Lenovo 4XG7A72934 Intel Xeon Platinum 8352V 36-Core Server Processor

Overview

The Lenovo 4XG7A72934 is a factory-configured Intel Xeon Platinum 8352V processor option for the ThinkSystem ST650 V2 server, delivering 36 cores and 72 threads on Intel's 3rd Generation Xeon Scalable (Ice Lake) architecture. At a 2.1 GHz base clock with a 3.5 GHz boost frequency and 54 MB of L3 cache, this processor is built for compute-dense enterprise workloads — virtualization hosts, data analytics pipelines, and multi-threaded simulation environments where per-core throughput and memory bandwidth both matter. If you are configuring or upgrading a Lenovo server platform and need a processor that balances high core count with manageable power delivery, the 4XG7A72934 positions the ST650 V2 as a serious contender in the 2-socket enterprise segment.

Key Features

• 36 Cores / 72 Threads (Ice Lake): Intel's 10 nm Ice Lake microarchitecture delivers improved IPC over prior Cascade Lake generations. In practice, that means more virtual machines per socket on VMware or Hyper-V, or faster batch processing in analytics workloads — without requiring a third server in the rack to hit the same throughput.
• 2.1 GHz Base / 3.5 GHz Turbo Boost: The 1.4 GHz headroom between base and boost lets the processor respond to bursty single-threaded or lightly-threaded workloads — database query spikes, for example — without sacrificing sustained all-core throughput on background jobs running in parallel.
• 54 MB L3 Cache: Larger cache reduces main-memory round trips on working sets that fit within it. For in-memory databases or caching layers (Redis, Memcached), this translates directly to lower latency and higher query throughput before hitting DRAM bandwidth limits.
• 195 W Thermal Design Power: At 195 W TDP, power delivery and cooling budgeting matter. The ST650 V2 is engineered to handle this thermal envelope, but rack-level PDU planning and airflow pathing should be confirmed before provisioning — particularly in high-density deployments where multiple compute nodes share a UPS segment.
• 72 Hardware Threads via Hyper-Threading: The 36-core / 72-thread configuration means the OS scheduler sees 72 logical processors. Under mixed workloads — concurrent VMs each running multi-threaded services — this typically yields 15–25% additional throughput compared to 36-thread operation, depending on memory access patterns.
• 11.2 GT/s System Bus: The UPI (Ultra Path Interconnect) link at 11.2 GT/s is the data highway between sockets in a 2-socket ST650 V2 configuration. Higher bus throughput reduces inter-socket latency for workloads that share data across NUMA nodes — relevant for distributed in-memory computing and HPC scenarios.
• LGA 4189 Socket — ST650 V2 Platform: This processor is designed for the LGA 4189 socket found in the ThinkSystem ST650 V2. It is not a universal drop-in; platform compatibility with the ST650 V2 is the scope. Verify firmware and BIOS version support on your specific chassis before ordering a processor upgrade into an existing system.
• 64-Bit Operating Mode: Full 64-bit instruction set support means no OS or hypervisor constraints from the processor side. VMware ESXi, RHEL, Windows Server, and all modern enterprise Linux distributions run without compatibility caveats.
• Intel Xeon Platinum 8000 Series Tier: The Platinum designation within the Xeon Scalable line signals support for advanced RAS (Reliability, Availability, Serviceability) features — machine check architecture improvements, enhanced error correction, and platform-level instrumentation — that matter in always-on production environments.

Integration and Compatibility

The 4XG7A72934 is a Lenovo-sourced component configured for the ThinkSystem ST650 V2 server platform and the LGA 4189 socket. Pairing this processor with appropriate DDR4 memory (verify channel count and speed support against the ST650 V2 configuration guide) is critical to realizing full memory bandwidth. For enterprise virtualization deployments, this processor pairs naturally with high-capacity NVMe or SAS storage configurations and enterprise networking that can sustain the I/O throughput 72 active threads can generate. Workload profiling before deployment is recommended — if your application is not multi-threaded at scale, a lower-core-count, higher-frequency Xeon Platinum variant may deliver better single-job latency at lower TDP.

Frequently Asked Questions

Q: What server platform is the Lenovo 4XG7A72934 designed for?

A: The 4XG7A72934 is a processor option designed for the Lenovo ThinkSystem ST650 V2 server, using the LGA 4189 socket. It is not a standalone retail processor and is intended for use within that specific server platform.

Q: What is the core and thread count on the 4XG7A72934?

A: The Intel Xeon Platinum 8352V in the 4XG7A72934 provides 36 physical cores and 72 threads via Intel Hyper-Threading, operating at a 2.1 GHz base frequency with a 3.5 GHz boost frequency.

Q: What is the TDP of the 8352V processor in this configuration?

A: The Thermal Design Power (TDP) is 195 W. Rack power budgeting, PDU capacity, and server cooling airflow should all be validated against this figure before deployment, particularly in high-density environments.

Q: What processor generation and codename does the 4XG7A72934 use?

A: This is a 3rd Generation Intel Xeon Scalable processor, codenamed Ice Lake, built on Intel's 10 nm process node. It belongs to the Xeon Platinum 8000 series.

Q: How much L3 cache does the Xeon Platinum 8352V provide?

A: The 8352V includes 54 MB of L3 cache, which reduces main-memory latency for workloads with working sets that fit within the cache — beneficial for in-memory databases and analytics engines.

Q: Is the 4XG7A72934 compatible with other Lenovo server platforms beyond the ST650 V2?

A: Based on available evidence, this processor option is configured for the ThinkSystem ST650 V2. Compatibility with other LGA 4189 platforms should be confirmed against Lenovo's official configuration guides for each platform before installation.

Ted Perry

The 4XG7A72934 puts the Intel Xeon Platinum 8352V — 36 cores, 72 threads, 54 MB cache, 195 W TDP — inside a Lenovo ThinkSystem ST650 V2 chassis. That 3.5 GHz turbo headroom on top of a 2.1 GHz base is the number I focus on when evaluating this configuration for mixed enterprise workloads: it means the processor can sprint on latency-sensitive operations without being throttled during sustained multi-threaded batch runs.

Technical Highlights:

• 36 Cores / 72 Threads: On a VMware ESXi host, 72 logical processors give the scheduler real room to pack VMs. A conservatively overcommitted 4:1 vCPU-to-pCPU ratio still leaves capacity headroom — this is a dense consolidation processor, not a specialty single-workload chip.
• 54 MB L3 Cache: For analytics or database workloads where the hot dataset fits in cache, 54 MB cuts DRAM round trips meaningfully. In Redis or similar in-memory tiers, expect measurably lower tail latency compared to prior-generation Cascade Lake configurations with smaller cache pools.
• 11.2 GT/s UPI Bus: In a 2-socket ST650 V2, this is the backbone for NUMA-crossing data. If your application distributes work across sockets — distributed in-memory grids, parallel simulation — the 11.2 GT/s link keeps inter-socket latency from becoming the bottleneck.

Deployment Considerations:

• At 195 W TDP, confirm that your rack's PDU allocation and the ST650 V2's cooling configuration are rated for sustained full-core load. Thermal throttling under poorly provisioned airflow will erode the throughput advantage this core count provides.
• This is an LGA 4189 component configured for the ST650 V2 — it is not a field-swappable generic CPU. If you are upgrading an existing ST650 V2, verify the system BIOS version supports the 8352V before procurement; a firmware incompatibility will prevent POST.

This configuration is a strong fit for enterprise virtualization hosts or Kubernetes node clusters inside a tower-form-factor deployment — the ST650 V2's tower chassis suits machine rooms or branch data closets where rack space is limited but compute density still matters.
