No, these kinda specs are for the geekest of tech freaks. lol. They don't need to mention it anywhere - just like you won't find a falcon or jasper written anywhere on a 360 box.Thanks
But I couldn't find 45nm is written on PS3 and it's box. BTW, what does nm stand for? And what do u mean by "if it's a PS3, it is safe", any doubt? lol
nm stands for nanometer. It basically means the width of the smallest "wire" on a CPU die.
