"GS" stands for Graphics Synthesizer. It's the PlayStation®2's co-processor that's responsible for rendering the graphics (but is also used by some games for additional calculations and other purposes). It runs at half of the Emotion Engine's Clock speed at 147.456 MHz.
Also known short as GS.


The first revision released, CXD2934GB, is known to have been manufactured using a 180 nm process and to consume 19 W of power (calculated from the official information that the initially released [[Emotion Engine]] consumed 18 W of power and that EE and GS together initially consumed 37 W of power).
