>> AMD is going to attempt to improve their 65nm transistors in 2007, as the quarters roll by

But haven't they been working on that for two years ? The design was very successful at 90 nm. Apparently it just isn't compatible with the process they're using for 65 nm. (I don't have the slightest idea what that means).

A while ago, Dan3 pointed out to me that Intel P4 extreme at 90 nm was clocked at 3.8 GHz. But the P4 extreme in 65 nm, was clocked at 3.6 GHz. Presumably because Intel just couldn't push the design further.

I think the same has happened with AMD's 90nm->65nm effort. They likely need a different transistor design. (I don't have the slightest idea what that means, either).

But could it be that these designs (whatever works well in 65 nm), because they are new, might be locked up with patents, and maybe there are not many ways of getting the job done ?

Also, a lot of time has been used up, and possibly there is not a lot of time remaining to do a new design for mid-'07 ? I just think that if there was something left in the tweak tool kit, they would have tried it by now.

Of course AMD could have, a while back, started working on something totally different for K8L, that doesn't have the issue of low clock.
