Huh, it appears that Intel could make their press deck a bit more clear. The one regarding the Xeon Phi mentions 'high bandwidth memory'. At first glance I thought that was referring to the same HBM technology on the Fury X but all the specs indicate that it actually uses HMC, a similar competitor. Of course the reality is that Intel is using high bandwidth memory generically here but it is confusing.
Because HBM means high bandwidth memory. It's not a specific definition last I checked. WideIO, HMC, and die stacking RAM over a wide bus are all types of HBM. Just someone(s) decided naming one HBM was smart. For some weird reason.

Free publicity. Every time someone decides to refer to one of these technologies generically, people think of HBM (the GPU specific implementation). People post questions in forums. Others post answers to straighten out misunderstands. Some even make post about the potential merits of HBM that isn't even in use in the topic of discussion. Then lots of others read the post. Finally, someone makes a post about how all this works to bring publicity to the technology. That's just the forum post version of getting publicity.

It doesn't help HMC was actually the first "high-bandwidth memory" designed and was deployed back in 2013 for the Oracle Sparc Fujitsu systems.testbug00 - Monday, November 16, 2015 - link

I believe it is more closely related to the Micron HMC than the Hynix HBM on the Fury.nikaldro - Monday, November 16, 2015 - link
HMC isn't really a competitor to HBM. They're meant to bite completely different markets.aaa123 - Friday, November 20, 2015 - link
what a crap. intel really sucks. mellanox and nvidia are at least3 years in front of them. the landing
is around 20% behind latest nv on
single prec.
