First of all, the AXP was never meant to compete with the Revision C northwoods processors. It was made to compete with the Revision B processors. AMD, in a last ditch attempt, upped the FSB of the Barton core to 400mhz to try to compete better, but it didn't do much. Therefore they just lowered prices by a lot. That was the AMD processors major selling point in the AXP era.
Dothan, no matter, how much people want to say it, is no ultimate processor. Yes, very impressive in that it uses so little power. However, it has weak ALUs (Arithmetic Logic Units) and weak FPU (Floating Point Unit) performance. While it is very fast in gaming, it is very slow in Encode/Decode, Mathmatical COpmutations (SuperPi). If Intel were to release this to the desktop they would of course correct all these issues and add all the features such as SSE3, because only drawing 25Watt of power is not a big concern in the desktop market.
Dothan CAN outperform the A64 if clocked high enough. Dothan, though intel will not release it, is thought to have an instruction pipeline somewhere below the length of the A64s, and above the length of the AXP's. THerefore it executes more IPC than the A64, so it doesn't need to scale as high (clockspeed wise) to reach the A64. I would definitely not say it beats the A64, as the only really strong area is gaming and general usage (and of course the superb power draw). A64 is good in all areas not just one or two, which is perfectly acceptable seeing as the Dothan was never meant to be the fastest out there, it was meant to consume the least power while giving the best performance. Additionally, while the Dothans beat the A64's, they barely beat them. If you were to move the resolution up to where normal people play, and crank the IQ settings the performance difference would be next to nothing.
The Turion is not a Dothan killer. It is merely a specially binned A64 that was particularly well constructed and can run at extremely low voltages (30-35Watt). Therefore they will be slower than the regular A64's yet consume ~10Watt more power than Dothan.
Finally, 64bit computing has not faded. It is still very much in the works. However, the market has just shifted to Dual Core processors, and multi-threaded applications. Just give everything time.
