Lenovo 4XG7A72936 ThinkSystem ST650 V2 Intel Xeon Platinum 8352Y 32-Core Processor Option

Overview

The Lenovo 4XG7A72936 is a factory-new processor option kit pairing the 3rd Generation Intel Xeon Platinum 8352Y with the ThinkSystem ST650 V2 tower server. At 32 cores, 64 threads, and a base clock of 2.2 GHz that turbo-boosts to 3.4 GHz, this is a serious compute upgrade for organizations running enterprise servers that need headroom for concurrent workloads — VMS analytics engines, database services, virtualized security infrastructure, or dense application hosting. If you are speccing a Lenovo ThinkSystem platform for a project that demands both throughput and predictable latency under mixed load, the 8352Y's hybrid core architecture is the configuration to understand before you finalize your BOM.

The 4XG7A72936 is a channel-sourced, genuine Lenovo option kit — not a grey-market or parallel-import part. It is designed and validated specifically for the ST650 V2 platform and carries Lenovo's processor option compatibility assurance for that system.

Key Features

• 32 Cores / 64 Threads at 2.2 GHz Base: Running 64 simultaneous threads on a single socket keeps your ST650 V2 relevant across multi-tenant VM deployments and parallel processing pipelines. For a VMS host running Milestone XProtect or Genetec with deep-learning analytics on dozens of camera streams, core count is where you stop the bottleneck before it starts.
• 3.4 GHz Turbo Boost: The 8352Y's peak single-thread frequency of 3.4 GHz matters when workloads like database queries, authentication services, or VMS event correlation serialize into short, latency-sensitive bursts. You get high-throughput baseline plus burst headroom — not a flat-clock compromise.
• Hybrid Priority Core Architecture — 12 High-Priority + 20 Efficiency Cores: Intel's 3rd Gen Xeon Scalable splits the die into 12 high-priority cores running at 2.4 GHz and 20 efficiency cores at 2.0 GHz. Schedulers that are priority-core-aware can route latency-sensitive threads to the 2.4 GHz cluster, leaving the 2.0 GHz cores for background tasks like log ingestion, archival I/O, and housekeeping services. This is a meaningful architectural advantage for mixed-workload servers that historically required two separate VMs to isolate latency from throughput.
• 48 MB L3 Cache: A 48 MB on-die cache reduces DRAM round-trips for working datasets — particularly relevant for in-memory analytics, large database buffer pools, and NVR index tables where repeated access to a hot dataset dominates performance. More cache means fewer cycles waiting on memory controllers.
• 11.2 GT/s System Bus: The UPI interconnect at 11.2 GT/s ensures that on a dual-socket ST650 V2 configuration, inter-socket cache coherency and memory access don't become the bandwidth ceiling. For workloads that span both sockets, this keeps NUMA penalties manageable.
• 64-Bit Operating Mode, LGA 4189 Socket: The LGA 4189 platform is the standard socket for Ice Lake Xeon Scalable processors. Compatibility with the ST650 V2 is by design — Lenovo validates processor option kits against the system firmware and thermal envelope before release, so you are not integrating a bare retail chip into an unvalidated thermal stack.
• Intel 10nm (Intel 7) Lithography: The 3rd Gen Xeon Scalable's 10nm process node delivers improved performance-per-watt compared to the prior 14nm generation. At 205W TDP you are drawing real power, but you are extracting substantially more compute per watt than the equivalent 2nd Gen configuration — relevant when you are scaling rack density or managing datacenter power allocations.
• 205W TDP: This is not a low-power part. At 205W, the ST650 V2 needs adequate airflow and power supply headroom. If your rack or room cooling is already at capacity, validate thermal budget before ordering. If your infrastructure supports it, 205W buys you all 32 cores running at speed — no throttling, no power-capping compromises.

