Lenovo 4XG7A63452 SR650 V2 Gold 6346 16C 205W 3.1GHZ

Lenovo 4XG7A63452 Intel Xeon Gold 6346 16-Core Processor for ThinkSystem SR650 V2

Overview

The Lenovo 4XG7A63452 is a factory-configured Intel Xeon Gold 6346 processor option for the ThinkSystem SR650 V2 rack server — a 16-core, 32-thread Ice Lake CPU running at 3.1 GHz base with a 3.6 GHz boost frequency. At 205W TDP, this is a high-performance compute option suited to memory-intensive workloads and parallel processing tasks where core density and clock headroom both matter. If you're provisioning SR650 V2 nodes for VMS analytics servers, AI-inference edge compute, or dense virtualization stacks, the 6346's 36MB L3 cache and 11.2 GT/s system bus rate give it headroom that lower-tier Xeon Silver options lack.

This SKU is an OEM-qualified option for the Lenovo Lenovo server and compute catalog, supplied through channel distribution as a factory-new component. Sourced direct from TD Synnex distribution — no grey-market, no parallel imports.

Key Features

• 16 Cores / 32 Threads (Ice Lake, 10nm): The 3rd Generation Intel Xeon Scalable architecture on 10nm delivers better instructions-per-clock than the prior Cascade Lake generation. For NVR and VMS server workloads running simultaneous decode, analytics, and recording streams, the 32-thread count means fewer bottlenecks when channel counts scale past 64.
• 3.1 GHz Base / 3.6 GHz Boost: The 500 MHz boost headroom matters in single-threaded burst tasks — license plate recognition inference, motion detection event spikes — where base clock undersells actual throughput. Sustained all-core workloads stay closer to the 3.1 GHz base.
• 36MB L3 Cache: A 36MB last-level cache reduces main-memory round trips on working sets that fit — relevant for database-backed VMS platforms and video analytics pipelines that repeatedly access the same frame buffers or index structures.
• 205W Thermal Design Power: At 205W TDP, this processor requires a server platform designed for high-TDP Xeon Gold population. The SR650 V2's cooling and power delivery are rated for this — but factor 205W per socket into your rack power budget and UPS sizing. A dual-socket SR650 V2 with two 6346 processors approaches 410W in processor draw alone before storage, DIMMs, and NICs.
• 11.2 GT/s System Bus Rate: The higher UPI (Ultra Path Interconnect) speed benefits dual-socket configurations where NUMA node communication is frequent — relevant in scale-up analytics or virtualization hosts where vCPUs span sockets.
• 6TB Maximum Memory Support: The 6346 supports up to 6TB of RAM per socket via the LGA 4189 platform's 8-channel DDR4 memory controller — meaningful for in-memory database workloads or large VMS index caches. Actual populated capacity depends on SR650 V2 DIMM slot configuration.
• LGA 4189 Socket (Ice Lake SP): Confirms physical and platform compatibility with the ThinkSystem SR650 V2 motherboard. This is a qualified OEM option — not a retail tray CPU — so it includes Lenovo firmware validation for that platform.
• 64-bit / 32-Thread Execution: Full x86-64 with AVX-512 support (standard on Ice Lake Xeon) enables accelerated workloads in video codec processing, ML inference frameworks, and cryptographic operations relevant to secure video infrastructure.

Integration and Compatibility

The 4XG7A63452 is qualified for the Lenovo ThinkSystem SR650 V2 rack server platform. Deployment in any other chassis is not supported by this SKU. The LGA 4189 socket is exclusive to 3rd Gen Xeon Scalable (Ice Lake SP) — it is not backward-compatible with Cascade Lake (2nd Gen) or forward-compatible with Sapphire Rapids (4th Gen) platforms. Verify your SR650 V2 firmware is updated to a version that supports Ice Lake population before installation; Lenovo publishes XCC and UEFI firmware bundles for this via their support portal. For mixed-CPU dual-socket configurations, Intel and Lenovo require matched stepping and TDP pairing — consult the SR650 V2 product guide before mixing processor SKUs. For environments running video management software on bare metal or hypervisor, confirm your VMS vendor's hardware compatibility list includes SR650 V2 with Ice Lake CPU population.

