Re: Add something intelligent to the conversation or stop wasting bandwidth

OK, you keep saying AMD has already "shown its hand" with a hybrid .18/.13 process. I couldn't find anything on that - no references that I could track down.

But I did find that while Intel's .18 was originally defined as...

intel 
process         Circuit Gate
generation Year size    length    CPU 
P648       1989 1.00    micron    486 
P650       1991 0.80    micron    Pentium (60..66MHz) 
P852       1993 0.50  0.50 micron Pentium (75..266MHz) 
P854       1995 0.35  0.35 micron Pentium Pro 
P856       1997 0.25  0.20 micron Pentium II 
P858       1999 0.18  0.13 micron Pentium III / 4 
P860       2001 0.13  0.07 micron Tualatin / Northwood 
P1262      2003 0.10  0.05 micron  
P1264      2005 0.07  0.03 micron

...they later switched to a "hybrid" .18 with 0.10 gate lengths instead of 0.13 gate lengths to get to 1GHZ on P3 and 1.7GHZ on P4:

Intel's 0.18-micron process technology normally produces transistors with a 0.13-micron gate length, but in his presentation Ghani said a method had been devised that allowed a notch to be introduced at the bottom of each transistor's polysilicon gate, thereby narrowing the gate length to 100 nm.

Maybe that's why the big move to .13 and copper only takes P3 from 1GHZ to 1.26GHZ and P4 from 1.9 to 2.4GHZ - it's really more like a move from .15 to .13 than .18 to .13.

But AMD expects the move from .18 A4 to SOI .13 A4 to take it from 1.7GHZ to 2.8GHZ.

Is that better?
