Lenovo 4XG7A63580 ThinkSystem SR650 V2 Intel Xeon Platinum 8352S Processor Kit

Overview

The Lenovo 4XG7A63580 is a factory-new Intel Xeon Platinum 8352S processor option kit engineered specifically for the ThinkSystem SR650 V2 rack server. The 8352S is a 32-core, 64-thread 3rd Generation Intel Xeon Scalable processor running at a 2.2 GHz base clock with a 3.4 GHz boost — designed for data center workloads that demand sustained multi-threaded throughput without throttling under continuous load. At 205W TDP, this is a high-performance tier part: plan your thermal and power budget accordingly before committing.

This kit targets enterprises expanding compute density in ThinkSystem SR650 V2 chassis, adding processing headroom for virtualization stacks, AI inference pipelines, database consolidation, or high-core-count simulation workloads. Lenovo processor option kits ship as factory-genuine components verified for the specific server platform — no guesswork on socket compatibility or firmware support.

Key Features

• 32 Cores / 64 Threads at 2.2 GHz Base, 3.4 GHz Boost: The 8352S delivers 64 logical processors to your hypervisor, allowing dense VM packing without contention. A 3.4 GHz Turbo ceiling means latency-sensitive workloads — database query threads, real-time analytics — still get meaningful single-thread headroom when the scheduler demands it.
• Hybrid Core Allocation (12 High-Priority @ 2.4 GHz + 20 Standard @ 2.0 GHz): Intel's Speed Select Technology partitions 12 cores at 2.4 GHz for priority workloads while the remaining 20 cores sustain 2.0 GHz base throughput. In practice this means you can pin latency-critical application threads to the high-priority ring without giving up total core count across the socket.
• 48 MB L3 Cache: 48 MB of last-level cache across 32 cores reduces DRAM access latency for working-set-heavy workloads. Database engines, VMS video analytics servers, and in-memory key-value stores all benefit from a larger L3 — fewer round-trips to DRAM means more consistent frame-rate or query throughput under load.
• 10 nm Ice Lake Architecture, LGA 4189 Socket: Third-generation Xeon Scalable (Ice Lake-SP) on the LGA 4189 platform delivers AVX-512 VNNI instruction support — directly relevant if the SR650 V2 is running AI inference workloads or deep learning video analytics. The 10 nm node also improves IPC over the prior generation, so you get more compute per watt than equivalent-TDP Cascade Lake parts.
• 11.2 GT/s UPI Bus: Ultra Path Interconnect at 11.2 GT/s sustains high-bandwidth inter-socket communication in dual-processor SR650 V2 configurations. If you are running a two-socket build, this bus rate is what keeps NUMA latency manageable when threads cross socket boundaries — relevant for large in-memory datasets that don't fit in a single socket's memory domain.
• 205W TDP: At 205W, this processor sits at the upper thermal envelope for the SR650 V2 platform. Verify your chassis airflow configuration and power supply headroom before deploying — pairing two of these in a dual-socket build draws over 400W in CPU alone before memory and storage loads are factored in.
• 64-Bit Operating Modes: Full 64-bit execution support is expected at this tier, but confirms compatibility with enterprise Linux distributions, Windows Server, and VMware ESXi without legacy mode constraints. No 32-bit OS limitations to work around in a modern virtualization stack.

Integration and Compatibility

The 4XG7A63580 is a Lenovo-qualified option kit for the ThinkSystem SR650 V2, meaning Lenovo's firmware and hardware compatibility matrix covers this combination. The LGA 4189 socket (also called Whitley platform) is exclusive to 3rd Generation Intel Xeon Scalable processors — do not attempt to install this in SR650 V1 chassis, which use LGA 3647 (Purley platform). Verify the SR650 V2 system board stepping and UEFI firmware revision against Lenovo's ServerProven compatibility list before procurement if the chassis is already deployed in production. For Lenovo ThinkSystem servers, Lenovo option kits are the correct path when you need platform-validated components with matching firmware support. Enterprises building out data center compute infrastructure will also want to review memory configuration guides — the 8352S supports up to 8-channel DDR4 per socket, and memory population order directly impacts achieved bandwidth. For AI-compute or video management server deployments, pairing this processor with the appropriate NVMe storage and GPU accelerator configuration completes the compute node. If your workload is primarily network-intensive, consider reviewing your network switching infrastructure alongside processor upgrades to avoid creating a new bottleneck at the NIC or top-of-rack switch.

