I found this posted on another hardware forum and would like to know if this is true or not. I personally was very shocked at this as I beleived that processors were specifically designed with great detail and care to exact specifictions in order to determine the clock speeds.

All chips on the same core design are the same. That is to say, any Thunderbird core chip, of any speed or packaging (slot or socket) is the same design. Some will run faster than others, as the production process improves, and some are flukes.
As the production process improves (purer, less dust in the cleanrooms, etc), the chips run faster. Chips are "binned", based on the speeds they will run stably, and the ones that are stable at higher speeds are sold as such.
However, only one chip from each wafer (which could be a hundred or more) is tested, and so some will be faster, some will be slower. AMD's binning is very consistent and conservative, so most AMDs will run 200MHz over clock, and some much beyond that. Intel's binning is not so good, so some chips won't overclock at all (and some are even unstable at stock speeds), while others will achieve amazing overclocks.
The same process applies to graphics card chips. For example, GeForce 4 Ti chips. The best become Ti4600s, the less good ones Ti4400s and the worst ones Ti4200s.
Is this true or just someones imagination in overdrive. ??
