Lenovo 4XG7A72952 Intel Xeon Gold 6330 28-Core Server Processor

Overview

The Lenovo 4XG7A72952 is an Intel Xeon Gold 6330 processor option kit engineered for the ThinkSystem ST650 V2 rack server. With 28 cores running at a 2.0 GHz base and boosting to 3.1 GHz, this 3rd Generation Intel Xeon Scalable processor delivers 56 threads of compute headroom — the right choice when you're scaling virtualized workloads, video analytics processing, or large-scale surveillance VMS deployments that demand sustained multi-threaded throughput. As part of the broader Lenovo server and compute catalog, the 4XG7A72952 slots directly into the ST650 V2's LGA 4189 socket, keeping your upgrade path factory-validated and your support chain intact.

Key Features

• 28 Cores / 56 Threads: The Gold 6330's core density handles deep parallelism — think 50+ concurrent camera streams decoding in software, or VM environments where each tenant needs dedicated vCPU allocation without contention. More cores per socket means fewer servers needed to hit the same throughput target.
• 2.0 GHz Base / 3.1 GHz Boost Frequency: The base clock sustains heavy all-core workloads like batch transcoding or analytics inference across a full camera array. The 3.1 GHz boost engages on lightly-threaded tasks — database queries, alert correlation, real-time event processing — where single-thread speed matters. This spread between base and boost is wider than entry Xeon Silver options, giving you more behavioral flexibility under mixed loads.
• Heterogeneous Core Architecture — 12 High-Priority + 16 Efficiency Cores: Intel's 3rd Gen Scalable design splits the 28 cores into 12 high-priority cores at 2.1 GHz and 16 lower-priority cores at 1.8 GHz. Workload scheduling can steer latency-sensitive threads (live video decode, API serving) to the faster cores while background tasks (log ingestion, storage management) land on the efficiency cores — reducing jitter without manual CPU affinity tuning.
• 205W TDP: At 205W thermal design power, this processor sits in the mid-to-upper range of the Gold 6000 series. Confirm your ST650 V2 chassis power supply and cooling configuration supports the 205W envelope before ordering — Lenovo's ST650 V2 thermal documentation governs which processor TDPs are supported in each fan zone configuration. Pair with appropriate rack server infrastructure sized for the thermal load.
• 56 Threads via Hyper-Threading: Two logical threads per physical core means the OS scheduler has 56 execution contexts to dispatch work against. For hypervisor environments (VMware ESXi, Hyper-V), this translates directly into vCPU capacity — you can provision more virtual machines at the same physical core count compared to non-HT processors, improving server consolidation ratios in enterprise security operations centers.
• 11.2 GT/s System Bus Rate: The 11.2 GT/s UPI interconnect rate keeps memory and I/O latency low under sustained workloads. In a server environment running both NVR software and real-time analytics, high interconnect bandwidth reduces the bottleneck between CPU, memory controllers, and PCIe-attached storage or GPU accelerators.
• 10 nm Lithography (Ice Lake-SP): Built on Intel's 10 nm SuperFin process, the Gold 6330 achieves better performance-per-watt than the previous 14 nm Cascade Lake generation. In always-on deployments running 24/7, even modest efficiency improvements compound into meaningful power and cooling cost reductions over a 3–5 year server lifecycle.
• 64-bit Operating Mode: Full 64-bit instruction support ensures compatibility with current server operating systems and workloads — no legacy 32-bit constraints on memory addressing or application compatibility. Combined with the LGA 4189 socket's large memory channel support, this enables configurations with substantial RAM for in-memory caching or analytics model inference.
• LGA 4189 Socket (Ice Lake-SP Platform): The LGA 4189 socket is specific to 3rd Gen Intel Xeon Scalable (Ice Lake-SP) processors. This processor is not backward-compatible with LGA 3647 (Cascade Lake) boards — confirm your ST650 V2 motherboard revision before ordering. Consult the datacenter compute configuration guides to verify socket compatibility.

