Lenovo 4XG7A07254 SR570 Xeon 4114T 10C/85W/2.2GHZ

Lenovo 4XG7A07254 Xeon Silver 4114T 10-Core Server Processor

Overview

The Lenovo 4XG7A07254 is the Intel Xeon Silver 4114T processor option for the ThinkSystem SR570 rack server — a 10-core, 2.2GHz Skylake-generation CPU rated at 85W TDP. If you're speccing a mid-density compute node where power efficiency matters as much as core count, the 4114T's 85W envelope makes it a practical choice for high-density rack builds where per-slot thermal headroom is constrained. This is a component-level part: it ships as a processor upgrade or base configuration for the SR570 platform, not a standalone server.

Key Features

• 10 Cores / 20 Threads at 2.2GHz Base: The 4114T delivers 20 logical processors under workloads that benefit from hyper-threading — suitable for multi-threaded server applications, virtualization hosts, or data analytics tasks where thread count drives throughput. Base clock at 2.2GHz is conservative enough to stay within the 85W TDP under sustained load.
• 3.0GHz Turbo Boost: Single-threaded or lightly threaded tasks can burst to 3.0GHz, giving snappier response for database queries, management operations, or jobs that serialize across one or two cores. The 800MHz headroom between base and turbo is meaningful for mixed workloads.
• 85W Thermal Design Power: At 85W TDP, this processor fits comfortably within standard 1U/2U rack cooling budgets. Lower than the 105W variants in the same family — a real factor if you're operating at high rack density where per-server BTU limits are enforced by the facility's CRAC design.
• 13.8MB L3 Cache: The 13.8MB shared L3 cache keeps frequently accessed data sets close to the cores, reducing main memory latency on cache-friendly workloads like in-memory databases, caching layers, or video analytics engines running on the SR570.
• 768GB DDR4 Maximum Memory: The 4114T supports up to 768GB of DDR4-SDRAM across the SR570's memory channels — enough headroom to run large in-memory datasets or heavily memory-mapped virtual machine configurations without hitting a ceiling on the CPU side. Actual installed maximum depends on the SR570's DIMM slot count and configuration.
• LGA 3647 (Socket P) — 1st Gen Intel Xeon Scalable: The LGA 3647 socket is the standard for Skylake-SP Xeon Scalable platforms. This processor is platform-locked to SR570 and compatible systems using Socket P — it is not interchangeable with later Ice Lake or Sapphire Rapids platforms, which moved to different sockets.
• 14nm Skylake Lithography: Manufactured on Intel's 14nm Skylake process, the 4114T is a proven, stable microarchitecture with well-understood firmware and BIOS support across Lenovo's SR570 platform. No first-generation silicon surprises — this generation's errata and microcode updates are mature.
• UPI Bus Interconnect: The Ultra Path Interconnect (UPI) bus handles inter-socket communication in dual-processor SR570 configurations. If you're building a two-socket SR570 for higher aggregate core count or memory capacity, UPI provides the low-latency coherency fabric between both 4114T CPUs.
• 64-Bit Operating Mode: Supports full 64-bit operation, compatible with all mainstream enterprise server operating systems — Windows Server, RHEL, SUSE, Ubuntu Server, VMware ESXi — running on Lenovo's ThinkSystem server line.

Integration and Compatibility

The 4XG7A07254 is a Lenovo option part designed specifically for the ThinkSystem SR570 server platform. Compatibility outside the SR570 depends on whether the target system uses the same LGA 3647 socket and supports 1st Generation Intel Xeon Scalable (Skylake-SP) processors — verify against Lenovo's compatibility matrix or the target platform's CPU support list before ordering. This part is sourced through the datacenter server components channel and is intended as a factory-configured or field-upgrade component within the SR570 ecosystem.

For environments building out a complete compute infrastructure, pair the SR570 with appropriate network switching and server storage to complete the platform. If your application is video analytics or physical security computing, review whether the SR570's memory bandwidth and core count align with your NVR or video management system workload profile before committing to this processor tier.

Frequently Asked Questions

Q: Is the Lenovo 4XG7A07254 a standalone processor or part of a complete server?

A: The 4XG7A07254 is a processor component — the Intel Xeon Silver 4114T — configured as an option part for the Lenovo ThinkSystem SR570 server. It is not a complete server. It ships as either a base or upgrade CPU for SR570 configurations.

Q: What socket does the 4XG7A07254 use, and can it be installed in other servers?

A: It uses the LGA 3647 (Socket P) socket, which is standard for 1st Generation Intel Xeon Scalable (Skylake-SP) platforms. Compatibility outside the SR570 depends on whether the target system supports this processor generation — verify against that system's CPU compatibility list.

Q: What is the TDP of the Xeon Silver 4114T in the 4XG7A07254?

A: The Thermal Design Power (TDP) is 85W. This is lower than the 105W variants in the Xeon Silver family, making it a better fit for high-density rack deployments with tighter per-slot thermal budgets.

Q: What is the maximum RAM supported by the Lenovo 4XG7A07254 processor?

A: The Xeon Silver 4114T supports up to 768GB of DDR4-SDRAM. Actual installed capacity in the SR570 depends on available DIMM slots and the specific server configuration ordered.

Q: Does the 4XG7A07254 support dual-processor configurations?

A: The Xeon Silver 4114T uses the UPI (Ultra Path Interconnect) bus, which is designed to support multi-socket configurations. Whether dual-processor operation is supported depends on the SR570 chassis configuration — verify with Lenovo's SR570 specification sheet for dual-CPU support details.

Q: What is the weight of the Lenovo 4XG7A07254?

A: Per distributor specifications, the 4XG7A07254 ships at 1.95 lbs.

James Everett

The 4XG7A07254 slots the Xeon Silver 4114T into the SR570 at an 85W TDP — that envelope is the defining spec when I'm sizing a high-density rack where facility cooling is the real constraint, not the server itself. Ten cores at 2.2GHz with a 3.0GHz turbo gives you a well-rounded mid-tier compute profile without the thermal overhead of the 105W+ options in the same Scalable family.

Technical Highlights:

• 85W TDP: Directly constrains per-rack BTU load — 85W vs. 105W across a 20-server rack is a 400W difference, which can be the margin that keeps you within a facility's per-row power envelope without upgrading PDUs or CRAC capacity.
• 768GB DDR4 Max Memory: The 4114T's memory ceiling is high enough for memory-intensive virtualization or in-memory analytics workloads. The limiting factor shifts from the CPU to the SR570's physical DIMM slot count and which LRDIMM/RDIMM configurations Lenovo supports at that capacity.
• LGA 3647 Platform Lock: Socket P is generation-specific — this CPU does not migrate to Ice Lake (Whitley) or later platforms. If your procurement window spans multiple server refresh cycles, confirm that your SR570 chassis is the target platform for the life of this component.

Deployment Considerations:

• In a dual-socket SR570 build, two 4114T CPUs give you 20 cores and 40 threads total across UPI — plan your NUMA topology before workload placement, particularly for latency-sensitive applications that don't cross NUMA nodes cleanly.
• The 14nm Skylake microarchitecture requires attention to microcode update status — MDS, Spectre/Meltdown, and related mitigations are well-established but do carry a measurable performance tax on specific workload types (system call-heavy applications in particular). Account for this in your benchmark baseline.

This processor is a solid fit for SR570 deployments in enterprise environments running VMware ESXi or Linux-based hypervisors where per-server power efficiency is a procurement criterion — particularly shared colocation facilities billing on per-amp circuit allocation.
