Lenovo 4XG7A37923 Xeon Silver 4216 W/o FAN

Lenovo 4XG7A37923 Xeon Silver 4216 16-Core Server Processor

Overview

The Lenovo 4XG7A37923 is a 2nd Generation Intel Xeon Silver 4216 processor designed for Lenovo server and workstation platforms using the LGA 3647 (Socket P) socket. Running 16 cores and 32 threads at a base frequency of 2.1 GHz — with a boost up to 3.2 GHz — this processor targets compute-intensive server workloads where balanced core density and clock speed matter more than raw single-thread performance. At 100W TDP, it fits within the thermal envelope of most mainstream 2U rack servers without demanding extreme cooling infrastructure. Note that the 4XG7A37923 ships without a heatsink or fan — ensure your server chassis includes a compatible cooling solution before ordering.

Key Features

• 16 Cores / 32 Threads: Parallelism at this level means the processor handles multi-threaded application workloads — virtualization, containerized microservices, or video analytics inference — without the per-core licensing overhead that comes with higher-core-count Platinum SKUs. For environments running 8–20 VMs, this is a practical sweet spot.
• 2.1 GHz Base / 3.2 GHz Boost: The 1.1 GHz boost headroom means bursty, latency-sensitive workloads — database queries, event correlation, API gateways — get a meaningful clock speed lift without requiring the processor to sustain high frequencies across all 16 cores simultaneously. Sustained multi-core workloads will settle closer to base.
• 22 MB L3 Cache: The 22 MB last-level cache reduces main-memory round trips on working sets that fit within cache. For surveillance VMS platforms or analytics engines processing frame buffers and metadata lookups, this reduces latency on repeated access patterns.
• 14 nm Lithography / 100W TDP: The 14 nm process node delivers a 100W thermal envelope — manageable in standard 2U chassis with mid-range cooling. Compared to higher-TDP Gold or Platinum Xeons, you get more headroom in power-budgeted rack deployments, particularly relevant in edge server cabinets with limited cooling capacity.
• LGA 3647 (Socket P) — 2nd Gen Xeon Scalable Platform: Socket P is the standard for Lenovo ThinkSystem servers targeting the 2nd Gen Scalable family. If you're populating a dual-socket board, verify that both sockets use matched QPI/UPI ratios to avoid asymmetric NUMA performance penalties.
• UPI Bus / 64-bit Operating Mode: Ultra Path Interconnect provides the high-bandwidth, low-latency CPU-to-CPU and CPU-to-I/O fabric required for multi-socket configurations. All 64-bit operating system environments are supported — no legacy 32-bit constraints.
• No Cooler Included: This is an OEM-style processor option intended for servers that supply cooling through the chassis airflow and an included or separately sourced heatsink. Attempting to run this in an open-bench or passive configuration without a rated heatsink will trip thermal protection within seconds of load.

Integration & Compatibility

The 4XG7A37923 is a Lenovo-sourced option part targeting ThinkSystem servers with the LGA 3647 Socket P platform supporting 2nd Generation Intel Xeon Scalable processors. Verify platform compatibility against your specific ThinkSystem server's compatibility matrix before ordering — not all Socket P boards support both 1st and 2nd Gen Scalable SKUs without a BIOS update, and some Lenovo server models restrict which processor TDP tiers are supported based on chassis airflow ratings. This processor is intended as a component upgrade or build-out part for server and workstation platforms; it is not a standalone compute device. Confirm your chassis cooling solution is rated for at least 100W processor TDP before installation.

Frequently Asked Questions

Q: Does the Lenovo 4XG7A37923 include a heatsink or cooling fan?

A: No. The 4XG7A37923 ships without a heatsink or fan. You must source a compatible cooling solution separately or confirm your target server chassis provides adequate active cooling for a 100W TDP processor.

Q: Which server socket does the 4XG7A37923 use?

A: The 4XG7A37923 uses the LGA 3647 (Socket P) interface, which is the standard socket for 2nd Generation Intel Xeon Scalable processors on Lenovo ThinkSystem platforms.

Q: What is the boost clock speed of the Xeon Silver 4216 in the 4XG7A37923?

A: The processor boosts up to 3.2 GHz from a 2.1 GHz base, providing additional headroom for bursty, latency-sensitive workloads.

Q: How many cores and threads does the 4XG7A37923 support?

A: The Xeon Silver 4216 provides 16 physical cores with 32 threads via Intel Hyper-Threading, suitable for virtualized and multi-threaded server environments.

Q: Is the 4XG7A37923 compatible with 1st Generation Xeon Scalable server platforms?

A: No. The 4XG7A37923 is a 2nd Generation Intel Xeon Scalable processor. While it uses the same LGA 3647 socket, compatibility with 1st Gen platforms is not guaranteed and typically requires a BIOS update or may be entirely unsupported depending on the server model. Verify against your server's compatibility matrix before purchasing.

Q: What is the TDP of the 4XG7A37923, and does it require special power infrastructure?

A: The processor has a 100W Thermal Design Power rating. This is within the standard range for mainstream 2U rack server power supplies and does not require dedicated high-TDP power infrastructure, but chassis cooling must be rated accordingly.

Karl Wilson

The 4XG7A37923 is a Lenovo OEM option for the Xeon Silver 4216 — and the detail that catches people off guard most often is the missing cooler. This isn't a retail boxed processor; it's a server option part, meaning Lenovo expects it to be installed in a ThinkSystem chassis that provides its own directed airflow and heatsink. Plan for that before the processor arrives on site.

Technical Highlights:

• 16C/32T at 100W TDP: For surveillance VMS servers running concurrent stream decoding, motion indexing, and analytics inference across 32–64 camera channels, 32 threads at 100W is a viable core density. You're not burning 150W+ like the Gold tier, which matters in edge cabinets with shared PDU capacity.
• 3.2 GHz Boost: Single-threaded VMS operations — database writes, alarm correlation, UI rendering — benefit from the 3.2 GHz boost ceiling. The 1.1 GHz delta between base and boost is meaningful when workloads fluctuate between idle and burst rather than running all cores at sustained load.
• 22 MB L3 Cache: On a VMS platform processing RTSP streams and writing metadata simultaneously, the 22 MB L3 reduces memory bus contention. It won't eliminate the need for adequate DDR4 capacity, but it softens the latency impact of repeated small working-set accesses.

Deployment Considerations:

• Verify your ThinkSystem server model supports 2nd Gen Xeon Scalable and that your current BIOS revision is compatible with the 4216 before installation — some earlier ThinkSystem boards shipped with BIOS that only recognizes 1st Gen SKUs out of the box.
• The 100W TDP is listed as the processor's rated envelope, but under sustained all-core workloads the actual package power can approach that ceiling — confirm your chassis fan zone and heatsink TDP rating before commissioning in a thermally constrained edge rack.

This processor is a practical fit for a Lenovo ThinkSystem 2U server being repurposed or expanded as a mid-tier surveillance recording and analytics node — enough core density for a 32–64 channel VMS workload, manageable power draw for a shared rack, and a well-understood platform for IT teams already running Lenovo infrastructure.
