Raystonn, an Intel employee that occasionally posts over on Hardocp forum, has offered up a nice piece of info...
"Actually, every single processor is tested for the maximum reliable clockspeed, not just a few in a batch. The tests are started at the maximum clockspeed at which that processor is currently being sold. If it does not pass, it is retested at the next lower clockspeed at which it can be sold, etc. If it fails at the lowest clockspeed at which it can be sold, it is tossed in the garbage.
Once the maximum reliable clockspeed has been determined, the sales department comes into play. Sales indicates they need W number of 2.2GHz processors, X number of 2GHz processors, Y of the 1.8GHz, and Z of the 1.6GHz. If they do not have enough processors to come up with Z 1.6GHz processors, they take one of those that passed at a higher clockspeed, and mark it down to 1.6GHz.
What all of this means is the following:
- If you buy the highest clocked processor currently available, there is no telling high much higher it can go. It was only tested at that one clockspeed and it passed. It may be capable of running reliably at twice that clockspeed. These tend to make some of the best overclocks, but "you pays your money, you takes your chances."
- If you buy a 1.6GHz processor, you may in fact be buying a processor that passed all tests at 2.2GHz and was simply marked down to 1.6GHz because it needed more of them at this clockspeed. There is no way to tell without pushing up the clockspeed and trying it out. There is always the chance that your processor only passed at 1.6GHz, so you might be out of luck. It depends on the processor. However, as time passes yields improve. There may not be any processors at all that failed all the way down the line until they hit 1.6GHz. In this case, every single 1.6GHz processor sold would be capable of higher clockspeeds. Again, "you pays your money, you takes your chances."
Now you might be wondering why the sales department would want a processor to be sold at 1.6GHz instead of 2.2GHz. Well, say they have plenty of 2.2GHz processors on the market. Everyone who has requested such processors has received their shipments and are very happy. Producing more of them will not produce more sales. However, there is a market still untapped at a lower price point. Producing these 1.6GHz processors could lead to more sales. A sold 1.6GHz processor has produced more income than an unsold 2.2GHz processor.

I haven' t gotten the CPU yet...should have it by Saturday. Do XP:s have "stepping" like the Athlon C's?
