Re: The iPhone thread
 
Some, or all?


Didn't have to get all new apps when the iPad 2 and iPhone 4S went dual-core with the "Apple A5", or when the iPad 3 gained a quad-core GPU with the "Apple A5X".

Some apps did get updated (for free) to take proper advantage of the improved CPU and/or GPU, but there was no general "everything needs to be updated". I don't know how much of it is handled by iOS itself being updated to handled the increased core count.

I don't know myself i was just reading this, actually the bit i understand is quite interesting:)

According to apple all the old apps will run on the new iPhone 5 but they can be adjusted to take into account the extra height and better A6 chip which is said to be 2x faster in most applications. All this and more can be seen via ITunes, Podcast, Apple Keynotes/Apple Special Events/September 2012.m4v

Its looking good but I think I will wait until they bring the next faster one out. I am a little concerned in the thickness of the new iPhone. Will it break, I have had the sceen go on my 4s which cost £139.00 to replace :erm:

Interesting link :)


That's again more speculation that it's "still dual-core"... but using newer and faster architecture. Ties with what AnandTech has been saying.

New ARM Cortex-A15 CPU, instead of sticking with the A9, and a new "series 6" PowerVR GPU, instead of sticking with the "series 5XT" SGX543MP2/4.

Makes sense... Why try and cram extra cores in, when you can have the same number of cores but use ones that are newer and faster. Still get the performance increase, but without the size of power issues, and without apps needing to be re-optimised to use four cores.

That's what i picked up on ,more is not always better and haven't i phones had issues in the past with power usage and heat buildup ?.One of the things i was curious about was how do they keep modern smartphones cool with multiple cores

I'm loving how they managed to catch Hulk Hogan out as well :D

Nope. For one thing, apps optimised for 1 or 2 cores won't suddenly stop working. They just won't use the extra cores.

For another thing, Apple are surprisingly good at persuading app developers to use new features in their devices. They also don't allow developers to charge for updates. They can, however, stop development on the old app and release a new one (as ALK did with Copilot Live).

Further speculation on the specs...

http://www.anandtech.com/show/6292/i...15-custom-core

Not an Apple design based on the "off the shelf" ARM Cortex-A9 or A15, but a brand-new ARM-based chip designed by Apple, using the ARMv7s architecture. Similar to the A15, but custom designed by Apple.

As iOS uses Grand Central Dispatch, as long as the app is written correctly the OS should automatically use however many cores each device has.

Thanks how long does it take to install as this is my 1st iPhone. Course my mates told me it takes about half a day

The last update I had took about half an hour.

Just make sure that you have backed up your phone beforehand, using iCloud and/or iTunes.
