Advantages/Disadvantages of Mobile Processors compared to Normal Processors
Hi,
I am looking at purchasing a laptop in the near future. However looking at Dell there appears to be two different types of processors, a "Mobile Intel Pentium 4 Processor - M with Speedstep" and just an ordinary "Mobile Intel Pentium Processor". For example, with the Inspiron 8500 and 5150. The "-M" processors seem to be both more expensive and slower than the ordinary ones. So what are the advantages/disadvantages of these processors? Why would I want to buy one instead of the normal processors? Any advice/information would be much appreciated. Luke |

The Centrino processors are the ones with wireless capabilities built into the actual processor arn't they? Just quickly, you said if it is between 1.3G and 1.6G then it is probably a Centrino, but with the Dell ones (eg: http://www.ap.dell.com/ap/au/en/gen/...al_offer_2.htm) they appear to have much higher clock speeds (eg: 2.5ghz). So I take it these arn't actually Centrino chips? (Maybe I should email Dell) Thanks for the help Luke |

The Centrino processors are the ones with wireless capabilities built into the actual processor arn't they? The full Centrino package is CPU, Chipset and wireless ethernet. However some companies are just using the CPU and chipset and leaving out the wireless.

So I take it these arn't actually Centrino chips? (Maybe I should email Dell) It seems that niether of these are Centrino units, sorry, my mistake. If I were in the market for a laptop I'd go with a Centrino-based unit. They are far superior to lappies based on desktop CPUs (albeit modified for mobile use). The -M designation seems to be for CPUs that run cooler/lower voltage and change their speed in Mhz depending on whether they are running on mains-power or battery power. They are nowhere as efficient or powerful as the Centrino CPUs however. The Centrino CPU is the first CPU built from the ground-up for mobile use rather than a desktop CPU ported over for mobile use. If you google alt.sci.seti for centrino you'll see that these CPUs are *very* fast compared with the desktop/mobile hybrid we are used to seeing in laptops and do it on half (or less) the power. -- ~misfit~ --- Outgoing mail is certified Virus Free.

If you want a low priced notebook with a mobile processor, you should
be looking at notebooks with a mobile Athlon XP processor. Luke wrote: Hi, I am looking at purchasing a laptop in the near future.

Or an empty pizzabox... it would work just as well. I am looking at purchasing a laptop in the near future.
