Lenovo 7XG7A05601 SR650 Xeon 6142 16C/150W/2.6GHZ

Lenovo 7XG7A05601 Intel Xeon Gold 6142 16-Core Processor for ThinkSystem SR650

Overview

The Lenovo 7XG7A05601 is a factory-new Intel Xeon Gold 6142 processor option kit designed specifically for the ThinkSystem SR650 server platform. Running 16 cores and 32 threads at a 2.6 GHz base clock — with Turbo Boost headroom up to 3.7 GHz — this 1st Generation Intel Xeon Scalable processor handles the parallel workloads that drive video analytics servers, large-scale NVR back-ends, and enterprise surveillance management platforms. If you're building or expanding a compute node that needs to handle concurrent video decoding, AI inferencing pipelines, or VMS database operations across dozens of simultaneous camera streams, the 7XG7A05601 is worth understanding before you spec the rest of the chassis.

Key Features

• 16 Cores / 32 Threads (Skylake, 14 nm): Intel's Skylake-SP microarchitecture on the LGA 3647 (Socket P) platform delivers true per-core performance that matters when your VMS or analytics engine can't simply queue work — concurrent decode of 64+ streams benefits directly from the 16-core count rather than relying entirely on GPU offload.
• 2.6 GHz Base / 3.7 GHz Boost Clock: The 1.1 GHz Turbo spread means bursty single-threaded tasks (licensing checks, metadata indexing, API calls from client workstations) get handled quickly without sustained base-clock penalty on background decode threads running in parallel.
• 22 MB L3 Cache: A large on-die cache reduces main-memory round trips for hot working sets — relevant for video analytics workloads that repeatedly reference the same motion-detection model weights or frame buffers across multiple streams.
• 150 W TDP: The 150 W thermal envelope is on the higher end of the Xeon Gold 6000 family. Confirm your SR650 chassis cooling configuration and power supply headroom before deploying — this processor will draw the full budget under sustained load, and the kit ships without a cooler included.
• LGA 3647 (Socket P) — SR650 Platform: This processor is a platform-specific option kit matched to the ThinkSystem SR650. It is not a retail-boxed part — it's validated for insertion into an SR650 that currently runs a lower-tier or single-socket configuration, making it the correct procurement path for capacity upgrades through proper server channels.
• 64-Bit / 32 Operating Threads: Full 64-bit support with 32 logical threads via Hyper-Threading means virtualization hosts running surveillance-adjacent workloads (VM-based NVR instances, containerized analytics) can schedule more concurrent vCPUs before hitting contention — a real factor if your SR650 is running three or four VMs off a single processor socket.
• Intel Xeon Gold 6000 Series Lineage: The Gold tier in the 1st Gen Scalable family supports dual-socket configurations, advanced RAS (Reliability, Availability, Serviceability) features, and Intel Advanced Vector Extensions 512 (AVX-512) — the instruction set that accelerates deep learning inference natively on CPU, useful when a GPU accelerator is not in the budget or chassis configuration.

Integration & Compatibility

The 7XG7A05601 is validated for the Lenovo ThinkSystem SR650 server. Before ordering, verify the target SR650's system board revision supports 1st Generation Xeon Scalable processors — some later SR650 boards shipped with 2nd Gen (Cascade Lake) only. Cross-reference the Lenovo ServerProven compatibility database using the chassis serial number. The LGA 3647 socket accepts both 1st and 2nd Gen Xeon Scalable physically, but firmware and QVL validation are the governing factors, not socket fit alone. This processor kit does not include a thermal solution — ensure your SR650 has the correct heat sink (standard or high-performance depending on airflow configuration) already installed or on order before commission.

Frequently Asked Questions

Q: Is the 7XG7A05601 compatible with all SR650 configurations?

A: The 7XG7A05601 is validated for the ThinkSystem SR650 platform. However, compatibility depends on the specific SR650 board revision and firmware level. Always cross-reference Lenovo's ServerProven tool with your chassis serial number before ordering.

Q: Does the 7XG7A05601 include a heatsink or cooler?

A: No. The cooler is not included with this processor option kit. You must have the appropriate SR650 heat sink installed separately before commissioning the processor.

Q: What is the base and boost clock speed of the Xeon Gold 6142?

A: The processor runs at a 2.6 GHz base frequency with Intel Turbo Boost up to 3.7 GHz, giving you 1.1 GHz of headroom for bursty workloads without sacrificing sustained multi-threaded throughput.

Q: How many cores and threads does the 7XG7A05601 provide?

A: The Intel Xeon Gold 6142 delivers 16 physical cores and 32 threads via Hyper-Threading, running in 64-bit mode.

Q: What socket does the Xeon Gold 6142 use?

A: LGA 3647 (Socket P) — the standard socket for 1st Generation Intel Xeon Scalable processors on the SR650 platform.

Q: What is the TDP of the 7XG7A05601 and does it affect power planning?

A: The Xeon Gold 6142 has a 150 W TDP. Under sustained compute workloads, it draws the full budget — confirm your SR650 power supply configuration and chassis airflow before deployment, especially in multi-processor or high-density rack scenarios.

Karl Wilson

The 7XG7A05601 is one of those processor upgrades that looks straightforward on paper but has a few installation gates worth flagging. The Xeon Gold 6142's 150 W TDP is the first one — this isn't a low-power data-center part, and the SR650's power delivery and cooling zones need to be confirmed before you drop it in. Done right, the 16-core / 32-thread configuration is a strong fit for surveillance compute nodes running parallel video analytics or multi-tenant VMS workloads where per-socket thread count directly limits concurrent stream handling.

Technical Highlights:

• 16C / 32T at 2.6–3.7 GHz: The 1.1 GHz Turbo range gives you responsive single-threaded headroom for management API calls while sustaining high throughput on decode-heavy backgrounds — two workload profiles that constantly coexist in production VMS environments.
• 22 MB L3 Cache: Large enough to keep hot analytics model state on-die during inference loops, reducing the latency penalty of main-memory fetches when processing high frame-rate streams across multiple channels.
• Skylake-SP / AVX-512 Support: Native AVX-512 on the Gold tier means CPU-side deep learning inferencing (object classification, motion filtering) is viable without a discrete GPU — an option worth preserving for smaller deployments or budget-constrained expansions.

Deployment Considerations:

• This is an option kit, not a retail-boxed CPU — procurement and installation should follow Lenovo's SR650 processor installation procedures, including torque specs and firmware update sequencing before first POST.
• No cooler is included. Verify the correct SR650 heat sink variant (standard vs. high-performance) against your chassis airflow config before the processor arrives — this is a common delay point on SR650 upgrades.

Best fit: a ThinkSystem SR650 deployed as a dedicated VMS compute node or edge analytics server where the existing processor socket is being upgraded to handle 64+ concurrent camera streams, and where AVX-512 CPU inferencing offloads GPU budget to other line items.
