Tony
does k6 violates laws of nature then since k6 proved to be reliable chip?

Tony,

For the fifteenth time, bad yield and poor reliability are synonymous.

Of all the things in the computer, the reliability of the CPU is about the last thing you need to worry about. That's because the CPU's are a lot more reliable than other hardware components. And there is no comparison between hardware and software. The software and various software drivers for hardware are most often the source of problems.

Maybe you should talk to MIS support group in a large company. Why don't you ask them how many problems are related to failure of the CPU.

I think you would do a lot better as a salesman selling computer stuff to newbies. Your FUD may work on them.

Joe

PS: I didn't see anything on the label of Pentium, K6 or Cyrix chip stating their yields. How can I find out (accurately and reliably) the yield of the CPU I am about to buy?

Tony, <bad yield and poor reliability are synonymous...>
Do you imply that people at IBM and Compaq are less
educated in reliability issues than you (BSEE)? In
another perspective, all your rant is irrelevant
becasue in REALITY the chip comes with 1-year
warranty at least. Even more, who cares about it when
a system is under a service contract from Compaq or IBM?

<pick up a book on semiconductor reliability, or go
to a technical library, at any local college or
university that has a technical curriculum, find
such a book and read it for yourself.> I would think
that at 49 and in a managerial position you should
already learn the difference between a college
book and a business reality.

Tony - Re: "Low yield and Poor Reliability"

For a marginal process with low yields, even the "good" chips will be on the "edge" as far as proper processing.

For a high level of defects, defect "clustering" is a common characteristic. Latent defects can exist on "good" chips - the defects not being initially catastrophic.

Over time, those defects - gate oxide pin holes, contaminants left between thin film layers, etc. - can grow or migrate eventually causing the once functional chip to die an untimely death.
