The Intel Xeon E3-1125C is a server/workstation processor with 4 cores, launched in May 2012. It is part of the Xeon E3 lineup, using the Gladden architecture with BGA 1283. Xeon E3-1125C has 8 MB of L3 cache and operates at 2000 MHz. Intel is building the Xeon E3-1125C on a 32 nm production process using 1,160 million transistors. The multiplier is locked on Xeon E3-1125C, which limits its overclocking capabilities.
With a TDP of 40 W, the Xeon E3-1125C consumes typical power levels for a modern PC. Intel's processor supports DDR3 memory. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. Although neither the processor nor its chipsets support integrated graphics, certain motherboards include dedicated graphics chipset that can provide some basic display output functionality.
Hardware virtualization is available on the Xeon E3-1125C, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
