Lenovo 4XG7A37988 Intel Xeon Silver 4210R 10-Core Server Processor

Overview

The Lenovo 4XG7A37988 is a factory-tray Intel Xeon Silver 4210R processor engineered specifically for Lenovo ThinkSystem SR530, SR570, and SR630 rack servers. Built on Intel's 2nd Generation Xeon Scalable (Cascade Lake) architecture at a 14 nm process node, it delivers 10 cores, 20 threads, and a base clock of 2.4 GHz with a Turbo Boost ceiling of 3.2 GHz — all within a 100 W TDP envelope. If you're expanding compute density in an existing ThinkSystem rack deployment or provisioning a mid-range server for virtualization, analytics, or surveillance back-end workloads, this is the CPU option to evaluate before stepping up to a Gold-tier processor you may not need.

Key Features

• 10 Cores / 20 Threads (Cascade Lake): Twenty concurrent hardware threads on a single socket means a VMware or Hyper-V host can run 10–20 lightweight VMs before you start contending for CPU time. For a VMS server running 32–64 IP camera streams, this headroom prevents decode bottlenecks during peak motion events.
• 2.4 GHz Base / 3.2 GHz Turbo Boost: The 800 MHz burst window is meaningful for latency-sensitive tasks — video analytics inference, database query spikes, and NVR indexing all benefit from sustained single-thread performance rather than raw core count alone.
• 100 W TDP: Staying at 100 W keeps this CPU inside the thermal budget of the SR530/SR570/SR630 chassis without requiring additional cooling infrastructure. At high server density (4–8U per rack), that 100 W ceiling versus a 125 W+ Gold-tier part translates directly to lower PDU draw and reduced HVAC load per rack.
• 13.75 MB L3 Cache: The cache bank is sized to hold working sets for concurrent database queries, AI inferencing buffers, and compressed video streams simultaneously — reducing trips to slower DRAM and keeping latency flat under mixed workloads.
• LGA 3647 (Socket P) — Dual-Socket Capable: The SR570 and SR630 support dual-socket configurations. A second 4XG7A37988 can be added later to double core count and memory channels without a chassis swap — a practical upgrade path if workloads grow.
• Up to 1 TB Maximum Memory: The processor's memory controller supports up to 1 TB of system RAM across six DDR4 memory channels. For in-memory analytics databases, large VMS archives held in RAM cache, or virtualization hosts with memory-intensive guest VMs, that ceiling provides substantial runway.
• 20 PCIe Lanes (Cascade Lake architecture): Adequate for NVMe storage controllers, 25GbE NICs, and GPU/FPGA accelerator cards simultaneously — no forced trade-offs between storage bandwidth and network I/O in a single-slot configuration.
• 64-Bit Operating Mode: Full 64-bit execution with Intel VT-x and VT-d support (standard on Cascade Lake Silver) enables hardware-assisted virtualization and direct device assignment to guest VMs — required for GPU passthrough in AI inference deployments.
• Tray Package (No Cooler Included): Supplied as a tray OEM unit matched to Lenovo's ThinkSystem thermal solution. The chassis-integrated cooling assembly in SR530/SR570/SR630 handles this CPU at 100 W — no third-party heatsink procurement required, but verify Lenovo's official compatibility matrix for your specific server revision before ordering.

Integration & Compatibility

The 4XG7A37988 is validated for installation in the Lenovo ThinkSystem SR530, SR570, and SR630. These are 1U (SR530/SR630) and 2U (SR570) rack servers designed for data center, enterprise branch, and server-room deployments. The LGA 3647 socket is platform-specific — this processor is not compatible with consumer or HEDT Intel platforms. Lenovo ThinkSystem firmware and BIOS must be at a revision that supports 2nd Gen Xeon Scalable; consult the Lenovo ThinkSystem server compatibility documentation for your specific chassis serial range before installation.

For environments running network video recorders on ThinkSystem hardware, the 10-core / 20-thread profile handles concurrent H.265 decode and motion analytics for mid-to-large camera deployments without saturating the CPU. Pair with adequate DDR4 ECC RAM and an appropriate network switch backplane for sustained throughput. If your workload is primarily storage-bound rather than compute-bound, review your server storage planning before sizing on processor tier alone — additional NVMe capacity may deliver more impact than a CPU upgrade in VMS scenarios.

Frequently Asked Questions

Q: Which Lenovo ThinkSystem servers are compatible with the 4XG7A37988?

A: The 4XG7A37988 is validated for the Lenovo ThinkSystem SR530, SR570, and SR630. It uses the LGA 3647 (Socket P) and is not compatible with other socket platforms.

Q: Does a heatsink or cooler come included with the 4XG7A37988?

A: No. This is a tray-packaged processor. The ThinkSystem SR530/SR570/SR630 chassis includes an integrated cooling assembly designed for 100 W CPUs, so no separate heatsink is required when installing in a supported server.

Q: Can I add a second 4XG7A37988 to an existing SR570 or SR630?

A: The SR570 and SR630 support dual-socket configurations using LGA 3647. A second unit can be added to scale core count and memory bandwidth — verify that your specific server revision and BIOS level support dual-socket population before installing.

Q: What is the maximum RAM this processor supports?

A: The Xeon Silver 4210R supports up to 1 TB of DDR4 ECC memory per socket across six memory channels. Actual capacity is also constrained by the number of DIMM slots in your specific server chassis.

Q: Is the 4XG7A37988 suitable for running a VMS or NVR workload?

A: Yes. The 10-core / 20-thread profile at 2.4–3.2 GHz handles concurrent H.265 decode, motion analytics, and VMS database operations for mid-to-large IP camera deployments. For very high channel counts (128+) or GPU-accelerated analytics, evaluate a higher-core-count Xeon Gold option.

Q: What processor generation and architecture is the 4XG7A37988?

A: It is a 2nd Generation Intel Xeon Scalable processor based on the Cascade Lake microarchitecture, manufactured at 14 nm, with an Intel ARK ID of 197098.

The 4XG7A37988 lands in a practical sweet spot for ThinkSystem deployments where a Xeon Gold's 125–150 W TDP would push the rack's power budget without delivering proportional gains. At 100 W with a 3.2 GHz Turbo ceiling and 20 threads, it covers the compute profile for most mid-scale enterprise server builds without requiring chassis or PDU upgrades.

Technical Highlights:

• 100 W TDP ceiling: Keeps thermal dissipation within the SR530/SR570/SR630 integrated cooling design — no aftermarket heatsink, no additional airflow provisioning required in a properly configured ThinkSystem rack unit.
• 2.4 GHz base / 3.2 GHz Turbo: The 800 MHz burst is sustained long enough to matter for analytics inference spikes and VMS indexing — workloads that hit hard for short windows rather than sustaining full-load continuously.
• 1 TB max memory support: Six DDR4 channels and a 1 TB ceiling give this CPU room to support memory-heavy virtualization stacks or large in-memory databases without hitting an artificial platform wall.

Deployment Considerations:

• This is a tray unit — no cooler ships with it. The SR530/SR570/SR630 chassis thermal solution handles 100 W CPUs natively, but confirm your server's BIOS revision supports 2nd Gen Xeon Scalable before installation to avoid a no-POST situation.
• For dual-socket SR570 or SR630 builds, both processors must be identical — mixing Silver and Gold tier or different stepping levels in the same chassis is not supported by Lenovo's validation matrix.

Best fit: a ThinkSystem SR630 deployed as a mid-scale VMS server running 48–96 H.265 camera streams with concurrent analytics, where the 10-core / 20-thread profile covers decode and event processing without stepping into Gold-tier power draw or licensing overhead.
