Re: "I guess you should know since you do work at an Intel fab"

I do not work at an Intel fab however I do visit them occasionally.

Re: "But the article said, 'On the Celerons, however, Intel is disabling half of the cache and likely running it at a slower speed, so the chip can only take advantage of 128KB of the cache'

What is the sensible reason for disabling half the cache? Demand is good?"

Intel needs a product to fit the Market formerly held by the PII version of Celeron. I'm kind of surprised they are using the same die as CuMine because I expected them to use a seperate die and save the realestate but I guess they decided otherwise.

If you are wondering why they aren't actually defective CuMines, there are a bunch of reasons but the simplist is that they just don't get nearly enough defective CuMines, let alone L2 specific defects, to meet the demand for Celerons and they have to plan well in advance to (hopefully) meet the demand. There has been talk of K6-2+s being K6-3s with defective L2s. If this is true, and I don't know that it is, then it really brings into question AMD's die cost structure. If they have enough defective parts to actually recover some in this fashion and productize them, then they have a very high defect rate and many more parts must be unrecoverable. I don't know this to be true but I'm just commenting on reports.
