Lenovo 4XG7A63439 Intel Xeon Gold 6336Y 24-Core Processor Option for ThinkSystem SR630 V2

Overview

The Lenovo 4XG7A63439 is the factory-configured Intel Xeon Gold 6336Y processor option for the ThinkSystem SR630 V2 rack server — a 3rd Generation Intel Xeon Scalable processor running 24 cores at a 2.4 GHz base with a 3.6 GHz boost. This part number is how Lenovo structures its configure-to-order (CTO) server platform: you're selecting a specific CPU tier for an SR630 V2 chassis build, not a standalone boxed processor. If you're expanding compute density in a 1U dual-socket rack environment or need to match an existing SR630 V2 configuration, the 4XG7A63439 is the correct Lenovo catalog entry for this processor tier.

Key Features

• 24 Cores / 48 Threads (3rd Gen Xeon Scalable): The 6336Y's 24-core, 48-thread layout handles parallel workloads — virtualized environments, containerized services, or high-camera-count VMS platforms — without requiring a second socket to meet thread demands. More threads per socket means fewer VMs starved for CPU time during simultaneous recording and analytics tasks.
• 2.4 GHz Base / 3.6 GHz Boost Frequency: The 1.2 GHz spread between base and boost gives the scheduler meaningful headroom. Single-threaded latency-sensitive tasks (database queries, VMS event triggers) can burst to 3.6 GHz while background encode/decode workloads run at steady base clocks — reducing response jitter without burning peak thermal budget continuously.
• Asymmetric Core Configuration (8 High-Priority + 16 Standard): The 6336Y implements Intel's hybrid-priority core structure: 8 high-priority cores run at 2.5 GHz and 16 standard cores at 2.2 GHz. Workload schedulers that are priority-core-aware can pin latency-sensitive threads to the faster cores while offloading batch processing to the efficiency cores — a useful architecture for mixed VMS + analytics + storage management workloads on a single host.
• 36 MB Last-Level Cache: 36 MB of L3 cache reduces DRAM round-trips for working datasets that fit — particularly relevant for in-memory databases, caching layers, or NVR index structures where repeated random access to the same metadata would otherwise pressure memory bandwidth.
• 185W TDP: At 185W, this is a high-wattage processor tier. Confirm your SR630 V2 chassis is configured with adequate power supply capacity and that your rack PDU can support the resulting per-1U draw before deploying in a dense rack. Thermal planning matters here — do not assume a single PSU configuration is sufficient in dual-socket or high-memory configurations.
• 48 Logical Processors via Hyper-Threading: 48 logical cores visible to the OS increases VM density on hypervisors like VMware vSphere or Microsoft Hyper-V. For VMS deployments running camera streams as individual vCPU-pinned VMs, more logical cores directly translates to more concurrently active camera feeds without contention.
• 11.2 GT/s System Bus Rate: The 11.2 GT/s UPI interconnect rate (LGA 4189 socket, Ice Lake-SP architecture) ensures low-latency coherency between the two processor sockets in a dual-socket SR630 V2 configuration. In memory-bandwidth-bound workloads (video analytics inference, large frame buffers), UPI throughput affects how well the second socket can access memory attached to the first.
• 64-Bit Operating Modes / 10 nm Lithography: Built on Intel's 10 nm SuperFin process, the 6336Y delivers the efficiency improvements of the Ice Lake-SP generation versus the prior Cascade Lake generation — meaning you get more compute per watt than an equivalent-core-count previous-generation Xeon, relevant when comparing power budgets across a multi-year refresh cycle.

Integration and Compatibility

The 4XG7A63439 is a Lenovo-qualified processor option for the ThinkSystem SR630 V2 platform. The SR630 V2 uses the LGA 4189 socket (Ice Lake-SP, 3rd Gen Xeon Scalable family), and this part number should be matched against Lenovo's official compatibility and configuration guides for the SR630 V2 before ordering — processor options for CTO servers are chassis-specific and not interchangeable across generations. Verify your SR630 V2 system board revision and firmware level support the 6336Y prior to procurement. For Lenovo ThinkSystem servers and related compute infrastructure, confirm the full bill of materials including memory, storage backplane, and power supply configuration against the SR630 V2 rack server spec matrix.

In network video recorder and VMS server applications, the 6336Y's 24 cores and 48 threads support high-channel-count deployments. Pairing this platform with a purpose-built video surveillance software stack and appropriate NVMe or SAS storage backplane will determine practical camera capacity more than the CPU spec alone — ensure your network switching infrastructure and storage I/O are sized to match this CPU tier.

The 4XG7A63439 slots into the SR630 V2's CTO configuration matrix at a specific tier most buyers will choose when they need to push past 20 cores without moving to a second socket — the 6336Y's 24-core / 48-thread layout at 185W is a deliberate tradeoff between per-socket compute density and thermal headroom in a 1U chassis.

Technical Highlights:

• Asymmetric Core Boost (8 @ 2.5 GHz / 16 @ 2.2 GHz): The priority-core split means OS schedulers that respect Intel's Thread Director hints (Windows 11 / Linux 5.18+ with HFI support) will automatically route latency-sensitive threads to the 2.5 GHz cores. In a VMS context, event processing and alarm handling get the faster cores; background encode streams stay on the standard tier.
• 36 MB L3 Cache: For in-memory workloads — NVR index caches, in-database video metadata queries, or containerized analytics pipelines — 36 MB of last-level cache reduces DRAM pressure noticeably versus the 6334 (16MB) or 6338 (48MB at higher cost). The 6336Y sits in the middle of the Gold 6300 stack on cache density.
• 11.2 GT/s UPI at LGA 4189: In a dual-socket SR630 V2 build, the 11.2 GT/s UPI link is the cross-socket bandwidth ceiling. Memory-bandwidth-intensive analytics inference that needs to pull frame data from the remote NUMA node will hit this ceiling before saturating per-socket memory controllers — factor this into NUMA-aware VM placement if running analytics workloads.

Deployment Considerations:

• At 185W TDP, the SR630 V2 PSU configuration needs to be sized explicitly — do not assume a base single-PSU configuration covers dual-socket 185W + 185W plus memory, storage, and PCIe load. Use Lenovo's online power configurator to validate before ordering.
• The 6336Y uses 10 nm Ice Lake-SP microarchitecture, which added AVX-512 VNNI support relevant to AI inference acceleration. If your VMS or analytics platform uses Intel OpenVINO or oneDNN paths, confirm the software stack is compiled to take advantage of VNNI before benchmarking against prior-gen Cascade Lake deployments.

This processor option is the right call for a high-density 1U VMS server build — specifically a ThinkSystem SR630 V2 deployed as a multi-tenant recording and analytics host in a mid-to-large enterprise security operations environment where 24 cores per socket handles concurrent stream processing without forcing a dual-socket power budget.
