Which is better - 64 MB Shared Video Memory, or 32 MB Dedicated? (for Tablet PC)

My boss is considering purchasing a convertible tablet pc.  He'll use it 1/2 for hand-writing and drawing and 1/2 for typing.  He also wants to be able to play a new golf game while he's waiting in airports, etc.

I think I've narrowed the search to the Acer C303XMi-SP2 (1.7 GHz, 1 GB, 14.1" TFT Active Matrix, 64 MB Shared) versus the Toshiba Portege M200 (1.7 GHz, 1 GB, 12.1" SXGA, 32 MB GeForce FX Go5200).

So, which PC is going to handle his golf game?

    Hi DaninWV,
    Shared is always worse than  dedicated.

    So, even though the shared memory is 64 MB and the dedicated is 32 MB, the video will be better with dedicated?

    Not necessarily. But often, dedicated video memory runs faster than main memory, and both can be used at the same time, so you CAN get some better performance.

    Also, with shared video memory, it's often done to save money and reduce component count. This means that you are probably not interested in performance.

    However, with shared memory, if you are doing nothing too graphics-intensive, you can reduce the amount of memory used for video and free the rest for use by your program of choice.

    Help us out and let us know the title and version of the golf game.

    Now as for your two machines, the Acer uses Intel Extreme Graphics 2, built into the PCI chipset. It's an OK controller, definitely NOT meant for gaming, but may do a fine job on the golf software.

    The GeForce in the Toshiba will BLOW AWAY the Intel graphics in anything intensive like Doom 3 or Half-Life 2.

    The golf game may or may not take advantage of that extra ability.

    I think other factors should come into play here:
    - Will other games eventually be used on the machine, maybe by someone else? Or maybe the golf version that comes out next year will need the extra performance...
    - Do size and weight matter? Travelling a lot?
    - What local support options are there?
    - How long will the machine be used before being taken out of service, and to whom will it be sold?
