how do the mobile phone CPUs compare to desktop PC CPUs

[AndroidSPCS]

It's been a long time since I have delved into / kept up with processors, so I'm curious - how do the top mobile CPUs (like the snapdragon 1GHz etc) compare to desktop CPUs (like the i3, i5, i7)??

Can anyone explain how they compare in speeds, processing power, etc in layman's terms?

I know that for speeds, they are at least half the speed of most desktop CPUs. Not really sure how they compare in computing power. And I know Intel is working on getting a low-powered version of the Atom CPU into cell phones, that should be interesting.

I sure hope they do b/c that thing will last quite a while (battery power wise).

Well for sarters there are no 64 bit cpu's (that i know of) for mobile cellphones as of now... only 32 bit for now...

And obviously no fans hahahaha lol sorry i am being stupid...

Now I might finally post in right thread!

I can't go into this in depth, think you need some of the more noteworthy tech savvies in here then for that task. What I can say is that phone CPU's are really going forward in a massive speed, but same applies for computers as well. I'm not gonna take this statement I make now for granted, but I don't think phones got double processors just yet or nearby quad processors.

So it still some time before you catch up there, but on the good news. As it's now, phones are getting more and more love so it shouldn't take too long time before mobile technology will get a boost jump in processors.

Correct me if I'm wrong, all of these statements are just assuming. I rather have someone with the insights and knowledge to talk about this, rather then me.

Hey Aiyan!!

Yes you are very correct... the massive explosion and future potential for smartphones is deffinately there / already here!

But what i believe is that Photonics (Optical light computers) will be the future of all computers... they use photons instead of electrons.... this means a crap load less heat.....and yes it is very experimental at the moment...and very expensive...sadly...

One of the biggest problem with computers is temperature...or heat it generates. This is almost completely taken away with Photonics... cause light generates alot less heat than electricty...

Here:

The Affect of Heat On CPUs and Computer Systems

and Photonic Computers is here on Wikipedia:

Optical computing - Wikipedia, the free encyclopedia

and the advantages of Photonics:

5. Advantages and Disadvantages of Optical Computers

Hmm yes i hope we will see this happen in our life times i hope at least....you see the speed of light is WAY faster than the speed of electricity....here:

The Photonic Computer

I wud love to see this happen in the corporate world and become commercially available... we will have to wait and see...

Granted, my Eris is a pretty old device in the Android world. But it is outperformed by a Pentium II in terms of raw power. Now there are some things it can do, that the Pentium II cannot, such as play compressed MP4 video. However, many newer phones are far more powerful.

Comparisons (using the Linpack floating point calculation benchmark):

HTC Droid Eris - Android 2.2 (2009): 4.7 MFLOPS - 17.78 seconds
Pentium II - Windows 2000 (1998): 11.47 MFLOPS - 7.29 seconds
Pentium 4 - Windows 7 (2005): 185.88 MFLOPS - 0.45 seconds
Core 2 Duo - Windows 7 (2006): 432.13 MFLOPS - 0.19 seconds

That's how my phone ranks among my PC's. However, the Eris being a ARMv6 phone, it has no hardware floating point processor, so it has to crunch these numbers through software which is much slower.

It's hard to know for sure, but let's just say that the core iSeries is several times faster than even the ARM 15.

Remember that desktop CPUs are real workhorses with massive fans and tons of heat that require a PSU. Don't let the MHz ghz numbers of the ARM processors fool you. Current ARM processors are barely as fast as old pentium CPUs.

Just ran that on my Droid X- Android 2.1: 7.638 MFLOPS - 10.98 seconds

Does anyone know what the instructions per clock on these phone's run?

Are we looking at a single instruction per clock? 2 instructions per clock?

I know the intel cpu's dating back to my brothers q6600 and even before then all do 4..

AMD does 2.

Create's some huge differences in benchmarks.. (Still like amd though..)

I have wondered about this quite a bit but, most people ignore my questions x.x

He hehe

I am not ignoring this question

Hmm i think so i dunno hahaha lol

Tried looking up what your asking, and all I could pull up was information on IPS (instructions per second).

lol I've had asked about it on other forums and received the reply "why are you comparing phone processors to desktop processors?"

People just don't get that I have an unending thirst for knowledge in regards to things related to computers >.>;

Now I want to OC a phone ..

Curse my horrible addiction.. My desktop isn't going much higher.. so I gotta push a phone now x.x
