Re: Coppermine's on-die cache only transfers data every other clock. (What more do you need when you transfer a full 256-bit cacheline in one gulp?)..

Your post raises an interesting point. I posted here some months ago speculation that the cache added to coppermine(that results in it being competitive with Athlon) may have been "borrowed" from the Willamette design. Which would mean that we've already seen a nice chunk of Willamette's performance improvement.

I know that you (and others) scoffed at that idea, but now you are pointing out that the coppermine cache doesn't make much sense as a match to the PIII core that it's been attached to - are you sure that that cache wasn't taken from Willamette (or Itanium)?

Are you in a position to know such things?
