Xeon Gold 5220R

The Xeon Gold 5220R is a 24-core / 48-thread processor based on the Cascade Lake (2019−2020) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4 GHz from a base frequency of 2.2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 35.75 MB of L3 cache, plus 24 MB of L2 cache and 1.5 MB of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 30,372, placing it in the High-End performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,327.

The Xeon Gold 5220R fits into the LGA3647 socket and supports PCIe 3.0 with 48 total PCIe lanes for expansion cards and storage. It supports DDR4-2667 memory at speeds up to DDR4-2667 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 1024 GB across 6 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers.

It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: Yes — enables running virtual machines efficiently (important for development and server workloads).

The Xeon Gold 5220R has a rated TDP (Thermal Design Power) of 150 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately.

At an average price of $1,015 (MSRP: $1780), the Xeon Gold 5220R delivers 30 PassMark points per dollar. Performance ranking position: #423 out of all indexed processors.