Frequently Asked Questions

Q: What server is the Lenovo 4XG7A63452 compatible with?

A: The 4XG7A63452 is a qualified processor option for the Lenovo ThinkSystem SR650 V2. It uses the LGA 4189 socket and is specific to 3rd Generation Intel Xeon Scalable (Ice Lake SP) platforms. It is not compatible with earlier SR650 (V1) or other Lenovo server chassis without explicit Lenovo qualification.

Q: What is the base and boost clock speed of the Xeon Gold 6346?

A: The Intel Xeon Gold 6346 runs at 3.1 GHz base frequency with a boost frequency of 3.6 GHz. It has 16 cores and 32 threads.

Q: What is the TDP of the Xeon Gold 6346, and what does that mean for power planning?

A: The Xeon Gold 6346 has a 205W TDP. For a dual-socket SR650 V2 configuration, processor draw alone can reach approximately 410W. Budget accordingly for PDU, UPS, and rack cooling capacity before deploying high-density compute nodes.

Q: How much memory does the Xeon Gold 6346 support?

A: The processor supports up to 6TB of RAM per socket via its 8-channel DDR4 memory controller on the LGA 4189 platform. Actual usable memory depends on DIMM population in the SR650 V2 chassis.

Q: Can the 4XG7A63452 be installed in a dual-socket SR650 V2 configuration?

A: Yes, the SR650 V2 supports dual-socket population. For dual-CPU configurations, Intel and Lenovo require matched processor stepping and TDP. Consult the SR650 V2 product guide to confirm pairing requirements before ordering a second processor.

Q: Is this a retail tray CPU or an OEM-qualified option?

A: This is an OEM-qualified processor option sourced through Lenovo's distribution channel. It includes Lenovo firmware validation for the SR650 V2 platform, which a retail tray CPU does not.

Ted Perry

The 4XG7A63452 is the processor SKU I recommend when a customer is building out an SR650 V2 node for high-channel VMS or AI-inference workloads and needs clock speed alongside core count — the Gold 6346's 3.6 GHz boost and 36MB L3 cache put it ahead of the entry Silver options for latency-sensitive analytics tasks without stepping into the Gold 6354 or 6338 territory where power draw starts dictating your rack layout.

Technical Highlights:

• 205W TDP at 16 Cores: This is the spec that dictates your infrastructure planning more than anything else. At 205W per socket, a dual-populated SR650 V2 draws roughly 410W from processors alone — confirm your circuit capacity and UPS runtime before sizing the node count.
• 36MB L3 Cache / 11.2 GT/s UPI: The cache depth reduces DRAM pressure on working sets that stay within 36MB — relevant for video index structures and frame metadata caches. The 11.2 GT/s UPI link matters specifically in dual-socket deployments where inter-socket NUMA traffic is high.
• 6TB Max Memory per Socket: Few workloads hit this ceiling, but for in-memory VMS databases or large-scale virtualization hosts consolidating many VMs, knowing the ceiling is 6TB per socket (8-channel DDR4) means the platform won't be the bottleneck.

Deployment Considerations:

• Verify SR650 V2 XCC and UEFI firmware support for Ice Lake SP population before installation — Lenovo has published specific firmware bundles for 3rd Gen Xeon Scalable; running outdated firmware on a V2 chassis with an Ice Lake CPU can cause POST failures or reduced feature support.
• This is an OEM-qualified SKU, not a retail tray. Mixing it with a retail-boxed Intel Xeon 6346 in a dual-socket configuration is unsupported by Lenovo — both sockets should use Lenovo-qualified processor options to maintain platform warranty and firmware compatibility.

The right deployment for this processor is an SR650 V2 node serving as a dedicated VMS analytics or AI-inference host — specifically environments running 64+ camera channels with on-server motion analytics, or virtualization hosts where per-socket core count and clock speed both factor into VM density targets.
