Intel BGA 1667
The Intel Xeon D-1577 is a server/workstation processor with 16 cores, launched in February 2016, at an MSRP of $1. It is part of the Xeon D lineup, using the Broadwell-DE architecture with BGA 1667. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 32 threads. Xeon D-1577 has 1.5 MB of L3 cache per core and operates at 1300 MHz by default, but can boost up to 2.1 GHz, depending on the workload. Intel is making the Xeon D-1577 on a 14 nm production node using 3,200 million transistors. The multiplier is locked on Xeon D-1577, which limits its overclocking potential.
With a TDP of 45 W, the Xeon D-1577 consumes typical power levels for a modern PC. Intel's processor supports DDR3 and DDR4 memory with a dual-channel interface. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the machine, Xeon D-1577 uses a PCI-Express Gen 3 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon D-1577, 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) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512.
