Lenovo 4XG7A63480 Intel Xeon Gold 6336Y 24-Core Processor Option for ThinkSystem SR650 V2

Overview

The Lenovo 4XG7A63480 is a factory-configured processor option kit that installs the Intel Xeon Gold 6336Y into the Lenovo ThinkSystem SR650 V2 platform. Rated at 2.4 GHz base with a 3.6 GHz boost across 24 physical cores and 48 threads, the 6336Y sits in the Intel Xeon Gold 6000 Series — 3rd Generation Intel Xeon Scalable — built on a 10 nm process node and socketed to the LGA 4189 interface. If you are configuring a dual-socket SR650 V2 for compute-dense workloads such as video analytics, VMS server consolidation, or enterprise virtualization, the 4XG7A63480 is the factory add-in path that keeps the configuration within Lenovo's supported bill of materials.

Key Features

• 24 Cores / 48 Threads at 2.4 GHz Base: The 6336Y delivers 48 concurrent execution threads, which translates directly to higher VM density on a VMware or Hyper-V host — a second socket populated with this option effectively doubles thread count without adding a second chassis. For VMS deployments running Milestone XProtect or Genetec Security Center, more threads mean more simultaneous decode and analytics pipelines without saturating the CPU queue.
• 3.6 GHz Turbo Boost: Burst headroom to 3.6 GHz on lightly loaded cores means latency-sensitive workloads — live video decode, alarm event processing, access control transaction handling — get single-threaded performance where it counts, while background tasks (storage indexing, retention jobs) consume the remaining cores at base clock.
• 185W TDP: At 185W, this processor draws meaningfully more power than mid-range Xeon Gold parts. Confirm your SR650 V2 power supply and cooling configuration supports dual 185W sockets before ordering — Lenovo's configurator enforces this, but field upgrades require manual verification of installed PSU capacity and fan modules.
• 36 MB L3 Cache: 36 MB of last-level cache reduces main-memory round trips on data-intensive operations. For surveillance analytics engines that repeatedly reference model weights or frame buffers, a larger cache cuts latency on repeated access patterns compared to lower-cache Xeon options in the same socket family.
• 11.2 GT/s UPI System Bus: The 11.2 GT/s UltraPath Interconnect rate governs how fast the two sockets exchange data in a dual-socket SR650 V2 build. High UPI bandwidth matters in configurations where memory-mapped workloads — think in-memory databases backing access control or analytics — need to reach memory banks homed on the remote socket without a throughput penalty.
• Hybrid Core Architecture — 8 High-Priority + 16 Efficiency Cores: The 6336Y segments its 24 cores into 8 cores running at 2.5 GHz and 16 at 2.2 GHz. The OS scheduler can prioritize latency-sensitive threads onto the higher-frequency cluster, which benefits mixed workloads running real-time stream processing alongside batch reporting jobs on the same host.
• 10 nm Process Node, LGA 4189 Socket: The 10 nm lithography improves performance-per-watt compared to prior-generation 14 nm Xeon parts. The LGA 4189 socket is exclusive to Ice Lake Xeon Scalable — this option is not backward-compatible with SR650 Gen 1 or any non-LGA-4189 platform, so verify the exact chassis generation before ordering.
• 64-bit Operating Mode, 48 Threads: Full 64-bit instruction set support is a baseline requirement for all modern hypervisors and enterprise OS deployments. The 48-thread count directly maps to vCPU headroom — at a 4:1 vCPU-to-pCPU ratio, a dual-socket build supports up to 384 vCPUs before you hit physical thread limits.

Integration and Compatibility

The 4XG7A63480 is a rack server processor option validated exclusively for the Lenovo ThinkSystem SR650 V2. It installs into the LGA 4189 processor socket and requires matching DDR4 memory, compatible cooling hardware, and adequate power delivery — all of which Lenovo's system configurator enforces at point of order for new builds. For field upgrades into an existing SR650 V2, reference the Lenovo ServerProven compatibility matrix to confirm current firmware levels and any co-requisite parts (heat sinks, voltage regulators) before procurement.

