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.

Without further ado, here they are!

3rd generation

Known as '8-bit' consoles, these machines brought more sophisticated graphics and sound than its predecessors. After all, a big market crash just occurred and newer standards had to be set.

Outstanding GPU features: Scrollable Tile maps and larger colour palettes.

4th generation

DMA, horizontal interrupts, multiple modes... These are some examples of the new concepts that brought the new '16-bit' generation, opening the door to new genres of games.

Notable CPU advancements: Wide address buses and dual-processing.
Outstanding GPU features: Affine transformations and Horizontal interrupts.

5th generation

3D gaming has become a need but 'how' is not clear yet. The response? Every company presented their own different vision.

Notable CPU advancements: Pipeline stages and L1 cache.
Outstanding GPU features: Vertex-programmable 3D engines.

6th generation

Most of the graphics limitations from the previous generation are no more. Portable consoles start to resemble familiar systems.

Notable CPU advancements: Superscalar architectures and SIMD instructions.
Outstanding GPU features: Pixel-programmable 3D pipelines and anisotropic filters.

7th generation

Consoles have become multimedia platforms, this machines are now more capable than just playing games, which is why security is now a critical factor.
