Emotion Engine

Overview

The Emotion Engine used in Playstation 2 gaming console is a central processing unit developed and manufactured by Sony Computer Entertainment and Toshiba. It was also used in early PlayStation 3 models sold in Japan and North America (Model Numbers CECHAxx & CECHBxx) to provide PlayStation 2 game backward compatibility. Mass production of the Emotion Engine began in 1999 and ended in late 2012 with the discontinuation of the PlayStation 2. The first revision released in retail consoles, CXD9542GB, is known to have been manufactured using a 250nm process, to contain 13.5 millions of transistors and to consume 18 W of power.

There have been die-shrinks and optimizations over the years, but it's unknown at which revisions these happened.
