Pentium M vs Pentium 4

I was just wondering what accounts for such a huge diffrence in points based upon their GHz numbers.

I have a P4 2.8Ghz with HT turned on and two clients running that puts out about 250 PPD and a Pentium M 1.5Ghz laptop which puts out about 225 PPD. (same WU type)
The P4 also has 512mb DDR2, whereas the laptop has 1200mb DDR.

I know the Pentium M is more efficient, but what accounts for this huge diffrence?
What's also strange is the P4 has SSE3 which the Pentium M does'nt.

And is this also the same concept behind why the AMD's put out far more points in terms of GHz?

~Thanks
 
You might want to take a look at these articles on tomshardware.com :)

"Dothan over Netburst"

37 Watt Pentium M

My understanding is.. yeah, the dothan based off pentium 3 lineage is more efficient per clock cycle than the netburst P4. The articles over at Tom's are really, really quite good. A desktop built around a Pentium M sure looks tasty from a points to KwH perspective.

Cheers,

Ari.

 
The pipeline on the M is much shorter, like that of the pentium 3. It's a perfect time to buy dual/quad p3 machines; they take about as much power and space as a single p4, but with great performance per gHz so to speak.

Okay, so I'm just defending my duallie. I can't wait to get it later today... :D :D
 
Thank's ArionIscariot, those were two good reads. I had seen one review of the Pentium M vs others, but those tests showed it doing very well in games (even the stock 2.13ghz one).

40 watts at idle.... 66 watts at 100%, HA. That's the same as my P2 233mhz with almost nothing in it. Just goes to show how efficient it really is.
