The Impact of Larger Memory

Apple doubled memory capacity on the new iPad to 1GB, marking the first time in recent history that Apple's flagship product offers a similar amount of memory to the current crop of high-end Android devices. Apple's iOS can do a relatively good job with limited system memory as it will conservatively unload applications from memory in the event that it needs to free up more space. iOS does not support paging to flash, making DRAM size a hard limit for developers looking to really push the platform.

Apple has always been conservative on DRAM sizing because it's a great way of reducing the BOM (Bill of Materials) cost. If Apple can make up for having less DRAM by being more aggressive in software (read: kicking apps out of memory), it's a tradeoff that makes sense. It's really Apple's foray into gaming that has added pressure to increase memory sizes.

With the move to the Retina Display, the amount of memory needed to store a single frame increases by 4x—from 3MB to 12MB. Assuming two buffered frames you're looking at 24MB of RAM just to smoothly display what you're seeing on the screen.

The bigger problem isn't the frame buffer, but rather all of the other data you need (e.g. level data, textures, etc...). The higher the screen resolution, the more important it is to have higher quality assets in your game. Texture compression can go a long way, but at some point there's simply more data to deal with as game complexity increases. It's not just about the increase in resolution either. As GPU horsepower increases, so will the complexity of what game developers try to build.

While the frame buffer size increased thanks to the Retina Display, total system memory increased by a much larger amount. With 1GB of memory, game developers are now less constrained.

A more immediate benefit is apps and web pages will remain resident in memory longer as you open open up and switch to other apps. For example, on the iPad 2 if I open four tabs in Safari (AT, Engadget, Reddit, and Tech Report), open iPhoto, run Infinity Blade 2 and GTA 3, switching between the latter two will always require a full game reload (as in you see the intro and everything before you pick up where you left off). On the new iPad, with the same setup, I can switch between Infinity Blade 2 and GTA 3 and automatically resume where I last left off thanks to the extra DRAM. You can still create a scenario where even 1GB isn't enough, it's just that the limit is now higher than it was on the iPad 2.

    I have to be honest, after reading through that link I didn't see anything that even implied working conditions had anything to do with the suicides of the factory workers. The only suicide for which there was any real information provided was that of the worker who killed himself after losing the iPhone prototype, and in that case the victim wasn't a factory worker, but someone in logistics.

    Did working conditions have anything to do with the factory worker suicides? Maybe, maybe not. There doesn't appear to be evidence either way.

    I posted the Wikipedia link for all the links in the reference section.

    Here's a more direct report: http://sacom.hk/wp-content/uploads/2010/11/report-...

    And a companion video: http://vimeo.com/17558439

    The video includes an interview of a survivor who is now paralyzed waist down.

    You can choose to patiently read and watch this report or just turn a blind eye like a lot of people do.

    I did read the report. It details unbelievably miserable working conditions in the factories, which I don't think anyone is disputing, and concludes that the way to change those conditions is to pressure the electronics companies making the bulk of the profits. None of the above comments dispute any of this. However it does not link working conditions to suicides among factory workers.

    And yet you continue to insist that there is a link, with no evidence to back it up. You make statements like, "over a hundred of them have committed suicide over the working conditions," "...scores of people killing themselves citing poor working conditions," and "there is no disputing the fact that these deaths are related to working conditions," but you provide only conjecture to back it up, no proof. When you do this people start dismissing everything you say out of hand, even the things that are accurate. And worse than that, you run the risk that other people arguing for better working conditions will be tarred with the same brush. Look at what happened to Mike Daisy.

    Again, I'm not saying working conditions didn't contribute to the suicides, I'm saying there is no evidence one way or the other. Until you have evidence (in the form of suicide notes, higher suicide rates among factory workers, etc.) please stop. You may actually be hurting the very movement you're trying to help.

    Well, I'm sorry if it is inconvenient for you that these individuals have not said it in so many words. Should we expect them to?... Hey, by the way, I know you're going to kill yourself but why don't your write down an explanation first so we can conclusivly say what the reasons are. And even though you are under a lot of stress right now and are clearly not thinking straight SPELL it our for me please...

    Evidence can come in different forms. Not all of it is directly incriminating, in which case the attention turns to the circumstances. So if these reports don't establish a reasonbly clear coorelation to you, then I am sorry but I disagree.

    You can nitpick on specific words in my comments and quible about words such as evidence. But what are you accomplishing here? Are you justifying your own guilt of purchasing a device manufactured here? Are you an Apple or Foxconn mouthpeice? Do they pay your for spreading lies like Foxconn factories are actually a good place to work (which has been said in the previous comments)? Really, it is people like you need to STOP.

    I'm not going to stop saying what I believe is right!! And unlike Mike Daisy I have not fabricated any evidence. At the most, you can complain that I have drawn incorrect conclusions and I am saying the same about you.

    It's inconvenient for me that you are lying. You're the one saying that there are, "...scores of people killing themselves citing poor working conditions," not me. Either show me a case where those people who killed themselves cited poor working conditions as the reason, or cease claiming it is fact. You do damage to the movement that's trying to improve things.

    People hear the news reports about Mike Daisy lying to Ira Glass and what they take away is not the specific lies (claiming to witness things had actually happened but that he had only read about), it's that he's a liar and the story wasn't true. They dismiss the whole issue of poor working conditions out of hand. That's what you risk when you lie to get people to listen.

    Go ahead, nitpick on specific phrases and completely lose the meaning. But the problem is easily corrected. One can argue that citing something does not have to be done on paper as you would in a professional article. To me the workers "cite" the existence of a problem through their actions as words have failed them.

    Still if you want me to rephrase I'll say "scores of people killing themselves in midst of poor working conditions.." Can you prove that this statement is inaccurate??

    And while you ask me for evidence have you ever bothered to see if you can find evidence that these deaths are not related to working conditions. Prove it to me and I'll take back everything I said.
  • PeteH - Thursday, April 5, 2012 - link

    I think you missed the places above where I stated, "I'm not saying working conditions didn't contribute to the suicides, I'm saying there is no evidence one way or the other." That was my whole point. And I did explicitly state that there's no disputing the poor working conditions. So no, I have no problem with your revised statement.

    However, I don't think what I did was nitpicking at all. Nitpicking would be pointing out that a score is 20, so scores would imply at least 40, and I've only seen documentation of 17 suicides (I haven't seen numbers pre-2010). But that's not what I did.

    Manufacturing employees?

    Look at the world! There are about 20 countries in the world that are democratic and have great living standards. Its just 100 years ago since these countries had child workers and harsh condition.

    BTW. My county is on the "top countries" in the world. Still we have the largest suicide rate in our population in the world. Why are you not fighting against the Swedish government that drives thousands to kill them self each year? We live like slaves here with 80% taxes.

    BTW. Do you care if other companies use HonHai/FoxConn or is it just Apple? Are you writing the same thing about Dell/HP and all other companies that use FoxConn?

    What have you done?
    Have you donated money to a chinese worker? Or is Trolling the only thing you manage to do?

    I was curious about this statement. Could you elaborate. What inconsistency is there?

    "On the iPhone Apple has been entirely too lax about maintaining consistency between suppliers. If it wants to be taken seriously in this space Apple needs to ensure a consistent experience across all of its component vendors."

    I remember an ad that touted something new to "see and touch". The retina screen is the "see" part but what about the "touch"? Was that just a gimmick meaning you could touch the screen, or is there some sort of different feel to the screen?
