Lenovo 4XG7A72931 Intel Xeon Platinum 8360Y 36-Core Processor for ThinkSystem ST650 V2

Overview

The Lenovo 4XG7A72931 is an Intel Xeon Platinum 8360Y processor option for the ThinkSystem ST650 V2 tower server. The 8360Y is a 3rd Generation Intel Xeon Scalable part — 36 cores, 72 threads, 2.4 GHz base clock, with a 3.5 GHz max boost — positioned at the high end of the Platinum 8000 series for compute-dense workloads that demand both core count and high single-thread ceiling. At 250W TDP, this is a full-power Platinum SKU, not a low-voltage binned variant, so provisioning your power and cooling infrastructure accordingly is non-negotiable before spec'ing it into a chassis.

The socket is LGA 4189, which is exclusive to Intel's Ice Lake-SP generation and requires a compatible ST650 V2 board revision. Verify your chassis bill-of-materials and firmware level before ordering — LGA 4189 is not backward-compatible with earlier Xeon generations.

Key Features

• 36 Cores / 72 Threads: Enough hardware threads to run dense VM stacks or parallel analytics pipelines without contention — relevant for consolidating multiple workloads onto a single socket in the ST650 V2 tower form factor.
• 2.4 GHz Base / 3.5 GHz Boost: The 1.1 GHz headroom between base and boost means sustained multi-threaded jobs run at 2.4 GHz while bursty single-threaded tasks (database queries, latency-sensitive microservices) ramp to 3.5 GHz automatically.
• High-Priority Core Architecture: 12 of the 36 cores are designated high-priority at 2.7 GHz; the remaining 24 run at 2.1 GHz. This tiered frequency design lets the OS scheduler push latency-sensitive threads to faster cores without manual affinity tuning on supported operating systems.
• 10nm Intel Ice Lake-SP Lithography: The process node improvement over prior-gen Cascade Lake translates to better instructions-per-clock and improved power efficiency at comparable frequencies — meaningful when the socket TDP ceiling is already at 250W.
• 11.2 GT/s System Bus: Higher interconnect bandwidth compared to prior Xeon generations reduces memory and I/O bottlenecks on data-heavy workloads like video analytics, large-dataset inference, or NVR-adjacent storage processing.
• 64-Bit Operating Mode / 72 Threads: Full 64-bit support with 72 simultaneous execution threads allows memory-intensive enterprise applications to address large working sets and parallelize without hitting 32-bit ceiling constraints.

Integration & Compatibility

The 4XG7A72931 is a Lenovo-qualified component for the ThinkSystem ST650 V2 platform. It installs into the LGA 4189 socket and is part of the 3rd Generation Intel Xeon Scalable (Ice Lake-SP) ecosystem, which supports DDR4 memory channels and PCIe 4.0 I/O lanes. Confirm the specific ST650 V2 system board supports dual-socket configurations if deploying in a two-processor chassis layout, as the ST650 V2 is available in both single- and dual-socket board variants. Lenovo's ServerProven compatibility matrix is the authoritative reference for validated memory, NIC, and storage add-in cards for this platform.

Frequently Asked Questions

Q: What server is the Lenovo 4XG7A72931 compatible with?

A: The 4XG7A72931 is a processor option qualified for the Lenovo ThinkSystem ST650 V2 tower server. It uses the LGA 4189 socket and is specific to the 3rd Generation Intel Xeon Scalable (Ice Lake-SP) platform.

Q: What is the TDP of the Intel Xeon Platinum 8360Y in this kit?

A: The Xeon Platinum 8360Y carries a 250W TDP. Ensure your ST650 V2 power supply and cooling configuration are provisioned for this full-power SKU before deployment.

Q: How many cores and threads does the 8360Y provide?

A: The processor delivers 36 cores and 72 threads, with a base frequency of 2.4 GHz and a maximum boost of 3.5 GHz.

Q: What is the high-priority core configuration on the 8360Y?

A: The 8360Y implements a tiered core design: 12 high-priority cores run at 2.7 GHz and 24 standard cores run at 2.1 GHz, allowing the OS scheduler to direct latency-sensitive threads to the faster cores automatically.

Q: Is the LGA 4189 socket compatible with earlier Xeon generations?

A: No. LGA 4189 is exclusive to Intel's 3rd Generation Xeon Scalable (Ice Lake-SP) platform. It is not compatible with prior Xeon generations such as Cascade Lake (LGA 3647).

The 4XG7A72931 drops a 250W Xeon Platinum 8360Y — 36 cores, 72 threads — into the ST650 V2 tower chassis. That is a serious compute commitment in a tower package, and the tiered-core architecture (12 cores at 2.7 GHz, 24 at 2.1 GHz) is the detail most buyers overlook when comparing this SKU against lower-binned Platinum parts with flat frequency profiles.

Technical Highlights:

• 3.5 GHz Max Boost: For a 36-core Platinum SKU, the 3.5 GHz ceiling is notably high — beneficial for mixed workloads where some threads are latency-bound (real-time analytics, database queries) while others are throughput-bound (batch processing, transcoding).
• 11.2 GT/s System Bus: The Ice Lake-SP interconnect speed reduces the memory bandwidth bottleneck that plagued prior-gen Cascade Lake deployments under high thread counts — measurable improvement on workloads that stream large datasets across all 72 threads simultaneously.
• 10nm Ice Lake-SP Lithography: Instructions-per-clock gains over Cascade Lake are real; Intel's internal benchmarks show 20% IPC uplift generation-over-generation — which on a 36-core part translates to meaningful headroom reduction before you hit the 250W TDP ceiling.

Deployment Considerations:

• The ST650 V2 supports both single- and dual-socket configurations — confirm your board variant before ordering a second 4XG7A72931 unit, as the single-socket board physically lacks the second LGA 4189 socket and associated power delivery circuitry.
• At 250W TDP, this processor consumes roughly the same power as two mid-range Platinum SKUs. Size your ST650 V2 PSU and datacenter PDU allocation accordingly — underpowering a 250W CPU under sustained load will cause thermal throttling that negates the boost frequency entirely.

The 4XG7A72931 is best positioned for ST650 V2 deployments running compute-heavy consolidated workloads — think dense VM hosts, real-time video analytics servers, or edge AI inference nodes where you need both high core count and headroom for latency-sensitive burst tasks in a tower chassis footprint.
