Pentium-M Banias or Dothan?

[rowen]

Hi All,
I tried a bit of a quick search on the forums here but didn't come up with too much. Sorry if this has already been visited 50,000 times

What are the differences (performance wise) between a Pentium-M banias and a Pentium-M dothan? I'm looking into purchasing a new notebook for work and the model I am looking at has a few options available. (The prices listed are the price to upgrade from standard, not the purchase price of the cpu.)

Options are:
Banias 1.5 Celeron-M 512K $0
Dothan 1.5 Pentium-M 2Mb $194.70
Banias 1.6 Pentium-M (Dothan 2Mb) $194.70 <- This is the weird one, i thought it was Banias or Dothan, not sure what they mean here?
Banias 1.7 Pentium-M 2Mb $250.80
Dothan 1.8 Pentium-M 2Mb $354.20
Dothan 2.0 Pentium-M 2Mb $552.20

I'm a bit lost as to the differences between the dothan or banias, originally I thought it was the onboard cache, but they list some dothan and banias, both with 2mb (is this incorrect)?

Which would be the best $/performance/value choice out of those listed cpu's?

What are the differences (performance wise) between a P4-M banias and a P4-M dothan? I'm looking into purchasing a new notebook for work and the model I am looking at has a few options available. (The prices listed are the price to upgrade from standard, not the purchase price of the cpu.)

Options are:
Banias 1.5 Celeron-M 512K $0

Dothan is 90nm, Banias is 130nm (Dothan will be cooler and will draw less power)
Enhanced Register Access Manager
Enhanced Data Pre-fetcher
Dothan is 2MB cache, Banias is 1MB
Dothan can achieve clock speeds higher than that of the Banias (I think 1.7GHz is it's highest)

That's pretty much it. I got this info from: http://www.hardwarezone.com/articles...cid=14&id=1106

As for the product choice, go for whatever you can afford. The best value one to me looks like the 1.8GHz (Dothan) which would perform similar to a P4 3GHz CPU. Seems like the pricing table is a bit dodgey...

A 2GHz (Dothan) would perform similar to a P4 3.4GHz CPU. A 1.5GHz (Dothan) would perform somewhere around the P4 2.4GHz mark.

edit: and just so you know, P4-M and P-M are different types of CPUs.

Excellent, that cleared a lot of stuff up.

So basically the Dothan is the preferred choice (in any flavour) and stay away from the banias as that is older tech?

With this in mind, I think the 1.8 will be the best bet as the 2.0 seems a bit rich in the $ field.

Thanks for your help.

Your using this in a laptop right?

Yeah go for the Dothan. The only real reason to go for older tech is if you don't have enough cash for the new tech. You'll probably have some regrets in the long run if you opt for the old stuff now to save a little bit of money

yes opt for the dothan as its a slight increase but an increase nonetheless from the banias..i unfortunately purchased a laptop with a banias a year ago before the dothans came out..but my laptop is upgradable to a dothan cpu...i may have to upgrade in the near future

oh and keep in mind these cpus are Pentium-M not Pentium4-M

Yes, I'm looking at a laptop from www.itchannel.net.au. The lappy is the millenium 6200 i think (the really thin one with radeon 9700 pro graphics).
