Do you know ICE TEAM? So they are simply the developers of the developers, they who structured a PS3, PS4 API, but also PS5 ... So according to these developers Cell did not have a GPU until 2004, so if you can argue with NaughtDog's ICE TEAM. .
"For a while, [PS3 had] no GPU, it was going to run everything with SPUs. The ICE team proved to Japan that it was just impossible. It would be ridiculous. Performance-wise, it would be a disaster. That's why they finally added the GPU, closer to the end."
Another source confirmed that, during the delay, Sony was "still trying to figure out the hardware" it was creating, and mimicked the notion that "for a while, it didn't even have a GPU," hence the delay. It's important to note that, before PlayStation 3 was even named, there were very early rumors that it may launch in 2005, but by the time it was officially revealed at E3 2005, an accelerated release schedule was likely already abandoned.
In a conversation with multiple sources associated with Naughty Dog, IGN can today confirm that the PlayStation 3 was supposed to launch in 2005 and was delayed by a year.
