At Tokyo Game Show 2013 press conference, Sony revealed that original Playstation 4 design had only 4GB GDDR5 RAM and it was “business decision” to upgrade from 4GB to 8GB, according to SCE president of Worldwide Studios Shuhei Yoshida.
“And because we chose expensive memory…we really liked the performance, but it’s pricy, right? So going to 8GB was a bit of a business decision,”
“But we were able to make that decision because of a lot of the feedback from developers”, Yoshida said in a recent interview to GameSpot.
