Comparing Laptop CPU performance

[cotswoldcs]

I am a little confused about CPU performance in Latops with such a large and varied choice. Can anyone help clear up the matter.

How does a Centrino 1.6Ghz for example compare to a Destkop P4 or AMD? Does anyone have a link to a comparison chart or labs test????

Thanks in advance

a 1.6 dothan should give equivalent performance to a 3.2Ghz pentium 4, or 3200+ Athlon64, in tasks like gaming

give or take, of course

the rock laptop has a desktop 3.2ghz p4 in it, the voodoo has an a64-3200+.

Thanks guys but let me be a bit more specific. My budget for a laptop won't stretch much more over £500 and I've been looking at an Acer TravelMate 4021LMi (link below)



This has a 1.6Ghz Intel Centrino 725 CPU


How does this compare to a desktop PC?

For a few pounds less (£4.00) I get a Celeron-M 1.5Ghz which seems a lot worse, although I'm only guessing ??

For a little more (£16 +VAT) I can get a Acer TravelMate 4401LCi AMD Turion 64 ML28 1.6GHz which has the AMD Turion 1.6Ghz CPU. How does this compare to the Centrino?


How do these latops models compare to say a Desktop P4 3.00Ghz???

Thanks

the turion and dothan are both faster than a 3.0ghz p4 - the celeron is slower.

and the turio might be slightly faster than the dothan, but have considerably worse battery life (and possibly a dodgy ati or ali chipset instead of nice stable intel)

just wondering how does a 2.8ghz Celeron compare with a P4 3.80ghz -
is there a difference in speed or do they remain the same?

depends on the task. on something with highly prtedictable, long pipelines with little cache issues (i.e. xvid encoding, mp3 encoding), then they're about the same. on anything slightly less predictable, cache-hungry p4 celerons fall off in a big way

Quite reasonably, except that the onboard graphics are going to be pretty hopeless at 3D (and you only get 256MB ram, 60GB HD etc.). The Pentium M is, for many applications, the fastest X86 processor around for a given clockspeed.

For a few pounds less (£4.00) I get a Celeron-M 1.5Ghz which seems a lot worse, although I'm only guessing ??

Yeah, slower, less cache, definately not worth saving £4 in this instance.

For a little more (£16 +VAT) I can get a Acer TravelMate 4401LCi AMD Turion 64 ML28 1.6GHz which has the AMD Turion 1.6Ghz CPU. How does this compare to the Centrino?

Well the spec isn't as good, smaller HD, no DVD burner. However, it has an ATi chipset- and the onboard graphics on that, while still hardly a powerhouse, are at least capable of some low res 3d gaming. Otherwise, the processor will be a similar to the Pentium M 725 for most things, maybe a smidge slower overall but not so you'd really notice. However it is a 64-bit chip, and so offers a bit more futureproofing. Finally, it seems that this lappy comes with XP Pro, I don't know if you might need the extra features.

Edit: oh, and the battery life probably won't be as good has directhex says.

For purely processor intensive tasks they'll be fairly similar. As for the rest of it- that depends entirely on how the desktop machine is kitted out with graphics card, memory etc.

The celeron is a lot slower in everything. Think about it, they have similar cores but the P4 is 1GHz faster than the celeron you mentioned.

Whats Dothan and Turian?

I have a 1.6Ghz Pentium M

[Ramedge]

i just wondered because its a celeron for a lappy ithought it may have advantages over a standard celeron (in a pc) or P4

Total objection to that. Got an Acer 5024wlmi, turion 1.8ghz, battery life with light usage is easily in excess of 3 3/4hrs with wireless on and used throughout! With 1GB of RAM + X700 in there too.

And as for crappy chipsets have you used the Ati xpress 200? Its an incredibly rock stable chipset platform. Not only that but modern athlon64 mobo's use them too, and no real reported major issues. The laptop has never ever crashed, and it gets a good usage too.

Get your facts right next time!!!!

Im just not happy with people slating products they clearly havent even tried thats all

[directhex]

i'm a linux user. i like a chipset not to run the system clock at double speed.

my centrino is *great* under linux, everything bar the modem works out of the box with ubuntu 5.04 or higher (and for the modem, i download and run one script from linuxant.com)
