Lenovo 4XG7A63468 SR650 V2 Silver 4310 12C 120W 2.1GHZ

Lenovo 4XG7A63468 Intel Xeon Silver 4310 12-Core Processor for ThinkSystem SR650 V2

Overview

The Lenovo 4XG7A63468 is a factory-configured Intel Xeon Silver 4310 processor option for the ThinkSystem SR650 V2 rack server — a 12-core, 24-thread CPU running at 2.1 GHz base with a 3.3 GHz boost clock, delivered as a tray-packaged component sourced through Lenovo's server channel. If you're speccing or expanding an SR650 V2 deployment and need a mid-range Xeon Scalable processor that balances core density with a controlled 120W TDP, this is the part to evaluate. It is not a standalone system — it installs into the LGA 4189 socket on a compatible SR650 V2 motherboard.

The 4310 belongs to Intel's 3rd Generation Xeon Scalable family (Ice Lake-SP), fabricated on a 10 nm process node. That generation brought meaningful per-core IPC improvements over the prior Cascade Lake generation, which matters when workloads can't scale linearly across all 12 cores — single-threaded segments of video analytics pipelines, VMS server services, and database engines all benefit from higher per-clock throughput, not just raw core count.

Key Features

• 12 Cores / 24 Threads at 2.1 GHz Base: Twenty-four logical processors give the SR650 V2 enough concurrency to handle mixed workloads — simultaneous video stream decoding, metadata indexing, and management-plane services — without a second socket. The 3.3 GHz boost frequency picks up slack when thread saturation drops, so latency-sensitive queries don't stall waiting for a free core.
• 18 MB Intel Smart Cache: The on-die cache is large enough to hold active working sets for dozens of concurrent lightweight threads. In practice this reduces main-memory round trips on access-control event logging, alarm correlation, and similar low-latency tasks that would otherwise thrash L3 under smaller cache designs.
• 120W Thermal Design Power: At 120W TDP, this processor fits within the SR650 V2's standard thermal envelope without requiring upgraded cooling beyond the server's baseline configuration. Rack planners working with tight per-U power budgets will find this more manageable than the 150W or 165W options in the same Xeon Silver / Gold family — note, however, that no cooler is included with this tray package; the SR650 V2 chassis supplies its own heat sink assembly.
• 10.4 GT/s System Bus: The UPI (Ultra Path Interconnect) speed governs how fast this processor communicates with memory controllers, I/O, and — in dual-socket configurations — the second CPU. At 10.4 GT/s, memory-bandwidth-hungry workloads like high-resolution video transcoding and large-dataset analytics see less interconnect bottleneck than earlier-generation 9.6 GT/s parts.
• LGA 4189 Socket (Ice Lake-SP Platform): This socket is exclusive to 3rd Gen Xeon Scalable. If you're replacing or augmenting a processor in an existing SR650 V2, verify the board revision supports 4310 — not all early SR650 V2 UEFI releases supported the full Ice Lake-SP lineup at launch; confirm firmware is current before installation.
• 64-Bit Operating Mode, 10 nm Lithography: The 10 nm node translates to better performance-per-watt relative to the 14 nm Cascade Lake predecessor — useful when you're comparing processor options across a multi-node deployment where aggregate rack power and cooling costs compound.
• Tray Package — No Cooler Included: This is a component-level part, not a boxed retail processor. The SR650 V2 supplies the heat sink; the tray format is standard for OEM server deployments. Do not order this expecting a standalone cooler in the box.

Integration and Compatibility

The 4XG7A63468 is a Lenovo-qualified processor option for the ThinkSystem SR650 V2 platform. Installation into non-Lenovo systems or SR650 V2 variants outside Lenovo's compatibility matrix is not supported by the evidence available — cross-reference Lenovo's ServerProven database or the SR650 V2 product guide before ordering for any configuration not explicitly listed. The SR650 V2 supports up to two Xeon Scalable processors in its dual-socket design; this part can serve as either the primary or secondary CPU in that configuration. Memory, storage, networking, and GPU options are separate line items and are not included.

