With all the rumors about quad and dual core processors, what are your thoughts on what we'll see in march?
CPU: Dual-core next gen ARM (e.g. CortexA15)
GPU: Quad-core next gen PowerVR
RAM: 1GB
Would be massively hotness IMO.
Screw the quad core CPU, not relevant for mobile apps IMO.
Well, best-case scenario would be this:Well, if the A6 were to include the new PowerVR G6 series GPU, and if the iPad 3 included the A6, it could have up to 20x the graphic power of the iPad 2.
The current PowerVR 5 series dual core GPU found in the iPad2 and iPhone 4S is actually quite old (still currently top of the line).
Pair the new GPU with a quad core ARM and you have one hell of a system on a chip. I'm expecting the iPad 3 and iPhone 5 to pretty much blow any other mobile device completely out of the water in terms of power.
CPU possibilities:
I only see two real possibilities: the dual core 1 GHz A15 variant, or a quad core Cortex A9 1 GHz variant.
GPU? The current iPad 2 has a dual-core GPU. I think they will either use a quad-core version of this GPU, or a completely new one.
I think people will be disappointed with a Cortex A15 1 GHz dual-core processor, because people will think the performance has not changed. Quad-core just 'sounds' better.Any chance they will go with a quad core Cortex A-9 and a quad core version of the current PowerVR SGX543MP2 ?? I would not think that combo would impress.
That makes me hope the report from Verge is right. If it's gonna be a dual core then it most likely will be the Cortex A15

i bet apple will throw in a dual-core, and people will bitch like crazy, and it will work perfectly.
Oh, and there is no doubt a dual-core 1 GHz Cortex A15 processor is much better than a quad-core 1 GHz Cortex A9 processor. The first one will boost performance for all applications. A quad-core Cortex A9 processor, would only be benefitial for multi-core aware apps - and most apps in the App Store are single-core and some dual-core.
The performance of iOS (as a system) is just fine. Sure multiple cores is better for multitasking, but two cores do just fine right now.You really have no idea. iOS has GCD architecture that allows an app to optimize its performance for an arbitrary number of cores, from one to a zillion and a half. Any app that wants ideal performance will be written for GCD so that it will not have to be recoded to run well on iPad 9.
Apps that would not especially benefit from parallel processing will just not benefit. But iOS also runs more than one process at a time, so more cores might improve the performance of the underlying OS.
Quad-core is only useful for developers with the knowledge and skills and for true multitasking.
