centrino/amd 64 heat

HI all,

I'd like to know witch one between thoses two CPU heats the more? A AMD 64 bits Athlon mobile(low voltage) or a dothan 1,7 GHz centrino?

Also, do you know a site where there is a comparaison between a P-M and an AMD cpu temperature?

Thanks,
Blacko

I went to Best Buy to figure this out. The laptops there run for hours on end so about 6 in the evening you can answer your question firsthand. Be aware that it's not specific to just the selected CPU. The laptop make/model (design) can make either a winner or loser in this comparison.

Pentium M (Centrino), Apple cpus (made by Motorola, etc) and Athlon 64 cpus all run at drastically lower mhz and thus generate less heat than Pentium 4M's.

The Pentium 4M chips are at or above 3mhz but the Pentium M (Centrinos) are at 2.0 mhz or lower and the Athlon 64's are also in the 2mhz range or lower depending on chip speed.

You can tell which cpu is the most energy efficient (longer battery life and less heat means thinner notebook cases) by looking at the notebook thickness and weight.

The Pentium M (Centrino) has the least heat and longest battery life on the PC side. Apple is excellent also in its own realm.

A Pentium M Centrino notebook gets 3.5-5 hours or more battery life in some cases (depending on whether wi-fi is turned on or not, etc) while the Athlon 64 notebooks get higher battery life then Pentium 4M's but less than Pentium M's (2.5- 3 hours I think but not exactly sure).

At any rate, you can easily compare Athlon 64 notebooks to Pentium M notebooks with the same LCD size and see that the Pentium M's are thinner and lighter than the Athlon 64's (see hpshopping.com for example).

For example the HPZT3000 15.4" Centrino is 6.5 pounds -- I believe the HP and Compaq Athlon 64's (same LCD size) are about 7.8 pounds and they are thicker (as more space to cool the notebook is required).

Both notebooks are excellent -- the Athlon 64 has the future benefit of 64bit but the Pentium M gives the best performance/battery life/weight ratio currently with 32bit.

The HPZT3000/Compaq X1000 series fan does not even run at all when using wi-fi or Microsoft office etc (only comes on at startup, when using DVD or CD burner or using hard drive extensively (games). Thus, it so efficient the fan is not even on and the notebook is silent much of the time.

There are thin and light Athlon 64 notebooks in the works using AMD's new 25 watt mobile Athlon 64 chips. Expect to see them before the end of the year.

You can read the comparison between a Pentium 4M and Pentium M (Centrino) at the Intel website as they sell both cpus and want you to buy one or the other.

If you go to the AMD website (Advanced Micro Devices) they should have a lot of information on that cpu.

But, no, I don't think you are going to find a lot of comparison between the Pentium M Centrino and the AMD64.

Rather, the AMD64 gives an equivalent mhz speed rating to the Pentium 4M and the Pentium M is 1.5x-2x as fast as a Pentium 4M when comparing mhz.

If having your notebook run its best when 64bit applications appear (some out already) is paramount get an Athlon 64 (HP/Compaq or E-machines only currently among mainstream manufacturers).

If you want the thinnest and lightest notebooks with the best battery life available with an IBM PC notebook get a Pentium M (Centrino). Apple notebooks have some of the same benefits as Pentium M Centrino.
