Lenovo 4XG7A83808 SR630 V3 Gold 5420+ 28C 205W 2.0GHZ

Lenovo 4XG7A83808 Intel Xeon Gold 5420+ 28-Core Processor for ThinkSystem SR630 V3

Overview

The Lenovo 4XG7A83808 is a factory-configured processor option for the ThinkSystem SR630 V3, pairing the Intel Xeon Gold 5420+ with 28 cores, 56 threads, and a 205W thermal envelope. At a 2.0 GHz base clock with a 4.1 GHz boost and a 52.2 MB L3 cache, this 4th Generation Intel Xeon Scalable processor is aimed at compute-dense workloads — video analytics servers, edge AI inference platforms, and high-throughput enterprise applications where parallel thread count and clock headroom both matter. If you're sizing a server for a multi-channel Milestone XProtect or Genetec deployment handling real-time analytics across dozens of streams, the 28-core / 56-thread configuration gives you the parallelism to handle that without over-provisioning into a higher-tier socket.

This processor installs into the Lenovo ThinkSystem SR630 V3 via the LGA 4677 (Socket E) interface — the same platform used across the broader 4th Gen Intel Xeon Scalable processor lineup, so your SR630 V3 chassis investment carries across processor upgrades without a platform change.

Key Features

• 28 Cores / 56 Threads: More cores mean more parallel workloads handled without context-switch overhead. For video management software servers running simultaneous analytics on high-resolution streams, 56 logical threads let the OS schedule compute tasks efficiently without one process starving another.
• 2.0 GHz Base / 4.1 GHz Boost (Intel Turbo Boost): The 2.0 GHz base keeps steady-state power consumption predictable, while the 4.1 GHz boost handles burst workloads — relevant when a VMS triggers simultaneous motion-event processing across multiple camera groups.
• Hybrid Core Architecture — 8 High-Priority Cores at 2.2 GHz + 20 Efficiency Cores: Intel's performance hybrid on the Xeon Gold 5420+ dedicates 8 cores to latency-sensitive tasks and assigns background processes to the remaining 20. For a security analytics server, this means real-time alarm processing gets priority over housekeeping tasks like database indexing or log archiving.
• 52.2 MB L3 Cache: A large on-die cache reduces memory latency for frequently accessed data structures — meaningful in inference workloads where model weights or frame buffers repeatedly cycle through the processor. Less DRAM round-trip means lower per-frame inference latency.
• 16 GT/s System Bus Rate: The 16 GT/s interconnect (Intel UPI) sustains high-bandwidth communication between processor and I/O subsystem. In NVR or analytics server deployments, this matters for sustained PCIe throughput to GPU accelerators or high-speed NVMe storage arrays.
• 64-Bit Operating Mode: Full 64-bit support is table stakes for any modern server OS (Windows Server, RHEL, Ubuntu Server), but worth confirming explicitly for enterprise procurement documentation.
• 205W TDP — Plan Your Cooling Budget: At 205W, this processor runs at the upper boundary of standard 1U/2U server thermal design. The SR630 V3 is engineered to handle this TDP, but note that no cooler is included with the 4XG7A83808 — the SR630 V3 chassis provides integrated cooling. Do not order this as a standalone processor upgrade without verifying SR630 V3 thermal compatibility with your specific chassis configuration and ambient environment.
• LGA 4677 (Socket E) Platform: The 4th Gen Xeon Scalable platform on Socket E supports DDR5 memory and PCIe Gen 5 I/O. This is the forward path for Lenovo's enterprise server line — meaning accessory upgrades (memory DIMMs, PCIe accelerators) made today remain compatible with future processor refreshes on the same socket.

