The Intel Xeon E5-1428L is a server/workstation processor with 6 cores, launched in May 2012. It is part of the Xeon E5 lineup, using the Sandy Bridge-EN architecture with Socket 1356. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 12 threads. Xeon E5-1428L has 15 MB of L3 cache and operates at 1800 MHz. Intel is building the Xeon E5-1428L on a 32 nm production process using 1,270 million transistors. The multiplier is locked on Xeon E5-1428L, which limits its overclocking capabilities.
With a TDP of 60 W, the Xeon E5-1428L 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. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon E5-1428L, 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.
