In May, we published preliminary lineup of upcoming Xeon D systems on a chip for communications and storage markets. Back then, we gave some details on Xeon D-1518, D-1528, D-1537, D-1548 models, and Pentium D 1503, D 1507 and D 1517. The SoCs were reported to have 2, 4, 6 or 8 "Broadwell" CPU cores, up to 12 MB of cache and up to 45 Watt TDP. According to our sources, Intel have made some changes to the lineup, which is now comprised of 13 Xeon D and Pentium D SKUs. Even more interesting is that Intel managed to double the maximum number of cores, and consequentially combined cache size, of Xeon D design, and the nearing Xeon D launch may include a few 12-core and 16-core models with 18 MB and 24 MB cache.
Planned Pentium D models are D-1507, D-1508, D-1517 and D-1519. Xeon D lineup was also expanded, and it consists of D-1518, D-1527, D-1528, D-1537, D-1539, D-1548, D-1557, D-1567 and D-1577 models. The Pentium D-1519 and Xeon D-1539 chips will be qualified for extended temperature range operations. We also know that the D-1577 will have 16 cores, but we do not have complete SoC specifications yet. With the exception of larger number of cores on some SKUs, the processors are expected to have the same features as Xeon D-15x0 line for microservers. They will incorporate most of Broadwell technologies and support up to 128 GB of DDR3L or DDR4 memory. They will also integrate PCI-e 2.0 and 3.0, SATA 3.0, USB 2.0/3.0 and Ethernet interface controllers. Reportedly, Xeon D and Pentium D processors will be launched sometime this quarter.
