    What will Powermacs be like to differentiate themselves? After all it is unimaginable that a laptop is as powerful as a workstation (why buy a workstation then?!)

    Perhaps they will be quad across the board? :cool:

    You don't really think they will use the same processor? Apple may end up using a dual core processor in its mobile range, but that doesn't mean you wont see faster processors and more of them in the desktops. The PowerBook is still a portable and it has to suffer all of the limitations that come with batteries and battery life, unless you want them to build a PowerBook with a 10 minute Alienware battery life.

    Exactly, you may see dual cores, but the desktop dual cores will be even more powerful because you don't have to worry about heat and power usage as much.

    I think it may be reasonable to expect some applications to perform on the
    level of current dual processor desktops, so you will be able to do more
    work faster or at least more efficiently.

    Another difference is that these new processors will hopefully run much
    cooler using less power, so that will help with battery life.

    We might also see improvements in graphics if they develop better
    methods of increasing dedicated video RAM without adding excessive heat
    and power consumption.

    I'm also pretty sure that most laptops will use improved HD displays
    across the lineup.

    If previous speculation becomes reality, you may also see dual boot and
    triple capabilites allowing the user complete freedom of choice to run
    ANY application they need to get their work done.

    These improvements may not all come at once, but the next two years
    should be amazing.

    1 - Desktops are most of the time easier to upgrade
    2 - Desktops are cheaper than portables - if everything evened out, you'll still fork out more money for the portables
    3 - Portables' battery space restrictions make it hard to have new hardware - e.g. better video cards, better hard drives, etc.

    As for the video card thing - what they could do is maybe look back at an older technology with older video cards. They had the ..WRAM... WDRAM...???... see its old I don't even know what its called it was installable RAM on the video card. But put aluminum around the RAM with fans around it and a liquid panel that sits on top of the RAM. Overclock standard RAM such as DDR2 RAM to 733MHz, and have that be the main RAM for the VRAM. Setup a dual bus channel so that data rates are used to an optimum level, set the card up to where it accepts 3 different speeds of RAM, 533, 400, 333. Have it only upgradeable on one module. Setup another module that would flip the cache from the RAM module to built onboard RAM to increase speeds... Here's it more simply:

    Cool Video card sufficiently - liquid panels, fans, and aluminum casing
    Use DDR2 SDRAM as a VRAM RAM Module but overclock it (hence cooling)
    Setup at least 128MB cache to flip VRAM RAM Module (VRAMRM) to the standard build on VRAM.
    Use dual bus channels.
    Accept only certain speeds of RAM
    Could they do that?

    Desktops will always be ahead, if only for Intel and Apple to differentiate and not cannibalize sale.

    Desktops will always have the advantage of unlimited power and better cooling. Even as the new Intel CPU's get better performance per watt, you can still stick a more powerful CPU in a desktop.

    At some point you have to give up power for portability. The desktops will be evolving just as quick as the laptops, and because they are so much futher ahead, they will keep their lead, at least thats how I look at it.

    The main reason is power consumption. If we had an infinite power source, the next thing we'd be looking at is heat output. If we had both of those under control, Portables would be as powerful as desktops, but its power consumption that is holding portables back.

    No doubt there will be different processors for desktops and mobiles, but from the recent Anantech reviews the Yonah came REALLY close of the AMD64 X2 CPU running at the same clock speed.

    I really wonder what Intel will do for their desktop chips based on the Pentium M.

    Search Google for information on the Intel Woodcrest.

    Graphics cards, Hard Drives and ram will all be faster, better and larger than laptop ones.

    The main reason why I thought of asking is because suppose a Yonah PB comes in Jan, with dual core 2.0, wouldn't a similar speced PM suddenly look weak (especially if it is in the same price point too)?
