Lenovo 4XG7A63435 Intel Xeon Gold 6330N 28-Core Processor Option for ThinkSystem SR630 V2

Overview

The Lenovo 4XG7A63435 is a factory-qualified processor option kit that installs the Intel Xeon Gold 6330N into the ThinkSystem SR630 V2 1U rack server. The 6330N is a 3rd Generation Intel Xeon Scalable processor built on 10 nm SuperFin — a platform targeting network-optimized and telco-adjacent workloads where balanced core density matters more than raw single-thread peak. At 165W TDP in a dual-socket 1U chassis, thermal planning is a real factor: the SR630 V2's cooling is validated for this envelope, but make sure your rack airflow and power circuits support two of these before ordering a dual-socket build.

With 28 cores and 56 threads at a 2.2 GHz base and 3.4 GHz boost, the 4XG7A63435 delivers the core count needed for heavily parallelized server workloads — virtualization hosts, analytics back-ends, video management server compute nodes, or database servers running dozens of concurrent sessions. This is not a workload-per-clock processor; it's a density-per-rack-unit processor.

Key Features

• 28 Cores / 56 Threads at 2.2 GHz Base: At this core count, you can run a meaningful number of virtual machines or container workloads on a single socket. Paired with a second 6330N in a dual-socket SR630 V2, you're looking at 56 physical cores and 112 threads — the kind of density that makes it practical to consolidate several mid-tier application servers onto one physical host.
• 3.4 GHz Turbo Boost: The 1.2 GHz headroom between base and boost (2.2 → 3.4 GHz) is meaningful for bursty workloads — database query spikes, short-duration encode jobs, or analytics tasks that aren't fully parallelized. Sustained all-core loads stay closer to base clock, so benchmark against your actual workload mix before assuming turbo numbers.
• Hybrid Core Architecture — 18 High-Priority + 10 Efficiency Cores: The 6330N implements Intel's tiered-core design: 18 cores run at 2.3 GHz high-priority frequency, while 10 cores operate at 1.9 GHz for background and lower-priority tasks. For workload schedulers that are NUMA and core-priority aware (current Linux kernels, Windows Server 2022), this translates to better latency on foreground workloads without sacrificing total thread count.
• 42 MB L3 Cache: At 42 MB of last-level cache across 28 cores, data-intensive workloads — in-memory databases, large working-set analytics, high-throughput network processing — spend fewer cycles reaching main memory. This is where the N-series designation pays off for network-function and latency-sensitive application hosting.
• 10 nm SuperFin Lithography: The 10 nm node delivers better performance-per-watt than previous-gen 14 nm Xeon Scalable processors. In practice, you get more throughput at 165W than a comparable 14 nm part at the same TDP — which matters when you're constrained by rack power density rather than compute budget.
• 11.2 GT/s System Bus: The UPI (Ultra Path Interconnect) bus rate of 11.2 GT/s governs how fast the two sockets communicate in a dual-socket configuration. Higher UPI bandwidth reduces the NUMA penalty for cross-socket memory access — relevant if your workloads don't fit cleanly into per-socket NUMA domains.
• LGA 4189 Socket, SR630 V2 Platform: The 4XG7A63435 is validated specifically for the ThinkSystem SR630 V2 on the LGA 4189 platform. It installs into a chassis that Lenovo has thermal- and firmware-validated for this TDP. Using Lenovo's qualified option kits rather than retail boxed processors ensures the system's warranty coverage applies to the full configuration — a real consideration for enterprise support contracts.
• 64-Bit Operating Modes: Full 64-bit operation across all cores — no architectural constraints on memory addressability or OS compatibility with current enterprise operating systems and hypervisors.

Integration & Compatibility

The 4XG7A63435 is a processor option kit designed exclusively for the Lenovo ThinkSystem SR630 V2. It is not a standalone retail processor — it ships as a Lenovo-qualified component intended to populate or upgrade the processor socket(s) in an SR630 V2 system. Verify your SR630 V2's current processor and cooling configuration before ordering: some 165W TDP processors require specific heatsink variants, and the SR630 V2 may need a higher-performance heatsink depending on chassis airflow configuration.

The LGA 4189 platform supports up to 6TB of DDR4 memory per socket using 3DS RDIMM at 3200 MT/s — memory population and channel configuration will affect achieved memory bandwidth significantly. If your workloads are memory-bandwidth-bound, consult Lenovo's memory configuration guide for the SR630 V2 before finalizing DIMM counts and speeds.

