Head on over to AMD.com for the "New Horizon" livestream event taking place at 3PM CST / 21.00 UTC. AMD will be showing off some (Windows) gaming with it as well as allowing the public to try a Zen system for the first time, along with some giveaways and "special guests."
Don't worry if you aren't able to watch it live, I'll post updates on Phoronix if any interesting details are revealed.
Meanwhile, for Linux users, more AMD Zen code is getting lined up for Linux 4.10. Yesterday I commented on some pull requests referencing Zen support and more PRs since then have carried additional Zen code. One of the latest pull requests is Zen in amd64_edac. It ended up being a few hundred lines of code adding Zen / 17h support to the Error Detection and Correction code.
