Looking at the evolution of video game consoles is fascinating, while conventional PCs tend evolve ‘incrementally’, new generation of consoles introduce completely new ways of working. What you see here are a series of articles that hopefully will uncover the rationale behind the latest trends in technology.
This is not a developer’s manual, it basically provides an in depth introduction to how each system worked internally. Bear in mind that tech has gotten really complicated lately, so if you struggle to follow my latest articles, try reading the early ones first, it may serve you as an introduction to many concepts and definitions.
Basic knowledge of computing is preferable, however I attempt really hard to adapt my content for wider audiences, so please don’t feel afraid to give it a try!
While I try to be as accurate as possible, if you find any mistakes please give me a shout.
