The evolution of AMD Ryzen processors

Posted by Stefan on 2022-09-06

The AMD Ryzen processors are designed for the mid to high-end range and are grouped into the Ryzen 3, Ryzen 5, Ryzen 7 and Ryzen 9 classes. AMD follows the market leader Intel, which groups its Core i series (Intel Core i3, Core i5, Core i7 and Core i9) identically.

The AMD Ryzen processors were first introduced by AMD in Q1 2017. They are the successor to the not particularly successful AMD Bulldozer processors. The latter were manufactured using an outdated manufacturing process and could not keep up with the competing products from Intel. AMD lost a large portion of its desktop processor market share during this period.
