Lenovo 4XG7A63403 SR630 V2 Gold 5320 26C 185W 2.2GHZ

Lenovo 4XG7A63403 Intel Xeon Gold 5320 26-Core Processor for ThinkSystem SR630 V2

Overview

The Lenovo 4XG7A63403 is an Intel Xeon Gold 5320 processor option for the ThinkSystem SR630 V2 server platform — a 3rd Generation Intel Xeon Scalable CPU running at 2.2 GHz base with 26 cores, 52 threads, and a 185W TDP. If you're provisioning SR630 V2 nodes for compute-intensive workloads like video analytics processing, VMS back-end hosting, or enterprise surveillance data pipelines, this processor kit slots directly into the LGA 4189 socket and delivers meaningful per-core throughput without pushing into the top-tier power envelope of higher-bin SKUs.

This is a component-level part, not a complete server — the 4XG7A63403 is the Lenovo-qualified processor option specific to the SR630 V2 platform. Sourcing the Lenovo-branded kit ensures compatibility validation against Lenovo's firmware and system thermal profiles for that chassis.

Key Features

• 26 Cores / 52 Threads (Intel Xeon Gold 5320): 52 logical processors visible to the OS means workloads like multi-stream video decoding, parallel analytics inference, or high-thread-count database operations don't bottleneck waiting for CPU cycles. On a dual-socket SR630 V2, you're looking at 104 logical processors per node.
• 2.2 GHz Base / 3.4 GHz Boost: The 1.2 GHz boost headroom matters for bursty workloads — event-triggered analytics or alarm processing that demands peak single-thread response. Sustained multi-threaded loads (bulk encoding, large-batch ingestion) run at base, so plan capacity against 2.2 GHz, not 3.4 GHz, for sustained pipeline throughput.
• Heterogeneous Core Architecture — 12 High-Priority + 14 Efficiency Cores: The 5320 splits its 26 cores into 12 high-priority cores running at 2.5 GHz and 14 lower-priority cores at 2.0 GHz. Workload schedulers that are NUMA- and priority-aware will naturally route latency-sensitive threads to the high-priority cluster, leaving the 14-core cluster for background tasks like indexing, replication, or log processing.
• 39 MB L3 Cache: A large on-die cache reduces main-memory fetches on data-intensive operations. For NVR or VMS applications repeatedly accessing the same metadata index or codec state tables, this cache depth directly reduces latency variance under load.
• 52 Threads via Hyper-Threading: Full HT support doubles the logical thread count, which benefits virtualised server deployments where multiple VMs share the same physical host — each VM sees more schedulable threads without additional physical cores.
• 185W TDP: At 185W, this is a mid-range power draw for a 26-core Gold SKU. The SR630 V2 is engineered around this TDP class, so cooling and power delivery infrastructure already accounts for it. If you're building a dense rack with multiple SR630 V2 nodes, 185W per socket is a known, plannable figure for PDU and cooling capacity design.
• LGA 4189 Socket, 10nm Lithography: The 10nm process node improves instructions-per-clock efficiency relative to prior-generation 14nm Xeon parts, which translates to better performance per watt — relevant when comparing against older Xeon SP platforms still in the field.
• 11.2 GT/s System Bus: The UPI (Ultra Path Interconnect) bus rate governs inter-socket bandwidth in dual-processor configurations. At 11.2 GT/s, cross-socket memory access and inter-processor communication don't become a bottleneck in tightly-coupled multi-socket workloads.
• 64-bit Operating Mode: Full 64-bit support is a baseline requirement for any modern server OS and hypervisor — relevant to note for compliance checklists and procurement documentation.

Integration and Compatibility

The 4XG7A63403 is a Lenovo-qualified option kit designed specifically for the ThinkSystem SR630 V2 platform. Deployment in any other chassis — including non-SR630 systems or older SR630 V1 units — is outside Lenovo's validated configuration and may result in firmware incompatibility or thermal management issues. Always verify against the Lenovo ServerProven compatibility matrix for the specific SR630 V2 machine type before ordering a second unit or pairing with third-party memory and PCIe expansion cards.

For server and storage infrastructure build-outs supporting enterprise surveillance or physical security platforms, this processor tier pairs well with high-memory-bandwidth DIMMs to keep up with multi-stream video decode.

The 4XG7A63403 is a purpose-specific processor kit — and that specificity matters. The Intel Xeon Gold 5320 at 185W TDP is a deliberate mid-point in the SR630 V2 processor lineup: 26 cores and 52 threads give you real multi-workload headroom, but you're not paying the power and cost premium of the higher-bin 5000-series parts. For teams building out SR630 V2 nodes as dedicated VMS compute hosts or analytics processing back-ends, this is the core-count-to-TDP ratio worth evaluating first.

Technical Highlights:

• Heterogeneous Core Cluster (12 @ 2.5 GHz + 14 @ 2.0 GHz): Workload schedulers that respect priority assignments will route real-time analytics and alarm handling to the 12 high-priority cores, keeping latency tight on time-sensitive tasks while the 14-core cluster handles background ingestion and indexing.
• 3.4 GHz Boost Frequency: The 1.2 GHz boost headroom is genuinely useful for event-driven burst processing — short-duration peaks from motion detection cascades or concurrent alert evaluations — but sustained encode/decode pipelines will run at the 2.2 GHz base. Size your channel capacity math against 2.2 GHz.
• 39 MB L3 Cache + 11.2 GT/s UPI: In dual-socket SR630 V2 configurations, the 11.2 GT/s inter-processor bus keeps cross-socket memory traffic from becoming a ceiling. The 39 MB cache reduces round-trips to DRAM on repeated hot-data access patterns common in database-backed VMS deployments.

Deployment Considerations:

• This processor must be paired with an SR630 V2 chassis — not SR630 V1, not a third-party LGA 4189 board. Lenovo's firmware and thermal management are validated as a system; mixing chassis generations voids that validation and may produce unpredictable boost behavior under sustained load.
• At 185W, dual-socket SR630 V2 nodes draw up to 370W in processor power alone under full load. Factor this into per-rack PDU capacity and UPS sizing before finalising a dense deployment — it's a figure that catches teams used to lower-TDP Xeon-D or Bronze-tier builds.

This processor tier makes the most sense in dedicated VMS application server builds — specifically SR630 V2 nodes running Milestone XProtect, Genetec Security Center, or similar multi-server VMS architectures where the Management Server or Recording Server role needs 50+ logical processors to handle concurrent stream processing, metadata indexing, and client session management without resource contention.
