Lenovo 4XG7A72949 Intel Xeon Silver 4310T 10-Core Server Processor

Overview

The Lenovo 4XG7A72949 is a factory-new, tray-packaged Intel Xeon Silver 4310T processor engineered for Lenovo ThinkSystem servers such as the ST650 V2. Built on Intel's 3rd Generation Xeon Scalable architecture (Ice Lake, 10nm), it pairs a 10-core / 20-thread design with a 2.3 GHz base clock and a 3.4 GHz Turbo Boost ceiling — enough headroom to handle mixed enterprise workloads including virtualization, database services, and security platform back-ends without burning through your power budget. At 105W TDP and an LGA 4189 socket, 4XG7A72949 slots directly into single- or dual-socket Lenovo platforms that support the 3rd Gen Scalable family.

Key Features

• 10 Cores / 20 Threads (Intel Xeon Silver 4310T): Twenty logical threads give your hypervisor or containerized workloads enough concurrency to avoid CPU contention during peak hours — practical for deployments running VMS, access control, and analytics services on shared infrastructure without standing up additional nodes.
• 2.3 GHz Base / 3.4 GHz Boost: The 1.1 GHz burst window means latency-sensitive tasks — live video decoding, database queries, real-time alerting — get the clock speed they need on demand, then the processor steps back down to conserve power when loads ease. You get responsive performance without paying for it in watts around the clock.
• 105W Thermal Design Power: At 105W TDP, this processor fits within the thermal envelope of 1U/2U tower-to-rack server chassis that use standard LGA 4189 cooling solutions. Note that no cooler is included with this tray pack — verify your server chassis or heatsink kit covers the 4310T before ordering.
• 15 MB L3 Cache: The 15 MB last-level cache reduces main-memory round-trips for working datasets that fit in cache — relevant for in-memory analytics, caching layers, and real-time processing pipelines where latency spikes hurt application SLAs.
• 10.4 GT/s System Bus: The 10.4 GT/s UPI interconnect rate sustains high-bandwidth data movement between processor sockets and to PCIe-attached devices (NVMe arrays, network adapters, GPU accelerators), keeping throughput from becoming the bottleneck in I/O-intensive server configurations.
• 64-Bit Operating Mode, 10nm Lithography: The 10nm Ice Lake process node delivers improved instructions-per-clock over prior Xeon generations at equivalent power levels. 64-bit mode is standard for any modern enterprise OS or hypervisor stack — Linux, Windows Server, VMware ESXi, and Hyper-V all run natively.
• LGA 4189 Socket, 3rd Gen Xeon Scalable Platform: LGA 4189 is the standard socket for Ice Lake Xeon Scalable processors. If your server already runs a 3rd Gen Scalable CPU, this processor is a drop-in upgrade or spare — no platform change required. Verify BIOS revision compatibility with Lenovo's support matrix before swapping.
• Tray Package: Tray format means no retail packaging overhead — appropriate for data center builds and OEM integration where the processor ships directly into the chassis. No thermal compound or heatsink is bundled; plan your heatsink and thermal interface material separately.

Integration & Compatibility

The 4XG7A72949 is positioned for Lenovo ThinkSystem platforms that support the LGA 4189 socket and 3rd Generation Intel Xeon Scalable processors — including the ThinkSystem ST650 V2 tower server referenced in the product designation. Before installing, confirm the server's BIOS/UEFI firmware is at the minimum version required to recognize Ice Lake Xeon Scalable SKUs; Lenovo publishes per-model compatibility matrices through its support portal. For dual-socket configurations, both processors must be identical SKUs to avoid asymmetric topology issues. Memory compatibility follows the platform's DDR4 channel and DIMM population rules — the processor itself does not restrict memory capacity beyond what the platform's memory controller supports. This processor is not compatible with LGA 3647 (Skylake/Cascade Lake) or LGA 4677 (Sapphire Rapids) sockets.

Frequently Asked Questions

Q: What servers is the Lenovo 4XG7A72949 compatible with?

A: The 4XG7A72949 uses the LGA 4189 socket and is designed for Lenovo ThinkSystem servers supporting 3rd Generation Intel Xeon Scalable processors, including the ThinkSystem ST650 V2. Always verify BIOS firmware compatibility with Lenovo's support documentation before installing.

Q: Does the 4XG7A72949 include a heatsink or cooler?

A: No. This is a tray-packaged processor — no cooler is included. You will need a compatible heatsink or thermal solution for the LGA 4189 socket, sourced separately through your server chassis or a Lenovo-qualified heatsink kit.

Q: What is the TDP of the Xeon Silver 4310T in this kit?

A: The Intel Xeon Silver 4310T has a Thermal Design Power (TDP) of 105W. Plan your server chassis cooling capacity and power supply headroom accordingly, particularly in dense rack deployments.

Q: Can the 4XG7A72949 be used in a dual-socket server configuration?

A: Yes, provided the server platform supports dual-socket LGA 4189 configurations. Both sockets must be populated with identical processor SKUs for proper operation. Consult the Lenovo server platform documentation for dual-socket population requirements.

Q: Is the 4XG7A72949 compatible with LGA 3647 or LGA 4677 servers?

A: No. The 4XG7A72949 uses the LGA 4189 socket exclusively. It is not backward compatible with LGA 3647 (used by 1st/2nd Gen Xeon Scalable) or forward compatible with LGA 4677 (4th Gen Xeon Scalable / Sapphire Rapids) platforms.

Jerry Tildsen

When I look at the 4XG7A72949, what stands out immediately is the 105W TDP combined with the 3.4 GHz Turbo ceiling — that's a processor that can punch above its power class when workloads demand it, then dial back during idle periods. For a server platform like the ST650 V2, that thermal profile makes it a practical fit in edge deployments where cooling capacity is limited but you still need burst performance for video analytics or database-driven security platforms.

Technical Highlights:

• 10-Core / 20-Thread Design: Twenty logical threads let a single socket handle concurrent VMS recording, real-time analytics, and management services without CPU saturation — reducing the need for a second server node at smaller sites.
• 3.4 GHz Turbo Boost: The 1.1 GHz burst range above base clock means latency-sensitive operations — live stream decoding, alert processing, database lookups — get the headroom they need during spikes rather than queuing behind background tasks.
• 15 MB L3 Cache on LGA 4189: Fifteen megabytes of last-level cache on a 10nm die keeps frequently accessed working sets off main memory, which matters for in-memory analytics pipelines and real-time processing on surveillance back-ends where memory latency directly affects throughput.

Deployment Considerations:

• This is a tray-only SKU with no included cooler — confirm your ST650 V2 chassis ships with or already has a heatsink rated for the LGA 4189 socket and 105W TDP before you place the order. Missing this step means a delayed installation.
• If you're upgrading an existing server from a 1st or 2nd Gen Xeon Scalable platform, the socket change from LGA 3647 to LGA 4189 means this is a platform replacement, not a processor swap — factor in memory and chassis compatibility.

The 4XG7A72949 is a well-matched processor for edge security servers running VMS with concurrent analytics — specifically deployments where a single LGA 4189 socket needs to carry multi-stream video processing, access control middleware, and database services under a constrained power budget.
