Well, which version of the QC die is being used? A0? A1? A2? But even assuming 283 mm^2, that picture gives a shrink factor of only .74 for the core area, if it is outlined correctly. Rev G appears to have an overall shrink factor of about .68 Assuming that roughly, Rev F 512K L2 x 2 parts are 50% core, that might work: 183 mm ^2 --> 91.5 mm^2 of core + 91.5 mm^2 of "other". 91.5 * .74 = 67.7 mm^2 of Rev G core. 125 - 68 = 57 mm^2 of Rev G other. 57 / 91.5 = .62 shrink factor for other stuff Might be roughly what is going on in Rev G, then. So why would the core logic only shrink by 3/4ths? What does that say about the process?

Thanks Hans! Do you know the size of Brisbane? Or can you perhaps give an estimate. I spoke with CJ (he send me a PM concerning this; I'm using some of his figures because they look good). We think Brisbane size could be somewhere along the following lines: Barcelona: 283 L3: 50 Added FP: 8 Stripped QC: 225 (4 cores + 4*512KB + full xbar etc...) Brisbane: 113 (225/2) This is a bit rough as you can't divide xbar etc... by a factor two, but the Barcelona xbar + htt3 ports + added DDR3 logic is WAY bigger than comparable functionality in rev G. We're not clear on it but feel it might be likely that the Inq estimate of 12x mm^2 for Brisbane was wrong. Can you put in the details for us? Regards, Rink
