| And that little extra question - does the same sspec exist with both small and large die cap? |

Which question did you answer, John? The one about octagonal die caps or the one about same sspec, different caps?  |

Yes, but not on Celerons. Early Pentium IIs (Klamath) have the same octagonal die cap. The cache chips of Pentium II Xeon and Pentium II Overdrives also have the octagonal die caps (with two less capacitors than that Celeron box pic.
I suspect that the photo on that box may be an early ES or mech using a PII die (or a PII package at least). Maybe the idea for Celerons came about from Intel having numbers of PII dies with defective L2 cache?

Yeah, I can see what you mean from the caches. Good point!

Well, but no Celeron was ever built on 0.35um technology - and what would be the problem with defective L2 - it wasn't on-die anyways .. |

Silly me, had forgotten that! You are right. On die cache started with the Mendicino Celerons. Maybe that pic was just a marketing pic made up for the box.

They are either mendocino dies with the cache disabled, or a Covington die in a mendocino package

| Are there really Covington dies or is it just Deschutes die without external cache? |

If same sspec, shouldn't the internals be the same? |

Yeah, when you asking, I was wondering, how difficult it is to open one to expose the die for you to photograph.
Unfortunately, I only own 2 Covingtons - both small cap - and I think they might begin to be too rare to actually open one? |
