Comparison of CPU's

Hi
I wanted to know what is the most stable CPU on a Pocet PC right now and why, what makes a processor better than the next ? are Intel processors better than samsung, TI, Freescale ??
what are the categories of all these processors ?
and on a pricing level which processors are value for money ?
which are expensive for something and which are expensive for nothing ?
this has been working on my mind for some time to analyse all the processors and identify the truth behind Pocket PC CPU's
can anyone please help to answer these questions.
regards

The differences are very small, unlike with, say, 486 or Pentium clones 10-12 years ago. That is, there aren't known problems with Samsung / TI CPU's and there aren't "clearly the best" CPU's.

hi
what do you think about Freescale CPU ?
and when it comes to CPU, do you think that mayb certain types are more stable than others ?
Stability = litlle or no freezing up, compatibilty, works well with WM OS, aplications funtioanlity, and just general operation you no that sense that you can rely on the product to function properly.

Dunno much about the practical stability & compatibility issues of the new Freescale CPU, it's so new to the market (and iDo devices are so few).
In general, I don't think any current (again, I don't speak for Freescale) CPU's have any stability or other issues. Samsung CPU's, in the past (see for example the flash ROM problems of the iPAQ 1930 / 1940) had some problems; hope they're fixed now.

hi
is there any way to benchmark the CPU's ? is there any software that i can use. i would like to conduct a test to make a comparison.
about the freescale, any reviews about this CPU ?

Spb Benchmark, for example. However, benchmark results are pretty useless. For example, the 195 MHz TI CPU's are MUCH better than what one would think based on the benchmark results
about the freescale, any reviews about this CPU ?

Googled around; haven't found much.

I will keep searching for more details on freescale.
Do you think there is mayb factory benchmark programs then we can mayb get accurate results ?

In general, I wouldn't depend on benchmark results. For example, the TI CPU-based devices are far faster than one would think based on the benchmark results.

I have read about Processors from Intel called Monahans, i believe it is the latest CPU.
Have you worked with a handheld device running this CPU ?
could you give us some info on the Manahans and Boulverde ?

try this one.... I got it from buzz website....

Generally, TI and Samsung processors usually are more performant than Intel with the same MHz rate (iirc about 20%).
However, processor performance is not everything. E.g. the memory access is very different on WM5 devices. Or graphic performance.
And don't forget many PPC applications are quite spartanic - you don't need lots of CPU power to add a new contact or write a document in that better notepad called "Word mobile". Memory (card) access is more interesting there. But you'll probably notice a difference e.g. in navigation, games, or multimedia.

TI OMAP850 vs INTEL PXA27X

This is a question that maybe a lot of members have.
As we known OMAP850 has 2 cores 200 Mhz for GSM and 200 Mhz for WM App
And that is great ... But what happend with INTEL Processors?
I was looking info on the web about PXA27X and how manage the Mhz when WM have app running and have a incoming call.
Example. If a INTEL PXA27X has 400 Mhz how much Mhz will gone in GSM.
Or INTEL PXA27X has another core for GSM? Like OMAP850?
Or when has a incomming call the 400Mhz goes to 300Mhz or less ?
I got a TEK S200 and I ask this because I wanna buy another PDA, maybe HTC, ETEN or HP and i have this doubt.

I'm not really sure what you mean - do you mean if the CPU has enough computation power to execute other tasks while the GSM is active?
If you have followed my articles (most importantly, the ones concerning recording phone calls), you already know the answer: yes, the CPU has the power to execute almost anything else. I haven't made exact CPU usage benchmarks (with acbTaskMan), but I don't think the CPU usage of the GSM module is higher than, say, 20% on a 416 MHz XScale.

it all depends on yr usage. and what u do with yr pda phone.
omap is good for battery life, if u just do appointment & task, simple mp3 leisure yes its for u (dun think abt video)
samsung chip, for 3g, good for almost all but cant support better playback for dvd quality example MOV files on tcpmp
intel chip, 416mhz is good for everything, skype, youtube, mov dvd quality video play back. but battery life sucks...
as HTC use more of TI OMAP on non 3g or SAMSUNG chip for 3g device.
while O2 Asia use INTEL chip for all the devices but have customize the chip so that u can choose between PERFORMANCE or BATTERY LIFE. appears in XDA IIi (htc/ppc2003), STEALTH (gigabyte/wm5), Zinc (asus/wm5/6), Atom Life (quanta/wm5/6), Flame (arima/wm5). so far only o2/asus/gigabyte have such feature for their pda phone.
so if you like multifunction/tasking(skype/msn/wifi/internet radio/surfing). get a good device, like ATOM LIFE

oh one more, XDA 1 is using INTEL 150mhz if i recall haha
so if u like intel so much & u want that speed, find wallaby haha

