Brian, have you noticed that everytime I mention die size, the Intelosers get very defensive. Whether the Intel Tillamook is 80 mm^2 or 95 mm^2 is pretty insignificant when the AMD equivalent is 68 mm^2 and faster besides. This is a big switch from '97 when the K6 die size was much bigger than the Intel P55C (162 mm^2 vs. 120 mm^2). BTW, can you guess how many AMD Fab 25's it would take to produce 100M K6's, with 60% of them K6-3D's, assuming 50% yield using the 0.25 process? 3000 wafers/week * (31400 area/wafer) / (81 mm area/K6-3D) 0.9 0.5 yield * 52 weeks/year = 27.2M K6-3D CPU's + 2000 wafers/week * (31400 area/wafer) / (68 mm area/K6) 0.95 0.5 yield * 52 weeks/year = 22.8M K6 CPU's So one Fab 25 at 50% yield could make 50 million CPU's. I think thats quite impressive, considering the entire x86 CPU market for '98 is only 100 million! Petz