Integration & Compatibility

The 4XG7A72936 is validated for the Lenovo ThinkSystem ST650 V2 platform. Xeon Platinum 8352Y is a member of the Intel Xeon Platinum 8000 Series within the 3rd Generation Intel Xeon Scalable family (Ice Lake-SP), which is supported on the LGA 4189 socket ecosystem. Deployment in environments using VMware vSphere, Microsoft Hyper-V, or Red Hat KVM is standard — all three hypervisors have mature support for Ice Lake Xeon Scalable. For network video recorder or VMS server builds, the 32-core / 64-thread configuration supports high camera-count deployments with concurrent deep-learning analytics without saturating the CPU — particularly relevant when analytics are offloaded to the host CPU rather than a dedicated GPU. Confirm system firmware revision compatibility with Lenovo's ServerProven database for your specific ST650 V2 chassis configuration before installation.

Frequently Asked Questions

Q: What server platform is the Lenovo 4XG7A72936 compatible with?

A: The 4XG7A72936 is a processor option kit validated for the Lenovo ThinkSystem ST650 V2 tower server. It uses the LGA 4189 socket and is part of the 3rd Generation Intel Xeon Scalable (Ice Lake-SP) platform supported by that system.

Q: What is the processor model in the 4XG7A72936, and what are its core specs?

A: The processor is the Intel Xeon Platinum 8352Y — 32 cores, 64 threads, 2.2 GHz base frequency, 3.4 GHz max turbo boost, 48 MB L3 cache, and a 205W TDP. It uses Intel's 10nm process node and runs on the LGA 4189 socket.

Q: What is the TDP of the Intel Xeon Platinum 8352Y, and does the ST650 V2 support it?

A: The 8352Y carries a 205W TDP. The ThinkSystem ST650 V2 is designed to support high-TDP Xeon Scalable processors; however, you should verify your specific power supply and cooling configuration against Lenovo's system documentation before installing this processor option kit.

Q: What is the difference between the high-priority and low-priority cores on the 8352Y?

A: The Intel Xeon Platinum 8352Y features a split-core architecture: 12 high-priority cores run at 2.4 GHz and 20 efficiency (low-priority) cores run at 2.0 GHz. Workload schedulers that are priority-core-aware can route latency-sensitive tasks to the 2.4 GHz cluster while background and throughput workloads use the 2.0 GHz cores.

The 4XG7A72936 is one of those processor options that earns its place by solving a specific architectural problem: you need a single-socket ST650 V2 to carry a mixed workload — video analytics, application services, and VM overhead simultaneously — without the latency spikes that come from over-subscribing a lower-core-count chip. The Intel Xeon Platinum 8352Y's 32 cores at 2.2 GHz base with a 3.4 GHz peak turbo gives you a wide, steady compute floor with burst capability reserved for the moments that matter.

Technical Highlights:

• 32C / 64T at 2.2–3.4 GHz: For a Milestone XProtect or Genetec Security Center server running deep-learning analytics on 50+ camera streams, this core count allows the VMS analytics engine, recording services, and OS overhead to coexist without CPU queue saturation — something 16-core configurations start to struggle with at scale.
• Hybrid Priority Core Split (12 @ 2.4 GHz + 20 @ 2.0 GHz): If your VMS or hypervisor is priority-core-aware, you get a hardware-enforced latency tier at no extra cost. Route event correlation and alert processing to the high-priority cluster; background archival and log jobs land on the efficiency cores automatically.
• 48 MB L3 Cache: Large on-die cache shrinks DRAM round-trips for hot datasets. On a VMS server with active index tables and analytics model weights in working memory, this directly translates to lower per-frame processing latency at sustained camera counts.

Deployment Considerations:

• At 205W TDP, this processor requires a power supply and airflow configuration that matches the ST650 V2's validated thermal envelope for high-TDP CPUs. Confirm PSU wattage headroom and chassis airflow before installation — do not assume the base ST650 V2 config automatically supports the top-bin processor without reviewing Lenovo's system configuration guide.
• The LGA 4189 platform is generation-locked: this processor does not drop into 2nd Gen (Cascade Lake) or 4th Gen (Sapphire Rapids) boards. Verify your ST650 V2 firmware revision supports Ice Lake-SP processors before ordering — Lenovo's ServerProven tool is the authoritative reference.

For security integrators building a centralized VMS server that needs to scale past 64 camera channels with analytics enabled, the ST650 V2 configured with the 4XG7A72936 represents a practical single-socket ceiling before you are forced into dual-socket or multi-node architecture — a meaningful cost-avoidance decision at the design stage.