Frequently Asked Questions

Q: Is the Lenovo 4XG7A63580 compatible with the ThinkSystem SR650 V1?

A: No. The 4XG7A63580 uses the LGA 4189 socket (Whitley platform) and is qualified exclusively for the ThinkSystem SR650 V2. The SR650 V1 uses the LGA 3647 (Purley) socket and is not compatible with 3rd Generation Xeon Scalable processors.

Q: What is the thermal design power (TDP) of the 4XG7A63580 processor?

A: The Intel Xeon Platinum 8352S in this kit has a 205W TDP. Ensure your SR650 V2 chassis cooling configuration and power supply capacity can support this thermal load, especially in dual-processor builds.

Q: Does the 8352S processor support AVX-512 instructions?

A: Yes. As a 3rd Generation Intel Xeon Scalable (Ice Lake-SP) processor, the 8352S supports AVX-512 including VNNI extensions, which are relevant for AI inference, deep learning video analytics, and scientific compute workloads.

Q: What is the maximum Turbo Boost frequency for the 4XG7A63580?

A: The Intel Xeon Platinum 8352S boosts up to 3.4 GHz. It also features a high-priority core designation: 12 cores run at 2.4 GHz base (high-priority ring) while the remaining 20 cores run at 2.0 GHz, allowing workload-aware core allocation via Intel Speed Select Technology.

Q: What processor generation is the Lenovo 4XG7A63580?

A: It is a 3rd Generation Intel Xeon Scalable processor (code name Ice Lake-SP), manufactured on Intel's 10 nm process node. The specific model is the Intel Xeon Platinum 8352S in the Platinum 8000 series.

Q: How many cores and threads does the 4XG7A63580 provide?

A: The 8352S delivers 32 physical cores and 64 threads (with Hyper-Threading enabled). The 48 MB L3 cache is shared across all 32 cores.

Marty Allison

The 4XG7A63580 is one of those parts where the headline core count tells only half the story. The 8352S ships with Intel Speed Select Technology baked in — 12 of the 32 cores are binned as high-priority and run a 2.4 GHz base instead of the standard 2.0 GHz. In a ThinkSystem SR650 V2 running a mixed workload, that means you can dedicate the fast-ring cores to latency-sensitive processes (say, a VMS analytics engine or a transactional database) while the remaining 20 cores handle batch or background jobs — all within a single 205W socket, without partitioning across physical nodes.

Technical Highlights:

• 3.4 GHz Turbo Boost: Even at 32 cores, the 8352S sustains 3.4 GHz on active threads under Turbo — meaningful when your workload scheduler concentrates load on a subset of cores rather than spreading evenly across all 64 threads.
• 48 MB L3 Cache across 32 Cores: 1.5 MB per core of last-level cache is above the average for this core count tier. In-memory databases, video analytics inference caches, and high-connection-count network appliances all hold larger working sets without thrashing DRAM, which shows up directly as lower 99th-percentile latency.
• 11.2 GT/s UPI in Dual-Socket SR650 V2: If you populate both CPU sockets on the SR650 V2, the 11.2 GT/s UPI interconnect keeps cross-NUMA bandwidth high enough that most enterprise applications won't see a sharp NUMA penalty — this matters for workloads that allocate memory across both sockets during initialization.

Deployment Considerations:

• At 205W TDP per socket, a fully-loaded dual-processor SR650 V2 will pull well over 500W at the server level under sustained load. Size your PDU circuits and UPS runtime calculations against that number, not a chassis idle figure — I've seen power budget miscalculations stall deployments at the rack level.
• The LGA 4189 platform is Whitley only — triple-check that the SR650 V2 UEFI is updated to a firmware revision that explicitly lists 8352S support before installing. Lenovo's ServerProven tool is the authoritative reference; don't rely on socket compatibility alone to infer firmware readiness.

This processor option kit is the right call for an SR650 V2 build anchored around a high-density virtualization host or a physical AI inference node where AVX-512 VNNI acceleration is a hard requirement — not for a general-purpose workload server where a lower-TDP 24-core part would deliver similar throughput at 40W less per socket.
