Lenovo 4XG7A63460 Intel Xeon Gold 5318Y 24-Core Processor Option for ThinkSystem SR650 V2

Overview

The Lenovo 4XG7A63460 is a factory-configured processor option kit pairing the 3rd Generation Intel® Xeon® Gold 5318Y with the Lenovo ThinkSystem SR650 V2 platform. At 24 cores, 48 threads, and a 2.1 GHz base clock with 3.4 GHz boost, this CPU sits in the mainstream Xeon Gold 5000 tier — the right balance of core density and per-core performance for workloads that demand both parallel throughput and single-threaded responsiveness. If you're provisioning SR650 V2 nodes for video analytics, VMS backend processing, or virtualized network video recorder infrastructure, the 5318Y delivers enough core count to run concurrent workloads without pushing into the premium pricing of the 6000-series Xeon Platinum lineup.

Seated in the LGA 4189 socket on the SR650 V2, this processor draws 165W TDP — a figure that matters at the rack level when you're calculating PDU headroom and cooling requirements across a multi-node deployment.

Key Features

• 24 Cores / 48 Threads at 2.1 GHz Base: The 5318Y's 24-core layout handles high thread-count workloads without the cost premium of Platinum-tier silicon. For video analytics deployments running 64+ camera streams, parallel decode and inference threads distribute efficiently across available cores — you're not waiting on a bottlenecked pipeline.
• 3.4 GHz Boost Frequency: Single-threaded tasks that can't be parallelized — VMS database queries, event indexing, alarm rule evaluation — benefit from a 1.3 GHz boost headroom above base clock. The 5318Y reaches 3.4 GHz on high-priority cores when the workload demands it.
• Heterogeneous Core Architecture (8 HP + 16 LP Cores): Intel's hybrid core design assigns 8 high-priority cores at 2.3 GHz and 16 low-priority cores at 1.8 GHz within the same die. In practice, latency-sensitive processes get scheduled to the HP cores automatically under supported OS schedulers, reducing contention on shared datacenter server infrastructure.
• 36 MB Last-Level Cache: A 36 MB L3 cache keeps frequently accessed data — motion detection buffers, VMS index tables, active VM pages — closer to the execution units. Compared to smaller cache configurations, this reduces main-memory round-trips on sustained random-access workloads common in multi-tenant security server environments.
• 48 Threads via Hyper-Threading: Virtualization hosts running mixed workloads (VMS engine + analytics container + NVR storage daemon on the same node) benefit directly from thread density. 48 logical processors give the hypervisor scheduler more granular allocation options without requiring a dual-socket configuration.
• 11.2 GT/s System Bus Rate: The 11.2 GT/s UPI interconnect rate keeps memory bandwidth and inter-socket communication latency predictable under sustained load — relevant when the SR650 V2 is configured with high-density DIMM populations for in-memory video caching or when running dual-socket builds.
• 10 nm Intel Ice Lake Lithography: The 10 nm process node delivers improved instructions-per-cycle efficiency over prior-generation 14 nm Cascade Lake processors. For always-on server workloads like 24/7 video recording, the efficiency gain translates to lower per-core power consumption relative to raw clock speed — meaningful over a multi-year operational lifespan.
• 64-Bit Operating Mode / LGA 4189 Socket: Native 64-bit execution and the LGA 4189 form factor confirm full compatibility with the SR650 V2 motherboard. This is a Lenovo-sourced option kit, not an aftermarket upgrade — it installs into the supported processor socket with manufacturer-validated firmware and thermal interface support.

Integration and Compatibility

The 4XG7A63460 is specifically validated for the Lenovo ThinkSystem SR650 V2 server platform. LGA 4189 is the socket standard for 3rd Generation Intel Xeon Scalable processors; it is not backward compatible with LGA 3647 (used in 1st/2nd Gen Xeon Scalable platforms). Verify your SR650 V2 board revision and current UEFI firmware version against Lenovo's compatibility matrix before installing — Lenovo publishes processor compatibility by machine type and firmware level through its support portal.

For deployments pairing compute with IP camera ecosystems running analytics at the edge, the SR650 V2 with a 5318Y handles central VMS aggregation, deep-learning inference offload (with appropriate GPU or FPGA accelerator add-in cards), and storage I/O management simultaneously. The 165W TDP fits within the SR650 V2's thermal envelope with standard cooling configurations; confirm rack cooling capacity — especially in dense multi-node bays — against your facility's BTU ratings.

This processor option ships as a Lenovo-sourced component intended for integration into supported SR650 V2 configurations.

Ted Perry

The Lenovo 4XG7A63460 is one of those processor option kits that hits the right spot for security infrastructure deployments — 24 cores and 48 threads at a 165W TDP puts you solidly in the workload-efficient tier of Xeon Gold without paying for Platinum headroom you won't use on a VMS aggregation node or analytics server. I've scoped this part into SR650 V2 builds where the requirement was concurrent multi-stream video decode plus containerized analytics, and the 5318Y handles that mix without the thermal ceiling issues you run into with higher-TDP 6000-series configs in constrained rack environments.

Technical Highlights:

• 36 MB L3 Cache: Keeps VMS index tables and active stream buffers closer to compute — reduces main-memory latency on random-access patterns typical of multi-camera recording workloads where you're constantly seeking across a large active dataset.
• 3.4 GHz Boost / 2.1 GHz Base: The 1.3 GHz burst headroom matters for event-driven alarm processing and database queries that can't be parallelized. The SR650 V2's power management governor will push the 5318Y to 3.4 GHz on latency-sensitive threads while the remaining cores handle background I/O at lower frequency — efficient use of the 165W budget.
• 8 High-Priority Cores at 2.3 GHz: The heterogeneous core layout (8 HP + 16 LP) gives the OS scheduler a structural hint for priority-sensitive processes. Under a properly configured Linux or Windows Server deployment, latency-critical VMS services land on HP cores without manual CPU affinity pinning.

Deployment Considerations:

• LGA 4189 is generation-locked — this processor does not install in SR650 (original) or any LGA 3647 platform. Confirm machine type and UEFI firmware revision from Lenovo's compatibility matrix before the part ships; a firmware mismatch can prevent POST on an otherwise correct hardware pairing.
• At 165W TDP per socket, a dual-socket SR650 V2 configuration draws 330W at the processor level alone before memory, storage, and NIC loads. Size your UPS and PDU circuits with full node draw in mind, not just CPU TDP — this is where datacenter builds routinely underestimate circuit capacity.

For a centralized video management server build — particularly a VMS aggregation node running 100+ camera streams with parallel analytics offload — the SR650 V2 with the 4XG7A63460 is a well-matched foundation at the Xeon Gold tier, avoiding overprovisioning cost while keeping enough core density and cache to sustain 24/7 multi-stream workloads without thermal throttling.