Also add the new Qualcomm MSM7200 chipset. It seems hardware manufacturers are switching to it and ditch at least the not very multimedia-friendly Samsung. (I bet something similar will alos happen to XScale, unless they manage to radically reduce their power consumption.)

f-ing idiots should just keep their mouths shut. It's 208MHz, you moron. And the guy is asking about processor division of resources, not saying he wants Intel. GOT THAT? or do you need further translation?

raymondu999: I'm gonna ask you to control yourself next time. Such attitude will not be tolerated here. Thank you.

"while O2 Asia use INTEL chip for all the devices "
o2 is a phone company they dont make phones the oem phones from other companys

afaik the omap850 is not a real dual-core cpu, because both cores are not the same. one is used for normal apps and the OS and a simpler one takes care of the GSM part.

So... OMAP850 is a Simple Processor for GSM + 200 Mhz Processor for apps
Then my doubt is how Intel manage this, if a device has a spec of processor 416mhz , this 416mhz are for GSM and Apps.
I read in some posts that Intel processors has troubles to manage GSM-APPS-WIFI etc.

intel dont magede gsm and wifi
it's handled by 3th party chips i believe
it would simply see them as IO devices

[Q] [ASK]armv7

Hi all, I have read many articles that say to be able to use adobe flash player 10.1 you must have armv7 processor, I was wondering,
what's the difference between armv6 and armv7?
Is it possible to modify the armv6 based phone to be able to use that?
wht r phones that use armv7?
thx b4..

Hi and welcome
You can not change the processor, it would be like making your P4 a core i5, I think the difference is in the architecture and the instructions.
However you can check if your phone supports it or not, devices with qualcomm snapdragon should support flash, you can find a comprehensive list of device specs here - pdadb.net

i see, so just the phone with qualcomm snapdragon that will support flash right?
is there any chance the other phone with different processor could do the same?
Because if not, it will affect the price of all entry level android phone in the future and it means we have to buy an expensive android phone to just be able to use flash

The samsungs with the ~1 Ghz CPU will probably support it, as well as tegra and tiomap, just check the particular device you want

sensation performance / aSMP info needed please

Hi,
i recently return my samsung (4th time) galaxy s2 becouse of various defects , i been looking at the sensation however i have a few questions , firstly for all its issues i like how fast and responsive the galaxay was however when i tryed the sensation i noticed its not as smooth as the galaxy or that much smoother then the desire hd.
One possible reason for this i noticed was that the sensation uses a asmp cpu , which seems a bit cheeky to me. I mean im buying a dual core phone so i would like both cores to work at the same time as opposed to one working then the second kicking in when the first is loaded. From what ive read ics should have better support for this setup , so i was curious does anyone think we will see that much of a difference bearing in mind the sensation is asmp.
I notice there`s a lot of talented devs from the desire development and hd which is encouraging so i was hoping to learn from various users how much of a performance increase there seeing in custom roms ie is the browser jerky like stock ??
Appreciate any / all feedback thank you

I'm interested in some more more info on this topic as well.....

Read up!
ok so aSMP doesn't really work in the method of core 0 gets loaded then core 1 kicks in, thats way off.
basically SMP cpus like Tegra and Samsung's both cores run at the same speed, so core 1 follows core 0. This doesn't mean that core 1 is actually processing anything. In most cases due to gingerbread the phone is still mainly running on one core unless the app supports multicore.
aSMP allows the cores to run completely independent. This is great for battery life. Core 0 can do things like play games and stuff at full speed while core 1 handles background data.
so playing angry birds while syncing photos on flickr:
core 0 could be running at full 1.5Ghz
core 1 could be running at 500Mhz just do handle the syncing
This is basically the idea. We will get better support with ICS for full and proper support for multiple cores and the kernels will only get better as devs learn.

