Lenovo 4XG7A09045 SR590 Xeon 6142 16C/150W/2.6GHZ

Lenovo 4XG7A09045 Xeon Gold 6142 16-Core Processor for SR590

Overview

The Lenovo 4XG7A09045 is a 1st Generation Intel Xeon Gold 6142 processor option for the ThinkSystem SR590 server platform — a 16-core, 32-thread CPU built for compute-dense workloads where thread count and memory headroom both matter. Running at a 2.6 GHz base with a 3.7 GHz Turbo Boost ceiling, it fits squarely in the mid-tier of the Lenovo server CPU lineup, pairing density with thermal manageability inside a 150W TDP envelope. If you're specifying SR590 configurations for video analytics, virtualization, or high-channel NVR back-end processing, this is the part number to source.

Key Features

• 16 Cores / 32 Threads (Skylake-SP, 14nm): The Skylake microarchitecture delivers mature, well-understood per-core performance. Thirty-two logical threads keep vCPU counts high in VMware or Hyper-V deployments — useful when you're consolidating multiple network video recorder workloads or running parallel analytics processes on a single host.
• 2.6 GHz Base / 3.7 GHz Turbo: The 1.1 GHz gap between base and boost means bursty single-threaded tasks — like video decoding spikes or short-lived analytics inference jobs — get headroom without you paying for a higher TDP chip across all cores all the time.
• 150W Thermal Design Power: At 150W, this falls within the SR590's supported TDP range and ships with a cooler included, so you won't need to source a separate thermal solution. Budget your rack PDU and UPS capacity accordingly — 150W per socket adds up in a multi-server bay.
• 22MB L3 Cache: The large L3 cache reduces main-memory round trips on working sets that fit — video frame buffers and analytics model weights that recur frequently benefit directly, keeping latency low between decode and inference stages.
• 768 GB Maximum Memory Support: The 6142 supports up to 768 GB of RAM per socket on LGA 3647 (Socket P). For surveillance servers running large in-memory databases, extended video retention indexes, or AI inference models loaded into RAM, that ceiling gives substantial growth runway without a processor swap.
• LGA 3647 (Socket P) Platform: Designed exclusively for the SR590 and compatible Purley-platform servers. This is not a drop-in for older Broadwell-EP or Haswell-EP systems — verify your SR590 system board revision supports 1st Gen Scalable before ordering.
• 64-bit / H0 Stepping: The H0 stepping is the production-stable revision of the Skylake-SP die. Relevant if your environment has microcode pinning requirements or specific BIOS compatibility constraints with earlier steppings.

Integration & Compatibility

The 4XG7A09045 is a Lenovo factory option kit for the ThinkSystem SR590 server. It is not a retail-boxed Intel part — it ships as a Lenovo-qualified component intended for installation into supported SR590 configurations. Verify your SR590 system board and BIOS revision against Lenovo's Hardware Compatibility List before committing to this part in a multi-socket or mixed-generation configuration. Pairing with appropriate DDR4 RDIMM or LRDIMM memory modules (sold separately) is required to reach the 768 GB memory ceiling. For deployments integrating with video management and NVR platforms, allocate memory and core count based on your concurrent stream decode and analytics load — 16 cores at this frequency handles substantial concurrent channel counts when the NVR software is properly licensed and configured.

Frequently Asked Questions

Q: What server platform is the Lenovo 4XG7A09045 compatible with?

A: The 4XG7A09045 is a Lenovo-qualified processor option for the ThinkSystem SR590 server. It uses the LGA 3647 (Socket P) socket and is designed for Purley-platform Lenovo servers supporting 1st Generation Intel Xeon Scalable processors. Verify BIOS and board revision compatibility before installation.

Q: Does the 4XG7A09045 include a cooler?

A: Yes. A cooler is included with this processor kit, so a separate thermal solution is not required for standard SR590 installation.

Q: What is the TDP of the Xeon Gold 6142?

A: The Xeon Gold 6142 has a Thermal Design Power (TDP) of 150W. Size your rack power distribution and UPS capacity accordingly, particularly in multi-socket or high-density server deployments.

Q: How many cores and threads does the 6142 provide?

A: The Intel Xeon Gold 6142 delivers 16 physical cores and 32 threads via Intel Hyper-Threading, running at a 2.6 GHz base frequency with a 3.7 GHz Turbo Boost ceiling.

Q: What is the maximum memory this processor supports?

A: The Xeon Gold 6142 supports up to 768 GB of memory per socket. Actual capacity depends on the SR590 system board configuration and the memory modules installed.

Q: Is this the same as a retail Intel Xeon Gold 6142 box processor?

A: No. The 4XG7A09045 is a Lenovo factory option kit, qualified and packaged specifically for ThinkSystem SR590 servers. It is not interchangeable with retail-boxed Intel processors and should only be installed in supported Lenovo platforms.

The 4XG7A09045 is one of those parts that sits in a practical sweet spot for SR590-based surveillance and analytics back-ends — 16 cores at 150W TDP with a 3.7 GHz Turbo ceiling gives you meaningful single-thread burst without the thermal overhead of the higher-core-count 200W+ chips in the same Scalable family. If you're spec'ing a ThinkSystem SR590 for a high-channel VMS deployment, this is a reasonable anchor processor before you decide whether a second socket is warranted.

Technical Highlights:

• 32-Thread Throughput at 150W: Sixteen Skylake-SP cores with Hyper-Threading gives you 32 logical processors inside a managed 150W envelope — relevant when your VMS or analytics platform licenses by vCPU and you need to maximize thread count without blowing the rack's power budget.
• 3.7 GHz Turbo Boost: The 1.1 GHz gap between base (2.6 GHz) and boost (3.7 GHz) is useful for video decode tasks that spike briefly — the processor can absorb those bursts without sustaining full-frequency power draw across all 16 cores simultaneously.
• 768 GB Memory Ceiling: On a single-socket SR590, supporting up to 768 GB of RAM means you're not going to be memory-constrained even in AI inference or large in-memory caching scenarios for extended video retention indexes.

Deployment Considerations:

• This is a Lenovo option kit, not a retail Intel part — it must be installed into a supported ThinkSystem SR590 with a confirmed compatible BIOS revision. Check Lenovo's Hardware Compatibility List before purchasing for an existing SR590 chassis.
• At 150W TDP, thermal and power headroom matter in dense deployments. A cooler is included, but confirm your SR590 chassis airflow configuration and PDU capacity before committing to multi-node builds at this TDP level.

Best fit for an SR590-based video analytics node where you need strong multi-threaded throughput for parallel stream processing and AI inference, but want to stay within a thermal envelope that doesn't require upgraded cooling infrastructure in an existing rack.
