Celeron - how much more heat/noise?

Hi all, I'm seriously considering getting a laptop with a Celeron chip (please withhold your gasps of horror) and the only thing that I'm concerned about is the lack of speedstep. I am interested to know how much of a difference this will make to heat and noise output.

The alternative is a Pentium dual-core in the same chassis (Compaq C700 series, C731TU and C742TU for those who are interested).

An additional but lesser concern is power usage, so any comments on that would be welcome.

 

Well I've got a Celeron M 540 in my laptop and it's excellent. Doesn't produce much heat and is very quiet! Mine is a 65nm and is the latest model and revision.

 

The pentium d's have terrible heat that is almost similar to the p4 man...stay away from those suckers...

 

He's not talking about Pentium D, he's talking about the mobile cpu (celeron m) which is a far far far cry from the netburst architecture of the PD. It is based on the merom core...

 

Pentium Dual-core is different from Pentium D.

 

Yeah he's asking about a Celeron M not any Pentium. Would help if you actually read the original post.

 

I think he got mixed up, the OP was talking about Pentium Dual Core which is based on the Core Duo and Core 2 Duo chips.

I have a Celeron-M 380 (Pentium-M generation). It idles around 48-54 C and gets to 65-69 under load, which is actualyl better temps than my partner's Core Duo.

It's fine for power in XP and capable of a good amount of multi-tasking (yes people, single core can run more than one application... ).

My battery is a awful 4-cell but as my laptop stays plugged in 98% of the time this doesn't concern me. You will get less battery life with a Celeron-M but I wouldn't say it was drastically less at all, maybe 10-20% tops.

I'd say if you want a Celeron-M based laptop don't be worried about getting it, if you know what that entails against other cpus and you're ok with it, go for it. I am very pelased with my Celeron-M laptop, it's the only pc that I've owned within the last few years (and that's a lot) that I've kept for more than a few months. 18 months now and I have no plans to upgrade to a new laptop or sell it etc.

 

Well im also woundering how much diffrens would be in gaming. My friend is thinking of buying a zepto with 8600gt ddr2 card and cant decide if it would be ok to go with celeron 1,8Ghz 1mb cash or 1.66Ghz C2D with 2mb cash. The cost diffrens is about 100 dollors. Woundering if it is worth it if the battery is not a issue for him(it would be a light LAN pc)

 

If he wants to game or do 3D/video work then the C2D is a must. If not then the Celeron M would be fine.

 

Im not sure, but i would think that a Celeron would have less heat and noise output. I know that my Celeron is alot quieter than my friends (he has a regular P4). His is very loud. I barely hear mine and it is the same case and model.

 

I suppose it depends what games. If he plays supreme commander then the C2D would be preferable. Also if he intends to play the very latest stuff. If it's not the newest the Celeron-M should be fine. I only noticed a small improvement moving from a Sempron to an Athlon X2 in my desktop, it's more about ram and graphics card these days.

$100 difference... that's tricky. I suppose personally it would come down to whether I wanted to use it on battery a lot. If he's on a tight budget and woul prefer not to spend the extra the Celeron-M will do the job well, but if he can afford the £50 without worrying I think the C2D would be the better choice overall.

 

This I find interesting - I was wondering if running at full clock speed all of the time (as a result of no speedstep) was basically the same as running at full load all of the time. Apparently it's not...in that case I don't quite understand how to estimate heat production, it seems to be a combination of load, clock speed, and very probably other factors.

Essentially, probably too complex to estimate.

But in essence, I guess that the main issue is this: the computer will be running at a low load most of the time (just office tasks and web browsing). Therefore can I expect that heat, noise, and power consumption will be not very much higher (no higher at all would be ideal) than for a CPU that has speedstep?

I guess that noise is my primary concern...I'd very much prefer to have the fan running as little as possible.

I will be running Vista, also. I'm 99% sure that performance should be fine with that OS and those tasks, but if someone could confirm that I'd be very appreciative.

 

I have Vista Home Premium and it runs great

 

How much RAM are you running it on, by the way?

 

I had a 1.6ghz Celeron M in my Acer laptop and yes, it did run very hot.

I regret the day I bought a laptop with a Celeron in it. I thought they would be better "these days" - do NOT pull the wool over your eyes!! My Celeron 520 would run around 145F, whereas the core 2 duo T5300 I replaced my Celeron M with doesnt go above 110-115F most of the time...

My advice: buy the laptop you want with the Celeron (cheap), my Acer 3680 was $349 at Micro Center... Then go buy a Core 2 Duo and upgrade (~$75 or so on Ebay). Its the best upgrade I have ever done on ANY of my computers.

 

michacerboy - Can you find me a Core 2 Duo for that price in the UK?
