"You must have sharp eyes, I can't see anything specific in
the AMD slides ..."

Rink has a point. There is a noticeable gap between the L2 and the core logic, along with the structure that the guy identifies as "L2 OOO Read/Write Buffer" that doesn't exist on the Rev. F micrograph. In addition, there is a strange area where the "mysterious purple block" is. And it still doesn't look like logic.

So, what is it? A shot of the non-production chips? A shot of Rev. G?

Another thing, does it seem strange to anyone else that they have a non-production test chip with added logic? Don't get me wrong, AMD has in the past done chips not intended for production as a test on a new process, I remember the excitement of the news over 180nm, copper K6s. But the whole point of these test chips is to use something with known characteristics, like a K6 design, change only the variables related to the new process so as to get an idea of how the process is doing. Seems to me that introducing new logic sort of screws the concept up. So what were they testing? New ideas? Isn't that what they have simulators for? I mean, if they are burning through millions of dollars every time they want to test some new ideas....

I am wondering if the whole "non-production test chip" is some sort of red herring.
