  • iPhone 4 Has 512MB RAM

    Confirmation that the new iPhone has twice the RAM of the iPad or the iPhone 3GS has come from a recently released video of a developer session at WWDC 10. MacRumors first reported the revelation, which is the first acknowledgement from Apple that iPhone 4 has 512MB of RAM.

    For a company that loves to dish out specs (highest pixel density of any smartphone, most energy efficient desktop, etc.), Apple sure is reticent when it comes to the amount of RAM in an iPhone. They've never publicized the memory specs, ever, and so we've had to wait for teardowns or leaks to find out, for, example, that the 3GS has 256MB of RAM. In the case of the iPhone 4, the assumption has been that the production phone has 256MB RAM, because that's how much memory was installed in the "lost-and-found" prototype when Gizmodo cracked it open, and how much the A4 chip on the iPad has.

    Video of the session where the RAM capacity was revealed, Advanced Performance Optimization on iPhone OS part 2, was recently released to registered Apple developers for download via iTunes, but is not presently available due to high demand.

    As MacRumors notes, this may explain why iMovie will only run on iPhone 4, and not the iPad.

      Thats a lot for a smart phone

      Give it one month and HTC is gonna come out with a phone that has 1GB of ram.. Watch.

      Apparently all HTC likes to do it just go a lttle better from what Apple does. And they still make ****** phones

      I was feeling semi-disappointed that the HTC EVO still had double the ram of the iPhone 4...but this is awesome news. I can't wait for this phone.

      It was so slow that I had to bust out one of my old iphones and use it as a TEST phone.

      512 is going to be real nice!

      Do you think there will be ip4's sold in the store even though they ran out of pre orders?

      On a side note, I might wait for the white one, its not gonna show grease nearly as bad as the black one, and the white parts are under the glass, so dirt wont be a problem. Im also waiting to see how scratch resistant the glass will be.

      The invisishield should be alot easier to install thanks to the flat surface!

      This is good stuff..bigger ram is good.. A4 with 512MB is perfect combo..Now we
      need to know what the A4 will clock at for sure..that's the other thing we need to confirm..

      dr0herb- 100%. You really think they wouldn't?

      Pre order stock = seperate from launch day stock.

      Yeah I can't wait. This is going to be very nice indeed. I was using my mates iPad the other day (first time I'd tinkered with one), and yeah, it just felt like an oversized iPod Touch as mikerlx wrote, but I have to admit, it was blasingly fast. I could seriously tell the difference - my iPhone 3G is painfully slow now, it just can't handle anything winterboard wise.

      The 512MB of ram s most likely because of the multi tasking.

      I hope this is true - it will make the multitasking much better.
      I was a bit scared that it'd struggle!
