Broadwell for servers was noteworthy for the Xeon-D line, which has some neat performance characteristics in a tiny power envelope, but it was very targeted at the laptop market - hell, there were only 6 models of desktop processors, compared to 32 laptop models, or 50+ server processors (half of which are the Xeon-D line, and the other half were so delayed that the E3 Skylakes landed before the E5 Broadwells did, and then the E5 Skylake equivalents got delayed forever, presumably in part to finally also support the socketable Xeon Phis Intel wanted so much)
