There's a huge difference here compared to binning: binning generally involves chips that are physically incapable of performing to the higher spec because of defects.
- mlyle 4y agoAs I stated in my comment: this is true at the beginning of a process node with a new design. But yields improve, and eventually you end up with too many parts in the high bins and nowhere near enough in the value bins-- so you end up blowing fuses on parts that test fully OK to make them be 4 cores or 6 cores. (And now, Intel is about to let Xeon customers pay to unlock additional cores...)
- IronWolve 4y agoI was going to mention this also, software defined processors, where you have to pay intel to unlock features. But the original buyer unlocks and sells the PC, it should revert to the stock and limited cpu. Here they gave the owner a 90, then came back and limited it to 60, after the fact, years later.
- mlyle 4y ago> Here they gave the owner a 90, then came back and limited it to 60, after the fact, years later. Yah. And the buyer was a buyer in good faith of a 90 product that no one expected to be snapped down to a 60 artificially afterwards. I agree this is very problematic.
- ericd 4y agoInitially that’s the case, but once the production yield improves, they frequently start gimping large numbers of them.
