    ARM versus the Intel Atom -

    We are watching closely the move of ARM into the netbook arena - is anyone familiar with the advantages of the ARM processors versus Intel's Atom -can the Atom really compete with ARM?


    HP is now considering using ARM in its netbooks.

    ARM processors do not run Windows so the question really is can ARM compete with Atom.

    False, they run windows CE (as well as many distros of linux).

    Most operating systems compiled to run on ARM processors are real-time operating systems, which don't operate a conventional event loop. This is great for applications such as robots where you have certain code that needs to be run at a certain time, and can NOT be late, however this is not so good for a general use operating system which has no real use for real-time support.

    The ARM does however use significantly less power (wattage) for the same amount of processing. Many smart phones run an ARM processor, as well as GPS units (My personal GPS has Windows CE + StrongArm 200mhz cpu). I don't think ARM processors will take over the netbook market, at least not until there is a version of windows that feels like XP, yet runs on ARM (XP Embedded?). People just aren't looking for something they have to administer to run such as linux. They want ease of use, and familiarity.

    Just my 2 cents.

    there is alot of 7 inch touchscreen with arm processor on ebay, i guess they use them for industrial equipments. if they are things that i imagine, we can have both the touchscreen and computer in single place, and not troubling by the cables. it will be tidy option

    Don't BMW Nav systems run on a real time OS? Thought I remembered reading that somewhere


    Yea malcom summed it up pretty well. The main thing carPC users would be concerned with is that not only the operating system but any application that ran on it would need to be specially compiled for the arm processor. Even though linux could be compiled to run on ARM processors, all of the software would need to be native Linux apps compiled for an arm processor or run in a virtual machine. Wine translation wouldn't work.

    Intel still can't hold a candle to arm on low-power devices. When was the last time you heard of a mobile phone with an intel chip in it? For many years, if if your mobile phone didn't say "Motorola" on the front, there were pretty good odds that ARM designed it. There *still* pretty good odds that ARM designed the chips are running most of the things in your house that isn't an outright "computer".

    Nowadays ARM have been rapidly catching up with intel on crunching power, too. As others have pointed out, regular windows doesn't run on ARM. That's the only "downside" to ARM chip. I put downside in quotes because, at least for low power systems [netbooks], the truth of the matter is that linux is a far more appropriate system. Your games, and MS Office, run on Windows. If you're buying a netbook, and you want your high-graphics-quality games to run, you're in for a major disappointment.

    Write down a shopping list of the things you need out of a modern netbook; most of the time you'll find that Linux meets your needs. Honestly, it's no greater a learning curve than moving from XP to Win7. [Heh, heh. Vista. heh heh]


    Fun fact: ARM design chips, they don't mass manufacture them [at least, they didn't until very recently. I learned that while interviewing there for a job, many moons ago].

    PS Loooove my SheevaPlug. It has a 1.2GHz ARM chip in it, which handles all my OBDII needs, and a bunch besides, with absolute ease.

    I thought winelib runs on ARM, no? You could still build and link your windows programs on Linux using it. I mean, I hate wine as much as the next guy, but it's not totally out of the question

    Winelib would...but that requires recompilation. Wine itself doesn't, so for things like commercial GPS software....your outta luck.

    ARM based netbooks will be targeted at lower prices than intel. ARM chips are usually less power hungry than the Atoms. Sub-$200 Linux based netbook with great battery life.

    Putting windows on the thing would be pointless. The reason why people buy windows based netbooks are because either they are just generally more comfortable with windows (as chunky said, that comfort is disrupted when upgrading from xp to 7 anyway), OR they have some app that they already own that they want to use on their netbook: ie, photoshop, msOffice, Centrafuse, etc. Of course, none of those apps are going to run on a Windows CE device. On Linux however, every open source app that runs on your desktop, will run on the ARM device. The end-user running Linux doesn't even care what his CPU arch is.

    Furthermore, windows CE adds cost to the device, which puts them in the atom price range.
