The shop is having it in storage.
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.
I gave you evicence on the validiy of these number, what you give me is
a vague expectation based on nothing... please back up your claims with
numbers, or don't claim anything.
My calculations (see below) resulted in a measured TDP of 72W tops, for
the Winchester 3000+.
Official TDP by AMD: 67 Watt
Testet with Prime95: 38.65 Watt
If you look at the old Athlon64 3500+, you will notice AMD's TDP is set
at 89, the test measured 59.32. Same goes for the FX-55 offical number
is 104Watts, and measured in this test 72.99...
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.
