Lenovo 7XG7A06282 SN850 Xeon 5118 12C/105W/2.3GHZ

Lenovo 7XG7A06282 Intel Xeon Gold 5118 12-Core Server Processor

Overview

The Lenovo 7XG7A06282 is an Intel Xeon Gold 5118 processor option for the Lenovo ThinkSystem SN850 server platform. Built on Intel's first-generation Xeon Scalable architecture (Skylake), the 5118 delivers 12 cores and 24 threads at a 2.3 GHz base frequency with a 3.2 GHz Turbo Boost ceiling — a well-balanced configuration for mid-range compute workloads where thread count and memory bandwidth matter more than raw single-core clock speed. At 105W TDP, it fits squarely in the standard Xeon Scalable thermal envelope, which matters when you're planning rack density and cooling budget for multi-socket SN850 deployments.

This SKU is factory-sourced for the Lenovo server and compute portfolio, ensuring platform compatibility with ThinkSystem firmware and configuration tooling. If you're building or expanding an SN850-based server infrastructure, the 7XG7A06282 is the channel-direct path to a genuine, factory-new processor option.

Key Features

• 12 Cores / 24 Threads: The 5118's 12-core, 24-thread layout handles parallel workloads — virtualization, containerized applications, analytics pipelines — without the licensing overhead that comes with higher core-count Xeon Platinum SKUs. For workloads that scale with thread count rather than single-thread performance, this is a cost-efficient lane.
• 2.3 GHz Base / 3.2 GHz Turbo Boost: The 900 MHz headroom between base and boost means lightly-threaded tasks get a meaningful clock uplift automatically, while sustained all-core workloads settle at the 2.3 GHz base. Plan your performance modeling around base for sustained compute, boost for bursty or latency-sensitive jobs.
• 16.5 MB L3 Cache: 16.5 MB of L3 across 12 cores — roughly 1.375 MB per core — reduces main memory round-trips on working sets that fit within cache. For in-memory database queries and tightly-looped analytics, cache capacity at this level makes a measurable difference in throughput.
• 105W TDP: At 105W, the 5118 stays within the standard Xeon Scalable thermal design envelope. In multi-socket SN850 configurations, this means predictable cooling requirements per socket — no special high-TDP cooling infrastructure required compared to 150W+ Platinum variants.
• DDR4-2400 Support, Up to 768 GB per Processor: The 5118 supports DDR4-2400 MHz memory and can address up to 768 GB per processor socket. In a multi-socket SN850, total addressable memory scales with socket count — relevant for memory-intensive workloads like large virtual machine pools or in-memory data processing.
• LGA 3647 (Socket P): The LGA 3647 socket is the standard first-gen Xeon Scalable interface on Lenovo ThinkSystem platforms. This socket compatibility is the primary platform gate — confirm your SN850 board revision and UEFI version support this processor before ordering.
• 14nm Skylake Lithography: The Skylake process node is mature and well-characterized for thermal and power behavior. Predictable operating characteristics simplify thermal modeling for high-density rack deployments.
• 64-Bit Operating Mode: Full 64-bit instruction support is standard for any modern server workload — relevant here primarily as a confirmation that no 32-bit OS or legacy PAE constraints apply.

Integration & Compatibility

The 7XG7A06282 is designed for the Lenovo ThinkSystem SN850 server platform. The SN850 is a multi-socket blade server supporting first-generation Intel Xeon Scalable processors via the LGA 3647 (Socket P) interface. Before installation, verify the following against your specific SN850 configuration:

• Socket availability: The SN850 supports multiple processor sockets; confirm the target socket is populated correctly and that the system UEFI firmware revision supports the Xeon Gold 5118 stepping.
• Memory configuration: DDR4-2400 is the supported memory speed for this processor. Installing faster DIMMs will operate at 2400 MHz — not a problem, but plan accordingly so you're not paying for headroom you won't use at this processor tier.
• Power budget: At 105W TDP per socket, calculate total chassis power draw across all populated sockets. The SN850 chassis power supply and cooling must be provisioned to handle the aggregate thermal load, particularly in fully-populated multi-socket configurations running sustained workloads.
• Platform tooling: Lenovo XClarity Administrator and ThinkSystem UEFI configuration utilities apply standard first-gen Xeon Scalable support for this processor. No special firmware branches required for the 5118 specifically.

The Lenovo 7XG7A06282 is a focused mid-range processor option for SN850 deployments where you need solid multi-threaded throughput without climbing into the Xeon Platinum TDP and licensing brackets. The 12-core / 24-thread count at 105W is the practical sweet spot for virtualization hosts and analytics nodes where per-core software licensing makes the jump to 16- or 20-core variants an expensive proposition rather than a performance win.

Technical Highlights:

• 12C/24T at 105W: Delivers substantial parallel compute within the standard SN850 thermal envelope — no chassis cooling upgrade required versus lower-TDP options, and you retain the full thread count for VM density planning.
• 3.2 GHz Turbo Boost: The 900 MHz boost headroom above the 2.3 GHz base is meaningful for latency-sensitive workloads — single-threaded database queries, management plane tasks, or burst compute jobs that don't saturate all 12 cores simultaneously.
• 768 GB DDR4-2400 per socket: In a multi-socket SN850 build, memory addressability scales across sockets. At 768 GB per socket, this processor supports large VM pools and in-memory workloads without requiring processor upgrade to access the memory capacity tier.

Deployment Considerations:

• Verify SN850 UEFI firmware revision supports the Xeon Gold 5118 stepping before scheduling a maintenance window — Lenovo XClarity can confirm compatibility against your chassis firmware level prior to installation.
• DDR4-2400 is the hard ceiling for memory speed with this processor; if memory bandwidth is a primary constraint for your workload, consider whether the 5118 or a higher-frequency-capable Xeon variant better fits your memory subsystem design before committing to this SKU.

Best fit for SN850-based virtualization hosts and analytics nodes where per-core licensing cost is a real budget constraint and 12 cores at full DDR4-2400 memory bandwidth covers the workload envelope without overspending on socket TDP.
