    hey i own a notebook and a desktop PC.

    my own desktop PC specs:

    1 GB DDR400 SDRAM
    128 MB geforce 6800 xt tdh agp bus graphics card
    intel p4 2.8 GHz 512 MB l2 cache 533 FSB CPU
    THermaltake matrix 430 watt chassis


    i installed fifa 09 demo.graphics are nice but game is a bit slow.even i defragmented)

    and notebook:

    2 GB DDR2 667 MHz SDRAM
    128 MB crap ATI RADEON X1200
    amd athlon x2 dual-core 1.9 GHz CPU


    then installed the same game for the notebook , game fluidity was a liitle bit better but graphics were
    ugly thats why using a bad graphics card

    let's come to questions

    question 1: fluidity in the gamespeed is sourced by CPU difference only?

    question 2: during a game is running, the biggest workload is done by graphic card? how effective
    is the memory(RAM) at that time?

    question 3: as you can see,graphics card on my notebook is worser than my desktop PC
    but CPU and the RAM is better.that's why gamespeed is better on my notebook.
    if so, what is the importance of the graphics card at that time about "performance" ?

    question 4: after the CPU has made his job to process, when does data go to system memory?
    when to graphics memory?

    Note: please write your answers in order.. like answer 1 answer 2 and so on...

    Naaa, your alright!!! Sounds too much like homework. :biggrin

    Seriously though, if you have one bottleneck in your PC it will deteriorate the whole performance of the game.

    No point in getting a top of the range graphics card if you only have 64MB RAM. 8)

    Hi Kobem,

    From my understanding the RAM holds most of the information about the game from when you load it up. Example: If you play an FPS game, the CPU will load all the information about the map and store it on the RAM for quick access later. So say you have less RAM or a slower CPU, you might not be able to cache the entire map, or access/deliver data to GPU quick enough and as a result will experience some slow down when moving to certain areas.

    The CPU will be updating the GPU whenever you make changes and then adding them to the RAM for access later. Example: You move to another area of the map but you don't shoot or pickup anything, no change to the RAM is needed but the CPU needs to tell the GPU to render your new location. Say you shoot a wall and pickup a few items and then move on: Your CPU will process the information and update the GPU as much as it can then it will store the map layout/information change on the ram.

    As for video output the main job for the graphics card is to produce the rendering of textures etc and this is why you've found the display to be worse while the speed is better on the laptop.

    I'm open to correction but this is how I put it together :D

    DirectX version can also make a difference.

    Call of Duty 2 runs better in DirectX 7 "mode"

    Lemme get this straight - you've got a desktop AND a notebook, but can't afford a lousy 15 quid for a book on network+?

    1. If you have a crap graphics card the graphics will be crap.
    2. If you have a slow CPU the computer will be slow
    3. if you have a low amount of RAM then the computer will not be able to process lots of instructions.

    what DaveMid says is right :)

    i am sorry your explanations are very good..

    two additional questions

    1. forget the game, think same questions(above) for photoshop , gimp graphical applications
    2. for normal time.. just normal programs such as excel,word

    The same rules apply for both Kobem. The CPU takes the application data from the HDD, sends it to the RAM for quicker access and the GPU displays the application/images etc. You start making changes and the CPU makes the changes happen by taking and giving information to and from the RAM and then to the GPU to update your monitor.

    Hope this helps.

    ...or the A+ book, considering benchmarking of PC components is covered there. :popcorn

    I was going to suggest A+ as well, as it does cover this process quite in depth - compared to my summary.


    ..

    But then I forgot by the time I logged back in :D

    If it is home work,why dont you post what you think the answers are and get replys to those.
    but what Sparky has posted basically covers it.:p
