Tim, Re: "Assumeing this is true why can't AMD also push their .13 process the same way they pushed their .18?"

I have no doubt that AMD will continue to tweak their processes, even at the .13u level. But you must realize that this does not come overnight. Gate widths below the 70nm level (which is the size of publicly published .13u processes) require much smaller lithography than what is available in volume today. 193nm machines are the ones that should have been shipped this year already, but which were delayed. Given the proper phase shifting technology, which is only available right now (in high volume) for 248nm lithography, the 193nm machines should allow for smaller dimensions. But since neither the machines, nor the phase shift technology will be available in high volume for quite some time, don't expect AMD to have an enhanced .13u process right off the bat. For more information on future lithographies, Intel has a very good presentation here.

intel.com

If you check out page 14, you'll see that 193nm has been confirmed to scale down to the 100nm node (with 50nm transistor gate length), so I don't doubt that AMD will make use of these features eventually. In the beginning, though, you should not be assuming that AMD's .13u process will have a large benefit over their .18u process, which is already using .13u tricks.
