Lenovo 4XG7A63575 Intel Xeon Gold 6348 28-Core Processor Option Kit

Overview

The Lenovo 4XG7A63575 is a factory-configured processor option kit pairing the Intel Xeon Gold 6348 with the ThinkSystem SR650 V2 platform. Rated at 235W TDP with 28 cores, 56 threads, and a base clock of 2.6 GHz, this is a high-core-count compute upgrade aimed at workloads that need sustained multi-threaded throughput — think large-scale video analytics backends, enterprise virtualization hosts, or high-density containerized environments where per-socket core count matters more than single-thread speed. If you're building or expanding an SR650 V2 deployment and need to step up from a lower-bin Xeon, this kit is how you do it through Lenovo's supply chain.

Key Features

• 28 Cores / 56 Threads at 2.6 GHz Base: The Xeon Gold 6348's 28-core layout gives you 56 logical threads per socket under hyper-threading. In a dual-socket SR650 V2 configuration that's 112 logical cores — enough headroom to run dozens of concurrent VM workloads or analytics inference pipelines without core contention.
• 3.5 GHz Turbo Boost: The processor steps up from its 2.6 GHz base to 3.5 GHz under Turbo Boost for lightly threaded tasks. For workloads that mix burst single-thread operations (database queries, control-plane processes) with sustained multi-threaded compute, this spread gives you flexibility without requiring separate SKUs for different workload types.
• Heterogeneous Core Architecture — 12 High-Priority + 16 Efficiency Cores: Intel segments the 28 cores into 12 high-priority cores running at 2.8 GHz and 16 lower-priority cores at 2.5 GHz. This allows the OS and hypervisor to steer latency-sensitive threads to the faster cores while background and batch workloads consume the efficiency tier — relevant if you're running mixed workloads on a single server rather than purpose-built nodes.
• 235W TDP — Plan Your Cooling and Power Budget Accordingly: At 235W, the 6348 sits in the high-TDP bracket for the Ice Lake-SP generation. The SR650 V2's cooling subsystem is rated for this, but in a dual-socket configuration you're looking at up to 470W of processor-only thermal load before memory, drives, and PCIe cards. Size your PDU and UPS accordingly before deploying.
• LGA 4189 Socket — Ice Lake-SP Platform: The LGA 4189 socket is the standard mount for 3rd Generation Intel Xeon Scalable processors. This means compatibility is locked to SR650 V2 and other Ice Lake-SP platforms — you cannot drop this into a Cascade Lake (LGA 3647) system. Verify your server generation before ordering.
• 10 nm Lithography: Built on Intel's 10 nm SuperFin process, the 6348 delivers improved power efficiency per core compared to the 14 nm Cascade Lake predecessor. In always-on server deployments, that efficiency delta accumulates over months of runtime — meaningful when calculating total cost of ownership at scale.
• 11.2 GT/s UPI System Bus: The 11.2 GT/s Ultra Path Interconnect rate governs inter-socket bandwidth in a dual-processor configuration. For workloads that share data across sockets (in-memory databases, distributed caches), this bus speed is the ceiling on cross-socket throughput — the 6348's 11.2 GT/s UPI is the standard rate for this processor tier.
• 64-Bit Operating Mode: Supports all major 64-bit enterprise operating systems and hypervisors. No legacy 32-bit constraints — deploy VMware vSphere, Red Hat Enterprise Linux, Windows Server, or container-native OS stacks without compatibility caveats.

Integration and Compatibility

The 4XG7A63575 is a Lenovo option kit validated for the ThinkSystem SR650 V2. Lenovo option kits are validated against specific server generations — this processor is matched to the Ice Lake-SP platform and will not install in prior-generation SR650 (V1) units using LGA 3647. Confirm your server's product number includes "V2" before procurement. The SR650 V2 supports dual-socket configurations, so a second 4XG7A63575 can populate the second processor socket for full symmetric multiprocessing. For enterprise workloads running video management software at scale, a network video recorder or dedicated analytics server upstream of this platform can offload inference tasks, keeping the SR650 V2 free for core data management and storage functions. Pair with appropriate server storage options validated for the SR650 V2 to complete the platform build. For broader context on building surveillance infrastructure around compute platforms like this, the surveillance server category covers purpose-built and enterprise-adapted options.

