The Intel Xeon E3-1220 v6 was a server/workstation processor with 4 cores, launched in January 2017. It is part of the Xeon lineup, using the Kaby Lake architecture with Socket LGA1151. The processor operates at a base frequency of 3.0 GHz but does not support Turbo Boost technology. Intel manufactured the Xeon E3-1220 v6 on a 14 nm++ production process, offering improved power efficiency and performance over previous generations. With a TDP of 72 W, this processor is relatively power-efficient compared to other Xeon models, making it suitable for systems where energy consumption is a concern.

Xeon E3-1220 v6 features 8 MB of L3 cache, enhancing performance for data-intensive workloads. The processor supports DDR4 memory with a dual-channel interface, with a maximum supported speed of DDR4-2400. ECC memory is also supported, which is crucial for mission-critical applications to prevent data corruption. For communication with other system components, the Xeon E3-1220 v6 uses a PCI-Express 3.0 connection.

This processor does not include integrated graphics, so a discrete graphics card is required for display output. Hardware virtualization is supported on the Xeon E3-1220 v6, improving performance for virtualized environments. The processor does not support Intel Hyper-Threading, limiting it to 4 threads. The multiplier is locked, restricting overclocking potential. Overall, the Xeon E3-1220 v6 is a balanced choice for entry-level server and workstation applications, offering solid performance with moderate power consumption.
