Elmer, Since we can't get any decent yield estimates out of you Intelaffooons we'll just use the low 70's as a good starting point. Paul even said that that number was about right a while ago and that it is probably higher now. Do you have a more exact number? The slot one packaging does cost more doesn't it? Figuring cost is basically a relative thing. Depends on what you include in "cost". More important is that you figure the relative cost of the K6 and Celeron using the same cost factors. If you can do that, based on die size, relative yields (K6 gives up some here but the die size more than makes up for it) and packaging (costs more to package a celeron), the cost of a K6 is considerably less than a Celeron A. By my estimates it's cheaper by about a .7 ratio. Where the Celeron would cost 50 and the K6-2 would cost 35 or some ratio there of. Maxwell says 64 vs 45. This is also a .7 ratio. Jim

Elmer, I would think yields in the 70% area are very good and hard to achieve. The Celeron package is far more costly then the K6 pachage and the yields for AMD and Intel must be similar? So celeron costs more by the slot type package premium. when 370 comes along Celeron costs will drop to a bit more than the K6 costs. Remember when they all transitioned to plastice packages? When will that come along for K6-2-3, and K7? if ever. I am aware of the better thermal ratings of the metal/ceramic package, however lower voltages and die size shrink heat out even as the ever faster hotter chips make the heat go up. As they get better plastic thermal conductivities will they reach a plastic point for the K6-2-3, Celeron 333? This will save a bundle. I recall when the 286 went plastic, price dropped. Bill