For software compatibility, the Xeon Gold 6330N supports all current enterprise hypervisors (VMware vSphere, Microsoft Hyper-V, Red Hat KVM) and is compatible with Intel vPro platform features for remote management, relevant in data center environments where physical access is limited.

Frequently Asked Questions

Q: Is the Lenovo 4XG7A63435 compatible with servers other than the ThinkSystem SR630 V2?

A: No. The 4XG7A63435 is a Lenovo-qualified option kit validated specifically for the ThinkSystem SR630 V2. While the underlying processor uses the LGA 4189 socket shared across Ice Lake Xeon platforms, Lenovo option kits include platform-specific firmware validation and thermal qualification. Installing this kit in a non-SR630 V2 system is not a supported configuration.

Q: What is the thermal design power (TDP) of the 6330N processor in this kit, and what does that mean for rack planning?

A: The Intel Xeon Gold 6330N in the 4XG7A63435 has a 165W TDP. In a dual-socket SR630 V2, plan for up to 330W of processor-only power draw before adding memory, storage, and PCIe card loads. Verify your rack PDU and circuit capacity before deploying dual-socket configurations at full TDP.

Q: What is the difference between the 18 high-priority cores and 10 low-priority cores on the 6330N?

A: Intel's tiered core design runs 18 cores at 2.3 GHz (high-priority) and 10 cores at 1.9 GHz (efficiency). Modern OS schedulers place latency-sensitive foreground threads on high-priority cores automatically. This improves response time on mixed workloads without reducing total thread count — but it requires an OS that understands Intel's core hierarchy (Linux 5.15+ or Windows Server 2022 and later).

Q: Does the 4XG7A63435 require a specific heatsink in the SR630 V2?

A: At 165W TDP, the 6330N is a high-thermal-envelope processor. The SR630 V2 platform has heatsink options rated for different TDP ranges. Confirm with Lenovo's configuration guide that your SR630 V2 chassis is equipped with a heatsink validated for 165W before installing this processor option — a standard heatsink designed for lower-TDP processors will not provide adequate cooling.

Q: How many threads does the Xeon Gold 6330N provide, and what workloads benefit most?

A: The 6330N provides 56 threads (28 cores with Hyper-Threading). Workloads that benefit most are those with high concurrency: virtualization hosts running many VMs, containerized microservices environments, multi-threaded analytics, and network function virtualization. Single-threaded workloads that need maximum per-core clock speed should look at higher-frequency Xeon Gold variants instead.

The 4XG7A63435 lands in an interesting spot in the SR630 V2 lineup — 28 cores at 165W is a high-density, high-thermal configuration that suits consolidation-heavy deployments, but it demands that your infrastructure team has thought through both the rack power envelope and the OS scheduler behavior with Intel's hybrid core architecture before provisioning starts.

Technical Highlights:

• 28C/56T at 2.2–3.4 GHz: The 1.2 GHz base-to-boost spread gives the scheduler real room to work with on bursty workloads while maintaining a dense 28-core footprint — useful on VMS back-ends processing motion analytics or transcoding streams across many concurrent camera feeds.
• 42 MB L3 Cache: For database-backed applications or in-memory analytics engines, 42 MB of last-level cache keeps more working data on-die and reduces memory latency — measurable throughput improvement on workloads with moderate-to-large hot datasets.
• 11.2 GT/s UPI Bus: In a dual-socket SR630 V2 build, the 11.2 GT/s UPI rate keeps cross-socket cache coherency traffic from becoming a bottleneck — relevant if you're running a single large VM or database instance that spans both NUMA nodes.

Deployment Considerations:

• The 165W TDP is non-trivial in a 1U chassis — confirm SR630 V2 heatsink SKU compatibility before ordering, especially if this is a processor upgrade into an existing chassis that may have shipped with a lower-TDP heatsink.
• The hybrid core model (18 high-priority at 2.3 GHz, 10 efficiency at 1.9 GHz) can produce unexpected scheduling behavior on older hypervisors or Linux kernels below 5.15 that don't expose Intel's core hierarchy — test scheduler affinity settings in non-trivial workload configurations before full deployment.

This processor option is a strong fit for a ThinkSystem SR630 V2 being deployed as a dense virtualization host or a compute node in a video analytics or VMS cluster, where thread count and cache depth matter more than maximum single-core frequency.
