ARM categorized to 3 parts of Cortex Processors which are :
Cortex-A family : using for high performance devices (Smartphones and Tablets)
Cortex-R family : using for real time devices
Cortex-M family : using for Embedded systems
<<classification of ARM CPU >>
But only the ARM Processors having MDK-ARM Microcontroller Development Kit containing a complete software development environment for Cortex™-M, Cortex-R4, ARM7™ and ARM9™ processor-based devices which Support Windows.

What type of processor does the XDAII use, ARM or MIPS?
The xda2 uses the pxa263 processor, this is an arm compatable chip afaik. The mips processor in pocket pc is a dead end, there is no upgrade path for these via new releases of firmware.
not sure if it also goes for pocketpc2000 but at least 2002 is not made for mips
arm and excale which are code compatible are the only cpu's currently supportet by pocketpc
When it comes to buying software it's the ARM version you need for the XDA II.

Today at Mobile World Congress, Texas Instruments Incorporated (TI) (NYSE: TXN) announced it will demonstrate an early look of the Android mobile platform in two forms: a prototype handset based on TI's OMAP850 processor that also includes TI's Wireless LAN (WLAN) and Bluetooth® wireless technology solutions, as well as an OMAP3430 processor-based Zoom Mobile Development Kit from Logic PD. Both demonstrations highlight the flexibility of the OMAP platform's multi-core architecture to deliver high-performance multimedia and sophisticated user interfaces (UI) on the Android platform.

Kinda cool **** huh
Is it true that Qualcomm's dual-core CPU's will be based on the older ARM Cortex-A8 architecture set instead of the modern Cortex-A9 which is being used by Apple's A5 Chip and Nvidia'S Tegra 2 ?

The hardware benchmarks on the dual-core MSM8x60 1.2 Ghz chip used by HTC Pyramid (Sensation,Doubleshot) and the Evo-3D do not look pretty good.

Need a bit of clarification on this issue why they didn't choose the Cortex-A9 path.
Ok so I just read this report from Qualcomm explaining this issue:
http://www.qualcomm.de/documents/files/linley-report-dual-core-snapdragon.pdf
Apparently their architecture set is compatible with ARM's instruction architecture set and they claim its better than the A9.
"The superscalar CPU uses a 13-stage pipeline to generate faster clock speeds than competing products can achieve using ARM’s Cortex-A8 or Cortex-A9"
Having said that still not sure why the hardware benchmarks are not near the Cortex-A9 dual-core processors.
Adreno-220 is pretty good though compared to other GPU's.

Because bechmarks are meaningless and HTC have yet to put the work into fiddling them yet!
Quamcomm has been claiming that their design is better than ARM's Cortex A8 before but other than few special occasions, they are mostly equal at the same clock speed. Since MSM8x60 is also based on the identical cores, I don't see how it could be better than Cortex A9. In fact, Qualcomm is working on their own "equivalent to A9" version right now.
FYI, # of pipelines don't tell the whole story about the speed of CPUs. If not implemented well, it will simply cause longer stall delays. We have seen this in the old Pentium 4 architectures.
I think the 128bit fpu makes scorpion equivalent to a9 in floating points calculation

Finally, it's the first hard macro to feature the ARMv7-based Cortex-A15 'Eagle' IP. Unlike ARM's previous chips, the Cortex-A15 boasts a wealth of impressive functionality which makes it suitable for use outside the traditional embedded and mobile markets. Support for greater than 4GB of RAM and hardware virtualisation technologies indicates ARM's desire to attack the microserver and cloud computing markets, although at present the chip is still a 32-bit part - albeit one with 48-bit memory addressing.
The particular design announced by ARM ahead of its formal unveiling at the Cool Chips conference today boasts a 2GHz clock speed, a pair of 32KB L1 caches - shared between two cores - and a single shared 2MB L2 cache, 224 interrupts, six power domains, and support for the AMBA protocol for on-chip interconnections in multi-processor implementations.

This looks delicious!
about time to sell desktops and just buy a docking station for phone to plug into keyboard, screen.
ayi!!
Hello want to change my aunt and I am in big trouble
My choices are an Android device based on MTK 8127A from ATOTO but that come with 2 GB of RAM or a regular one based on PX 5 which come with 4 GB of RAM.
I understand that the MTK car goes devices are a little bit rare
So what to choose:
ATOTO with a MTK PROCESSOR and 2 GB of RAM, pretty good support and rom updates or a PX 5 ?
Which is faster and more stable?
Thank you

From what i have heard, MediaTek has better reputation than Rockchip. Which one is more stable / faster depends on how the SoC is integrated into the platform, how the Software Governers control the clock rate of the SoC. So this is difficult to answer strictly based on the SoC chip itself.
SoC Chip: MTK 8127A
Soc-based Quad-core 1.5Ghz Cortex A7 CPU
GPU ARM Mali-450 MP4 .
System Version: ATOTO AICE OS 9.4, which is developed & customized based on Android 6.0 Marshmallow OS;

but there are also :
PX6 ! devices (but it's news no more info a this moment) :
Android 8,1
CPUX6 RK3399
2 Core cortex A72 2ghz
4 Core Cortex A53 1.5ghz
RAM: SAMSUNG DDR3 4 GB
https://forum.xda-developers.com/an...-android-unit-cortex-a72-four-cortex-t3847427
And A72 Core is a lot better than A53, and A53 is a little bit better than the very old Cortex A7
I agree with @mum1989 that A72 and A53 CPU cores have much better specifications than the A7. If the applications you run on the head unit can take advantage of the ARMv8 instruction set or if the workload can be distributed across the cores, then PX6/PX6 SoC may well perform better than MTK8127A. On the other hand, in my day-to-day use of ATOTO A6 Pro which uses MTK8127A, I have never observed it to be slow or stutter or otherwise show signs that older A72 Core was limiting the end-user experience.
