I don't think your correction is accurate. If you look at a PS2 mobo, the chip labeled the Emotion Engine is the CPU. The "Graphics Synthesizer" is a separate chip. You can see this on the Wikipedia article on the Emotion Engine [0], which also identifies it as a CPU. It cites an article [1] from early 1999 - around a year before the Japanese launch - which maintains the same naming scheme.
It's possible that at some point in development Sony was calling the GPU the Emotion Engine, and then renamed it to the GS but liked the Emotion Engine name so much that they started calling the CPU the EE, but that seems a little unlikely...and either way, the article is accurate in terms of how things ended up in production.

- tenebrisalietum 4y agoPS2 was unique. EE was the CPU, but it had two programmable vector units as MIPS coprocessors or something like that. VU0 could talk to VU1, and VU1 could talk to the GS directly. I think their job was generating "display lists" for the GS to follow and draw per frame. GS might be more accurately called a rasterizer/TMU. https://www.copetti.org/writings/consoles/playstation-2/ https://www.copetti.org/writings/consoles/playstation-2/
