If this surprises you, I've got some bad news for you. Everyone does binning. Go buy 1000 5% resistors and test them. Instead of a normal distribution of tolerances, you'll find that there's an interesting trough around -2% to +2%. That's because all of the resistors are made using the same process and the lower tolerance ones are binned and sold at a higher price.
Same goes for silicon. The dies are largely the same. Only later in the process, they get binned to a lower spec cpu by selectively disabling features. Generally, this is because the chip doesn't meet some spec, but there are cases where this is simple done to meet demand.
- ilyt 4y agoNot talking about binning, but getting previous generation of core in your "new" CPU. >Go buy 1000 5% resistors and test them. Instead of a normal distribution of tolerances, you'll find that there's an interesting trough around -2% to +2%. EEVBLog tested the 1% ones and it had gaussian https://www.youtube.com/watch?v=1WAhTdWErrU https://www.youtube.com/watch?v=1WAhTdWErrU which means it couldn't really be 5% but binned Also 5% are usually carbon while 1% are metal film so no, try again.
- dschuler 4y agoThe top comment in the video mentions someone's experience with resistor binning with a batch of 10% resistors having no samples under 5%. Anyway, the resistors binned for tighter tolerances aren't going to have to have a trough in the center of the distribution - they'll have cutoffs on either side. Binnig can be repeated for any tolerance desired, so carbon vs metal film doesn't have anything to do with it.
