Lenovo 4XG7A72932 Intel Xeon Gold 6326 16-Core Processor for ThinkSystem ST650 V2

Overview

The Lenovo 4XG7A72932 is a factory-new Intel Xeon Gold 6326 processor option kit designed specifically for the Lenovo ThinkSystem ST650 V2 tower server. Built on Intel's 3rd Generation Xeon Scalable architecture (Ice Lake, 10nm), the Gold 6326 delivers 16 physical cores, 32 threads, and a 2.9 GHz base clock with a 3.5 GHz boost — a combination that handles mixed enterprise workloads including virtualization, database services, and compute-intensive applications without throttling under sustained load. If you're speccing a ST650 V2 for a workload that demands both core density and per-core clock speed, this is a processor worth evaluating carefully before defaulting to a higher core-count option at lower frequencies.

Lenovo server components like the 4XG7A72932 are sourced factory-new and designed to integrate cleanly into the ThinkSystem ecosystem without compatibility guesswork. This is a genuine Lenovo option kit — not a loose retail CPU — meaning it arrives tested and validated for the ST650 V2 platform.

Key Features

• 16 Cores / 32 Threads at 2.9 GHz Base: The 6326's 16-core, 32-thread configuration handles concurrent VM instances or parallel database queries without the frequency penalty you'd see on higher core-count Xeon Platinum SKUs. At 2.9 GHz base with 3.5 GHz single-core boost, latency-sensitive workloads — OLTP, real-time analytics, VMS event processing — stay responsive under load.
• Intel Speed Select Technology — Priority Core Tiering: The 6326 implements Intel Speed Select with 4 high-priority cores running at 3.0 GHz and 12 standard cores at 2.6 GHz base. This means latency-critical threads get preferential clock allocation automatically — relevant for video management software (VMS) platforms that mix real-time decode threads with background indexing tasks.
• 3.5 GHz Single-Core Turbo Boost: For single-threaded or lightly threaded applications — legacy security software, licensing servers, domain controllers running alongside heavier workloads — the 3.5 GHz peak frequency ensures those tasks don't become the bottleneck in a shared environment.
• 24 MB L3 Cache: The 24 MB shared last-level cache reduces memory latency for working datasets that fit within that boundary. In a VMS context, this can improve live-stream decode performance when the server handles a high camera count without hitting DRAM bandwidth limits on every frame.
• 185W TDP — Power Planning Required: At 185W, this is a high-power processor option. The ST650 V2's cooling and power delivery are validated for this TDP, but if you're deploying in an environment with shared power circuits or UPS headroom constraints, account for full TDP under load. This is not a fit-and-forget detail — model it before rack installation. For UPS and power protection options sized for server deployments, review that category separately.
• LGA 4189 Socket, 10nm Ice Lake Architecture: The LGA 4189 socket supports DDR4-3200 memory and PCIe 4.0, which means the ST650 V2 platform can leverage faster NVMe storage and higher-bandwidth expansion cards. If your deployment includes GPU-accelerated analytics or high-throughput network adapters, PCIe 4.0 headroom matters.
• 11.2 GT/s System Bus: The 11.2 GT/s UPI interconnect speed is relevant in dual-socket configurations — inter-socket memory access latency stays lower than on prior-gen platforms, which helps workloads that don't fit cleanly in a single socket's NUMA domain.
• 64-bit Operating Mode, 32 Threads: Full 64-bit support is a baseline expectation for any enterprise server processor in 2024, but the 32-thread count is the practical number for hypervisor vCPU allocation. A single 6326 can support 32 vCPUs before over-subscription — enough for mid-density virtualization without a second socket.

Integration & Compatibility

The 4XG7A72932 is a Lenovo option kit validated for the ThinkSystem ST650 V2 tower server platform. It installs into the LGA 4189 socket and is compatible with the ST650 V2's thermal solution and power delivery as configured from Lenovo. This processor is not a standalone purchase for generic LGA 4189 motherboards — it is a Lenovo-validated component for this specific platform. Confirm your ST650 V2 configuration supports the 185W processor option before ordering; some base configurations require a firmware update or upgraded cooling module for full TDP support.

For enterprise deployments integrating this server into a network video recorder or VMS infrastructure, the ST650 V2 with this processor provides sufficient compute for high-channel-count video analytics, particularly where on-premise AI inference is part of the architecture. For network switching to support a high-bandwidth server deployment, ensure uplink capacity matches your camera or storage I/O throughput requirements.

The UNSPSC code for this component is 43201503 (computer processor). This is a commercial-grade server processor kit intended for enterprise and commercial environments.
