One can stop making wild guesses as far as AMD has voiced the official time frame of the beginning of low-end Ryzen models bulk sale. 6-core CPUs will come out in the 2nd quarter this year, and 4-core Ryzen 3 will be available in the second part of 2017.
Ryzen 5 and Ryzen 3 will possess the similar architecture as their higher-order counterparts. According to some resources, the only nuance is that in Ryzen 3 the SMT technology will be disabled, however, this device will cost less than $149. Ryzen 5 chips will come in at $175–259 (not much for 6 cores with SMT support).
The top-rank sample among 6-core AMD processors is AMD Ryzen 5 1600X offering the 3.6/4.0 GHz frequency rate. It will cost $259, which is only $15–20 more, than Intel Core i5-7600K. Simultaneously, according to pretests results, Ryzen 5 1600X will be 69% more effective in a multi-threaded context.
