    I had been expecting some kind of pipe cleaner for Samsung's 32nm process. Though I have to admit a 32nm A5 specifically for the Apple TV wasn't what I had in mind. Reply

    Apple TV 3, and iPad 2,4 (lower cost model), so it isn't as much of a one-off as it seems superficially I guess.

    Any chance AT can get their hands on one? I wonder how much 32nm will change the iPads batter life, and if the 2012 iPad will also be moved to 32nm silently. Reply

    I would guess that the screen dominates the battery life for all iPads, so I wouldn't expect a huge improvement in battery life. Reply

    Unless I am mistaken, this is Samsung's first shipping 32nm part, no? They haven't shipped any 32nm parts in their own phones yet. Reply

    Your previous AppleTV 3 review noted that the 32nm A5 uses a 32-bit 512MB LPDDR2 die, so you can probably note in this article that not only was 1 CPU core disabled, but 1 32-bit memory controller was as well.

    I don't suppose there's anyway to check if one of the GPU cores is also disabled? Given it won't be running games or other GPU intensive apps and video decode is done by a separate subunit, presumably 1 SGX543 would be enough for the AppleTV.

    Single core A5 800mhz - 1ghz (kind of like a turbocharged A4?):
    - AppleTV
    - iPod Touch
    - iPhone 4 (potentially - if harvesting A5s is cheaper than the old A4)

    Dual core A5 1ghz:
    - iPad 2
    - iPad mini
    - iPhone 4S

    Dual core A5 1+ ghz (possible with die shrink, right?):
    - iPhone 5 (backup option in case A6 or A5x not ready for smartphone use)

    I think we'll see all 2012-released iOS devices using this chip by the end of the year - including the iPad. Just a matter of processor speed and cores.

    Would quietly replacing the Cortex A8 based A4 with a single-core A5 break anything?

    I bet a 32nm iPad4 will have a 1.25GHz CPU! Reply

    hey Anand, i was wondering when there is a jailbreak available for the apple tv, is it possible for developers to some how come up with a way to utilize both cores? I know that android releases there source code while apple is more locked down than fort Knox. Anyway, i was hoping you or any of the other qualified writers (and many overly qualified commenters) could clear the air for me. Ive also noticed that no tech blogs have really come out with articles on what possible future jailbreaks for the new apple tv could do to utilize that dorment core. Thanks again! (btw this the verge, engadget, androidandme, and droid-life = best tech sites :) ) Reply

    One of the first aspects of a home security camera to consider is whether you will use a wireless home security system or one that requires connection to a power source. There are many security camera options that are wireless.
