I have seen these reviews and it is because they released the core duo too soon! Secondly a lot depends on the ram installed ! The centrino has been around for a while and the core duo for all the hype, I have only seen one test where it outperformed the centrino all things being equal.
That was in the new Apple laptop, go figure!
I am looking to buy a new 'thin and light' notebook. I have been reading the reviews, and the Dell XPS M140 (with the regular pentium m processor) is at the top of the charts in both performance and battery life according to the BAPCo MobileMark 2005. The M140 had a performance score of 238 and battery life of 354.
Yet the HP Pavillion dv1000t (with the new Core Duo processor) had lower scores. The dv1000t had both a performance score of 232 and battery life of 232. The performance is only 6 points shy of the M140 (238-232=6) but the battery life is 122 less (354-232=122).
Here is a link the the review I am talking about...
I was reading a review of the new Core Duo processor. And it is supposed to give a performance increase of approx. 30% while reducing power consumption by nearly 30%.
Here is a link the that review...
So my question is... Why is the single core M140 out performing the dual core dv1000t in every category?
