Heat comparison between mobile XP and unlocked XP?

[MIDIman]

Hi all,

I currently have an unlocked 2400+ Athlon that I bought from here, and although its fun to mess with, its not really suiting my current needs. Mainly, it produces too much heat. I think the max I hit was 13x166, but I'm limited by PC2700 ram - what is that, like an XP2700+'s speeds?

I'm thinking about moving to an overclocked Athlon XP 45w Mobile, probably the 2500+ and then selling my current CPU. Been trying to find decent reviews and I stumbled on this one. It seems that a 45w Mobile XP overclocked to 2.4g performs close to a 3200+ Barton. Does that performance rating sound about right?


I suppose I'm firstly curious how much heat the 45w chips produces, while overclocked - for instance, at 2.4ghz like they have in the above review - in comparison with a similarly unlocked overclocked chip, and then secondly, if I'll get a performance loss. I'm assuming considerably less, but I'm just curious what people's experiences are with these.

edit - Just found this CPU heat reference on silentpcreview.com. I didn't know it, but the old 1700+-1900+ T-breds were actually around 45w-48w. Crazy ain't it?

If Tech Report had included the OC 2400+ you have it prolly would be competitive albeit on the bottom score with those other CPU's and the Heat on the OC 2500 Mobile would still see the high 40C's and possibly the lower 50's so I would save the cash and look towards a better upgrade because of your RAM unless you can do it for under $20....and 13X166 does equal XP27-2800 speeds with the T-Bred

The performance rating of the OC'ed 2500 mobile wouldn't be 3200+ it will greatly out do it... I have seen a review (can't remember where now of course) that showed a Barton Mobile 2500 (Oc'ed to about 2.4 or 2.5) beating the pants off a stock 3200.... it even came achingly close to some of the higher A64 chips.... so it is a fantastic chip all around....

Well TheStu - you have a 2500 mobile @2.4 with a 947u HS in your sig...what's your temp approximately at idle and load? What fans are you using as well?

Ironically enough, my plan was to move my SLK-947u to my AMD system and buy an XP-120 for the P4 system.

Absolute full Load is around 45-47C (Folding@Home, Prime, and Gaming) bear in mind though that that is at 1.781 VCore Not entirely sure wht my idle temps are since I almost never run idle.... but I would expect 38C or so....

I have a single coolermaster 80mm on the Sink, 2 80mm Aerocools exhaust in the back, 1 aerocool 80mm blowhole, 1 aerocool 80mm side fan and 1 80mm intake.... all inall my system temps are pretty low and the noise level isn't ridiculous

As a comparison point... my computer with as few progs running as possible will do 2 million decimal places in Super Pi in 99 secs at my current settings.... My friend with his A64 2GHz (i think 3000+ or 3200+) with 1 gig OCZ uber low latency rev.2 shizzle at 200 MHz will do 2 million in about 108 seconds... and at 215 MHz (his boards limit) he can do it in 93 I believe... so the Mobile can be competitive with any Barton and some of the A64s as well (just not so much in gaming)
