Lenovo Xeon Gold 5218R - 20-Core Processor - 2.1 GHz - Server Upgrade

Lenovo Xeon Gold 5218R - 20-Core Processor delivers robust server performance based on Intel's Cascade Lake architecture and is ideal for demanding data-center workloads.

This Intel 2nd Generation Xeon Scalable processor (model 5218R) runs at a base frequency of 2.1 GHz and can boost up to 4.0 GHz, offering a balance of steady throughput and on-demand turbo performance for bursty server tasks.

With 20 physical cores and 40 threads, the Xeon Gold 5218R supports 64-bit operation and Intel Hyper-Threading, making it well suited to virtualization, database processing and heavily threaded applications common in enterprise environments.

The processor supports up to 1 TB of DDR4-SDRAM across a hexa-channel memory configuration at up to 2667 MHz and includes ECC support to protect data integrity in mission-critical servers and workstations.

Designed for the LGA 3647 (Socket P) platform, this CPU has 27.5 MB of cache, a 125 W TDP and 48 PCIe 3.0 lanes, enabling fast I/O and large-memory, high-throughput configurations. It also supports Intel technologies such as AVX-512, AES-NI, VT-x/VT-d, Turbo Boost 2.0 and Deep Learning Boost.

Typical use cases include virtualization hosts (2S scalable systems), high-performance databases, analytics and machine learning inference where single-socket or dual-socket scalability, memory capacity and AVX acceleration improve workload performance.

Compatibility and reliability features—such as Intel Virtualization, Trusted Execution Technology, Intel VMD and Optane DC persistent memory support—make this a strong upgrade option for enterprise servers seeking improved compute density and security.
