Intel has launched their fastest chip for the microserver market under the Xeon D family. The chip known as the Xeon D-1571 comes with the highest core count available on the micorserver platform and based on Intel's Broadwell architecture which uses the 14nm FinFET technology. The Xeon D family consists of several SOCs which are aimed at the microserver and storage markets, delivering the Xeon level architecture in a low TDP package.
Intel's 16 Core, Broadwell Powered, Xeon D -1571 Processor Launched
CPUWorld was first to report the launch of the new Xeon D-1571 processor and from the looks of it, the latest entrant to the lineup is also the highest core count processor aimed at microservers. The Xeon D-1571 has 16 Broadwell cores which are the same high-end variants that will be used on the Xeon E5 V4 "Broadwell-EP" line up which is coming soon in Q1 2016. The specifications include a 14nm process which allows the chip to clock in at a speed of 1.3 GHz, 24 MB of LLC (L3 Cache) and a TDP of just 45W. The chip has the same TDP of its 8 core sibling, the Xeon D-1541 but trades off 35% of its clock speed to incorporate 8 additional Broadwell cores. Since this is an Intel part, the chip also features hyper threading
Alongside the Xeon D-1571, Intel also plans to launch a faster variant called the Xeon D-1587 (spotted by Computerbase) which will come with higher clock speeds but retain the rest of the features. The Xeon D-1587 will have a TDP of 65W which is due to the higher clock speeds. The Xeon D-1571 will retail at a price of $1222 US while the Xeon D-1587 will be priced even higher. All of the chips are available in BGA package so you will have to purchase the platform directly from an Intel AIB partner such as SuperMicro or Gigabyte where they are expected to hit retail soon.
Since the Xeon D processors feature the same architecture level and hierarchy of the enterprise level Xeon chips, we are looking at the same Broadwell architecture which supports features such as VT-X/VT-d virtualization, RAS features and the entire TXT, AVX2, TSX Instruction set and since this is also a SOC (System on Chip) design the chipset logic will be incorporated on system and will make for a more efficient foot print than the customary two chip solution where the chipset logic lies on the motherboard.
Additional features will include support for either dual-channel DDR4 memory (2133 MHz) or DDR3L ram (1600 MHz). The system can incorporate up to 2 DIMMs per channel with the total capacity support up to 128 GB (RDIMM) or 64 GB (UDIMM/SODIMM) in ECC or non-ECC types. For expansion, the SOCs feature a total of 24 PCI-e Gen 3.0 lanes and 8 PCI-e Gen 2.0 lanes. Integrated I/O is offered in the form of dual 10 Gigabit Ethernet LAN ports, 4 USB 3.0, 4 USB 2.0 ports and 6 SATA 3 ports. Expect more information about the faster clocked variant in the coming weeks.
