28nm

Im looking for a ps3 super slim with a 28nm RSX for my collection of different ps3 models. I own a 4004 and would sell it for a version with a 28nm RSX, 400x all got 40nm. In some pages on dev wiki they say 4200 COULD be 28nm but also some 40nm only 4300 is for sure 28nm. In other lists 4200s...

Hi, I started this project a while ago and I think it's good to mention it here in case somebody wishes to continue this research. There is a lot of useful data in the video.
