Lenovo 4XG7A72937 ST650 V2 Gold 6346 16C 205W 3.1GHZ

Lenovo 4XG7A72937 Xeon Gold 6346 16-Core Server Processor

Overview

The Lenovo 4XG7A72937 is a factory-configured Intel Xeon Gold 6346 processor option for the ThinkSystem ST650 V2 tower server platform. Rated at 3.1 GHz base with a 3.6 GHz Turbo Boost ceiling, 16 cores, 32 threads, and a 205W TDP, this is a processor intended for compute-dense workloads where per-core throughput and memory bandwidth matter — database engines, virtualization hosts, and video analytics backends among them. It ships as a tray component (no cooler included), meaning it is ordered as a Lenovo-sourced server option rather than a retail boxed CPU. If you are expanding or initially specifying a Lenovo ThinkSystem ST650 V2 deployment, this is the qualified part number to order.

Key Features

• 16 Cores / 32 Threads (Ice Lake, 10nm): Intel's 3rd Generation Xeon Scalable architecture (codename Ice Lake) on 10nm delivers meaningful IPC gains over the previous generation. For a security or video analytics platform running deep-learning inference workloads alongside a network video recorder management stack, 32 logical threads give the OS scheduler genuine headroom to keep latency-sensitive processes responsive without CPU starvation.
• 3.1 GHz Base / 3.6 GHz Turbo Boost: The 3.1 GHz base is a hard, sustained frequency guarantee under full-core load — useful when sizing for worst-case throughput. The 3.6 GHz single-core boost matters for single-threaded tasks like VMS stream decoding pipelines that are not yet fully parallelized.
• 36 MB L3 Cache: 36 MB of last-level cache reduces main-memory round trips on working sets that fit within it — relevant for in-memory databases, analytics engines, and high-channel-count video processing where repeated access to frame buffers or metadata indexes is common.
• 205W TDP: At 205W, this processor requires a server platform rated for high-TDP Xeon Scalable parts. The ST650 V2 is qualified for it, but thermal planning is non-negotiable — confirm your rack cooling capacity before deployment. Do not drop this into a chassis that is only validated for sub-165W Ice Lake parts.
• 11.2 GT/s System Bus Rate (LGA 4189 Socket): The 11.2 GT/s UPI interconnect rate on the LGA 4189 platform supports high-bandwidth memory configurations. For workloads that are memory-bandwidth-bound — large dataset analytics, video stream buffering, parallel AI inference — this interconnect ceiling is the limiting factor, so pairing with appropriate DDR4-3200 DIMMs is important to realize full throughput.
• 64-bit Operating Mode: Supports full 64-bit operating modes, which is the baseline requirement for any modern enterprise OS (VMware ESXi, Windows Server, Red Hat, Ubuntu Server). No 32-bit legacy constraints apply.
• Tray Package (No Cooler): Shipped as a tray component — there is no retail heatsink in the box. Cooling is handled by the ST650 V2 chassis. This is the correct procurement format for a server platform build, not a standalone workstation upgrade.

Integration and Compatibility

The 4XG7A72937 is a Lenovo-qualified option for the ThinkSystem ST650 V2, using the LGA 4189 socket shared across the 3rd Generation Intel Xeon Scalable family. Compatibility is governed by Lenovo's Hardware Compatibility List (HCL) for that platform — do not assume cross-platform compatibility with other OEM server lines using the same socket without verifying the HCL for each target chassis. For IP camera infrastructure builds where the ST650 V2 is serving as a video analytics or VMS backend, validate that your VMS vendor supports the specific OS version you plan to run on this processor generation before ordering. No cooler, retention bracket, or thermal compound is included — the ST650 V2 platform provides chassis-integrated cooling. Confirm your chassis configuration includes the appropriate fan and airflow kit for 205W-class processors.

Frequently Asked Questions

Q: What server platform is the Lenovo 4XG7A72937 compatible with?

A: The 4XG7A72937 is a qualified processor option for the Lenovo ThinkSystem ST650 V2 tower server. It uses the LGA 4189 socket. Compatibility with other platforms should be verified against Lenovo's Hardware Compatibility List for each target chassis.

Q: Does the Lenovo 4XG7A72937 include a cooler?

A: No. This processor ships as a tray component with no heatsink or cooling solution included. The ThinkSystem ST650 V2 provides chassis-integrated cooling designed for high-TDP Xeon Scalable processors.

Q: What is the TDP of the Xeon Gold 6346 in this configuration?

A: The Xeon Gold 6346 in the 4XG7A72937 has a Thermal Design Power (TDP) of 205W. Confirm that your server chassis and rack cooling are rated for this thermal envelope before deployment.

Q: How many cores and threads does the 4XG7A72937 provide?

A: The Xeon Gold 6346 delivers 16 physical cores and 32 threads (via Intel Hyper-Threading), running at 3.1 GHz base and boosting to 3.6 GHz on a single core under light load.

Q: What processor generation and architecture is this?

A: The Xeon Gold 6346 is a 3rd Generation Intel Xeon Scalable processor, based on the Ice Lake microarchitecture, manufactured on a 10nm process node.

Q: Is the 4XG7A72937 suitable for use as a video management system (VMS) server?

A: Yes, the 16-core/32-thread configuration with 36 MB cache and 3.1 GHz base clock makes the Xeon Gold 6346 a viable compute platform for high-channel-count VMS deployments. Verify your VMS vendor's hardware requirements and supported OS list against the ST650 V2 platform specifications before finalizing the build.

The 4XG7A72937 puts the Xeon Gold 6346 — a 16-core, 205W Ice Lake part running at 3.1 GHz sustained — into the Lenovo ThinkSystem ST650 V2 platform. That 205W TDP is the first thing I look at on any server CPU spec for a video analytics deployment: it tells you this is not a low-power edge box, it is a full data-center-class compute node, and your rack needs to be treated as such.

Technical Highlights:

• 16C/32T at 3.1 GHz base: 32 logical threads give a VMS or analytics backend genuine CPU scheduling room. Under sustained full-core load, 3.1 GHz is the guaranteed floor — not a marketing burst number — which matters when you are sizing for worst-case concurrent stream decode.
• 36 MB L3 Cache: For deep-learning inference pipelines that repeatedly access model weights and frame buffers, 36 MB of last-level cache reduces DDR4 round trips and helps keep per-frame latency consistent, especially as channel counts climb toward the platform maximum.
• 11.2 GT/s UPI / LGA 4189: The UPI interconnect rate on this platform sets the ceiling for multi-socket memory bandwidth. If you are running a memory-bandwidth-heavy workload — parallel analytics across dozens of 4K streams — pairing with correctly-rated DDR4-3200 DIMMs is not optional; under-speccing the memory tier will leave this CPU waiting on data.

Deployment Considerations:

• No cooler is included — this is a tray-format component. The ST650 V2 chassis provides the thermal solution, but verify that the specific fan kit installed in your chassis configuration is rated for 205W-class Xeon Scalable processors before powering on.
• Confirm your VMS or analytics software vendor's HCL explicitly lists the ST650 V2 or Ice Lake Xeon Scalable as a supported platform — some older VMS versions have quirks with 3rd Gen Xeon memory controller behavior under high channel counts.

This processor option is the right pick for an ST650 V2 being provisioned as a centralized VMS recording and analytics server in a mid-to-large enterprise physical security deployment — one running 64+ camera channels with concurrent AI-based motion analytics where per-core throughput at sustained load is the design constraint.
