PM750 1.86GHz vs. Turion MT-34 1.8Ghz= .6GHz differance, slight advantage. So was the video card....
AMD Intel
Core clock 351 MHz 357.75 MHz
Memory 128 MB GDDR3 128 MB GDDR3
Memory clock 297 MHz 344.25 MHz

Spartan, three things:
First, it was a 60Mhz CPU difference, not 600Mhz CPU (you did your math wrong). A .06GHz CPU difference will not make a difference.
Second, as they mentioned in the articles, they overclocked the GPU so that both had matching clocks on both the core and memory. Should I mention what happened to the last guy that didn't read the articles?
Third, both the MT-37 and MT-34 are AMD's 90nm single channel socket 754 mobile chips, and both include SSE3 support. That puts both of them into the same category of chip generation and power management. I knew that higher rated CPU's were higher quality, but to know that they can reach higher speeds at lower power levels than lower quality CPU's is something I didn't think about, until recently.

1/64th is "almost all" in my view.
You are correct about it's impact; that's what Toms article said almost verbatim.
However, the additional 20GB of hard drive space would
not increase power draw, as it only is a higher-density hard drive. IDE/SATA data transfer, higher platter speed, additional cache, NCQ all would increase/decrease power draw, but not data density (actually, in theory, the higher data density drive would have the lower power draw, as the head/actuator would have to travel a smaller distance to retrieve the data needed). If they had a different number of platters, 1 vs 2, for example, that would increase/decrease power draw, as the mechanical complexity would be simpler (if there were just 1 platter) and you wouldn't need as many heads/actuators. But both the Samsung MP0804H and the Toshiba MK6026GAX have 2 platters, so they are about as even as you can get.
