Need to fix power first
The current prescott design draws a fair amount of power. When 64b is enabled, I suspect the power will go up a bit. I think Intel needs to reduce power consumption before they can think about implementing features that will raise it.
Xeon has always been specified with a higher power budget than Pentium, so I suspect they can hit the Xeon targets with 64b enabled, but this does not guarantee they are ready for the desktop... yet...

sonic, bottom line A64 beats Prescott on 32/64 bits
We already know AMD wins the vast majority of benchmarks against Prescott on 32 bit applications. It's only going to be a larger margin for AMD on 64 bits because AMD uses Hypertransport which blows away Intel's FSB, and also AMD chips have an on chip memory controller. Intel chips will have bottleneck problems compared to AMD because of these 2 factors and Intel chips will fall even further behind AMD's at 64 bits. Throw in the latency penalties for Intel Prescott's having a 30+ stage pipeline and their use of L3 cache and it only gets better for AMD at 64bits. Cha-ching.
