what is celeron M??

[Frightcrawler]

Okay, some people are confused here.
The Celeron-M in this discussion is the BANIAS/DOTHAN derived one. Depending on which one you get, it will have either 1mb cache or 512k (dothan and banias derived, respectively).
NOT the pentium-4 derived celeron MOBILE or the Celeron D! Understood? Good!

http://www.intel.com/products/.../processors/celeron_m/

Blame Intel for their crappy naming schemes.
I cannot find the article right now, but I remember that the banias Celeron-M performed relatively close to the banias Pentium-M. It just didn't have the power saving features.
So in conclusion, Yes, it's a good deal if you can take the name (Celeron ) and the non-throttling features.

I have a 9700 based centrino laptop and both a 1.5banias ans 1.3celeron I can run tests if you wish, but searcg for an article at lost circuits and iirc it showed both

Till celeron 340 it uses banias core ( 130mm ) with 512kb and...from 350 onwards its Dothan core (90mm) and 1mb l2 cache . Which means the new dothan based will have more or less the same performance of pentium mobile when used for day to day application...

So basically... a celeron M has the has cache and bus speed at the Pentium 4 (2.2, 2.4) etc...

I wonder how their performance compares.

Anyone know if the Celeron-M is pin compatible with the Pentium-Ms? I am considering building my own laptop, getting an ASUS notebook without the CPU. If the notebook is listed as "Pentium-M", can I use the Celeron-M instead?

Probably depends on the BIOS more than anything else. In the Dell machines, it looks as if the Celeron M and the Pentium M are interchangeable in their configuration setups, so I would guess that they are pin compatible.

if getting celeron M before jan 2005 , chances are you might be getting it with Banias core.....except few models ... from Q1 2005 intel will ship most of celeron M with Dothan core only

Overclocking and 1.3ghz dothan vs banias vs celeron-m (512) interestingly the celeron M required just 1.31v to reach 2.0ghz vs 1.46 for banias. Think ill keep my celeron M and wait for the promised desktops

I?ve just compared two Acer 292s over the last 3 days; one P-M 1.5 Banias and the other a Celeron-M 1.3.

I installed a third party utility on the P-M, which allows you to set the speedstep features independently for battery & AC usage. It means that speedstep can be set to Minimum performance, Maximum performance or Dynamic mode. I set it to dynamic mode for both AC and DC and it ran very coolly and quietly.

Dynamic mode is a more sophisticated implementation of what AMD have with Cool ?n Quiet. It supports up to 5 or 6 power states versus AMDs 2 to 3.
In comparison the Celeron-M was noticeably warmer and noisier, even under a moderate load. Celeron M based laptops sometimes use the cut down chipset also, which only support lower frequency RAM. That?s important as a Celeron M machine is very likely to use integrated graphics.

I think it was tomshardware that did a benchmark comparison that showed how little difference there is between a Celeron M with 512 kb and a Pentium M with 1024 kb. This was in most cases, although no doubt some specialist apps such as scientific stuff might show a bigger margin. Unsurprisingly, the gap between Dothan and Banias is also unspectacular. I guess you can compare it to the Athlon 64. The performance gain there when jumping from 512 to 1024 hardly seems to warrant AMD moving up to 2 Mb, at least on the desktop.

In terms of battery life, the benchmark showed that a Pentium M system that gave 4.5 hours of usage would give about an hour less with a Celeron M.

I don?t remember the name of the utility but it was very useful and is freeware. It?s for XP only, as I think Intel make a similar utility for Windows 2000 that also supports the P3-M.

Which software did you use?

Besides speedstep feature and battery life ..How does the celeron M 1.3 stand with P-M1.5 .
Did the 200Mhz diff and the low cache memory of celeron showed significant drop in performace ??
