Lenovo 7XG7A05578 SR650 Xeon 4114 10C/85W/2.2GHZ

Lenovo 7XG7A05578 Xeon 4114 10-Core Processor for ThinkSystem SR650

Overview

The Lenovo 7XG7A05578 is a factory-configured Intel Xeon Silver 4114 processor option for the ThinkSystem SR650 rack server. Running 10 cores and 20 threads at a 2.2 GHz base clock with a 3.0 GHz Turbo Boost ceiling, this Skylake-SP component targets compute workloads that benefit from high thread counts without pushing into the thermal or power envelope of higher-bin Xeon Gold or Platinum parts. At 85W TDP, it fits within standard SR650 cooling configurations without requiring upgraded fans or additional thermal management. If you're speccing a mid-density virtualization node, a rack server for a surveillance VMS backend, or a multi-tenant application platform, the 4114 hits a deliberate balance point between per-core performance and total power draw.

Key Features

• 10 Cores / 20 Threads at 2.2–3.0 GHz: The 7XG7A05578 delivers 20 logical processors to the OS — enough headroom for vSphere or Hyper-V environments running 8–15 concurrent VMs on a single socket, or for Milestone XProtect / Genetec Security Center backends processing multiple simultaneous video streams without a dedicated GPU decode offload.
• 3.0 GHz Turbo Boost: Single-threaded workloads — SQL queries, license-plate recognition tasks, or VMS analytics correlation — can burst to 3.0 GHz on active cores, giving snappier response on latency-sensitive jobs without requiring a higher base-clock SKU at greater power cost.
• 85W Thermal Design Power: 85W TDP means this processor fits within the SR650's base thermal envelope. Compared to 105W or 125W Xeon Gold variants, you get meaningful power savings in always-on server environments — over a 3-year deployment, the difference compounds against your data center PUE and power costs.
• 13.75 MB L3 Cache: The 13.75 MB last-level cache reduces main-memory access frequency on repetitive workloads like database queries or video indexing — translating to lower latency on cache-resident hot data sets typical in security event databases.
• Up to 768 GB DDR4 Memory Support: The 4114 supports up to 768 GB of system RAM across the SR650's DIMM slots — sufficient to load large in-memory analytics datasets, run memory-intensive VMs, or support AI-inference acceleration layers without swapping to disk.
• 9.6 GT/s UPI System Bus: The 9.6 GT/s Ultra Path Interconnect bus rate supports tight coordination between processor and I/O subsystems, keeping NVMe storage and network adapter throughput from bottlenecking on inter-fabric latency.
• LGA 3647 (Socket P) with 1st Gen Xeon Scalable Compatibility: Socketed on the standard LGA 3647 / Socket P platform — the same socket shared across the SR650's supported processor range. This means the 7XG7A05578 can be installed as an initial single-socket configuration with a second socket populated later if workloads grow, without a platform change.
• 14nm Skylake-SP Architecture: Built on Intel's mature 14nm Skylake-SP process node, the 4114 benefits from a well-understood silicon platform with broad OS, hypervisor, and firmware support — no edge-case driver gaps on enterprise Linux or Windows Server deployments.

Integration & Compatibility

The 7XG7A05578 is a Lenovo-qualified processor option for the Lenovo ThinkSystem SR650 platform. As a factory-configured component, it is validated against the SR650's board management controller, UEFI firmware, and thermal subsystem — avoiding the compatibility uncertainty that comes with aftermarket processor sourcing. The LGA 3647 socket supports the full 1st Generation Intel Xeon Scalable family, giving you a clear upgrade path to higher-core-count or higher-frequency SKUs within the same platform generation if your workload scales.

In network video recorder and VMS server deployments, this processor pairs naturally with adequate DDR4 ECC memory and a surveillance-grade storage array. For environments running Genetec, Milestone, or Avigilon Control Center on dedicated server hardware, the 10-core / 20-thread configuration handles concurrent stream decoding, motion indexing, and alert processing without saturating the CPU — particularly when combined with a RAID controller offloading storage I/O from the main processor pipeline.

For data center and enterprise IT environments, the SR650 platform with a 4114 processor is a functional fit for two-socket rack server deployments where the second socket can be populated later, and for virtualization clusters where a predictable, lower-TDP node is preferable to an overprovisioned high-core-count variant. Pair with appropriate server memory for your target VM density.

Frequently Asked Questions

Q: What server platform is the Lenovo 7XG7A05578 designed for?

A: The 7XG7A05578 is a Lenovo-qualified Intel Xeon Silver 4114 processor option for the ThinkSystem SR650 rack server platform. It uses the LGA 3647 (Socket P) socket and is validated for that specific platform.

Q: What is the base and boost clock speed of the 4114 processor in this configuration?

A: The processor runs at a 2.2 GHz base frequency and can boost to 3.0 GHz on active cores under Turbo Boost.

Q: How many cores and threads does the 7XG7A05578 provide?

A: It provides 10 physical cores and 20 threads via Intel Hyper-Threading, presenting 20 logical processors to the host operating system or hypervisor.

Q: What is the TDP of this processor, and does it require upgraded cooling in the SR650?

A: The Xeon Silver 4114 has an 85W Thermal Design Power rating, which fits within the SR650's standard cooling configuration without requiring upgraded fan modules.

Q: What is the maximum RAM this processor supports?

A: The Intel Xeon Silver 4114 supports up to 768 GB of DDR4 memory, subject to the SR650's physical DIMM slot and memory configuration constraints.

Q: Can this processor be used in a single-socket SR650 configuration with the second socket added later?

A: Yes. The SR650 supports single-socket and dual-socket configurations on the LGA 3647 platform. You can deploy with one 7XG7A05578 initially and populate the second socket with a compatible 1st Gen Xeon Scalable processor as workloads grow.

The 7XG7A05578 is a deliberate mid-tier pick in the SR650 processor lineup — the Xeon Silver 4114's 85W TDP is the spec I keep coming back to when scoping always-on server environments where power and cooling budgets are real constraints, not afterthoughts. Ten cores at 2.2 GHz base with a 3.0 GHz boost ceiling gives you enough logical processor headroom for the workloads that dominate physical security and enterprise IT backends without running a 125W part in a chassis that will sit powered on for five years.

Technical Highlights:

• 20 Logical Processors: 10 cores with Hyper-Threading gives hypervisors 20 schedulable threads — practical for 8–15 moderate-density VMs on a single socket, or for VMS backends that need concurrent stream decoding without dedicated decode hardware.
• 768 GB Maximum Memory: The 4114's memory ceiling is high enough to avoid artificial limits on in-memory database or analytics workloads, which matter if you're running event-correlation or AI-inference layers alongside the core VMS on the same server.
• 9.6 GT/s UPI Bus: The interconnect rate keeps pace with high-throughput NVMe arrays and 25GbE adapters — you're not leaving bandwidth on the table at the storage or network fabric layer on a well-configured SR650.

Deployment Considerations:

• This is a 1st Gen Xeon Scalable (Skylake-SP) part — confirm your SR650 firmware revision supports this generation before deployment; Lenovo SR650 UEFI has multiple generations that affect processor compatibility.
• At 85W, thermal headroom is comfortable for standard configurations, but dual-socket builds with two 4114s will draw 170W from processors alone — factor that into PDU and UPS capacity planning for dense rack deployments.

Best fit: a single-socket SR650 deployed as a dedicated VMS recording and analytics server in a medium-scale physical security environment — 32–128 cameras — where you want predictable power draw and a clear path to second-socket expansion if the channel count grows.
