The Platform

ASUS and Intel partnered up to send us an Arrandale system to test. It's a pre-production K42 notebook.

I won't comment on the build quality because honestly it's not very good. From what ASUS has told me it's already a lot better and we simply have very rough pre-production samples.


As far as I'm concerned, it served its purpose as it gave me a great platform for measuring Arrandale performance.

I compared its performance to an HP Montevina system. Both systems used 4GB of DDR3-1066 and had CPUs running at 2.53GHz. The Core 2 Duo P8700 was our sample from the previous generation and we compared it to the Core i5-540M.

    According to and the idle power is very interesting, lower then the older plataform of around 30%.
    Likely the difference between the two articles is due to a different bios. Moreover Legit has done a lot of tweaks to make the two plataforms comparable (cpu apart). In the battery test, the Monteniva laptop has a 6 cell battery instead of a 8 cell, but the 30% figure seem confirmated.

    One thing I've often wondered about battery tests is variability in the batteries themselves. Of course, over time batteries wear out and life goes down - but what about the difference between new batteries, even ones of the same rated capacities?

    I would be interested to see a review such as this one, but where the battery life is tested twice - swapping batteries between platforms and taking the average. Some adaptation will probably be needed. Or, maybe a standard battery testbench used for all battery life tests - which would involve adapters for each notebook.

    My point is uncertainty. I know it's not an academic paper, but if the variability in results is 10% or higher (which my gut tells me it very well may be with batteries), the conclusions drawn from the results could be radically different. Maybe it's not that bad, and a few tests into the subject would demonstrate that.

    I had">two Gateway laptops that had the same battery design, only one was Intel-based and the other was AMD-based. After a request similar to yours, I swapped the batteries and retested. Variability was less than 2%, which is the same variability between test runs. Reply

    Your unit was obviously just a prototype, but can we expect to see the first Arrendale laptops arriving this or next month? Reply

    love reading your reviews - very insightful. thanks. Reply

    when can we expect reviews of these ULV processors?

    when can we expect laptops with these ULV processors?

    And seriously, wtf was intel thinking with these names? 5 processors, all at different speeds, with either 640 or 620 in the name. If a 620LM was the same speed as a 620UM but just used less power I could see it, but there are 3 processors with 620 in the name, running at 1.06, 2.0, and 2.66GHz. The consumer also has to know that a 620M is faster than a 640LM. Reply

    I'd love to see more comprehensive mobile benchmarks, but it looks like finally Intel graphics isn't the complete crap it used to be. Reply

    On Intel codenames, "Clarksfield" can be easily confused with the desktop "Clarkfield". Reply

    Oops, I mean Clarkdale by Clarkfield. Reply
