Texas, my understanding on the .13 process was that the process transition was fine, but that something was overlooked in doing the actual CPU shrink that set things back a little for the TBred in particular. This only hurt performance of the chips being produced, with chips having relatively low speed grades for a die shrink. I believe AMD may have been using some of those earlier chips for the mobile market so it's no biggie.
As for Hammer rumors, the board makers and even the chipset developers have all only been given earlier hammer revs amounting to a real world 800 mhz chip (still outperforms a P4 1.6ghz running Quake 3 if Tech Channel is to be believed. So, double that real world speed in mhz and add some significant performance tuning and ewven running at 1.6ghz, the Hammer should outpefrorm any ther desktop CPU. However, I will reserve my full enthusiasm until I see more up to date benchmarks...from more than one site..on a hammer and motherboard/chipset closer to production ready.
