    need help.

    Can anyone out there distinguish between the following terms.

    - Centrino
    - Celeron
    - Hyper Threading

    and which one is best amoung them as compared to price and functionality.

    Saeed.

    Centrino: Not a processor but a mobile wireless technology that is used with the Pentium M processor. - "Centrino (also called Centrino Mobile Technology) is a marketing initiative from Intel for a particular combination of CPU, mainboard chipset and wireless network interface in the design of a laptop personal computer. The combination currently consists of a Pentium M processor, the Mobile Intel 915 Express chipset family or the Intel 855 chipset family, and an Intel PRO/Wireless 2100 (IEEE 802.11b), PRO/Wireless 2200 (IEEE 802.11bg) or PRO/Wireless 2915 (IEEE 802.11abg) network connection. "

    Celeron: A low cost Intel Processor primarily designed and aimed at low power needing home/home office users. It's not as powerful or versatile as the Pentium 4.

    Hyper Threading: Hyper-Threading Technology (HTT) is Intel's trademark for their implementation of the simultaneous multithreading technology on the Pentium 4 microarchitecture. It is basically a more advanced form of Super-threading that first debuted on the Intel Xeon processors and was later added to Pentium 4 processors. The technology improves processor performance under certain workloads by providing useful work for execution units that would otherwise be idle, for example during a cache miss.

    --
    Depending on what you want to use your computer for depends on the processor you are gonna need to buy. A Celeron is fine for standard home computing however isn't exactly powerful for gaming. Centrino is on Laptops seeing as it is a wireless mobile technology.

    it seems centrino is much better than celeron for gaming and other development. I was planning to buy a laptop and was bit confused init. now what I had decided to buy a Toshiba Satellite M50-130 Notebook PC. Is it fine or shall i go for another one ? It will mainly use for gaming and Web Development.

    A Centrino (Pentium M) processor is better than a Celeron but it also costs more.

    I have never personally liked true gaming on a laptop... Cramped keyboard, limited memory, limitations with video and sound quality... Granted laptops have the potential to be built for gaming, however, in most cases it is far cheaper to buy a power hungry gaming desktop...

    The Pentium M processor is not a gaming processor... The Pentium M is built to optimize power consumption... Because of this, it is built lighter and without the standard shell that a Pentium 4... This means that the chip will run hotter so therefore needs to run at a slower processing speed to help lessen the amount of heat...

    For gaming, the Pentium 4 with HT is the best bet... But fewer and fewer manufacturers are using the Pentium 4 in their laptops... I know Dell, Sony and HP have models with the Pentium 4 but I don't know about any other manufacturers...

    I might have to disagree there because I have had a Tosh Sat A40 which had a celeron, I then changed to a Tosh Sat A50 with centrino and gaming got worse. Previously played games would only just about keep up on the A50. Graphics support is what I put the problem down to.

    Apart from the gaming, web developement is great on a laptop until you check the colour on a desktop. I developed a website with a lovely blue colour only to find out that it were purple on a standard monitor.

    What?? What video card did it have? I know the quality of some LCD screens isn't that high but any site I've developed on my laptop (which has an ATI 9600 64mb graphics card) have always looked the same and perfect on TFTs and CRTs alike.

    1) Most notebooks dont actually have a fan on the processor either. Hence why they developed the Pentium M (P4M) to run cooler. Prolonged periods of gaming would generate a fair bit of heat and ultimately that is not good for the machine.

    2) Most notebook hard drives only work at 5400RPM where as desktop hard drives (both IDE & SATA) run at 7200RPM. Thats a big difference when trying to get information from the hard drive.

    3) Most notebook graphics cards share the memory with the onboard memory. So if you see that it has a 128MB graphics card, that normally means that it is using 128MB of your onboard memory. They do make notebooks with dedicated memory graphic cards but generally not bigger than 64MB.

    I have both a notebook and desktop and I only use the desktop for my music (recording) and games. For basic web browsing, word processing I use the notebook.

    These are the spec's on my notebook and I can play games on it, but I get better performance from my desktop

    Tecra A3
    Intel® Pentium® M Processor 740 1.73GHz
    512MB RAM
    60GB 5400RPM Hard Drive

    My desktop specs;
    P4 Hyper Threading 2.66GHz
    1024MB RAM (DDR2)
    FX6600 256MB Graphics Card
    2 x 80GB 7200RPM SATA Drives

    The desktop cost considerably less than the notebook and well and truely out performs the notebook for gaming.

    Actually lots of them do, you can't typically have a modern processor run just on heatsinks with no way to really circulate the air.

    2) Most notebook hard drives only work at 5400RPM where as desktop hard drives (both IDE & SATA) run at 7200RPM. Thats a big difference when trying to get information from the hard drive.
    Actually the most common laptop hard drive speed is 4200RPM, but you can buy 5400RPM drives now days for them.

    I work in the corporate space and most notebooks have 5400RPM drives, maybe its different for the retail models of notebooks, but I very rarely see a notebook with 4200RPM drives.
