Today, AMD is celebrating 5 years of Ryzen CPUs which not only disrupted the entire segment but made AMD the undisputed king of the mainstream and enthusiast segments.

Yes, it's now 5 years since AMD released its first information on its Zen core architecture that would go on to power it's Ryzen CPUs. Everyone was excited about AMD's Zen which was being developed under the leadership of AMD's CEO, Lisa Su, and by legendary chip architect, Jim Keller. Ryzen CPUs changed everything when they launched and each iteration brought even better performance and new features which were unlike what their competitor was doing. Even the likes of Zen+ and Zen 3 which weren't meant to be major architectural overhauls ended up bringing a significant amount of performance improvements.
