The 12MB last-level cache keeps frequently accessed codec tables, analytics model weights, and frame buffers closer to the execution units. In continuous-decode scenarios — playing back 4K streams across multiple VMS workstations — cache locality directly reduces memory bus pressure.
• DDR4-SDRAM Memory Support: The 5315Y supports DDR4-SDRAM, the standard memory technology for the SR650 V2 platform. DDR4's broad ecosystem means straightforward memory procurement and compatibility across Lenovo's validated DIMM list — no hunting for exotic memory specs.
• 11.2 GT/s System Bus: The 11.2 GT/s UPI interconnect rate sustains high-bandwidth communication between the processor, memory controllers, and PCIe fabric. For storage-heavy VMS configurations with multiple NVMe drives or a RAID controller, bus throughput is a real bottleneck limiter — this spec keeps it out of the critical path.
• 10nm Ice Lake Architecture: Third-generation Xeon Scalable (Ice Lake) adds AVX-512 instruction support relevant to AI inference workloads — object detection, face recognition, behavioral analytics. If your VMS stack uses Intel OpenVINO or similar frameworks, this architecture is on the supported path.
• LGA 4189 Socket, SR650 V2 Platform: The LGA 4189 socket is specific to the third-generation Xeon Scalable family on the SR650 V2. This is not a universal upgrade part — it installs only in SR650 V2 systems configured for this socket generation. Verify the target chassis before ordering.

Integration & Compatibility

The 4XG7A63477 is designed as a Lenovo factory option for the Lenovo ThinkSystem SR650 V2 platform. It installs into the LGA 4189 primary or secondary processor socket and is validated against Lenovo's firmware and thermal management stack for that chassis. Pairing with Lenovo-validated DDR4 DIMMs and the SR650 V2's onboard XClarity management is the supported configuration path for enterprise deployments.

For network video recorder and VMS appliance builds, the SR650 V2 running this processor supports standard x86 VMS platforms including Milestone XProtect, Genetec Security Center, and Avigilon Control Center — all of which publish validated server hardware lists that reference the SR650 V2 chassis. Confirm your VMS vendor's hardware compatibility guide against this CPU-chassis combination before finalizing the BOM.

Integrators deploying IP camera infrastructure at scale — 64 channels and above — should evaluate total storage I/O alongside processor selection. A network switch with adequate PoE budget feeding cameras back to this server platform is part of the complete system design; the processor spec alone does not determine recording capacity. Refer to a server and storage planning guide for retention calculations that align with your channel count and resolution mix.

When I spec a VMS appliance platform, the processor selection usually comes down to two questions: does the core count handle concurrent stream decode and analytics without saturation, and does the TDP fit the chassis power budget without surprises at install time. The Lenovo 4XG7A63477 — pairing an 8-core Xeon Gold 5315Y at 3.2 GHz with a 140W envelope — lands in a practical middle ground for mid-scale deployments where you're not running a 200-channel Genetec farm, but you need more than a 4-core edge box can deliver reliably.

Technical Highlights:

• 8C/16T at 3.2–3.6 GHz: Sixteen threads at up to 3.6 GHz handles simultaneous recording, analytics, and operator playback without the scheduling contention that shows up as VMS stuttering on under-provisioned systems.
• 12MB L3 Cache: Keeps codec tables and analytics model data resident in cache rather than bouncing to DDR4 on every frame — measurable in sustained multi-stream decode benchmarks, particularly at 4K stream density.
• AVX-512 via Ice Lake (10nm): Third-gen Xeon Scalable's AVX-512 support means OpenVINO-based analytics — object classification, people counting, LPR — execute on the CPU without requiring a discrete inference card, keeping the BOM leaner on sub-64-channel deployments.

Deployment Considerations:

• The LGA 4189 socket is exclusive to third-generation Xeon Scalable on the SR650 V2 — confirm the chassis generation before issuing a PO, since SR650 (gen 1) and SR650 V2 are not socket-compatible.
• At 140W TDP, a dual-processor SR650 V2 build pulls 280W in processor load alone. Factor full chassis TDP (drives, RAM, NICs, GPU if present) against rack PDU capacity and UPS sizing before commissioning — this is the spec that most often surprises integrators in dense rack deployments.

This option fits best in a 32–96 channel VMS appliance build on the SR650 V2 where the workload is a mix of continuous recording and CPU-based analytics — enough cores to absorb both without over-provisioning into a high-core-count die that adds cost without utilization.
