Don't be so quick to dismiss Celeron M vs Pentium M

Thread Starter 
I own a Acer TravelMate 4000
I recently purchased my sister a Aspire 1414

The system specs are as follows
Travelmate: Pentium M 1.4 GHZ[Dothan]2MBL2 (90nm)/512MB/60GB/
Aspire: Celeron M 1.4 GHZ[Dothan]1MBL2 (90nm)/512MB/40GB/

Tested on the newest version of Sandra
Focused on the CPU aspect
Scores on left are Pentium M, scores on right Celeron M

PENTIUM M CELERON M
CPU ARITH 5964[MIPS]2463[MFLOPS] 5581/2287
INTEGER/FPU 13318/14560 12243/13610
MEMORY BANDWIDTH 2048/2030 2218/2109

Wow not that big of a difference huh? Real world difference is very hard to tell as well. I know that the Celeron M is based off the Dothan architecture and has only 1mb L2 opposed to 2MB L2. The manafacturing process is both 90nm, the only thing absent is the speedstep which makes a considerable difference I can get about 4-5 hours easy. As opposed to her Celeron pulling in about 2 hours max granted the battery is smaller, it is very apparent how the battery life suffers without speedstep, running at a fixed voltage as opposed to multiple. All in all speed wise the L2 cache makes a very small difference, and the whole thing about Celerons are crap is completely garbage, these new Celeron M are VERY NICE processors that kick out decent battery life take a look guys.

I tried to explain that to someone awhile ago...you're completely right. The Celeron M runs pretty close in performance to the pentium (both M's of course). The Celeron basically just has the battery saving features diabled.

I basically agree with both of you.

Just to mention, however, Intel's site makes it look like 1.5 is the slowest Dothan (well, other than the low voltage variants). (http://www.intel.com/products/proces...iumm/index.htm). No chance that the 1.4 Pentium M is a Banias, is there ?

Exactly. The celeron M is a good performer.

usually the extra 1 MB cache makes about 100 mhz difference. So a celeron m at 1.4 dothan ghz should perform on par with a dothan clocked at 1.3 ghz.

Spiffy!

Does the Celeron M get hot running @ 100% all the time?

The Celeron-M has SpeedStep too. But the Dothan has a more advanced version of SpeedStep (I believe they call it ultra deep sleep mode which the Cel-M doesn't have.)

no, the celery has no speedstep, its disabled. IT runs at full speed all the time. THe dothan can run as low as 600 mhz.

Celeron M has SpeedStep: goes at min when on battery and on max when on AC - no dynamic frequency variation

Pentium M has EnhancedSpeedStep: dynamically change frequency between min and max at intermediate step.

I hate to bump a 3 month old thread, but what kind of difference in battery time are we looking at? Also, wouldn't a Celeron M with spare battery be cheaper and give more usage time than a Pentium M?

Thanks.
