Lenovo 4XG7A63454 SR650 V2 Gold 5320T 20C 150W 2.3GHZ

Lenovo 4XG7A63454 Intel Xeon Gold 5320T 20-Core Processor for ThinkSystem SR650 V2

Overview

The Lenovo 4XG7A63454 is a factory-new Intel Xeon Gold 5320T processor option for the ThinkSystem SR650 V2 rack server, built on the 3rd Generation Intel Xeon Scalable platform. The 5320T delivers 20 cores at a 2.3 GHz base frequency with a 150W thermal envelope — a deliberate balance between multi-threaded throughput and power efficiency that makes it a practical fit for dense two-socket configurations where power draw and cooling headroom matter as much as raw clock speed.

This processor belongs to the Intel Xeon Gold 5000 series, which occupies the mid-tier of the Xeon Scalable family — capable enough for demanding enterprise workloads without the premium cost of the Platinum tier. The LGA 4189 socket paired with the SR650 V2 platform gives you access to the full feature set of the Ice Lake-SP architecture, including per-core performance tiering that separates high-priority compute from background thread workloads.

Key Features

• 20 Cores / 40 Threads at 150W TDP: The 5320T packs 20 physical cores with Hyper-Threading into a 150W power budget. For a two-socket SR650 V2, that translates to 40 cores and 80 threads per chassis — meaningful density for virtualized environments where per-VM overhead accumulates fast.
• 2.3 GHz Base / 3.5 GHz Boost: The 2.3 GHz base keeps sustained all-core power consumption predictable. When workloads demand it, single-thread boost reaches 3.5 GHz — a 52% frequency uplift that benefits latency-sensitive applications like database query execution or real-time analytics.
• Per-Core Frequency Tiering (6 High / 14 Low Priority): The 5320T uses Intel's Thermal Velocity Boost architecture with 6 high-priority cores running at 2.6 GHz and 14 low-priority cores at 2.1 GHz. In practice, OS and hypervisor schedulers can steer critical threads to the high-priority cores, reducing jitter in mixed workload environments without requiring manual NUMA tuning.
• 30 MB L3 Cache: A 30 MB last-level cache reduces main-memory round-trips for working datasets that fit within that window. For in-memory databases, caching layers, or surveillance analytics engines processing multiple streams simultaneously, this cache footprint is a direct contributor to sustained throughput.
• 11.2 GT/s System Bus: The UPI interconnect at 11.2 GT/s ensures low-latency data transfer between sockets in a two-processor SR650 V2 configuration. NUMA-aware workloads benefit directly — memory access across sockets stays fast enough that cross-NUMA penalties are manageable without aggressive workload pinning.
• 64-bit / 10nm Ice Lake-SP Architecture: Built on Intel's 10nm process, the Ice Lake-SP generation improves instructions-per-clock compared to the prior Cascade Lake platform. This matters for compute-bound workloads — more work per clock cycle means the 2.3 GHz base punches above its frequency number in real applications.
• LGA 4189 Socket Compatibility: The LGA 4189 socket is native to the SR650 V2 platform. This processor drops directly into SR650 V2 configurations without platform adapters or BIOS exceptions, simplifying procurement and sparing for data center teams managing homogeneous server fleets.

Integration and Compatibility

The 4XG7A63454 is a Lenovo-qualified processor option for the ThinkSystem SR650 V2, meaning it has passed Lenovo's platform validation testing for that specific server SKU. In multi-processor configurations, both sockets must be populated with identical processor models to avoid asymmetric NUMA topologies that complicate workload scheduling. Verify your SR650 V2 system board revision and firmware level before installing — Lenovo's compatibility matrix for the SR650 V2 ties certain processor options to minimum XClarity Controller firmware versions. The 150W TDP positions this processor as compatible with standard SR650 V2 cooling configurations, but confirm your specific chassis cooling option (standard vs. high-performance fan) against Intel's thermal specifications for the 5320T if the deployment environment runs at elevated ambient temperatures.

For security and surveillance applications — including network video recorders and edge analytics servers — the 5320T's 20-core topology handles concurrent stream decoding and analytics inference workloads that single-socket entry-class processors cannot sustain. If you're evaluating rack servers for a VMS back-end or AI-inference node, the SR650 V2 with this processor handles Milestone XProtect or Genetec workloads at scale.

Pair this server platform with a properly sized network switch to ensure sufficient uplink bandwidth when aggregating high-bitrate camera streams.

Frequently Asked Questions

Q: What server platform is the 4XG7A63454 designed for?

A: The 4XG7A63454 is a processor option qualified for the Lenovo ThinkSystem SR650 V2 rack server. It uses the LGA 4189 socket, which is native to the SR650 V2 platform.

Q: How many cores and threads does the Xeon Gold 5320T provide?

A: The Intel Xeon Gold 5320T delivers 20 physical cores with Hyper-Threading enabled, providing 40 logical threads per processor. In a dual-socket SR650 V2 configuration, that scales to 40 cores and 80 threads per chassis.

Q: What is the TDP and base frequency of the 5320T?

Q: Does the 5320T support per-core frequency tiering?

A: Yes. The 5320T uses a split-core design with 6 high-priority cores at 2.6 GHz and 14 low-priority cores at 2.1 GHz. This allows OS and hypervisor schedulers to direct latency-sensitive threads to the faster cores automatically.

Q: What Intel processor generation is the 5320T?

A: The 5320T is part of the 3rd Generation Intel Xeon Scalable family (Ice Lake-SP), built on a 10nm process node. It belongs to the Intel Xeon Gold 5000 series.

Q: Can the 4XG7A63454 be used in a dual-processor configuration?

A: The SR650 V2 supports two-processor configurations. If populating both sockets, both processors must be identical models. The 11.2 GT/s UPI interconnect handles cross-socket communication in dual-processor setups.

The 4XG7A63454 is one of those processor options that makes sense when you look at the full power-per-core math rather than headline clock speed. The 5320T's 150W TDP across 20 cores works out to 7.5W per core — notably efficient for a Gold-class part, and that matters when you're planning a dense SR650 V2 deployment where rack PDU capacity is a real constraint.

Technical Highlights:

• Boost to 3.5 GHz: The 1.2 GHz gap between base (2.3 GHz) and boost (3.5 GHz) is wider than typical for a 150W part, giving the scheduler real headroom for bursty workloads without sustained power draw at peak.
• 30 MB L3 Cache: At 1.5 MB per core, the cache-to-core ratio is solid for server workloads involving large in-memory datasets — surveillance analytics or database query caches that stay within 30 MB see meaningfully fewer DRAM accesses.
• 11.2 GT/s UPI Interconnect: In a two-socket build, this bus rate keeps cross-NUMA latency low enough that NUMA-unaware applications don't pay a steep penalty — useful when deploying VMS software that wasn't written with strict NUMA affinity in mind.

Deployment Considerations:

• Confirm your SR650 V2 firmware revision before installation — Lenovo ties specific processor options to minimum XClarity Controller versions, and a mismatch can prevent POST without a clear error message.
• The T-suffix on the 5320T indicates optimized power consumption; verify your specific SR650 V2 cooling configuration (standard vs. high-performance fans) against the 150W envelope if the deployment runs at ambient temperatures above 35°C.

This processor is well-suited for SR650 V2 deployments serving as back-end VMS servers in mid-to-large surveillance installations — environments where you need 20+ cores for concurrent stream handling and analytics inference, but where rack power density makes a 205W Platinum-tier part impractical to deploy at scale.
