My notebook search is getting more desperate....HELP

post #1 of 5
Thread Starter 
I have been lurking around here for a while, researching and trying to find the right notebook to me, but I'm really conflicted. Can you please help me decide?

My basic situation: I need a laptop for everyday use sitting on my desk, and possible occasional mobile use (taking it to the library for research or for working on a group project). I will be doing lots of graphics and 3d rendering. Not so much gaming. And also writing papers, email, and other college student type stuff all the time.

I was all set to get an acer travelmate 8000 - perfect mix of speed, large screen, good graphics card, and portability. But then I looked into Dothan a little more and found that it really falls behind pentium 4's in terms of graphics-intensive processor activity. This put me back at square one.

Then I was thinking about getting a p4 notebook. But then my logic goes: Well, I can't get a p4 with a big screen that's light enough to be really portable, so i might as well go nuts and get a lot of bang for my buck. So then I was enamoured with the acer aspire 1712. But then I went, "hang on. do I really want a 14 pound laptop!?" And then I was back at square one.

I will most likely be selling whatever I get about a year from now when i move back to japan and will need a superportable, so I can't see spending more than $2k on this one now, if that. But I really need a good computer for the projects I'll be working on at school. I've looked at the HPzd7000 and some sagers, but it always comes down to "If I'm going to get an 11 pound monster, why not get a 14 pound acer and get more computer and an even bigger screen??" I guess whenever I get excited about a big computer, I flash forward to the one day I need to haul it all over campus and I'm cursing my stupidity and naive processor speed greed. But i really dont see myself carrying around very much at all.

So what do you all think? Will the shortfalls of a pentium M come back to haunt me? Or is the light weight and long battery life worth letting things render during the night instead of during dinner? Are there other machines I maybe have missed considering, something like the travelmate 8000 series, but with a p4? Am I so wrong to be thinking that if I'm going to be looking at 11 pounds, it makes sense to make the jump to 14? Also, how about the 64 bit AMD in the new ferrari? I've heard a lot of mixed messages.

Thanks so much. I've been asking people i know these questions, but I want the opinions of the knowledgable people i always see posting here.

No, Pentium M and especially the new Dothan chips are real performers, id go with the CL56, according to the 1.5 rule, a 1.7 Pentium M is equal to a 2.55 Pentium 4 and a 2.0 Dothan is equal to a 3.6, , you wont otice much peformance decrease at all

That's why Pentium-M processors have model numbers now instead of using just Ghz. Also, the technology in Pentium-M processors will be used in the future desktop processors from Intel.

how much 3d modeling are u going to be doing? if that's what you're mainly going to be doing, P4 is probably the way to go. the higher clock will really help you there. alternatively, the P-M architecture does a pretty good job of keeping up in Photoshop tests (large cache). if you're going to be doing more graphic design, you might be able to stick with a P-M. Pshop/Maya benches:

in scientific apps, the P-M gets outclassed by the P4s / a64s. if you mainly use programs like mathcad/matlab or other progs that do a lot of floating-point calculations, grab a P4.

while the P-M gets much more out of every clock cycle, making it nearly comparable to P4 in certain aspects, 1 Ghz or more is a pretty big differential to make up for, and it falls behind in several areas that might be important to you.

"What’s interesting to note here is that the Pentium-M (Dothan) and Athlon64/DTR models appear to scale almost identically in terms of clock speed, while the standard Pentium 4 appears to be criminally inefficient on a clock for clock basis, but makes up for this with a ~1 GHz clock speed advantage over competing chips."
(a64s 3400+ is clocked at 2.2 ghz)

since you said you would be doing a lot of "graphics and 3d rendering," and your "computer will mostly sit on your desk," i would say go for a high-end P4 system. you can actually find them relatively portable in many configs, < 8 lbs might be fine for occasionally toting to the library for a group project.

naturally if you feel that the performance differential won't hold you back from what you need to do, the P-M low-power benefits are really nice. good luck with it

With a 2mb cache, you can cram all the rendering routines plus all the vertex buffers right next to the processor. Rendering speed will be far from compromised.

And unless you are doing time-critical work (must be rendered by 5pm today!) you probably won't need that much power. That situation will never ever happen if you plan ahead, anyway.

And like you've lamented, P4 notebooks are BULKY.

The centrino family processors are much more versatile than the P4 in terms of general use.
