AHHHHhhhaaaa!!!
Finally !!, after 23 posts, revealed results from the "In House Press Conference"
The results are from AMCC Twitter page,
by Caroline Hayes@ElectronicRuiva " Applied Micro says its ARM-based processors beat MIPS and PowerPC in enterprise servers".
It's about time,
" The benefits of Applied Micro's ARM-based multi-core processors, the Helix 2 embedded SoCs were revealed by John Williams, VP marketing, at a euroasia press briefing at the company's offices in Sunnyvale, California."

phobos, maybe you can translate and explain in DETAIL how this will ALL benefit AMCC, thanks
PAM4 (pulse amplitude modulation 4) is a way of instead of sending more information per binary digit besides just increasing the bit rate. Typically the bits can be either "0" or "1", but with PAM4 each bit can be 0, 1, 2, or 3, so it is a ternary scheme instead of a binary scheme.
Below is an eye pattern for a binary scheme:

Below is the eye pattern for a PAM4 signal:

Below are some news stories about the PAM4 signal and Inphi and Broadcom (now Avago), are the only two companies currently with PAM4 chips. Inphi is the only company with a 400G PAM4 chip. The Broadcom chip is 100G. PAM4 is the newest interconnect coding scheme for the data center. AMCC seems to be keeping up quite nicely.

I would still rather hear about AMCC sampling X-Gene 3, but this is good too.
From an article about one year ago (http://www.enterprisetech.com/2014/08/12/applied-micro-plots-x-gene-arm-server-future/)
"Further down the road, Applied Micro is readying its “Skylark” X-Gene3 processor for sampling in 2015. This chip will sport a third generation ARMv8 core designed by Applied Micro, with microarchitecture enhancements as well as a shift to TSMC’s 16 nanometer FinFET 3D transistor technology. The chip will include a substantially upgraded on-chip coherent network and also inter-rack connectivity of some sort – Applied Micro is not being specific. The X-Gene3 SoC will have from 16 to 64 cores running at a baseline clock speed of 3 GHz. The power envelope will rise, given all of those cores, but the performance is going to go way up, too. Singh says that other server chip makers will be “the pipe cleaners” for the 16 nanometer FinFET process and by the time it is ready to do sampling around the middle of 2015 it will be a mature process with the kinks worked out."
