Re: Maemo 6 / Harmattan on N900?
 

You can't really compare a 1Ghz snapdragon to a 600Mhz Arm A8 using clock speed alone, they are completely different processors and those numbers don't really mean much of anything unless you compare them to processors of the same family.
If you look at Android on the Nexus One and Maemo on the n900 you would be hard pressed to find a performance difference, because the major difference is the operating system.
Also we already know from the M6 slideshow that the next device will be built on the same hardware platform, OMAP3, OpenGL ES, etc. It also specifies that multitouch will be available for capacitive touchscreen devices. indicating that it will also still support resistive touchscreen devices (Why wouldn't it?). This means the is no reason to assume that Nokia would need to maintain two maemo for two architectures.

Re: Maemo 6 / Harmattan on N900?
 

Ajflex: Read my post again. I wasn't flaiming. I love the openess of Maemo but still this is a device i will use for at least 3 years. I will not use the same OS for 3 years. It is great that Maemo 6 will come to the N900. That might make it worth it.. but i do not think it is enough.

Capacitive or resisitive is nothing i care about and i hate Apple. Where did you se me write about that?

Re: Maemo 6 / Harmattan on N900?
 

Thanks! You read and understod what i was asking.

So you meant the snapdragon can be compaired with Arm A8 in speed? I have not tried to compair them before but now i might do so. If what you say is true. It would be wonderful.

Do you know the differens in bus speed of the two systems?

My fear though is that 600Mhz is little in the long run. It might be okey for the Maemo5 and 6 but what about the future?

If i get a device with 1000Mhz i will increase my chance of using the latest and best. If the updates of Maemo stop after version 6 i will need to try other OS's like Ubuntu (Arm) and here 600Mhz could be to slow. I know fennec is under development and will get better. The browser will be my most used device. I will get Java and Flash support.

This things need power.

Re: Maemo 6 / Harmattan on N900?
 

What I am saying is that a 600mhz Arm processor can be just as fast as a 1000mhz snapdragon processor depending on what it is doing. Honestly though what happens after Maemo 6? I think that if you are looking to buy a phone that will still be top line after 3 or 4 years down the road, you will be engaging in an exercise in futility. There is always something better on the horizon in this industry.

There is NO phone that exists right now that will run a desktop linux distro like ubuntu at what most would consider a reasonable speed.

AlMehdi no offence

Nokia over all its my thing

Re: Maemo 6 / Harmattan on N900?
 

look carefully that the cortex arm 8a have fastest cache 1 mb
that is than snapdragon have cache 256 kb not as fast as the cortex

Re: Maemo 6 / Harmattan on N900?
 

the arm cortex a8 is more powerful than the snapdragon.
and much much more feature has you can see

Re: Maemo 6 / Harmattan on N900?
 

Why are you comparing here the Prozessors?

The most of the time is the N900 running at 250MHz, not 600MHz... don't think about Prozessor speed. Think about the Battery!

Re: Maemo 6 / Harmattan on N900?
 

This is a user-perception thing. Battery parameters don't sell devices, GHz is much better from a marketing perspective. You would have thought since desktop processors made clock speed far less relevant people would would not buy into the same selling pitch again. Apparently they still do :S

Re: Maemo 6 / Harmattan on N900?
 

Thanks guys! This is what a community should be. This is why i now have ordered a N900. I have peaked at the droid community and could not find much. That might change.. anyway you are the best!

Now i just need to figure out or find an OS that just run the core phone functions and dual boot with Maemo. So i can save battery. :)

That is might be litte ot and should be discussed in another topic.
