The Intel Xeon E3-1265L v2 was a server/workstation processor with 4 cores, launched in Q2 2012. It is part of the Xeon lineup, using the Ivy Bridge architecture with Socket LGA1155. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 8 threads. Xeon E3-1265L v2 has 8 MB of L3 cache and operates at 2.5 GHz by default, with a maximum turbo frequency of 3.5 GHz depending on workload conditions. Intel is manufacturing the Xeon E3-1265L v2 on a 22 nm production process, featuring advanced power efficiency. With a low TDP of just 45 W, this processor is designed for energy-conscious environments while still delivering solid performance.

Intel's processor supports DDR3 memory with a dual-channel interface, running at speeds up to 1600 MHz. ECC memory is supported, which is essential for mission-critical applications to ensure data integrity. For communication with other system components, the Xeon E3-1265L v2 uses a PCI-Express Gen 3 connection, providing improved bandwidth over previous generations. Unlike some Xeon models, this processor includes Intel HD Graphics (P3000), eliminating the need for a dedicated graphics card in basic usage scenarios.

Hardware virtualization is fully supported on the Xeon E3-1265L v2, enhancing virtual machine performance. The multiplier is locked, restricting overclocking capabilities, but the efficient 22 nm process and low power consumption make this CPU an excellent choice for compact servers and workstations where thermal and power constraints are a concern.
