The fact that you can get it doesn't mean it's available everywhere. My 
favourite local suppliers don't have them in stock yet, and don't expect 
it for several weeks. Besides, a Pentium-M 1.5GHz runs circles around 
said 1.6GHz Turion64.

My calculations (see below) resulted in a measured TDP of 72W tops, for 
the Winchester 3000+.

I tested CPU power usage by checking individual component power usage, 
total power usage and voltage levels with a power supply modified not to 
regulate voltage levels (of course it was powerful enough, Enermax 
600W). I had to do this because you can't get a definitive reading of 
the motherboard-CPU combo (as opposed to memory, which you can measure 
with load testers and VDDR voltage boosters in different systems, and 
using those values for comparison).

I used various software to get all functional units active, including 
heavy memory switching. Prime95 may be a good tool to benchmark ALU 
performance, it doesn't burn the whole 100% of the processor.

However, this is not relevant at all to the subject at hand. I stick to 
my primary recommendation of a Pentium-M based notebook, with either the 
Intel integrated graphics or the mobile ATi and nVidia offerings.
