Re: Nothing has been proven except perhaps the die size of a Celeron 200. It's almost certainly a fused dual-core Core 2 of the smallest 1MB kind which could quite easily fit into that die size. Then what is the die being used for the measurements on slide 32? download.intel.com C1 = 7.4mm C2 = 10.9mm Die size = 80.66 mm^2. Like I said, you need to account for the thickness of the epoxy on the Celeron 220 datasheet. This seems to be the size of the bare single core die, on yet another Intel product line. Note, too, that this product line uses some parts from a fused dual core part as well. So maybe you have it partially right that the Celeron series is a dumping ground for defective dual core die, but in the end, there are obviously enough volumes of single core that Intel developed an 81mm^2 Millville core to consume it. If Intel were losing a large percentage of dual core die to defects, they wouldn't have needed to develop a native single core die. Furthermore, there is no evidence to say whether the fused parts are defective, or whether it's just downbinning to supply necessary volumes. There's no data as to the percentages of fused vs. native single cores, either. So it's mostly conjecture, and up for speculation. The only thing we know today is that AMD has commented publicly that they intend to use defective quad core die to supply triple core volumes, while Intel said publicly that they do not do this. So it's really up to whether you believe them or not. The data does not prove it either way. It does, however, prove that Intel has made a single core variety, which at the very least is used in the Celeron 500 series, as well as the Celeron 220.
