Ryzen 7 1700X is meant to fill in the gap between the 1800X flagship and the 65W-rated Ryzen 7 1700, at an affordable price point of just $399. This SKU borrows all the features from the more expensive variant, including the 100MHz XFR, but is clocked lower by default at about 3.4GHz (3.5GHz with XFR) with a Precision Boost up to 3.8GHz (3.9GHz with XFR). With this CPU, we were also finally able to hit the all-core “magical” 4GHz mark, a result that did increase the performance even more at only 1.393V, right from Ryzen Master! Link
