Intel CD8069504343701 Xeon Silver 4214R 12-Core Processor

Name: Intel CD8069504343701 Xeon Silver 4214R 12-Core Processor
Brand: Intel
SKU: CD8069504343701

Overview

The Intel Xeon Silver 4214R is a second-generation Cascade Lake processor built on 14nm lithography, delivering 12 physical cores and 24 threads at a 2.4 GHz base clock within a 100W thermal design power. In context, this positions it as a mid-range data center CPU — it provides enough parallel compute for moderate VM consolidation, small-to-medium database instances, and general-purpose infrastructure services without the power draw or cost of Gold and Platinum tier Xeons. The 16.5 MB shared L3 cache, six-channel DDR4 support at 2400 MHz, and 48 PCIe 3.0 lanes define its bandwidth envelope: adequate for standard rack workloads, but not designed for memory-bandwidth-intensive HPC or heavily I/O-bound storage arrays.

The 4214R fits best in single or dual-socket servers running virtualization platforms (VMware ESXi, Hyper-V, Proxmox), mid-tier SQL Server or PostgreSQL instances, and network infrastructure roles like reverse proxies or DNS servers. Its Socket 3647 compatibility makes it a drop-in refresh upgrade for organizations already running first-gen Xeon Scalable platforms — the same motherboard, same cooler, better clocks. Cascade Lake's built-in hardware mitigations for side-channel vulnerabilities also mean less performance overhead from security patches compared to earlier Skylake-SP silicon. For budget-conscious data center builds that need dependable multi-threaded throughput without overprovisioning, the Silver 4214R represents a pragmatic choice — just be aware that the Silver tier's memory speed cap and single UPI link become tangible constraints if workloads scale beyond moderate density.

Pros & Cons

👍 Pros

Twelve cores with Hyper-Threading deliver 24 threads at a 100W TDP, providing strong multi-threaded density per watt for virtualization, storage, and networking workloads.
Cascade Lake architecture includes hardware mitigations for Spectre and Meltdown variants, reducing the performance penalty of software-only security patches.
Socket 3647 compatibility allows drop-in upgrades from first-gen Xeon Scalable processors on existing C621/C622 motherboards without a platform change.
16.5 MB of L3 cache provides sufficient working set capacity for database queries and middleware applications at this core count.
100W TDP keeps cooling requirements manageable in dense rack environments where per-node thermal budget is a constraint.

👎 Cons

2400 MHz maximum memory speed is a generation behind — Gold and Platinum Xeon tiers support 2933 MHz DDR4, which limits memory-bandwidth-sensitive workloads on this Silver-tier chip.
16.5 MB of shared L3 cache across 12 cores means only 1.375 MB per core — compute-intensive workloads with large working sets may see more cache misses than higher-tier Xeons.
No support for Intel Optane Persistent Memory (DCPMM) in App Direct mode, which is restricted to Gold and Platinum SKUs — limiting next-gen storage tier architectures.
Single UPI link (versus two or three on Gold/Platinum) constrains inter-socket bandwidth in dual-socket configurations running NUMA-sensitive workloads.
PCIe lanes are limited to 48 compared to higher-tier Xeons, which can bottleneck heavily I/O-dependent configurations with multiple NVMe drives and network adapters.

Frequently Asked Questions

What socket does the Xeon Silver 4214R require?

The 4214R uses Socket 3647 (LGA 3647), which is the standard interface for Intel's Cascade Lake and Skylake-SP Xeon Scalable processors. It's compatible with C621 and C622 chipset server motherboards designed for the second-generation Xeon Scalable platform.

How does the 4214R compare to the non-R Xeon Silver 4214?

The 4214R is Intel's "refresh" of the 4214 — same 12 cores and socket, but with a higher base clock (2.4 GHz vs. 2.2 GHz) and higher turbo frequency, providing measurably better single-threaded and multi-threaded throughput at the same 100W TDP. It's a drop-in performance upgrade on compatible boards.

What memory configurations does this processor support?

The 4214R supports six-channel DDR4 memory at up to 2400 MHz. For optimal bandwidth, populate one DIMM per channel (six DIMMs) or two DIMMs per channel (twelve DIMMs) depending on your workload's capacity and bandwidth requirements.

Is this processor suitable for virtualization workloads?

Yes. Twelve cores with Hyper-Threading provide 24 threads, which is sufficient for moderate VM density. It supports Intel VT-x, VT-d, and EPT — the full virtualization feature set. For heavier VM consolidation ratios, consider dual-socket configurations or stepping up to Gold-tier Xeon processors with higher core counts.

Can I run two of these in a dual-socket server?

Yes. The Xeon Silver 4214R supports multi-socket configurations via Intel UPI (Ultra Path Interconnect). In a dual-socket board, you'll get 24 cores and 48 threads total, with UPI links handling inter-socket communication. Ensure your motherboard supports dual Xeon Scalable processors.