Hi,
Thank you for you detailed reply ive been following the thread you posted which is what led me to posting question here , i obviously misunderstood what was being said. That being said im no expert but if i buy a dual core phone id rather have both cores committed to one task like pc ... this is one of the things thats making me hold back on sensation. Althougth its a great phone with great ui and fantastic potential with future updates and dev support to the touch at present the galaxy s2 just seems smoother with the way its doing thing.
As i say thou im not expert i can appreciate theres other factor to take into account such as kernal etc, im just going with hands on usage and trying to evaluate the future potential for both devices before making a decision to which i should choose

The sensation's CPU works in a much more power efficient way, while still offering the speed of any other dual core CPU. It allows different clock speeds for different cores so applications using only a single core will be able to clock it differently to those using the other in the background. Computers, especially laptops work in a similar way, as there is a need for power efficiency. Realistically the Galaxy SII runs smoother due to it running a much less resource hungry skin on top of android, but both the CPU of the sensation and the Galaxy SII are both of a similar calibre, so it is very difficult to say which is better.

again thanks for the reply , defintly understand how this asmp buisness works more now which has given me some stuff to think about

Neither architecture, SMP or aSMP, will commit both cores to one task unless the app is multithreaded and it currently needs the use of both cores. This is the same way that multicore pc's operate. That's why when quad core CPU's first came out people said that they didn't feel any faster than comparable dual core chips - most existing apps at that time were written for single or dual threaded use so the third and fourth cores largely sat unused. The pc doesn't just force the use of the extra cores just because they are there (regardless of how they scale, aSMP or SMP).

Also the new firmware has made it smoother due to extra optimisations. Web browser is not as good as the galaxy S 2 due that being GPU accelerated. Power wise the Sensation you will get somewhat more out of your battery life wise.

If you look at my thread and see the post:
MSM8x60:
Adreno 220 GPU
2x Cortex A8 Based Cores
512KB L2 Cache
45nm
upto 333Mhz LPDDR2
Exynos 4210:
Mali 400 GPU
2x Cortex A9 Based Cores
1MB L2 Cache
45nm
support for LPDDR2/DDR3
Tegra 2:
ULP Geforce GPU
2x Cortex A9 Based Cores
1MB L2 Cache
40nm
support for 600Mhz LPDDR2
So the biggest thing is is that the Exynos is based on a new core micro-arch then the Snapdragon 2, also it has the ability to support DDR3 memory. To go into more detail about ARM Cortex.
Items that A8 and A9 have in common:
Jazelle RCT for JIT Compilation
Neon SIMD Instruction Set (Optional)
Thumb2 Instruction set
VFPv3 Floating Point Unit (Optional)
Cortex A8:
Superscalar Dual-Issue Micro-Arch
2.0 DMIPS/Mhz
Cortex A9:
Out-Of-Order Superscalar Micro-Arch
2.5 DMIPS/Mhz
Jazelle DBX for Java Execution
Dual-Core Processing Built In
The SGSII has a new generation architecture as so does the Tegra

This thread is iteresting. I want to continue that.
my cpu0 and cpu1 arrive at 1,7 ghz. so cpu1 doesnt arrive up to 500 mhz

[Q] Is swapping out Snapdragon processors possible?

I did post this under Nexus 5 Q/A, but I realized this probably applies to all Android devices, not just the one I have. So sorry for dual-topic, but I feel this kind of belongs here more.
With the Nexus 6 announced, I was quite disappointed, as I was expecting Google to release an updated version of Nexus 5, just like they did with Nexus 7 back in 2013. I'm not a fan of phablets, and 6 inches seems too big for a phone, while Nexus 5 sure hit that sweet spot.
So I had this idea - would it be possible to replace the old existing Snapdragon processors with newer versions? 801? 805? What about the new 808/810 models? Problems that come to my mind are:
Do the newer processors have the same pin layout as the 800 version? I managed to find information that the 801 is, but I'd like to know about 805 or even 808/810.
Do different Snapdragon 8** series processors use the same instruction-set? If not, are the newer versions backwards-compatible with old versions, like for example Intel's x86?
Would the old chipset be able to take advantage of a faster processor? I know ROMs with custom kernels allow overclocking up to 3 GHz, although that's just stupid. With a 805/808/810 though... Would it be as simple as getting for exapmle CyanogenMod, "overclocking" the 805 to 2.7 GHz (what it's actually rated at), and that would be the end of the story? Or am I missing something?
How hard would it be physically to replace the processor? I imagine a skilled engineer with a soldering station would be able to do the job, or are the connections so small that it's practically impossible to do by hand?
How does one obtain a stand-alone Snapdragon processor? I can't seem to find any on Amazon. Do they even sell retail, like Intel/AMD? If not, how do I get hold of one?
What else am I missing? How feasable is this idea really?

Short answer. No.
Unlike the "Can I upgrade my phones memory?" question, this one is a much more definitive no.

From what I hear, the 810 will be the last 32-Bit Snapdragon SoC.
Meaning, even if you could (I highly doubt you can) your only improvement would be less than 0.5gHZ.
So not really worth the risk.
