For as long as we can remember, Intel has ruled the processor market with impunity, as AMD worked tirelessly to keep up with performance while Intel kept rising its prices. Then Ryzen came out, and everything changed. AMD’s 14nm chips released in late 2016 and started coming out to the public in Spring 2017, promising higher core counts and greater multi-thread performance – while being dramatically more affordable than its competition – AMD delivered.

Throughout 2017, AMD delivered hit after hit starting with the Ryzen 7 1800X, which was a "dramatic return to form" as the company brought back choice, competition and revitalized the processor market. We were even more impressed by the Ryzen 5 1600X for its great price-to-performance and were almost as enthused with the dirt cheap Ryzen 3 1300X. Then AMD dropped its top-end Ryzen Threadripper 1950X, bringing core counts into the high teens at a price dramatically lower than Intel’s competing chips.
