quote: Fact is, until we have measurements comparing the 64bit version to the 32bit version of the same app, none of us have any idea what the benefits are, if any. I am a software engineer, and while I understand your points, I would be surprised if the benefits were anywhere close to being as relevant as you expect them to be. Primarily because you're ignoring the fact that moving to 64bits also brings with it a host of drawbacks, which could easily cancel out many if not all of the potential performance gains, particularly on a low-power ARM CPU with modest amounts of cache and a frugal pre-fetcher...
quote: Please, enlighten us on the benefits of 64bit on a phone with tiny (fart) apps and very little memory to address. One day it will be a benefit, but that day is long off especially with a functionally retarded OS like iOS.
quote: I re-iterate the question (with the snotty part removed). You quoted it and didn't answer it in any way. What does 64 bit do on a phone with so little RAM?
quote: The biggest surprise for me was the announcement that the new A7 processor in the iPhone 5S is the worlds first 64 bit processor in a smart phone. We heard this rumor early on but I dismissed it thinking it would be too soon to move to 64 bit. Apple, however, believes it is the right time.1 billion transistors. That is truly remarkable. I’m not going to go into the depth’s of 64 bit architectures but I’ll make a few points on why this is a big deal.First, 64 bit will dramatically increase the performance of more intensive and demanding applications. Things like audio and video encoding / decoding and any graphically intense applications including games and other visually complex applications. I talked to several prominent developers in the crowd who were extremely excited about the possibilities with 64 bit computing in mobile devices.What makes this move to 64 bit all that more interesting is the software. iOS 7 is the worlds first 64 bit mobile operating system. The key to 64 bit processors is to have software which is written to take advantage of it. Here again is where we see Apple’s vertical advantage kick in. They control the hardware, design the SoC, and control the software. All these things have led them to create the worlds most advanced processor and operating system. But it is not just about Apple.Apple likes to do things that give developers a distinct advantage for their apps on iOS. 64 bit will do just that and I am excited to see how developers can take advantage of the A7 and create the most amazing smartphone applications ever created.The A7 and 64 bit, and potentially the results it yields in terms of third party software, gives Apple a distinct time advantage over competitors. No competitors are even close to bringing 64 bit and even for some platforms like Android which is focused on the low end non-spec smartphones, it may not even make sense.

quote: Sorry Tony, but phones are not valid game devices. A game device is one either purchased for or built specifically for gaming. The iPhone is neither of those things and if we are looking at the total number of units sold, then the Playstation 2 leads the pack with 157 million units sold over its lifetime.
quote: what most people don't realize is this is just apple's way of saying..oooh, that app is 64 bit only.. your iphone1-iphone 5,5c won't run that..here, buy this new one!! it does!!
quote: 64 bit is nice to have before you hit that addressable range limit because it gives people time to start writing code for 64bit processors
quote: This is just a custom version of the existing ARMv8 architecture
quote: It's not like Apple invented the 64bit ARM SoC
quote: However the reason they are, is because nobody else sees the point in doing so for a smartphone
quote: and introduces several new problems. Like now having a fragmented app store of 32 and 64bit apps
