Lenovo 4XG7A63456 SR650 V2 Gold 5317 12C 150W 3.0GHZ

Lenovo 4XG7A63456 Intel Xeon Gold 5317 12-Core Processor for ThinkSystem SR650 V2

Overview

The Lenovo 4XG7A63456 is a factory-configured Intel Xeon Gold 5317 processor option for the ThinkSystem SR650 V2 rack server — a 12-core, 3rd Generation Intel Xeon Scalable part running at 3.0 GHz base with a 3.6 GHz Turbo Boost ceiling, all within a 150W TDP envelope. If you're sizing a mid-tier compute node for video management workloads, AI inferencing on the edge, or virtualized security infrastructure, this CPU lands in the performance tier that handles sustained multi-threaded work without pushing the thermal and power budget of a higher-core-count Gold or Platinum part. The 10 nm Ice Lake architecture delivers meaningful per-core IPC gains over prior Cascade Lake generations — relevant when your VMS or analytics engine is single-thread-sensitive.

Key Features

• 12 Cores / 24 Threads at 3.0 GHz Base: The 5317 gives you 24 logical threads via Hyper-Threading, which matters when running concurrent VMS streams, analytics pipelines, and OS overhead on the same socket. The 3.0 GHz base frequency is consistent under full load — you're not relying on short-burst Turbo to sustain throughput.
• 3.6 GHz Turbo Boost: Single- and lightly-threaded tasks — license plate recognition inference calls, database queries, alarm event processing — get a 20% clock bump above base when thermal headroom allows. On a well-cooled SR650 V2, that headroom is reliably available.
• 18 MB L3 Cache: The on-die cache reduces memory latency for workloads with hot working sets. Video analytics models and frame buffers that fit in L3 avoid the latency penalty of going out to DDR4 DRAM, keeping per-frame processing tighter and more deterministic.
• 150W TDP: Positioned in the mid-range of the Xeon Gold 5000 series power envelope. The SR650 V2's cooling and power subsystem is rated for dual-socket configurations at this TDP — so if you're running single-socket today, you have clean headroom to add a second 4XG7A63456 or a different Gold processor to double compute capacity without a chassis change.
• LGA 4189 Socket (Ice Lake): The Ice Lake platform's LGA 4189 socket supports PCIe 4.0, doubling the bandwidth available to GPU accelerators, NVMe storage, and high-throughput network cards compared to the previous LGA 3647 platform. For GPU-assisted video analytics, this bandwidth difference is non-trivial.
• Up to 6 TB Addressable Memory: The processor's memory controller supports up to 6 TB of RAM per socket — far beyond what any current analytics workload needs, but it means you're not boxing yourself in if the deployment scales toward in-memory databases, large model inference, or high-channel NVR buffering.
• 64-Bit / 11.2 GT/s System Bus: The 11.2 GT/s UPI (Ultra Path Interconnect) bus rate governs NUMA coherency in dual-socket configurations. For workloads that share data across sockets — shared VMS databases, cross-socket GPU memory — a faster UPI rate reduces cross-socket latency.
• 3rd Gen Xeon Scalable (Ice Lake) Architecture: Ice Lake adds built-in Intel DL Boost (VNNI instructions) for accelerating INT8 inference workloads without a separate AI accelerator card. If your analytics stack supports AVX-512 VNNI, inference throughput on neural network models can improve substantially versus older Cascade Lake processors running the same workload.

Integration and Compatibility

The 4XG7A63456 is a Lenovo-configured processor option specifically validated for the ThinkSystem SR650 V2 platform. Processor compatibility in enterprise servers is not interchangeable across generations — confirm the SR650 V2 system board revision and existing processor population before ordering. In dual-socket SR650 V2 deployments, both processor sockets must be populated with identical or compatible processors per Lenovo's validated configuration matrix.

For network video recorder and VMS server builds, pair this CPU with adequate DDR4 RDIMM capacity and sufficient PCIe 4.0 slot allocation for storage HBAs or GPU cards depending on analytics requirements. The platform's PCIe 4.0 support ensures current-generation NVMe drives and inference accelerators won't be bandwidth-constrained at the CPU interface. Review your network switching topology alongside compute sizing — camera channel count determines both storage IOPS and CPU decode thread requirements simultaneously.

