AMD Ryzen 5 and Ryzen 3 CPUs come later
 

Q2 for Ryzen 5 and 2H 2017 for Ryzen 3

It appears that we will have to wait a bit for the rest of the Ryzen lineup as, according to AMD, six-core and quad-core parts will be coming sometime in the second quarter and the second half of this year.

While its octa-core Ryzen 7 lineup is already up for pre-order with availability expected on March 2nd, the rest of the lineup will be coming later, with six-core Ryzen 5 lineup, which should compete with Intel's Core i5 Kaby Lake lineup, coming in Q2 2017, and the quad-core Ryzen 3 lineup coming sometime in the 2H 2017.
