Lenovo 4XG7A37933 Xeon Silver 4210 W/o FAN

Lenovo 4XG7A37933 Xeon Silver 4210 10-Core Server Processor

Overview

The Lenovo 4XG7A37933 is a 2nd Generation Intel Xeon Silver 4210 processor designed for Lenovo server and workstation platforms. Based on Intel's Cascade Lake architecture at 14 nm, it delivers 10 cores and 20 threads at a 2.2 GHz base clock with a 3.2 GHz Turbo Boost ceiling — the right balance of multi-threaded throughput and per-core performance for workloads that span virtualization, video analytics back-end processing, and surveillance NVR platforms running compute-heavy codecs. Sold without a heatsink or fan, the 4XG7A37933 is intended for system integrators and IT architects who are populating or upgrading Lenovo ThinkSystem servers where a compatible cooling solution is already in place or separately sourced.

Key Features

• 10 Cores / 20 Threads: Twenty concurrent hardware threads let the platform run multiple demanding workloads simultaneously — for instance, a surveillance server transcoding multiple H.265 streams while also executing analytics inference jobs — without the thread contention that bottlenecks lower core-count SKUs.
• 2.2 GHz Base / 3.2 GHz Turbo Boost: The 1 GHz headroom between base and boost frequencies means lightly-threaded tasks (single-stream decode, management daemons, admin queries) accelerate automatically. Under sustained all-core load, the 2.2 GHz floor provides predictable, steady throughput for batch jobs like archival transcoding or overnight report generation.
• 85 W TDP: At 85 W, this processor sits in the mid-range power envelope for the Xeon Silver 4000 family. That matters for dense rack deployments where per-slot heat output directly constrains how many nodes fit in a chassis without tripping thermal thresholds on shared cooling infrastructure. Plan your power budget accordingly — this is not a low-power SKU.
• 14 MB Intel Smart Cache: The shared L3 cache reduces main-memory traffic for workloads with moderate working sets — particularly beneficial in VMS back-ends where frame-buffer data is repeatedly accessed across multiple codec threads rather than streaming linearly through DRAM.
• Up to 1 TB Addressable Memory: Supporting up to 1 TB of system RAM across the platform's memory channels, this processor accommodates memory-hungry deployments such as in-memory databases, large analytics models, or high-channel-count video management systems that cache index data in RAM for sub-second query response.
• LGA 3647 (Socket P) — Cascade Lake Platform: The LGA 3647 socket is the standard for Intel's Scalable Processor platform used across Lenovo ThinkSystem 1S and 2S servers. Verify socket and BIOS compatibility on your specific Lenovo server model before ordering — this processor is a Lenovo OEM part and is validated within Lenovo's compatibility matrix.
• 64-Bit / UPI Bus Architecture: The UPI (Ultra Path Interconnect) bus handles inter-socket communication in dual-socket configurations, maintaining coherent memory access across processors without the bandwidth bottlenecks that affect older QPI implementations — relevant if you're expanding to a two-socket Lenovo server for higher core density.

Integration and Compatibility

The 4XG7A37933 is a Lenovo-branded OEM processor for deployment in compatible Lenovo server platforms using the LGA 3647 socket. It is not a retail-boxed Intel part — it ships without a heatsink or fan, so an appropriate server cooling solution must be in place. Before installing, confirm compatibility against the Lenovo ServerProven list for your specific ThinkSystem chassis and BIOS revision, as microcode and thermal module support varies by platform generation. This processor supports the standard server and workstation feature set of the Cascade Lake generation, including Intel Turbo Boost Technology 2.0, Intel Hyper-Threading, and the full set of Intel Virtualization extensions (VT-x, VT-d) relevant to hypervisor deployments. For surveillance-focused deployments, pair this processor with a compatible network video recorder platform to handle high-channel H.265 decode workloads efficiently. Integrators evaluating server memory upgrades alongside this CPU should confirm the platform's memory speed support tier, as the 4210 supports DDR4 at platform-defined frequencies per the Lenovo server's memory configuration guide.

Frequently Asked Questions

Q: Does the Lenovo 4XG7A37933 include a heatsink or fan?

A: No. The 4XG7A37933 is sold without a fan or heatsink (W/O FAN). A compatible Lenovo-approved thermal module must be installed separately. Confirm the correct heatsink SKU for your specific ThinkSystem server chassis before ordering.

Q: What socket does the 4XG7A37933 use?

A: It uses the LGA 3647 (Socket P) — Intel's standard socket for the Xeon Scalable platform. Verify that your Lenovo server model lists this CPU in its compatibility or ServerProven matrix before purchasing.

Q: What is the TDP of the Xeon Silver 4210?

A: The Thermal Design Power is 85 W. Plan your chassis cooling and power delivery accordingly, particularly in high-density rack environments.

Q: How many cores and threads does the 4XG7A37933 support?

A: 10 physical cores and 20 threads via Intel Hyper-Threading, operating in 64-bit mode with a 2.2 GHz base frequency and 3.2 GHz Turbo Boost ceiling.

Q: What is the maximum RAM this processor supports?

A: Up to 1 TB of system memory is supported, subject to the memory slot count and configuration of the installed Lenovo server platform.

Q: Is the 4XG7A37933 compatible with dual-socket server configurations?

A: The Xeon Silver 4210 supports multi-socket configurations using the UPI bus. Whether dual-socket operation is available depends on your specific Lenovo server chassis and board design — consult the ServerProven compatibility list for your platform.

James Everett

The 4XG7A37933 is a pragmatic mid-range Xeon Silver pick for integrators building or expanding Lenovo ThinkSystem servers where the 85 W TDP ceiling and 10-core / 20-thread configuration hit the sweet spot between compute density and thermal manageability. I reach for this SKU specifically when a project needs sustained multi-threaded throughput — think a 64-channel VMS back-end running H.265 decode plus motion analytics — without pushing into the 105–125 W range that strains standard 1U thermal modules.

Technical Highlights:

• 10C/20T at 85 W: Twenty hardware threads at a controlled 85 W TDP means you can populate dual-socket Lenovo platforms and stay within standard rack PDU power budgets without dedicating a high-density cooling chassis to the deployment.
• 3.2 GHz Turbo Boost: The 1 GHz gap between base (2.2 GHz) and boost (3.2 GHz) delivers meaningful acceleration on latency-sensitive single-threaded admin and query workloads — useful when operators are pulling live footage or generating forensic reports from a running VMS without pre-scheduling the job.
• 14 MB Smart Cache + 1 TB Memory Ceiling: For surveillance deployments running in-memory index caches, the 14 MB L3 reduces DRAM pressure on hot frame-buffer data, while the 1 TB addressable memory ceiling leaves room to scale channel counts without a platform swap.

Deployment Considerations:

• This part ships without cooling — confirm your Lenovo ThinkSystem chassis has the correct performance heatsink kit on hand before the server goes into a rack. Installing at a remote site without the right heatsink on the shelf is a common delay point.
• The 4XG7A37933 is a Lenovo OEM SKU, not a retail-boxed Intel part. BIOS microcode support is tied to Lenovo's firmware release schedule — check that your server's BIOS revision supports Cascade Lake before deploying; some earlier ThinkSystem BIOS versions require an update prior to installation.

Best fit: a single- or dual-socket Lenovo ThinkSystem server acting as a dedicated VMS recording and analytics node in a 32–64 camera enterprise surveillance deployment, where sustained multi-threaded codec workloads need predictable throughput and the facility's power infrastructure sets a hard per-node wattage cap.
