1.3 Centrino vs. 1.6 Centrino

[bharok]

Are there any benchmarks comparing laptops containing 1.3 Pentium-M and the 1.6 Pentium-M with the rest of the specs the same (GPU, etc).
I want to get a T40 and am not sure where to get the

237358U which has 1.30GHz Pentium M, 256MB ram, 30GB hard drive, SXGA, 32MB ATI Mobility RADEON 9000, DVD-ROM, and Wi-Fi wireless upgradable

and get a buy a cdrw, minipci wifi card, and ram afterwards or to just get the

2373-92U which has 1.60GHz Pentium M, 512MB ram, 80GB hard drive, SXGA, 32MB ATI Mobility RADEON 9000, CDRW/DVD-ROM, and 802.11a/b

Thanks,

My friend has a Toshiba Tecra S1 with 1.6 M , and I currently am using a T-40 1.3M . The two laptops have very similar specs (both with 32 mb v card, and a 30 gig HD, 512 mb or rams), however the performance is very close in games and normal applications.

There isn't much of a difference. There is probrably more noticeable difference in the 1.7 to 1.3, but 300 MHz is close these days.

Since some tests claim the Pentium M 1.6Ghz performs like a Pentium 4m 2.4Ghz, does that put the Pentium M 1.3Ghz around Pentium 4m 1.8 - 2Ghz speeds? Or where? Since Pentium M chips are supposed to have relatively more bang per Mhz than Pentium 4m chips, doesn't that mean each 100Mhz speed difference between Pentium M chips is a more significant performance difference?

It depends what your purpose is with your laptop. For everyday use, I'm there is isn't too much of a noticeable difference especially if you're running the notebook off of battery power. Most of the time, the CPU will be speed stepping to a lower setting for CPU power use you'll likely need. (Unless of course you change the settings to have the cpu run full throttle all the time)

As some previous posters have mentioned, there is a relative comparision how a 1.3m runs in the neighborhood of a P4 1.8 and a 1.6m runs in the neighborhood or slightly above a P4 2.4 With that said, yes there will be a difference in certain games, heavy duty MP3/video encoding, etc.. Between the 2 laptops you mentioned, I believe the biggest difference in speed will simply be due to the fact that the second system comes with 512 memory vs 256.

I believe PCWorld had a listing of the Ms they benchmarked on a past review a couple months ago. For gaming purposes, simply goto 3DMark's site and type in the info under search, and you'll get a solid idea on what the differences would be.

Best of luck, and either way you're getting a nice notebook.
