    Or how much extra ram will be available on the new iPad after allowing for the new screen?

    Why exactly is this important? If it works and it works well, what's a number going to do?

    3 meg. W x H x bits per pixel / 8. Keep in mind this is just one frame buffer. Most apps will use double or triple buffering (multiple copies of the frame buffer) to render into and then switch on a vsync to avoid tearing artifacts. As far as textures etc, that is up to each individual app.

    Look at it this way:

    Double the resolution, double the RAM of that in iPad 2 + beefier GPU.

    Yeah, except it's four times the pixels.

    Agreed.

    The point of the question is to try to find out if it will work ok or perhaps be worse than the iPad 2.

    I don't think this is right. Way more then 3 mb.

    It's 12 MB, no?

    2048x1536x4(32 bit color)

    The 3 mb is how much memory is needed to address each pixel in the display. That was based on 8 bpp. It could be 12 mb if it's 32 bpp.

    Buy it, try it, and if you don't like it, return it. Simple. Do you actually think Apple will release a new hardware version that doesn't at least perform as well as the previous version?

    Your right. I had a brain fart. It's been many years since i worked on video drivers.

    Ah my bad, iPad doesn't have 32 bit but uses 16? Or possibly 24?


    I was trying to figure it out... The memory in the iPad couldnt handle 32 bit color at that res (as far as I know)

    Edit: it's 24 bit.

    True. Thanks for the catch. I meant 2x resolution.