Integration & Compatibility

The 4XG7A72952 is a factory-configured processor option for the Lenovo ThinkSystem ST650 V2. The ST650 V2 supports dual-socket configurations, meaning a second 4XG7A72952 unit can be added for symmetric multi-processing — effectively doubling the core count to 56 physical cores and 112 threads in a two-socket build. This scaling path is relevant for large enterprise VMS deployments or HPC-adjacent workloads where single-socket headroom isn't sufficient.

Integration with virtualization stacks (VMware vSphere, Microsoft Hyper-V, KVM) is standard — Intel Xeon Gold processors carry full VT-x and VT-d support for hardware-assisted virtualization and I/O virtualization, enabling IOMMU passthrough of GPU cards or capture devices into VMs. For network video recorder deployments consolidating multiple camera feeds, the 56-thread compute profile supports high channel counts in software-based NVR platforms without requiring dedicated GPU decode offload at moderate stream densities.

This processor component carries UNSPSC code 43201503, classifying it as a computing processor component under standard procurement taxonomies — useful for PO systems that require commodity code alignment.

A: The processor has a 205W TDP. Verify that your ST650 V2 power supply and cooling configuration supports this thermal envelope before installation.

Q: Is the LGA 4189 socket backward-compatible with previous-generation Xeon processors?

A: No. LGA 4189 is exclusive to 3rd Gen Intel Xeon Scalable (Ice Lake-SP) processors and is not compatible with LGA 3647 (2nd Gen Cascade Lake) chips. Confirm your ST650 V2 board revision before ordering.

Q: What is the boost frequency of the Xeon Gold 6330?

A: The processor boosts to 3.1 GHz on high-priority cores (base 2.1 GHz on 12 high-priority cores; 1.8 GHz on 16 efficiency cores; 2.0 GHz overall base). The system bus rate is 11.2 GT/s.

Q: What workloads is the Gold 6330's heterogeneous core configuration best suited for?

A: The 12 high-priority cores at 2.1 GHz handle latency-sensitive tasks (live video decode, API serving, interactive queries), while the 16 lower-priority cores at 1.8 GHz absorb background workloads (log processing, storage management). This makes it well-suited for mixed enterprise environments where foreground and background workloads compete for CPU time.

Karl Wilson

When I spec the 4XG7A72952 into a project, the detail I anchor on first is the heterogeneous core split: 12 high-priority cores at 2.1 GHz and 16 efficiency cores at 1.8 GHz within the same 28-core die. That architectural choice has real scheduling consequences in mixed VMS-plus-analytics workloads that a flat 28-core count doesn't tell you.

Technical Highlights:

• 28 Cores / 56 Threads at 205W: At 7.3W per core under full load, the Gold 6330 is reasonably efficient for its core count tier — relevant when you're building out a dense rack where per-U power draw compounds fast across multiple servers.
• 3.1 GHz Boost on Priority Cores: The 1.1 GHz spread between base (2.0 GHz) and boost (3.1 GHz) gives the scheduler meaningful headroom to accelerate foreground threads — important for real-time alerting pipelines where latency on individual events matters, not just aggregate throughput.
• 11.2 GT/s UPI Interconnect: In a dual-socket ST650 V2 build, the UPI rate governs cache-coherent data movement between sockets. At 11.2 GT/s, NUMA-aware workloads (VMware NUMA-optimized scheduling, for example) will perform predictably — but NUMA-unaware applications will still pay a latency penalty on cross-socket memory access.

Deployment Considerations:

• The 205W TDP requires confirming the ST650 V2 fan zone and PSU configuration against Lenovo's thermal matrix — not every base-config ST650 V2 ships with the cooling hardware to support the high-TDP processor row without an upgrade.
• LGA 4189 locks you to Ice Lake-SP exclusively — there is no upgrade path to Sapphire Rapids (LGA 4677) without a board replacement, so plan the platform lifecycle before committing to this socket generation at scale.

The 4XG7A72952 is best positioned in enterprise security operations centers deploying the ST650 V2 as a consolidated VMS host — running 40–80 camera channels in software decode alongside VM-resident analytics, where the 56-thread compute profile defers GPU offload hardware costs until stream density actually demands it.
