| why are these moble m cpu's more money than normal cpu's on a laptop? i went to compusa today and this guy told me that the 1.5m is better than the 3.06 800 fsb. the clock speed is 10 times slower, and i bet the laptop is gonna be slow as heck, how go 1.5 rather then 3.06? i dont care about battery life and heating. i just dont understand laptop's can someone tell me about it? |

| uhm..do you understand the relationship between clockspeed and FSB? |

| he apparently doesnt understand that clock rate doesnt mean everything in cpus. Speeder u know that amds are only around 2.2 ghz but can be just as fast or faster than p4s |

1) dont listen to computer sales reps.
2) FSB (front side bus) x multiplier = clock speed.
the FSB is the link between ur CPU and basically the rest of the system. the higher this is, the faster the rest of the system opperates. imagine the FSB as a highway, the larger the number, the wider it is, and therefore the more information it can get down it.
clock speed isnt the ultimate measurement of how fast a CPU is. because of the above equation, there are several ways of getting 3ghz clock speed.
(they dont actually make CPUs with the below numbers, but its just to explain)
300mhz x 10 = 3000mhz = 3ghz. (FSB x multiplier = mhz (1000mhz = 1ghz)
or
250mhz x 12 = 3000mhz = 3ghz
or
100mhz x 30 = 3000mhz = 3ghz
so whilst all 3 of these CPU's are all clocked at 3ghz, the top one would be the faster system as its FSB is the widest, (the higher number). in choosing a CPU, the higher the FSB and lower the multiplier the better. if u want more detail i can link u to some good information sources. |

the processor in the laptop is probably pentium M, and yes they are quit e powerful
i say go for it, cause pentium 4 in a laptop just plain sucks
get laptops with pentium-m processor (centrino) because:
longer battery life
low wattage = less heat
better preformers than pentium 4 in the laptop environment |

the reason the P4 isnt very good in laptops is because the P4 is a performance chip. if u are going to build a new intel based system, then you'd choose the P4 over the M because there is no worry over power. most people use laptops for business use, word processing and what-not. the M is more than capable of business related things, whilst using half the power of the P4, and giving off half the heat.
so the chips are taylored to their environment. P4 for performance (games, video editing), the M for business style laptop use. |

I have a P4 in my laptop... ....
:disbelief
And it's a beast. Eats through the battery like a monster, I can get about 1 hour 40 minutes out of it, doing moderate activity like watching a video.
You should see the power brick also, it's huge. But I can also run games so beautifully, better than my desktop. And Reason, and photoshop, combustion, 3DSmax, anything I throw at it. so I say P4 is ok in a laptop!! |

P4 is good in a laptop if ur going to use ur laptop for performance applications like u mentioned above, and u can plug ur laptop into the electricity supply everytime you use it. if u want a low power consumption chip for long battery life doing low power tasks such as word, then the M is better. |

i have an M in the pc im on right now for school, pretty zippy with 512 of ram, i run games, reason, photoshop all with no problems... and its tablet style, which is kinda cool...
now i just need a proper external sound card |

The M variants are designed differently.
The reason AMD chips can perform as fast as P4's that are 800mhz faster in clockspeed terms is due to them doing more clocks per cycle, kinda like doing something slower but more often in the same time frame.
The M's are designed similary, so the Ghz doesnt have a true baring on the real use speed :)
Plus they chow less battery and make less heat which is always ideal, especially for laptops |

| you guys know too much about computers. all i know is that my 2 year old dell laptop runs counter-strike: source and looks up teh pr0n very well. that's all i need it for. |

| dude get a dell/toshiba with pentium-m or centrino with a 6800 go, its better, more customizable, and cheaper than most retail stores laptop. it will also play most of the games outthere and back |