Frequently Asked Questions

Q: What server platform is the Lenovo 4XG7A63456 designed for?

A: The 4XG7A63456 is a Lenovo-configured Intel Xeon Gold 5317 processor option validated for the ThinkSystem SR650 V2 rack server platform. It uses the LGA 4189 socket and is part of the 3rd Generation Intel Xeon Scalable (Ice Lake) family.

Q: What are the base and boost clock speeds of the Xeon Gold 5317 in this configuration?

A: The processor runs at 3.0 GHz base frequency with a Turbo Boost ceiling of 3.6 GHz. The boost frequency applies to single- and lightly-threaded workloads when thermal headroom is available.

Q: How many cores and threads does this processor provide?

A: The Intel Xeon Gold 5317 provides 12 physical cores and 24 logical threads via Intel Hyper-Threading Technology, operating in 64-bit mode.

Q: What is the TDP of this processor, and can the SR650 V2 handle dual-socket configurations at this power level?

A: The processor has a 150W Thermal Design Power (TDP). The ThinkSystem SR650 V2 is designed to support dual-socket configurations, so a second processor at this TDP level can be added without a chassis change, provided power supply and cooling configurations are appropriate.

Q: Does the Ice Lake architecture provide any benefit for video analytics workloads?

A: Yes. The 3rd Generation Xeon Scalable (Ice Lake) architecture includes Intel DL Boost with AVX-512 VNNI instructions, which can accelerate INT8 neural network inference workloads without a separate AI accelerator card — relevant for on-server video analytics.

Q: What is the maximum memory supported by this processor?

A: The Intel Xeon Gold 5317 supports up to 6 TB of internal memory per socket, providing substantial headroom for memory-intensive VMS, database, or analytics workloads.

James Everett

The Lenovo 4XG7A63456 slots into a specific tier of server compute that I see underspecified frequently in VMS deployments: you need more than a basic 8-core entry part to handle concurrent decode and analytics, but you don't need — or want to pay for — a 28-core Platinum processor with 205W TDP and the associated cooling requirements. The 5317's 12-core, 150W profile hits that middle band cleanly on the SR650 V2 platform.

Technical Highlights:

• 3.0 GHz Base / 3.6 GHz Boost: In VMS workloads, consistent base frequency matters more than peak Turbo. The 5317 sustains 3.0 GHz across all 12 cores under full load — you won't see clock throttling on a properly configured SR650 V2 with adequate airflow.
• Intel DL Boost (AVX-512 VNNI): Ice Lake's built-in inference acceleration is worth benchmarking before you commit to a GPU add-in card for analytics. For lighter inference models (people detection, basic object classification), the on-CPU VNNI path can handle the load without the added cost and slot consumption of a PCIe accelerator.
• PCIe 4.0 via LGA 4189: The platform upgrade from LGA 3647 to LGA 4189 doubles PCIe bandwidth. If you're attaching NVMe arrays for high-channel video retention or a GPU for deep learning inference, this is the generation where that bus stops being a bottleneck.

Deployment Considerations:

• Confirm dual-socket compatibility before ordering a second unit: the SR650 V2 requires matched or validated processor pairs per Lenovo's configuration guide — mixing processor stepping or TDP classes in the same chassis can create validation issues that surface only under load.
• At 150W TDP, thermal management in a high-density rack is non-trivial. Verify the SR650 V2's fan and PSU configuration is rated for dual 150W processors if you're planning a two-socket build — don't assume the base chassis configuration covers it without checking the Lenovo Power Configurator output.

For a purpose-built VMS server handling 64–128 IP camera channels with concurrent motion search and edge analytics offload, the 4XG7A63456 in a single-socket SR650 V2 configuration with adequate DDR4 and NVMe storage is a well-balanced starting point — with a clear dual-socket upgrade path when channel counts grow.
