The Intel Xeon E3-1281 v3 was a server/workstation processor with 4 cores, launched in May 2014. It is part of the Xeon E3 lineup, using the Haswell architecture with Socket LGA1150. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 8 threads. Xeon E3-1281 v3 has 8 MB of L3 cache and operates at a base frequency of 3.7 GHz, with a maximum turbo frequency of 4.1 GHz depending on workload conditions. Intel manufactured the Xeon E3-1281 v3 on a 22 nm production process, featuring advanced power efficiency. With a TDP of 82 W, this processor offers balanced performance and power consumption, making it suitable for various professional workloads. Intel's processor supports DDR3 memory with a dual-channel interface at speeds up to 1600 MHz. ECC memory is supported as well, which is crucial for mission-critical applications to prevent data corruption. For system communication, the Xeon E3-1281 v3 utilizes a PCI-Express Gen 3 connection, providing enhanced bandwidth for peripheral devices. This processor does not include integrated graphics, so a discrete graphics card is required for display output. Hardware virtualization technology (VT-x) is supported on the Xeon E3-1281 v3, significantly improving virtual machine performance and management capabilities. The processor also features Intel's Advanced Vector Extensions (AVX) for accelerated floating-point operations, making it well-suited for technical computing applications.
