Yesterday there was a fourth quarter earnings call today, with the results showing a few posts below this one. In this call AMD CEO Lisa Su confirmed that the consumer Ryzen CPU lineup will be available in early March. 

The server based lineup code named tagged under Naples will launch in the second quarter of 2017. The AMD Zen based APU code named Raven Ridge (mainstream SKUs) are scheduled for launch in the second half of 2017.

“Yes, if you look at our product lineup in the first half of the year, I think we have Ryzen launching in early March, and then we will have Vega, our enthusiast GPU, launching in the second quarter. And so as we go through the year, I think we are quite pleased with the performance that we are seeing on both of those products. And so we should see Ryzen doing very well in the high end as well as Vega. And by nature, since both of those high-end markets are markets that we don't have significant presence today, there will be an opportunity to both gain share as well as increase attach rates in those markets.”

Vega was mentioned as well, the Vega lineup will launch in the second quarter of 2017. So that is the April, May June time frame. The Ryzen processors and platform will be available from day one Su also stated. 

“There will be widespread system availability from day one,” Su said during the call. Channel vendors will receive the first Ryzen chips, along with system integrators. More traditional hardware vendors will come later, Su added.
