When Kumar spoke of 1% yield I would think that he meant that only 1% would operate with the full range of specification required for a part marked 400 MHZ. Including operation at maximum specified chip temperature and minimum supply voltage. When people overclock parts they usually do not operate them at maximum temperature or minimum voltage.

I think that when Jerry Sanders said that hundreds of thousands of 400 Mhz parts would be shipped Q4 along with 4+Million total parts this implies that only 5% (200,000+) need to operate at 400 Mhz. The crux of the issues is whether the "yield" is 1% or 5%. The other 95-99% may be sold but marked at slower speeds.

It seems to me alarmist on the part of Kumar to dwell on this 1% number, even if it is accurate which I doubt, since each fabrication batch may be different and the AMD engineers are working day and night to tweak in the yield to the highest number. Overall 40% to 80% of the K6-2 die are probably packaged and sold.

RE:I work at different chip manufacturers fabs, and I can tell you that I'm sure thier yield is in the range of 40% to 80%.

RE:First, that's a pretty wide guessing range. It's just like being sure that their yield is somewhere between 5% and 95%.

Your obviously a moron thinking 40-80% is like 5-95%.
Stop your stupid responses to real info, you know nothing of these semi companies and their chip making processes.

This is not a wide guessing range when these semi companies keep their EXACT yields private. I'm telling you that their yields are nowear near the 1% that was stated. If their having problems then maybe 40-50%, and if they are going good then about 70-80%. Their yields are not near 1% for the 400MHz chips either.
