The Intel Xeon E3-1276 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 E3-1276 v3 has 8 MB of L3 cache and operates at 3.6 GHz by default, with a maximum turbo frequency of 4.0 GHz depending on workload conditions. Intel manufactured the Xeon E3-1276 v3 on a 22 nm production process, featuring advanced power efficiency. With a TDP of 84 W, this processor balances performance and power consumption, though adequate cooling is still recommended. The processor supports DDR3 memory with a dual-channel interface at speeds up to 1600 MHz. ECC memory is supported, providing enhanced data integrity for mission-critical applications. For system connectivity, the Xeon E3-1276 v3 utilizes a PCI-Express Gen 3 interface. This processor does not include integrated graphics, so a discrete graphics card is required for display output. Hardware virtualization technology (VT-x) is supported, enabling improved virtual machine performance. The chip also features Intel's Advanced Vector Extensions (AVX) for enhanced floating-point performance in demanding workloads.
