Xeon E5-1620

The Xeon E5-1620 is a 4-core / 8-thread processor based on the Sandy Bridge-E (2011−2013) architecture, manufactured on a 32 nm process node. It reaches a maximum boost clock of 3.8 GHz from a base frequency of 3.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 10240 kB (total) L3 cache (3D V-Cache technology), this processor has a significant gaming advantage — the large cache drastically reduces memory latency in game engines., plus 256 kB (per core) of L2 cache and 64 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 5,848, placing it in the Entry Level performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 612, while multi-core reaches 2,250. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 3,469.

The Xeon E5-1620 fits into the LGA2011 socket and supports PCIe 2.0 with 40 total PCIe lanes for expansion cards and storage. It supports DDR3 memory at speeds up to DDR3-1600 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 375 GB across 4 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers.

Virtualization: true — enables running virtual machines efficiently (important for development and server workloads).

The Xeon E5-1620 has a rated TDP (Thermal Design Power) of 130 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. Recommended cooling: High-End Air.

At an average price of $70 (MSRP: $885), the Xeon E5-1620 delivers 84 PassMark points per dollar. Performance ranking position: #1741 out of all indexed processors.
