Hello Qmaster, Taiidan,

Thank you for the replies. Last day (March 16th, 2017, Thursday) of
Embedded World 2017 I took the trip from Munich to Nuremberg on my own dime
(to visit EW 2017), and to speak with some people/companies I supported
previously (while being "Intel-er", you name it, the support joke), and I
had also the plan to visit AMD booth, so seconds prior I left to Munich
HBf, I sent this email, to see what community will tell.

Interesting talks I had with AMD people. I was able to grab attention of
the most technical guy on the booth, so we had 30 minutes very productive
and lengthy conversation, since I had prepared exact requirements for so
far for implementation of the one of the US patents about efficient RAID
big data storage.

Since I am NOT (per say) AMD guy (unfortunately, still in my sub-conscious
INTEL guy, it is (MUST) changing for the near Future), and I really would
like to embark on their technology since/including RyZen, I have learned a
lot. And what I have learned is about Naples. It is a true killer (if this
is The Truth what they say about it)!

After returning home, that evening, I quickly re-assessed my notes, and
immediately was able to find the real video about Naples:
https://www.youtube.com/watch?v=PN93G6Rg2ek (please, watch it from 1:20)

Naples: True SoC (integrated PCH/Chipset), has 8-channel DDR4 (3.2 GHz
clock speed) memory access, able to bring at maximum of 256GB of DDR4
memory, has PCIe X 128 lanes (overall)... And it'll come June/July 2017
time-frame. No signs of price tag, so far!

And, YES, no way to get rid of AMD Chip-set. Too costly for managing Power
Management/PMIC and far fetched VRs' regulators, although I see that AMD
one is NOT so demanding as INTEL PCH (why it is so, you should ask, whom?)!?

Thank you,
