Lenovo 4XG7A63282 SR630 Xeon Gold 6246R

Lenovo 4XG7A63282 Intel Xeon Gold 6246R Server Processor

Overview

The Lenovo 4XG7A63282 is a 2nd Generation Intel Xeon Gold 6246R processor engineered for Lenovo ThinkSystem SR630 server platforms. Built on the Cascade Lake microarchitecture at 14nm, this 16-core, 32-thread CPU runs a 3.4 GHz base clock and boosts to 4.1 GHz — making it a strong fit for compute-intensive server workloads where single-threaded peak frequency matters alongside parallel throughput. If you are specifying a processor upgrade or replacement for an SR630 node, the 4XG7A63282 slots directly into the LGA 3647 (Socket P) without platform changes.

Key Features

• 16 Cores / 32 Threads at 3.4 GHz Base: The Xeon Gold 6246R delivers a 3.4 GHz sustained base clock across all 16 cores — substantially higher than many 16-core Cascade Lake parts. In practice, that means less frequency droop under sustained all-core loads like video transcoding, database queries, or VMS analytics engines running simultaneously across dozens of camera streams.
• 4.1 GHz Turbo Boost: Single-threaded workloads — report generation, VMS playback decoding, or serial configuration tasks — can hit 4.1 GHz. That 700 MHz headroom above base clock is meaningful in mixed workloads where some threads saturate and others idle.
• 35.75 MB L3 Cache: The on-die 35.75 MB cache reduces main-memory round-trips for working datasets that fit within it. For VMS servers handling concurrent stream decoding and motion-detection inference, a larger cache directly lowers latency between frame processing cycles.
• 32 Threads via Hyper-Threading: Two logical threads per physical core allows the OS scheduler to pipeline independent instruction streams. In virtualized SR630 environments — where multiple VMs share a single socket — this translates to better CPU utilization without provisioning a second socket.
• 205W TDP: At 205W thermal design power, this processor sits at the high end of the Cascade Lake Gold tier. Verify your SR630 chassis cooling configuration supports this TDP before deployment — the SR630's fan zones are configurable, but undersized cooling will trigger thermal throttling under sustained load.
• LGA 3647 (Socket P) with Dual UPI Links: Two UltraPath Interconnect (UPI) links support multi-socket coherency. In a dual-socket SR630 configuration, the two UPI links provide the inter-processor fabric for cache coherence and memory sharing — relevant if you are scaling to a two-socket build for higher aggregate memory bandwidth.
• 64-bit Operating Mode: Full 64-bit instruction support is required for modern server operating systems and hypervisors. All production enterprise workloads — VMware ESXi, Windows Server, RHEL — run natively in 64-bit mode on this processor.
• 2nd Gen Intel Xeon Scalable (Cascade Lake): Cascade Lake adds hardware mitigations for Spectre and Meltdown variants built into silicon — avoiding the software-patched performance penalties that affected earlier Skylake-SP Xeon platforms in high-I/O workloads.

Integration and Compatibility

The 4XG7A63282 is a Lenovo-qualified component for the Lenovo ThinkSystem server platform, specifically the SR630. Processor compatibility in enterprise servers is platform-specific — verify against Lenovo's SR630 supported processor matrix before ordering if you are populating a second socket or upgrading an existing node. This processor targets rack-mount server deployments using Intel's Xeon Scalable ecosystem; it is not interchangeable with consumer or workstation socket types. For guidance on pairing processors with the right storage and memory configuration, review the server configuration guide. If your workload is security surveillance, pairing this CPU with sufficient NVR-class storage and a capable network switching layer ensures the compute and I/O sides stay balanced.

Frequently Asked Questions

Q: What server platform is the Lenovo 4XG7A63282 compatible with?

A: The 4XG7A63282 is a Lenovo-qualified processor for the ThinkSystem SR630 server. It uses the LGA 3647 (Socket P) socket. Always verify against Lenovo's official SR630 compatibility matrix before ordering, as processor support is platform-specific and BIOS-version dependent.

Q: What is the base and boost clock speed of the Xeon Gold 6246R in the 4XG7A63282?

A: The Intel Xeon Gold 6246R in this part runs at 3.4 GHz base frequency and boosts to 4.1 GHz under turbo conditions, with 16 cores and 32 threads.

Q: What is the TDP of the 4XG7A63282 and does it require special cooling?

A: The processor has a 205W Thermal Design Power (TDP). This is at the high end for Cascade Lake Gold-tier processors. Confirm your SR630 chassis cooling configuration is rated to handle this TDP — sustained loads without adequate airflow will trigger thermal throttling.

Q: Is the Xeon Gold 6246R a single-socket or dual-socket processor?

A: The Xeon Gold 6246R supports dual-socket configurations. It features two UltraPath Interconnect (UPI) links for inter-processor coherency, making it suitable for two-socket SR630 builds that require higher aggregate memory bandwidth or core count.

Q: What microarchitecture and fabrication node does the 4XG7A63282 use?

A: This processor is built on Intel's Cascade Lake microarchitecture at 14nm lithography. Cascade Lake includes hardware-level mitigations for Spectre and Meltdown, which helps avoid the performance penalties associated with software-only patches on earlier Skylake-SP Xeon platforms.

Q: How much cache does the Xeon Gold 6246R provide?

A: The processor includes 35.75 MB of L3 cache. This larger on-die cache is beneficial for workloads with frequently reused data sets, reducing main-memory latency in applications like concurrent video stream processing or database query caching.

Ted Perry

The 4XG7A63282 stands out in the Cascade Lake Gold lineup specifically because of its 3.4 GHz base clock — that is unusually high for a 16-core part at this TDP tier, and it matters when you are running a VMS server where per-stream decode tasks are largely single-threaded and need sustained, not just burst, frequency. I have specified this processor in SR630 builds for large-scale surveillance deployments where the customer was running 80-plus concurrent H.265 streams through a software VMS and could not afford the clock-speed penalties of a higher core-count, lower-frequency alternative.

Technical Highlights:

• 3.4 GHz sustained base / 4.1 GHz turbo: The 700 MHz spread between base and boost gives you meaningful burst capacity for decode spikes without sacrificing sustained throughput — key in environments where camera motion events create intermittent decode surges across the channel pool.
• 35.75 MB L3 cache: For VMS software that caches frame buffers and index tables in-process, keeping more of that working set on-die cuts round-trip latency to DRAM noticeably — particularly relevant when recording retention databases grow large enough to compete for cache with live decode pipelines.
• Dual UPI links (LGA 3647 Socket P): Two UPI links support coherent dual-socket SR630 configurations. If a single-socket build saturates at peak channel load, moving to a two-socket SR630 with a matching processor is a straight scale path — no platform change required.

Deployment Considerations:

• At 205W TDP, this CPU requires verified SR630 fan zone configuration before deployment. Check Lenovo's XClarity Controller thermal profiles and confirm your rack has adequate front-to-back airflow — a dense rack with multiple 205W-class nodes needs deliberate CFM planning.
• Cascade Lake processors are BIOS-version dependent on the SR630. Ensure the SR630 firmware is updated to a release that enumerates the 6246R before you seat the processor — a mismatch results in the node posting at reduced capability or failing POST entirely.

This processor is the right call for SR630-based VMS servers in enterprise surveillance installations — specifically where the workload profile skews toward high per-core frequency rather than maximum core count, such as a 64-to-96-camera Milestone or Genetec node running software-based H.265 decode without GPU offload.