Frequently Asked Questions

Q: Is the 4XG7A63575 compatible with the ThinkSystem SR650 V1?

A: No. The Intel Xeon Gold 6348 uses the LGA 4189 socket, which is specific to 3rd Generation Intel Xeon Scalable (Ice Lake-SP) platforms. The SR650 V1 uses an LGA 3647 socket (Cascade Lake / Cooper Lake). This option kit is validated for the SR650 V2 only.

Q: What is the TDP of the Xeon Gold 6348 in this kit?

A: The Intel Xeon Gold 6348 carries a 235W TDP. In a dual-socket SR650 V2 configuration, plan for up to 470W of processor thermal load before accounting for memory, storage, and PCIe add-in cards.

Q: Can the SR650 V2 run two of these processors simultaneously?

A: Yes. The SR650 V2 supports dual-socket symmetric multiprocessing. Installing a second 4XG7A63575 brings the total to 56 physical cores and 112 logical threads per server — suitable for high-density virtualization or large-scale analytics workloads.

Q: What is the maximum Turbo Boost frequency of the Xeon Gold 6348?

A: The processor boosts to 3.5 GHz under Turbo Boost for lightly threaded workloads, up from the 2.6 GHz base clock.

Q: What operating systems are supported?

A: The Xeon Gold 6348 runs in 64-bit mode and is compatible with all major 64-bit enterprise operating systems and hypervisors, including VMware vSphere, Microsoft Windows Server, and Red Hat Enterprise Linux, subject to Lenovo's SR650 V2 compatibility matrix.

Q: How does the high-priority / low-priority core split affect workload scheduling?

A: The 6348 splits its 28 cores into 12 high-priority cores at 2.8 GHz and 16 lower-priority cores at 2.5 GHz. Modern hypervisors and OS schedulers can direct latency-sensitive threads to the faster cores, which is useful in mixed-workload environments running both interactive and batch jobs on the same server.

The 4XG7A63575 is one of the higher-TDP options in the SR650 V2 processor lineup — the Intel Xeon Gold 6348's 235W envelope puts it near the top of what the platform's cooling subsystem is designed to handle, and that's worth factoring in before you order. What you get for that thermal budget is 28 physical cores at 2.6 GHz base with a 3.5 GHz Turbo ceiling, which is a meaningful compute density for any workload running sustained parallel threads.

Technical Highlights:

• 28 Cores / 56 Threads: At full SMT, each socket delivers 56 logical threads — dual-socket configurations reach 112 logical threads per server, which is the figure that matters when sizing VM density or analytics pipeline concurrency.
• Heterogeneous Core Tiers: The 12 high-priority cores at 2.8 GHz versus 16 lower-priority cores at 2.5 GHz is a real scheduling lever. If you're running a hypervisor that supports core-type-aware scheduling, you can pin latency-sensitive workloads to the faster tier without touching clock management manually.
• 11.2 GT/s UPI Bus: In a dual-socket deployment, inter-socket bandwidth is governed by this 11.2 GT/s UPI link. For workloads that require frequent cross-NUMA data access — think distributed in-memory databases or NUMA-unaware analytics frameworks — this is the number to keep in mind when profiling performance.

Deployment Considerations:

• The LGA 4189 socket locks this processor to Ice Lake-SP platforms only. Double-check your server's generation — "SR650" without "V2" in the product number means LGA 3647, and this kit physically will not fit.
• At 235W per socket, a dual-processor SR650 V2 draws substantial power from processor TDP alone. Verify rack PDU capacity and UPS runtime calculations include this load before commissioning the build.

This option kit is best suited for SR650 V2 deployments being scaled for high-density virtualization, large-scale video analytics backends, or compute-heavy enterprise workloads where per-socket core count is the primary sizing constraint — not single-threaded peak speed.
