| 387546 | 2005-09-10 03:21:00 | I've looking at buying a new computer and trying to decide on PC vs notebook . Can someone give me a guide to comparing PC CPU speed vs notebook CPU speed? It seems that most new PCs are 2 or 3GHz, yet notebooks are around 1 . 5GHz . Why such a difference? What would a 3GHz PC CPU compare with for a notebook? |

| 387547 | 2005-09-10 03:29:00 | Notebooks can get their power from a battery . The faster the CPU runs, the more power it uses, and the shorter the time until the battery is flat . Higher capacity batteries are heavier, and cost more . Notebooks are sold partly on their battery life time (long) and total weight (small) . |

Intel realised they didn't design the pIV too well, so they went back to the pIII design for the pentium m. Someone will correct me if I'm wrong, but I think that the pentium m has lower power consumption than an eqivilent performance AMD processor. | Greven (91) | ||

| 387550 | 2005-09-10 04:38:00 | As always, the major factor should be what you want or need to do . If you want to type letters, a processor which can wait at 4GHz for you to hit the next key is wasted . If you are doing this away from a power point, it's going to drain your battery faster, and that will be the only "benefit" of the higher speed . If it's a desktop, it doesn't matter . (A notebook will have power management, so the processor will be slowed right down when it isn't being used, so this is a little bit unfair, ;) ) . If you want to do lots of image processing or other heavy computing, a desktop is going to be better . If you have to have the portability, accept a slower speed, which won't actually be noticed in most work (it can still think faster than you can) for the sake of battery life (which you will notice) . There have been some "notebooks" been designed as "desktop laptops", which are sometimes even sold without batteries . They don't have power management, so are not very satisfactory if a battery is installed . |

| 387551 | 2005-09-10 05:15:00 | My parents recently bought me a new computer but i had t ostay under $800. I originally planned on getting a laptop but ended up getting a desktop because the performance was so much better on a desktop in my price range. | CorbinH (37) | ||
| 387552 | 2005-09-10 07:02:00 | my laptop is most definitly marketed as a desktop replacement, though it wasn't one of the nasty ones sold without a battery or power mangement, battery life was good for near 2 hours with all the software controlling the power use. Since then I have removed all the power managment, I pay for power then I want it on tap.Also the battery has died. Anyhow, its a 2800,512mb ram,9600pro, a smilar spec'd desktop would spank it sideways. As for the p4 not being a good design, thats only because the AMD is better,and the arcitecture of teh p3 was or is more suited for a laptop.the P-M is still easly destroyed by a p4 chip or an AMD Athlon, though not if you restricted the clockspeed of the desk top to match the laptop chip. The higher end P-M chips do the job perfectly for the average laptop, plenty of grunt. |

| 387553 | 2005-09-10 07:22:00 | Also as far as i know most of the lower end ($1000 down) either have no or a bad graphics card... and just of curiosity how good are intel Xeon processors cuz i have afriend whos dad has a computer with a 3.5ghz Xeon and like 3 gigs of ram... yet i dont know how fast it is and it bothers me lol | CorbinH (37) | ||
| 387554 | 2005-09-10 07:25:00 | generally you have to spend over 2G to get a laptop that has a game capable video chipset with its own video-ram. Though even then they lag well behind desktop performance, there are massivly powerful units available overseas that use the 6800 ultra, haven't seen them here though. |
