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

QUALCOMM 7200 400Mhz VS. XScale PXA270 520Mhz

Hi @ll..
i will buy the new HTC TyTN II in the next 2 weeks. This one has an Qualcomm 7200 Processor with a speed of 400 Mhz.
Today i found the XDA Flame (cause of the GeForce 5500 ;-) ) and found out, that its the Toshiba G900 with a XScale PXA270 with 520 Mhz.
But this Processor is older than the one of Qualcomm, isn´t it?
So my question:
is the qualcomm a better processor than XScale? Is it also faster? (i know.. 520Mhz vs 400Mhz.. i mean this, like on PCs.. i.e. a Pentium 3 with 300 Mhz is also faster than Pentium 2 with 300 Mhz)
thanxx

HTC TyTN processor vs. XDA Flame processor
I think that because the flame has the GoForce 5500 GPU in it, it means that the main processor doesn't have to worry with graphics - leaving it free to process other stuff. So it's more powerful then. I've got one, and it's pretty quick.

However, don't forget that VERY FEW OpenGL ES games / emus / demos (all desginedearlier for the 2700G) run on the Flame.

twice it has worked, not because it fails.
Any idea?

I have used XDA Life with Intel 620mhz & then I used TyTn II, I feel the TyTn II is much better then Life. it has no problem with what so ever while running apps. my vote goes to tytn II.

[Q] Dual-core necessary?

Are there really that many things out there that can take advantage of a dual-core cpu? It seems to me that a decent cpu/gpu can go really far, but idk.

I'd imagine it'd be similar to a desktop. It will initially help with general smoothness of the user experience. Eventually apps will catch up with the hardware and be multithreaded.

i can see the use for dual core phones
but quad core or penta core phones is simply too much

More cores = better efficiency = longer battery life. It's not all about performance.

On any os aside from android, no.

Currently no. Seeing as software has yet to catch up to hardware, and really never has in this technological era. >.>
So with such info, one can make the statement to say the latest hardware is never needed, atleast in its time. Sooo... lets all throw away our core i7's, 1080p displays, Radeon HD 6990, and go back to the good ol' pentium 4 with integrated Intel graphics.

the new android os (ice cream sandwich) is supposed to support dual-core processors. If this does end up happening, it won't be long till there are apps such that do make use of the dual-core as well.

Yea! Try web browsing on a dual core. You'll never go back.

All depends on the software taking advantage of dual-core or not.
Similar scenario happened on desktop PC few years ago, and dual core cpu performed worse than similar clocked single core cpus when running non-optimized software. Took a period of time for the software to take up.

[Q] Dual-core clock queries?

This is a hardware question, I have a friend who owns a Desire HD, now he goes on and on about how Single core phones are just as powerful as Dual core phones because, and this is his theory, a Dual core phone that says it is clocked at 1 GHz actually has either core clocked at 500 MHz, whereas the core in a Single core phone is clocked at 1 Ghz flat.
This just honestly seems like a frankly rubbish argument that doesn't make much sense to me, however I want to know if he's right, is there any literature out there that proves either way. Is he right? Or is he just being a boner?

long story short, he is wrong. keep in mind dual core s different from dual processor. the processor of a dual core simply allows 2 instructions to be carried out at onece adding performance to programs that have lots going on at the same time, but is still the same otherwise. They seriously help with multitasking so on android they would really help .

Correct! It allows 2 different "threads" to be computed at the same time. Your friend isn't all wrong though. Any app has to fully support dual threading. If it doesn't you will see the same performance from a 1ghz dual core phone and a 1ghz single core. Also remember the architecture of the CPU is important. In many cases a 1ghz phone may perform better than a 1.2ghz phone.

Well, almost.
Dual core means there are two independent processing units on the same chip. The chip itself operates at 1gigahertz, and that generally applies to anything on that die.
so your friend is wrong, as both cores run at 1 gig, but a lot more factors relate to actual performance.
In most cases, single core will not perform as well as a dual core at the same speed. (assuming they are the same arch)

Some dishonest Chinese sellers will do things like this.
Some places you'll see dual core NEC EV2 based tablets as "1ghz" even though it's two ~500mhz cores.
Other places you'll see a single core device deceitfully advertised as "dual core" as it includes a GPU in addition to the CPU.
They'll then add the GPU and CPU frequencies together and sell a 1.1ghz device as 1.5ghz.
(And don't get me started about seeing "Cortex A10" in the specs)
So long as we're discussing legitimate specifications, your friend is wrong

The most important thing is.... To tell your friend he is totally true.. When he revises his theory somedays later, then listen to him.
Sent from my ME865 using XDA

It really depends on the apps that you are running. Gingerbread does not fully support dual core processors but the Android (linux) kernel does. So if the apps you are running are written to take advantage of the extra core, they will run faster on a dual core phone. Where it does help to have an extra core is multitasking, with a dual core phone you will be able to smoothly run more apps at one time. But if you benchmark an app that only utilizes one core on both a single core and a dual core phone, the results will not automatically favor the dual core phone.

[Q] What is the actual difference between ARM and desktop processors

Sorry if this question was already asked(i could not find it any where)
Sorry if this is in wrong place
so here is the question
I know that all android tablet&phones are built with ARM processors.But what is the difference between ARM and desktop processors
they come in single core, dual core, quad core, octal core (read:Samsung To Unveil 8-Core ARM Chip In February so they have a bit more power than the PC's in 2005's so why cant they run a full functional windows 8 or linux(android is based on linux) or win7 or winxp?
win xp need only 512 mb ram but now a days we have 2Gb ram Tablets why do they need android instead of it why cant they insall windows
OR
Is there a way to run windows in tablet (not by emulating)??

ARM is the architecture, different from x86/64, an OS not designed for an architecture cannot run on it...
This is as far as I understand why Ubuntu OS uses CM10 as base, instead of rewriting the whole OS from scratch.

Arm is something like proccesor designed only for small devices like mobiles..
It is at low level for now,later days it may reach to a good speed proccesor.
Since it is for small devices, it will not carry much load, as pc processor does..:thumbup:
