Single-core A5 CPU in new 1080p Apple TV doubles RAM to 512MB

in iPod + iTunes + AppleTV edited January 2014


A teardown of the new 1080p-capable Apple TV has found that its single-core A5 processor features the same 8 gigabytes of memory, but doubles the RAM of its predecessor to 512 megabytes.



The new Apple TV features a custom-built A5 processor that, unlike the A5 CPU found in the iPhone 4S or iPad 2, features only a single processing core, instead of two. But while Apple removed one of the cores from the CPU, it left the RAM at 512 megabytes, according to a teardown of the device conducted by XBMC community member "aicjofs" (via MacRumors).



The RAM in the new Apple TV is built by Hynix, and is believed to be the same memory utilized in the Amazon Kindle Fire tablet.



While the RAM has been given an upgrade, the internal flash memory, which is used to cache video files when they are streamed, remains static at 8 gigabytes.



The updated set-top box is also said to feature a second antenna that its predecessor did not have. Its exact purpose is unknown, but it was suggested that the antenna could be to improve Wi-Fi connectivity and speed.



The previous Apple TV, which was capable of outputting 720p high-definition video, ran on the A4 processor that is found in the iPhone 4 and first-generation iPad. The previous Apple TV featured 256 megabytes of RAM.











Meanwhile, the new iPad features a unique A5X CPU that has even more RAM, with a gigabyte of onboard memory. The dual-core CPU also features a new quad-core embedded graphics processor that gives the new iPad even greater graphical capabilities.



Together, the new iPad can stream 1080p high-definition video over AirPlay to the new Apple TV, allowing users to watch high-quality content on their HDTV.

    1) Since iTunes Store 1080p isn't much larger than its 720p due to the new profile used this makes sense.



    2) I wanted an AppleTV SDK and App Store in the past but I now think this is best handled with the upgrades Apple has made to AirPlay

    Perhaps they have also added an additional 802.11n spatial stream. It seems highly unlikely that they added 802.11ac to their hobby, first.

    512MB is not enough RAM for people who measure their self esteem in gigabytes

    I wish there was a way to stream the content ad hoc to the atv instead of it having to travel via the router, don't see why radio waves have to travel all around the house via my baby sons room, instead of just pushing play and leaving the iPad close to the atv, although I appreciate the technical difficulty in achieving this.



    Anyway the atv has come to its own, or come close to its own with this release, it remains to be seen what apple plans to do with the rumoured tv set, I hope atv stays as a stand alone product as well.

    Are ther any routers or pcs with 802.11ac yet? Is it still a provisional standard or is it close to finalisation?

    Hopefully the extra antenna solves the problem with my second ATV in my back bedroom. Even though it is next to an Airport Express which is set up to extend my network it loads extrememly / painfully slowly from my iTunes library. This is a severe flaw that is mentioned frequently on discussion boards.

    For most people, "memory" and "RAM" are synonymous, so saying it has 8GB of memory and 512MB of RAM is a bit confusing.



    Why not describe the 8GB as "storage" or "flash"?

    Having purchased the new Apple TV for the sole reason of streaming the contents of my iPad2 to my home theater I was disappointed to find poor data transfer rates. Music videos do not play smoothly and frequently stop. I have not worked though this issue at this time and will report back once I find the exact problem/solution.

    Just paper your son's room with aluminum foil. That's really what it was meant for. If you have any left over, make everyone in your family a tin foil hat.

    I was going to make a similar comment. I can't wait for all the people who say Apple has lots of money and should have had a quad core processor in this thing - and 32 GB of storage.

    That should help with debug. In any event Ethernet is a good thing, people often expect to much from WiFi.

    Wifi will have zero effect on your child's brain or upbringing. Any evidence to the contrary is usually just real science being misinterpreted/misappropriated by people who want to sell you stuff. If the energy was intense enough to interface with organic systems we probably would have evolved the ability to see (or otherwise perceive) background micro-wave radiation in the natural environment. Only reason micro-waves ovens cook food is because they are a very specific frequency which is able to ?wobble? an intra-molecular bond inside water molecules.