For server components and processor upgrades in the Lenovo server catalog, confirm your existing SR650 V2 firmware revision and heat-sink compatibility before provisioning. Administrators deploying this CPU in a video surveillance or physical security server context should also review network video recorder platform requirements and server storage options to complete the build.

Frequently Asked Questions

Q: Is the 4XG7A63468 a complete server or just a processor?

A: It is a processor component only — specifically the Intel Xeon Silver 4310 in tray format for installation in a Lenovo ThinkSystem SR650 V2 server. No server chassis, memory, storage, or cooler is included.

Q: Does this processor include a heat sink or cooling solution?

A: No. The 4XG7A63468 is a tray-packaged CPU with no cooler included. The ThinkSystem SR650 V2 chassis provides its own heat sink assembly; verify the correct heat sink part number for your SR650 V2 configuration separately.

Q: What is the base and boost clock speed of the 4310 processor?

A: The Intel Xeon Silver 4310 runs at 2.1 GHz base frequency with a boost clock of up to 3.3 GHz across its 12 cores and 24 threads.

Q: Can this processor be used in servers other than the Lenovo ThinkSystem SR650 V2?

A: The 4XG7A63468 is a Lenovo-qualified component for the SR650 V2. While the underlying Intel Xeon Silver 4310 uses the LGA 4189 socket shared across other Ice Lake-SP platforms, Lenovo OEM parts carry Lenovo's qualification matrix. Use in non-Lenovo or non-SR650 V2 systems falls outside verified compatibility.

Q: What generation of Intel Xeon is the 4310?

A: The 4310 is part of Intel's 3rd Generation Xeon Scalable family (Ice Lake-SP), built on a 10 nm process node — one generation newer than the Cascade Lake (2nd Gen) parts it succeeds in the SR650 V2 lineup.

Q: What is the TDP and how does it affect rack planning?

A: The 4310 has a 120W Thermal Design Power. This fits within the SR650 V2's standard thermal configuration. For rack planners, 120W is on the lower end of the Xeon Silver/Gold range, making power budget calculations more predictable in dense multi-server deployments.

Ted Perry

When I look at the 4XG7A63468 for a physical security server build, the spec that stands out immediately is the 120W TDP paired with 12 cores at 2.1 GHz base — that combination tells you this is a processor optimized for sustained, multi-threaded workloads rather than peak burst performance. For a VMS host running 40–80 camera streams with concurrent analytics, sustained throughput at a controlled power draw beats a higher-clocked 8-core part that thermally throttles under load.

Technical Highlights:

• 3.3 GHz Boost Clock: Latency-sensitive VMS operations — alarm event processing, live-view stream switching, operator query responses — benefit from the boost frequency headroom when the full 12-core load drops. You get responsive operator experience without paying for a Gold-tier processor.
• 18 MB Smart Cache: Large enough to keep active decode contexts in cache for a meaningful number of concurrent streams. Fewer L3 misses means the memory subsystem isn't the bottleneck during peak recording windows — relevant when you're running high-bitrate H.265 streams from a large camera count.
• 10 nm Ice Lake-SP Architecture: The per-core IPC improvement over Cascade Lake is real and measurable in workloads with mixed parallelism. Video analytics engines that serialize portions of their pipeline will execute those segments faster than on an equivalently-clocked 14 nm predecessor.

Deployment Considerations:

• This is a tray CPU — no cooler ships with it. The SR650 V2 heat sink assembly is a separate Lenovo part number. Confirm you have the correct heat sink for your chassis airflow configuration (performance vs. standard) before scheduling the installation window.
• Verify SR650 V2 UEFI firmware version before installing; early SR650 V2 BIOS releases did not support the full 3rd Gen Xeon Scalable lineup. A firmware mismatch will either prevent POST or silently reduce processor capabilities — check Lenovo's firmware matrix against your current UEFI build.

This processor is a strong fit for a mid-density VMS host where you're running a single SR650 V2 node for a 40–100 camera deployment and want predictable power consumption without stepping up to Xeon Gold pricing. It is not the right pick if your analytics workload saturates 12 cores and demands the additional cores or memory bandwidth of a Gold 5300-series part.
