Product Overview
The Intel Xeon E3-1265L v3 Server CPU is engineered to deliver robust performance, making it an ideal choice for data-intensive applications and server environments. With a base frequency of 2.50GHz and the ability to turbo boost to impressive speeds—up to 3.70GHz on a single core, and 3.10GHz across four cores—this microprocessor ensures seamless operation even under heavy workloads. Its advanced Haswell microarchitecture allows for optimized processing, while the LGA1150 socket design complements a wide range of server motherboards.
Featuring four cores and eight threads, the E3-1265L v3 is crafted to enhance multitasking and improve performance for parallel processing tasks. It operates on a 64-bit data width, ensuring compatibility with modern applications and operating systems. The CPU supports a generous level 3 cache of 8MB, which helps reduce latency and speed up data retrieval significantly.
Equipped with integrated Intel HD Graphics, this processor also provides basic graphical capabilities, supporting up to three displays with a maximum frequency of 1200 MHz. Its efficient energy use is highlighted by a Thermal Design Power (TDP) of just 45 watts, making it suitable for energy-conscious server deployments.
Memory performance is supported through dual-channel architecture, accommodating DDR3-1333 and DDR3-1600, with the capability of harnessing up to 32 GB of physical memory and a maximum bandwidth of 25.6 GB/s. Enhanced reliability features, including ECC support, make the E3-1265L v3 an excellent fit for mission-critical applications where data integrity is paramount.
Whether powering a compact server or scaling up a data center, the Intel Xeon E3-1265L v3 is a reliable choice that combines performance, efficiency, and flexibility.
