Not 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 which means it couldn't really be 5% but binned

Also 5% are usually carbon while 1% are metal film so no, try again.
