Interesting article - "The cost of power"

Comparisons between a C2D rig and a Celeron-D rig. Summary: for the same power consumption, the C2D has 4x the output. Correspondingly, a quad-core should likely show the same kind of power/watt gains. (My opinion)

Interesting ,& it follows what I experienced.

I had an XPM 2500 o/c 2.5GHz ,1GB DDR RAM ,S462 Nfrc2 Asus mbrd with an X800XT PE.
This drew ~180w from the wall when running SETI or DPAD.

My rebuild (which uses the same Antec TPII 430 PSU ,2x HDDs ,fans etc) has a C2D E6420 o/c 3.2GHz ,2GB DDR2 RAM, Nfrc 650 MSI mbrd with a X1950 Pro.
Running DPAD this also draws ~180w from the wall! :Q

Oh & my old XPM did about 20,000 Kpts/day for DPAD where as my C2D does about 51,000 Kpts/day (though oddly clock for clock ,on one core ,the XPM was faster! )

Btw he's got cheap electricity ,here in SE England it costs me £13/mth to run this 24/7 ,that's $26!

Inccidently if that Cel D was based on the Prescott core of the P4 then that explains why it's such a power guzzler

Yet another reason for a new built! :evil:

So what is everyone waiting for?! To the fs/t trade forums my legion!

Doing my part for the environment. Got a Q6600@3.0Ghz and a E6420@3.2Ghz! Now to switch out that gas guzzling Pentium 4 M 1.7Ghz for a dual core laptop :evil:

Speaking of that, I wonder why even current budget laptops use a Celeron M chip, which AFAIK doesn't even support speedstep, instead of using a single-core C2D Celeron Conroe-L core, which would be faster and cooler. Maybe Intel just has a stockpile of chips to use up.

Yea probably ,no one wants them!
