Sorry but after the amazing Athlon x2, the core and core 2 (then i series) lines fuckin wrecked AMD for YEARS. Ryzen took the belt back but AMD was absolutely wrecked through the core and i series.

tl:dr: AMD sucked ass for value and performance between core 2 and Ryzen, then became amazing again after Ryzen was released.
