Lenovo 7XG7A05575 SR650 Xeon 4110 8C/85W/2.1GHZ

Lenovo 7XG7A05575 Xeon Silver 4110 8-Core Processor for SR650

Overview

The Lenovo 7XG7A05575 is a factory-configured Intel Xeon Silver 4110 processor option for the ThinkSystem SR650 server platform. Rated at 85W TDP with 8 cores running at a 2.1 GHz base clock (boosting to 3.0 GHz under single-core load), this first-generation Intel Xeon Scalable part targets SR650 deployments where you need multi-threaded compute headroom without the power and cost overhead of Gold or Platinum SKUs. If you're sizing a new SR650 build or adding a second socket to an existing chassis, the 7XG7A05575 is the entry point into the 8-core Silver tier.

Key Features

• 8 Cores / 16 Threads at 85W TDP: The Xeon Silver 4110 runs 16 concurrent threads inside an 85W envelope — meaningful for SR650 deployments where rack power is constrained. You get genuine parallel throughput for NVR management software, VMS analytics engines, or database workloads without pushing into the 105W+ Gold tier and its associated PSU and cooling implications.
• 2.1 GHz Base / 3.0 GHz Boost: The 900 MHz burst headroom matters for latency-sensitive single-threaded operations — SQL query parsing, VMS event indexing, access control transaction processing — where the base clock alone would be a bottleneck. Workloads that keep all 8 cores busy will settle near base; bursty workloads see the full 3.0 GHz ceiling.
• 11 MB L3 Cache: The 11 MB shared L3 keeps frequently accessed working sets (video frame buffers, analytics model weights, OS kernel structures) on-die rather than round-tripping to DRAM. On an SR650 running concurrent camera streams, that translates to lower latency per decode operation and more consistent frame processing throughput.
• LGA 3647 (Socket P) — Dual-Socket Capable: The SR650 chassis supports two LGA 3647 sockets. Installing the 7XG7A05575 as a second processor doubles available core count and memory channels without a chassis swap — a straightforward path to scale if your NVR or analytics workload grows past what a single socket can handle.
• 14nm Lithography / U0 Stepping: The U0 stepping is the production-stable revision of the first-generation Xeon Scalable family, with Intel's errata corrections applied. On a server that may run continuously for years, stepping matters — U0 is the version to target, not earlier B0 samples.
• 64-Bit Operating Mode / 16 Threads: Full 64-bit instruction support ensures compatibility with any current server OS (Windows Server, RHEL, Ubuntu LTS) and virtualization hypervisors (VMware ESXi, Hyper-V, KVM). The 16-thread count is directly relevant if you're licensing per-core VMS software — know your thread count before purchasing licenses.
• Cooler Included: The processor ships with a cooler, eliminating a separate procurement step. On an SR650 build, this matters for staging — you're not waiting on a separate heatsink order before the server can be commissioned.

Integration and Compatibility

The 7XG7A05575 is specifically qualified for the Lenovo ThinkSystem SR650 platform via the LGA 3647 Socket P interface. It slots into the first-generation Intel Xeon Scalable (Skylake-SP) ecosystem, which means it is compatible with DDR4 memory channels and the SR650's UPI interconnect for dual-socket configurations. Before ordering, confirm your SR650's firmware revision supports first-generation Xeon Scalable processors — Lenovo published platform-level compatibility matrices for the SR650 that distinguish between first-gen (Skylake-SP) and second-gen (Cascade Lake-SP) processor support. Do not mix Skylake-SP and Cascade Lake-SP processors in a dual-socket configuration; Intel's architecture requires matched generations per UPI link. The UNSPSC code 43201503 classifies this as a microprocessor component, consistent with how enterprise procurement systems and ERP platforms (SAP, Oracle) will categorize it on a PO.

Frequently Asked Questions

Q: What server platform is the Lenovo 7XG7A05575 designed for?

A: The 7XG7A05575 is a processor option for the Lenovo ThinkSystem SR650 server. It uses the LGA 3647 (Socket P) interface and is based on the first-generation Intel Xeon Scalable architecture (Skylake-SP).

Q: How many cores and threads does the Xeon Silver 4110 in the 7XG7A05575 provide?

A: The Xeon Silver 4110 provides 8 cores and 16 threads, operating at a 2.1 GHz base frequency with a turbo boost up to 3.0 GHz.

Q: What is the TDP of the 7XG7A05575 processor?

A: The processor has a Thermal Design Power (TDP) of 85W. This is within the standard SR650 thermal envelope and does not require upgraded cooling beyond what ships with the unit.

Q: Does the 7XG7A05575 include a cooler?

A: Yes. A cooler is included with the 7XG7A05575 processor, so no separate heatsink procurement is required for SR650 installation.

Q: Can the 7XG7A05575 be used in a dual-socket SR650 configuration?

A: Yes. The SR650 supports two LGA 3647 sockets. The 7XG7A05575 can serve as either the primary or secondary processor in a dual-socket build, doubling available cores and memory channels. Both sockets must be populated with first-generation Xeon Scalable processors — do not mix generations.

Q: Is the 7XG7A05575 compatible with second-generation Xeon Scalable (Cascade Lake) processors in the same server?

A: No. Intel's Xeon Scalable architecture requires matched generations in a dual-socket configuration. The 7XG7A05575 (Skylake-SP, first generation) cannot be paired with a Cascade Lake-SP processor in the same SR650 chassis.