In virtualized environments, the 6336Y's 48-thread count integrates with VMware vSphere, Microsoft Hyper-V, and KVM without modification. For network video recorder server builds — particularly large-channel Milestone, Genetec, or Avigilon Control Center deployments — pairing this processor option with adequate RAM and fast NVMe or SAS storage is where the real performance design work happens; the CPU itself is rarely the bottleneck once properly provisioned.

Organizations deploying this as part of a video management server stack should account for the 185W TDP in datacenter power and cooling budgets. A dual-socket configuration at full load approaches 370W from processor draw alone, before accounting for memory, storage, and network I/O. Proper UPS and power infrastructure planning is essential for any deployment targeting five-nines uptime.

Frequently Asked Questions

Q: What platform is the Lenovo 4XG7A63480 compatible with?

A: The 4XG7A63480 is a processor option validated for the Lenovo ThinkSystem SR650 V2. It installs into the LGA 4189 socket and is not compatible with prior SR650 generations or other server platforms.

Q: How many cores and threads does the Xeon Gold 6336Y provide?

A: The Intel Xeon Gold 6336Y delivers 24 physical cores and 48 threads. It operates at a 2.4 GHz base frequency with a 3.6 GHz boost, and segments cores into 8 high-priority (2.5 GHz) and 16 efficiency cores (2.2 GHz).

Q: What is the TDP of the 6336Y, and does it affect power supply requirements?

A: The 6336Y carries a 185W TDP. In a dual-socket SR650 V2, processor draw alone reaches approximately 370W at full load. Verify that your installed power supplies and cooling modules support this configuration before populating a second socket.

Q: Is the 4XG7A63480 suitable for VMS or video analytics server builds?

A: Yes. The 24-core/48-thread configuration and 36 MB L3 cache make this a capable choice for enterprise VMS platforms such as Milestone XProtect or Genetec Security Center, particularly in large-channel or multi-stream analytics deployments where thread density and cache size directly impact decode and analytics throughput.

Q: What memory type does the SR650 V2 with the 6336Y support?

A: The Intel Xeon Gold 6336Y (3rd Generation Xeon Scalable, Ice Lake) supports DDR4 memory. Specific speed grades and maximum capacity depend on the SR650 V2 memory configuration — consult the Lenovo ServerProven matrix for validated DIMM options.

James Everett

When I spec a server processor option like the 4XG7A63480 for a surveillance infrastructure build, the number I focus on first is the 185W TDP — not the core count. At 185W per socket, this part demands a properly sized PSU and validated cooling solution before you touch anything else. Get that wrong and you're troubleshooting thermal throttling under load six months into production.

Technical Highlights:

• 48 Execution Threads: In a dual-socket SR650 V2 build, you're looking at 96 threads total — enough headroom to run a large-channel VMS host, a dedicated analytics engine, and a hypervisor management layer without contention, assuming memory is provisioned correctly.
• 3.6 GHz Turbo: The jump from 2.4 GHz base to 3.6 GHz boost is a 50% frequency uplift on lightly loaded cores. For alarm-driven analytics workflows where most cores idle until motion events fire, this burst headroom keeps event-processing latency low without requiring a higher-TDP part.
• 36 MB L3 Cache: For AI inference workloads — object detection models running at the edge of the server before GPU offload — a larger L3 reduces DRAM fetches on repeated model-weight access, which matters when you are processing dozens of concurrent streams in software.

Deployment Considerations:

• LGA 4189 is an Ice Lake-exclusive socket — confirm the chassis is SR650 V2 (not SR650 Gen 1) before procurement, as the sockets are physically similar but electrically incompatible.
• At 185W TDP, dual-socket configurations at sustained load approach 370W from processors alone; factor in memory, NVMe, and 25GbE NICs and you need to validate your PDU circuit capacity before rack installation.

This option makes the most sense in large-scale VMS server builds — specifically deployments running 128-channel-plus Milestone or Genetec configurations where software decode, metadata indexing, and retention management all compete for CPU cycles simultaneously. For lighter deployments under 64 channels, a lower-TDP Xeon Gold option in the same SR650 V2 family will cost less to operate and cool.
