    Hello?

    Is the iPad 2 ram important? If the processor is improved and graphics are 9x fast, why is the ram important whether it's still the same or improved? If it's improved, how will it help?

    Thanks!

    If you're a spec hound, I guess it could be important. If you are just interested in how the device performs, it's not important. iPad 1 had 256 mb of ram and it performs great. iPad 2 has double the ram, plus a dual core processor, so it'll be even smoother. But some people are just fixated on numbers, so anything less than 1gb is a "disappointment" for them.

    Thankfully, Apple is fixated on performance rather than specs. :)

    agreed.

    i'm more interested in performance than figures. and performance wise it looks so sweet. if it doesn't match the spec of it's competitors i couldn't care less. it's still way ahead.

    Just view Tuesdays presentation and watch the demos of iMovie and Garage Band on the iPad.
    iOS is about small fast and efficient software. More ram will help but the iPad 1 was already a nippy little beast.

    Since there's still no true multitasking, for which more memory would be essential, 512mb should be sufficient to run anything that the App Store will sell you.

    haha no no. i'm not saying it's slow. i watched the video it's amazingly fast.

    i'm just wondering what does the ram do and why people keep asking about it like on engadget's comments.

    ram literally helps runs things even faster (or smoother). it's all buffered a lot faster within memory.

    engadget's posters are probably techy minded and sticklers for details and just want to know and moan about it :p most average peeps wont know/care. and why should they?

    @ drag - what is 'true multitasking'? the ios does multitasking.

    Ram is the memory type which stores your active data. Ram communicates with the cpu much faster than the internal memory.
    Example when you boot a computer you actually transfer the operation system from your hardrive to your ram.
    You can think of ram this way. The more ram you have, the more multitasking you get. But again what also matters if how good your software uses the ram

    Could someone explain to me how, if there is no true multitasking, that a dual core CPU would be of benefit?

    The processor determines the rate at which data is moved from point A to point B while being rearranged to meet the visual target. An example is changing the 0s and 1s stored in the memory into a song and the album cover you see. The data moves at different rates while it is happening. But say you are watching a HD movie. There are going to be times that the processor might get bogged down due to the demands of the video. What RAM does is when the processor is not busy, it allows the video to get ahead of itself, so that you have less interruptions.

    True multitasking is when something is continueing in the background while you work on something else. Again the video analogy. If you were watching a video on the web and switched to another program for a few minutes, under iOS, the video would freeze at the point you switched over, and resume when you switched back. Under true multitasking, the video would continue to play the entire time.

    These are just rough examples and it gets a little more complex in reality. for example, you can play music while surfing the web, and other items that are a combination of both. It all has to do with dealing with managing what the processor does when, so that everything runs smooth and effortless for the user. With true multitasking, they either have to have a very good OS to manage the assignment of data to the processor, or they have to over power the process.

    If you ever go skiing in the winter, think about how they manage the lift lines when busy. It is the same basic operation. The skiers are data, the lift operators are the OS, and the lift is the processor. If you have eight lines waiting, they will fill all the chairs from several lines at once, but the skiers have to wait their turn according to the priority establish by the operator. When there is only one line, the first in line get seated first. One way to speed up a one line operation would be to go from two seats to four seats. That would be the equivalent of going from a single core to a duo core.

    It is true, this is how MS OS works. Not overly efficient, more memory better performance. iOS does not operate this way. Check it out.

    Very good explanations of ram. I also believe that more ram is not necessarily as important on a tablet, than it is on a Desktop or laptop pc with spinning hard drives. The Ipad has solid state storage.

    Let's put it this way. PlayStation 3 and Xbox 360 have about 512MB. Look what those machines are capable of when people use the systems potential. Memory may be a problem but in iPad's case I doubt it will have any issues specially with 512MB.

    can we then assume....

    Can we then assume that because of the CPU/GPU improvements from iPad 1 to iPad 2 that watching .avi or mkv hi-def videos will be improved? Right now it's a no-go with my iPhone 3gs and vlc media player. I can only watch small avi files.

    Not technically true, applications and OS can only run in RAM so RAM is required regardless of which type of storage is used. More RAM is required to run larger applications or a higher number of concurrent applications but extra RAM can also be beneficial in caching data from storage if it is likely to be required by the cpu. The type of storage doesn't have an impact on the amount of RAM required although can still have an impact on performance depending on access time and throughput of the storage used.

    I read one of the reviews of the iPad 2 which stated that large AVI support was improved in OPlayer over the original iPad so I would assume VLC would show improvement too.

    Ram will help everything go smoother. The 256mb in the ipad 1 was just not enough - especially when they added their version of multi-tasking. All those problems where apps wont start unless you reboot the iPad are memory related. I think 512mb will make a huge difference but wish it was even more. Guess they had to save something for the iPad 3 :)