    Advertisers know anxiety is the primary emotion that drives parents to purchase. Don?t be conned.

    You're not doing anyone any favors by being so misinformed.



    If you're so worried about the WiFi radiation, why don't you move the access point to a more central location? Or just turn it off if you really think it does damage.



    If you meant to get around bandwidth and signal degradation, I don't know why Apple doesn't have more ad-hoc capability. But you'd still have that distance limitation when you want to stream media from the internet.

    I called it . I figured they'd silent release the extended range like the airports. *pats self on back*

    I had a similar problem in my daughters room. Thats the only one that uses my airport express as an extender- and it gets slow- the new ATV I can happily report is lightning fast in comparison. In fact- all locations are better. Very happy with these upgrades (albiet small ones).

    I picked up the 3rd gen Apple TV over the weekend and I have to say I really like the speed bump from the 2nd gen version. Even with a single core, the difference in speed between the A4 and the A5 is noticeable. My problem with it is that there isn't a interlacer hidden in the circuitry which means it can't do 1080i to my classic 65" Mitsubishi. So it's falling back to 480p which really sucks (my TV doesn't do 720p from external sources).



    This means that I either have to take it back to the store or upgrade my classic receiver (built before HDMI switching and built in scalers). It's going to sting to end up spending upwards of $1000 to satisfy a $99 device (my wife won't let me replace the TV for another couple of years).

    tell your wife you are going to buy a new sports car instead.... Then after a few days, tell her you will settle for the new TV.

    I picked up the new ATV on Friday when I got the new iPad. Setup was easy and it worked flawlessly until Sunday when I rented a movie from iTunes. I started to see flashes of white at the bottom of the screen and the occasional audio stutter. Late Sunday night I decided to track down the issue to see if it was in the saved download or something else. It was both - as I could rewind the movie and sometimes replicate the flash in the exact same spot and sometimes not.



    I did all of the standard fixes (resetting, soft and hard reboots, etc.). By Monday morning (this morning) the flashes were occurring with great frequency and not just when viewing the rental movie.



    Apple tech support walked me through the video settings (which were initially set to Auto) and it turned out that ATV was having difficulty displaying at 1080p 60 Hz, while 720p 60Hz was fine. This points to a hardware failure and the unit will be returning to the store for a replacement.



    I'm just curious if anyone else has seen this issue (Apple tech said it was new to them)?

    An HDTV that can't take 720p sounds like it's about 10 years old maybe. It does look like they took away the 1080i for this model.



    $1000 gets a pretty sizable TV, $1500 replaces the TV with a new Mitsu of the same size.



    It might be simpler to get the previous AppleTV, unless you were intending to get a new receiver anyway. I'd check the Apple online store for refurbished versions of the previous model from time to time. They're out right now, but I'm sure more will keep trickling in.

    I am very well informed thank you very much on the effects of non ionizing radiation, or just enough to not be on the receiving end of average worn sarcasm by the average joe. I will not reveal my major for privacy reasons, but I have friends in both the electrical and biological sciences who are also convinced of the potential dangers cell phone radiation poses, the vested interests hindering more robust research, and the available long term studies pointing to brain tumors after a threshold of long term cell phone use. I am also aware that wifi poses a minimal risk as compared to cell phone em radiation. I am no alarmist, but I have my concerns.



    I have turned it off at times, and I 've also considered ethernet; unfortunately a more central placement of the router would mean the bedrooms at the back would suffer from signal reception, but for this I am considering and augmenter at the back.



    Bandwidth and signal degradations are also issues as you point out. I would think a more ad hoc way of connecting the ipad to the atv would be very useful. Why steam web content say from the router to the ipad, then stream it back via airplay to the router to be streamed in turn to the atv? If I understand this correctly, this is what's happening. I appreciate it's technically much easier to use the established wifi network via the router to centralize the process.