Integration and Compatibility

The 4XG7A83808 is a ThinkSystem SR630 V3-specific option. It is not a retail-boxed processor — it ships as a Lenovo-configured component intended for integration into the SR630 V3 platform. Before ordering, confirm your SR630 V3 chassis model and UEFI firmware revision support the Intel Xeon Gold 5420+; Lenovo publishes a compatibility matrix for SR630 V3 processor options that should be your authoritative reference. For multi-processor (dual-socket) SR630 V3 configurations, both sockets must be populated with identical processor models — mixing Xeon Gold tiers within the same chassis is not supported on this platform.

For environments deploying this server as part of a network video recorder or centralized analytics node, pair the SR630 V3 with appropriate DDR5 ECC RDIMMs and, if running GPU-accelerated inference, verify PCIe Gen 5 slot availability in your SR630 V3 chassis configuration before specifying GPU accelerator cards.

Q: Can I install two 4XG7A83808 processors in a dual-socket SR630 V3?

A: Dual-socket SR630 V3 configurations require identical processor models in both sockets. Two 4XG7A83808 units (both Xeon Gold 5420+) can be configured in a dual-socket SR630 V3, but verify your specific SR630 V3 chassis supports dual-socket operation before ordering.

Q: What is the processor's boost frequency and how many cores reach it?

A: The Intel Xeon Gold 5420+ boosts up to 4.1 GHz under Intel Turbo Boost. The processor includes 8 high-priority cores with a base frequency of 2.2 GHz and 20 efficiency cores. The 4.1 GHz boost applies under appropriate thermal and power headroom conditions.

Q: Is the 4XG7A83808 suitable for AI inference or GPU-accelerated video analytics workloads?

A: The 28-core / 56-thread configuration and 16 GT/s system bus rate make it a capable host processor for GPU-accelerated inference servers. The SR630 V3's PCIe Gen 5 support (via the LGA 4677 platform) provides the I/O bandwidth needed for high-throughput GPU accelerator cards. Verify GPU slot availability and power delivery in your specific SR630 V3 configuration.

Jerry Tildsen

When I spec a server for a large-scale video analytics deployment, the 4XG7A83808 sits in an interesting position: 28 cores and 56 threads at a 205W TDP gives you serious parallel compute without climbing into the Xeon Platinum bracket. That 52.2 MB L3 cache is the spec I pay attention to most — inference pipelines that repeatedly pull model weights benefit directly from reduced DRAM round-trips, and on a multi-stream VMS server handling 64+ channels, that latency difference compounds.

Technical Highlights:

• Hybrid Core Design (8 High-Priority + 20 Efficiency Cores): The 8 performance cores clocked at 2.2 GHz base handle latency-sensitive tasks; the 20 efficiency cores absorb background load. In a Genetec or Milestone deployment, this maps well to separating real-time event processing from scheduled database maintenance.
• 4.1 GHz Boost Frequency: Sustained burst performance up to 4.1 GHz means the server can spike compute for alarm correlation or batch analytics without requiring a higher-TDP processor class — keeping the power budget predictable for data center rack planning.
• 16 GT/s UPI System Bus: High interconnect bandwidth sustains throughput to PCIe Gen 5 devices — relevant when you're pairing the SR630 V3 with an NVIDIA A2 or similar inference-class GPU and need the host bus to keep pace with the accelerator's data appetite.

Deployment Considerations:

• No cooler ships with the 4XG7A83808 — this is expected for a platform-integrated processor, but verify your SR630 V3 chassis airflow configuration (standard vs. high-performance fan modules) is rated for a 205W TDP processor before finalizing the order.
• Dual-socket builds require two identical units; mixing processor models in a dual-socket SR630 V3 is not supported, so if you're budgeting a phased deployment (one socket now, second socket later), plan the second processor purchase at the same time to avoid SKU availability risk.

This processor makes the most sense in a centralized analytics server role — think a 64-channel or larger Milestone XProtect Corporate or Genetec Security Center deployment where the server is handling both stream management and edge AI inferencing, and where you need the 28-core headroom to avoid contention between the VMS process scheduler and the inference engine.
