Lenovo 4XG7A72935 Xeon Gold 6354 18-Core Processor for ThinkSystem ST650 V2

Overview

The Lenovo 4XG7A72935 is a factory-configured Intel Xeon Gold 6354 processor option for the ThinkSystem ST650 V2 tower server — an 18-core, 36-thread compute module designed for workloads that need sustained multi-threaded throughput without moving to a rack chassis. Running at a 3.0 GHz base with a 3.6 GHz boost, this 3rd Generation Intel Xeon Scalable part targets mid-range enterprise compute: database servers, virtualization hosts, simulation workloads, and edge analytics nodes where core density and clock speed both matter. If you're building or expanding an ST650 V2 deployment and need to specify the processor option, this is the part number to order.

Key Features

• 18 Cores / 36 Threads (Intel Xeon Gold 6354): Thirty-six logical processors under a hypervisor means more VMs per socket before you hit scheduling contention. For a Hyper-V or VMware ESXi host running mixed workloads, this core count gives you meaningful headroom without stepping up to a higher-TDP Platinum SKU.
• 3.0 GHz Base / 3.6 GHz Boost: The 600 MHz spread between base and boost is useful for workloads with burst-intensive operations — a database query optimizer or a compile job hits 3.6 GHz on demand, while steady-state background tasks settle at base. You get responsiveness without paying for sustained all-core boost power draw.
• Heterogeneous Core Configuration (8 High-Priority + 10 Standard): The 6354 implements Intel's core classification — 8 cores run at 3.1 GHz high-priority frequency and 10 run at 2.8 GHz standard frequency. Thread schedulers that are core-aware (Windows Server 2019+, recent Linux kernels) can route latency-sensitive processes to the faster cores automatically, which matters for mixed OLTP and reporting workloads sharing the same socket.
• 39 MB L3 Cache: Nearly 40 MB of last-level cache per socket reduces DRAM latency for working sets that fit — in-memory analytics, hot database indexes, and frequently accessed VM page tables all benefit. Fewer cache misses translate directly to lower average query latency under concurrent load.
• 205W TDP: This is a full-envelope Xeon Gold, not a binned low-power variant. Plan your ST650 V2 power budget and cooling accordingly — the tower chassis is rated for this TDP, but shared rack PDU circuits with multiple units need to account for it. Don't deploy this alongside a low-power config assumption.
• LGA 4189 Socket / 10nm Lithography: The LGA 4189 platform (Ice Lake-SP) supports up to 8-channel DDR4-3200 memory per socket and PCIe 4.0 connectivity — both of which are relevant if you're pairing storage-heavy or GPU-accelerated workloads with this processor in the ST650 V2 chassis. The 10nm node also improves instructions-per-clock over the previous generation.
• 11.2 GT/s System Bus Rate: Higher interconnect bandwidth means less bottleneck moving data between the processor and memory subsystem under parallel I/O — relevant for NVMe storage arrays and high-bandwidth networking cards installed in the ST650 V2's PCIe slots.
• 64-bit Operating Mode: Full 64-bit execution support is a baseline requirement for any modern server OS and hypervisor. Combined with the platform's large memory addressing capability, there's no architectural ceiling on addressable RAM for memory-intensive applications.

Integration & Compatibility

The 4XG7A72935 is a Lenovo-configured option for the Lenovo ThinkSystem ST650 V2 platform. It occupies the LGA 4189 socket and is compatible with the 3rd Generation Intel Xeon Scalable processor family supported by that chassis. Verify your ST650 V2 firmware level before installing — Lenovo publishes UEFI/BMC update requirements for Ice Lake-SP processors, and running an outdated firmware can prevent POST. This processor pairs with DDR4-3200 RDIMMs or LRDIMMs across the ST650 V2's memory slots; maximizing memory bandwidth requires populating channels symmetrically. For integrators deploying the ST650 V2 as a tower server in a branch office or edge location, the 18-core count keeps the unit viable for several years of VM consolidation growth without a platform refresh. If you're evaluating processor options for network-intensive workloads or storage server builds, cross-reference the ST650 V2 configuration guide for thermal and power supply pairing requirements at 205W TDP.

The 4XG7A72935 is worth a close look when you're speccing an ST650 V2 for a workload that sits between entry-level virtualization and full rack-mount scale-out. The Xeon Gold 6354's 18-core / 36-thread configuration at 3.0 GHz base gives you a lot of per-socket compute for a tower form factor — and the 39 MB L3 cache is meaningful for database servers where hot working sets stay in cache and avoid the latency hit of going to DRAM.

Technical Highlights:

• Heterogeneous Core Frequencies: The 8 high-priority cores at 3.1 GHz and 10 standard cores at 2.8 GHz let modern OS schedulers route latency-sensitive threads automatically — this is a real benefit for mixed OLTP + reporting workloads sharing one socket.
• 3.6 GHz Max Boost: That 600 MHz headroom above base means burst-heavy jobs (compile, ETL, query optimization) get clock speed on demand without you having to over-provision for sustained peak.
• 205W TDP: This is not a low-power bin — at 205W, the ST650 V2 power supply and airflow path need to be configured for full load. Don't assume a shared circuit that was sized for a lower-TDP config will hold under peak draw.

Deployment Considerations:

• Verify ST650 V2 UEFI and BMC firmware revisions before installing — Lenovo has specific firmware prerequisites for Ice Lake-SP (LGA 4189) processors, and skipping this step can cause POST failures on otherwise healthy hardware.
• To get full benefit from the 11.2 GT/s system bus and DDR4-3200 support, populate memory channels symmetrically; asymmetric DIMM configurations will reduce effective bandwidth and undercut the processor's throughput advantage.

This processor option is a strong fit for branch office or edge IT consolidation builds where the ST650 V2 tower form factor is the right physical footprint — specifically for VMware or Hyper-V hosts running 20–40 VMs that need predictable per-VM core allocation and enough cache to keep hot database indexes off disk.
