Bristol Ridge APUs were launched today. AM4 socket, DDR4 capable, but it's an updated version of the older architecture, not Zen.

We're already a month into the promised release period of 2H17 for Raven Ridge. Let's hope it comes out closer to the beginning of 2H17 than the end.

We will likely see Zen-based laptops before we see Zen-based standalone APUs, with laptops coming for the holiday season (ie: Oct/Nov) and APUs late 1H18.

I wouldn't mind seeing a good Zen based laptop... Something around an R7 1700 would be nice, maybe 10-20% lower clock for thermals. Something capable of 64gb ram and user serviceable nvme and/or ssd would be great.

There's a decent amount of small form factor Intel stuff on laptop chips (Chromebox, Asus Vivo Mini, etc), if socketed apus aren't forthcoming, that might be something that happens with AMD chips too.

The fact that they announced it as 'second half' as opposed to 'third quarter' should tell you enough.

Anyway, Raven Ridge will be released in laptops first. Desktop Raven Ridge will not be released in desktop formats until 2018.
