Elmer - <What isn't a rumor is that Intel has been manufacturing HP processors with 1.5Meg on-die cache for over a year now. Apparently Intel has no such problems manufacturing huge on-die caches. If a company (AMD?) is running their process on the ragged edge you would see two clear signs. #1 they would have to jack up their Vcc to get it to higher frequencies and #2 you would see higher standby or static currents due to sub-threshold leakage currents. This appears to be what the rumors are reporting.>

Yes. Intel and on-die caches do seem to go good together. This is not an accident. A lot of attention goes into process interaction vs. minimum design rule (the cache) in the development stages of the process(es).

I believe an Intel SRAM test vehicle will be featured at next week's ISSCC.

And that 1.5 megs of on-die cache is on a 0.25u process! Think of how much cache can go on a 0.18u die?

(On the other hand, that HP processor is 477 mm2, and makes quite an ornament on the "chip" portfolio I got from MPR last year.)
