Lenovo 7XG7A05554 SR630 Xeon 6146 12C/165W/3.2GHZ

Lenovo 7XG7A05554 Intel Xeon Gold 6146 12-Core Processor Option for ThinkSystem SR630

Overview

The Lenovo 7XG7A05554 is an Intel Xeon Gold 6146 processor option kit designed for the Lenovo ThinkSystem SR630 1U rack server. Running 12 cores and 24 threads at a 3.2 GHz base clock — with a 4.2 GHz Turbo Boost ceiling — this 1st Generation Intel Xeon Scalable processor targets compute-intensive workloads where per-core throughput matters: VMS analytics, AI inferencing at the edge, database-backed access control platforms, and multi-stream video transcoding. If you are speccing a SR630 that needs to push serious single-threaded performance alongside meaningful parallelism, the 6146 sits at the upper end of the Xeon Gold 6000 tier and warrants a closer look before defaulting to a higher core-count, lower-frequency alternative.

At 165W TDP, the 7XG7A05554 requires a thermal solution matched to that envelope — confirm your SR630 chassis configuration and cooling tier before ordering. The processor installs in the LGA 3647 (Socket P) primary or secondary CPU slot of the SR630, enabling dual-socket deployments when maximum aggregate throughput is the goal.

Key Features

• 3.2 GHz Base / 4.2 GHz Turbo Boost: The 1 GHz headroom between base and boost matters for mixed workloads. Single-threaded tasks — license plate recognition, analytics inference, alarm-triggered recording bursts — get the full 4.2 GHz ceiling, while sustained parallel encode/decode workloads settle at the 3.2 GHz base. Few Xeon Gold 6000-series parts combine this clock speed range with 12 cores, making the 6146 a strong fit for latency-sensitive VMS or access control servers that also run background batch jobs.
• 12 Cores / 24 Threads (Hyper-Threading): Twenty-four logical processors give the OS enough headroom to schedule concurrent workloads without context-switch bottlenecks. In a multi-camera NVR or VMS host, each decoding thread, analytics worker, and storage I/O thread competes for CPU time — 24 logical cores keep queues shallow and latency predictable under peak load.
• 24.75 MB L3 Cache: A large last-level cache reduces off-die memory latency for working sets that fit inside it. For database-backed access control platforms and VMS index tables, this means fewer main-memory fetches per lookup — measurable in sustained IOPS throughput when storage is the bottleneck rather than the CPU.
• 14 nm Skylake Microarchitecture (Stepping H0): The Skylake-SP design generation brought AVX-512 instruction support to the Xeon Scalable family — relevant for AI inferencing and signal processing workloads that compilers and frameworks can vectorize. If your VMS vendor or analytics engine ships AVX-512 optimized binaries, this matters for frames-per-second throughput per watt.
• UPI (Ultra Path Interconnect) Fabric: In dual-socket SR630 configurations, UPI replaces the older QPI interconnect for processor-to-processor communication. Higher bandwidth and lower latency across the socket boundary means workloads that span both sockets — large in-memory databases, distributed VMS analytics — scale more predictably than on older-generation platforms.
• 165W TDP with LGA 3647 (Socket P) Mounting: The 165W thermal envelope sits above mid-range Xeon Gold parts, so verify your SR630 is configured with the appropriate heatsink and chassis cooling capacity. In properly specced SR630 deployments, this TDP is well within the platform's thermal design — but it is not a drop-in for SR630 configurations specced around lower-wattage CPUs without confirming the cooling bill of materials.
• 64-Bit Operating Mode / 24-Thread Addressability: Supports all mainstream enterprise operating systems and hypervisors. For virtualized VMS or access control deployments running multiple OS instances on a single SR630, the 24 logical cores give the hypervisor enough headroom to partition workloads without resource contention under normal operating conditions.

Integration and Compatibility

The 7XG7A05554 is engineered specifically for the Lenovo ThinkSystem SR630 platform. It occupies the LGA 3647 Socket P, which is the socket standard across 1st Generation Intel Xeon Scalable deployments. Dual-socket SR630 configurations can pair two 6146 processors for a combined 24-core, 48-thread compute pool — a configuration worth evaluating for large-scale VMS deployments with on-board analytics, where aggregate thread count and L3 cache capacity both factor into throughput.

This processor belongs to the Intel Xeon Gold 6000 Series within the broader 1st Generation Intel Xeon Scalable family, meaning it is compatible with DDR4 memory and the full SR630 I/O and PCIe ecosystem. For rack server deployments in physical security operations centers or data-center-adjacent VMS environments, the SR630 platform supports the full range of PCIe-attached GPU accelerators, RAID controllers, and NIC options that enterprise video management infrastructure demands. Buyers integrating this into a security server build should cross-reference the SR630 configuration guide to confirm memory channel population and PCIe slot allocation alongside this processor option. See the full Lenovo server and compute catalog for compatible platform accessories and expansion options. If you are planning storage-intensive VMS recording alongside analytics, a high-density PoE switching layer upstream of the server is worth scoping in the same planning pass.

The 7XG7A05554 is a processor I recommend when an integrator needs single-threaded punch alongside respectable parallelism in a 1U form factor — specifically, the 4.2 GHz Turbo Boost ceiling on a 12-core part is a combination you do not see often in the Xeon Gold 6000 lineup. Most high-core-count parts trade clock speed for density; the 6146 makes the opposite bet.

Technical Highlights:

• 4.2 GHz Turbo Boost: The highest boost frequency in the Xeon Gold 6000 series at this core count — latency-sensitive VMS analytics and license plate recognition workloads will see the benefit directly in frames-processed-per-second under burst load.
• 24.75 MB L3 Cache: Enough cache to hold the working set of a mid-scale VMS event index or an access control database query buffer in-die — reduces the memory bandwidth tax that shows up as latency spikes under concurrent read/write load.
• 165W TDP on a 14nm Skylake-SP die: This is a hot part for its era. In a properly cooled SR630 it runs fine, but the 165W envelope means you need to confirm the heatsink SKU in your SR630 configuration matches — Lenovo's configuration guide differentiates heatsinks by CPU wattage tier.

Deployment Considerations:

• If you are dropping this into an existing SR630 that was previously specced with a lower-TDP processor, check the installed heatsink part number before powering on — the 165W thermal requirement is non-negotiable and under-cooling will trigger thermal throttling that erases the performance advantage.
• The UPI interconnect only matters in dual-socket builds. Single-socket SR630 deployments will not see UPI bandwidth; those buyers should weigh whether the 6146's clock speed justifies its cost over a lower-TDP 6-core alternative if their workload is not thread-saturating.

The 7XG7A05554 is the right call for a dedicated VMS analytics host running 64+ camera channels with on-box motion search and AI classification — where per-core clock speed drives user-facing query latency and the 165W power budget is acceptable inside a rack PDU already sized for a full SR630 build.
