"There is no difference between the last 90nm transistor and the first 65nm transistor."

OK, I'll admit my ignorance here... I was under the impression that AMD typically shrinks the transistor size down a process prior to shrinking the rest of the manufacturing process. However, this is the first time that I've remembered AMD going on record as stating that the next process shrink will START at mature yields. I know I remember AMD touting how quickly they ramped to mature yields in the past.

My point was that, whatever we might think about manufacturing at AMD, if they START 65nm out of the gate at mature yields, this will be impressive and will also imply that they made the tradeoff NOT to start 65nm earlier so as to maximize production and NOT because of any yield problems...

"I thought this was beaten to death a long time ago. There is no difference between the last 90nm transistor and the first 65nm transistor."
Oh, yes there is, the 65nm is smaller ;).
That will give more room to offer bigger L2 cache. You may not have noticed but some of the benchmarks strongly indicate that Conroe is beating Athlon because it has twice the cache.

Bob,

There is no difference between the last 90nm transistor and the first 65nm transistor. That is what AMD has been saying for a couple years.

That may be true, but metal layers stay the same. It is not until those shrink, that the chips will shrink.

With X2 percentage growing, AMD needs to shrink their die size for capacity and cost reasons.

Yes, while the characteristics of the individual transistor, eg; gate length evolves, the die size remains the same till the over all footprint change, generation transition.

The transistor evolution eases the transition.

According to my limited understanding, the measure, relates to "wire width", eg' 90 - 65nm. Where "wire width" is the metal circuitry burnished into the etched si.

Thats my interpretation. I sure don't mean to condescend and you probably know more on this subject than me. Just for the readers out there.
