Apple iPhone 5 To Flaunt New A8 Processor
An anonymous reader writes "The release of iOS 4.3 beta for developers has revealed updates to gesture-based navigation, AirPlay and Personal Hot Spot in the next edition of iPad and iPhone. However, not all changes are UI-related; it is reported that Apple is due to add an ARM Cortex A8 processor to its iPhone 5. Apple Daily, a Hong Kong-based newspaper, reported that Apple's iPhone 5 will be powered by a dual core processor with SGX543 graphics. It is reported that Apple is in contact with a Taiwanese component maker for the A8 SoC. Currently Apple uses a custom made A4 SoC in its iPad and iPhone 4 and uses SGX535 graphics and video support."
Uh, the A8 is ARM's old smartphone core. Putting two of them in a package is a little bit clever because, unlike the A9 that everyone else's next generation products are using, the A8 isn't actually designed for multicore applications (the A9 scales to 4 cores).

A4 uses a Cortex A8 processor. A4 is the marketing term for their SoC, (Cortex A8 @ 1ghz(800ish mhz on iPhone 4) + PowerVR 430). The next version will probably have a Cortex A9 based chip.
Yes, the N900.
And the Palm Pre.
And the Motorola DROID, Droid X, DROID 2, and DROID PRO.
iPhone 3Gs, iPad, iPhone 4, iPods, and Apple TV.
Pretty much every non-Qualcomm based phone currently runs on Cortex-A8 based CPUs.
I expect to see this post modded +5 informative once the iPhone 5 is out.

A very heavily modified A8. Qualcomm licensed the A8, but then ripped out the floating point pipeline and replaced it with something better, tweaked the rest of the pipeline in a few places and branded it Scorpion. It generally ships in their Snapdragon SoC. It's somewhere between the A8 and A9 in performance for most workloads.
ARM provides a variety of different licenses. The cheapest just let you take their core, pop it in the middle of a chip and put other cores around out (or fab it by itself). The most expensive ones give you all of the designs and the right to modify them in any way you like. Qualcomm is one of the few companies with the latter kind.
Most SoC makers get the cheaper ones and differentiate their products by adding different components to the ARM core. For example, the TI OMAP series comes with a TI DSP that provides a lot more performance (and a huge amount more performance-per-Watt) for a lot of media decoding tasks, nVidia's Tegra series comes with an nVidia GPU.
Qualcomm modifies the ARM core itself, which means that it takes them longer to get to market but gives better performance. It also has the effect that they are out of phase with the rest of the market. Everyone else was shipping A8s before the Snapdragon was out, but then Snapdragon (which outperforms the A8) came out before anyone was shipping A9 cores. They will probably do something similar with the A9 and bring their tweaked version to market just as the A9 is starting to show its age.
The other interesting company is Marvell. They have a license from ARM that allows them to modify ARM chips or produce their own independently designed ARM-compatible chips. They bought the XScale line from Intel, which is based on the StrongARM design from Digital. They make the chips in the SheevaPlug and similar systems, which are not ARM designs.

Holy shit they're stupid.
Seriously. Who doesn't know that the A4 contains an A8 and that the A8 (the new A8, not the other A8 in the A4) will contain an A9? Shit, I learned that in pre-school.

You really have to hand it to Apple: Very few other companies garner headlines for what amounts to "Pre-release software build indicates that version N+1 of product X will incorporate version N+1 of the assorted off-the-shelf hardware that went into version N".
Seriously. There is a reasonably limited set of companies with performance-oriented ARM SoC designs. There is a similarly fairly limited set of GPU options for power constrained scenarios. Shockingly enough, Apple(just like everybody else) is pretty much going to combine the most recent one of each that they can shoehorn into their design and production process and go from there.
In other news, the next Mac Pro will probably have a newly released Xeon in it...
This is correct. Apple's new processor will be named A5 and is a multi-code Cortex A9 processer. It will reportedly have dual-core SGX543 graphics, up from the A4's single SGX535 GPU, which means that in theory you could do 1080p on the device no problems at all. They are also replacing the Infineon chipset with a Qualcomm chipset that does both CDMA/GSM/UMTS.
I still cannot find the droids I am looking for...
If you have pop-ups enabled, it appears in the middle of your screen as it happens. You click on the pop-up to get to the message. Going back is a bit more convoluted. You have to tap the home button twice to bring up the list of running applications, then tap the app you were in to go back. It's not bad, though the double-tap of the home button for multitasking is not that intuitive.
Remember, though, that Android and other platforms are building from what was learned on iOS. The closest thing to an iOS type operating system was Palm, and there are many reasons why that was light years different. Don't get me started on the royal crap that was smartphones at the time of the iPhone launch.
It's a bit like The Matrix. If you go back and re-watch it now, you have to wonder what was so special about it. "They're doing eastern mysticism, hong-kong kung-fu wirework, and slow-mo fight scenes. So what? Every movie does that." Well yes, every movie does that because they're all based on The Matrix. Similarly, there are several good portable smartphone operating system choices out there, which all do certain things better than iOS. They all also happen to exist because they copied iOS. And then they built out, did some things better, and became their own animals. But credit where credit is due: nobody was copying Windows Mobile 6. Everyone built from the basis established in iOS.
