ARM Powered OLPC XO-1.75 Laptop Is Faster Than X86

Charbax writes "Not only is power consumption halved to less than two Watts and price of the motherboard reduced, the performance of the next generation OLPC Laptop is actually better for running full Fedora Linux compared to x86. Here's a video interviewing OLPC's CTO, Edward J. McNierney, where he explains how and why OLPC's world class engineers are making this change of CPU architecture. If OLPC XO-1 threatened Intel enough to start the netbook market and has reached two million poor kids in third-world countries thus far, XO-1.75 may help start the ARM-powered Linux laptop market. Do you think Fedora/Sugar will do, or should OLPC attract Chrome OS and Android solutions for education to get faster help from the big boys of Silicon Valley in bringing Linux software successfully to the next billion PC/laptop users?"

    Anyone else notice that they are building an Arm powered ARM powered computer? Now requiring only half as many cranks.

    They cost an ARM AMD a leg!

    ... a full blown Linux distribution that does not require children to learn a new UI...

    You know, I think any computer UI is likely to be a new one for many of the children they're targetting. They've got a rare chance to design an interface for people who don't already have expectations of how to use a computer. I know I'd take that opportunity to see if I could work out a better model.

  4. Um, faster than...an 8 year old x86 by AcidPenguin9873 · · Score: 4, Informative

    The original XO-1 uses an AMD Geode LX 800, which was released in 2002/2003 or thereabouts. This latest XO-1.75 uses a Marvell Armada 610, and the marketing material I'm looking at from Marvell has a copyright of 2010 on it. The CPU in there is a Marvell Sheeva which the earliest reference I can find is from 2008, but that's not even a fair date because that's when they announced it, not shipped it.

    So yes, this processor is faster than an 8-year-old AMD Geode. I would like to see power/performance tradeoffs vs. today's Atom and AMD Fusion stuff before everyone goes nuts about how ARM is faster than x86 for half the power.

      Atom is a power hungry son of a bitch compared to Arm gear. The lowest power PineView based one is at 6.5 Watts and that is the CPU alone, the Arm stuff is all SoC. The whole SoC power budget is going to be less than that.

      Once you start to value power consumption above all else Arm really starts to make sense. When you can plug in your laptop every couple hours well less so.

    The $100 has always been target that can only be reached once more than 6 million units are mass manufactured, that was always the original idea. Intel tactics though, it has been proven in official state letters, successfully blocked OLPC from reaching countries like Nigeria, China, India, etc. But even though they "only" sold 2 million laptops to children in some of the poorest places in the world, you can find plenty videos online http://olpc.tv/ , see how the kids and teachers are using those daily, it's a huge success. I mean comon, OLPC may have deeply changed the lives of 2 million families in more or less very poor third world countries. Sure enough, it'd be better they reached 2 billion kids by now, by they I mean OLPC or anyone else in the industry. It's all about lowering cost and lowering power consumption of laptops and also bringing internet everywhere.

  6. Don't bother with Android by rickb928 · · Score: 5, Insightful

    It doesn't solve a problem that XO has. Linux fits very well.

    Windows on ARM doesn't solve any problem XO has either, and potentially causes some, like licensing and lock-in. between you and me, if we're gonna start kids off with computers in the Third World, Linux makes WAY more sense than Windows. Even more than Android. Crome is not ready, and the cloud may not be Third-World-Friendly for a long time. try not to rely on resources that are either not available, cost more than food, or can be taken away by other nations, or even their own.

    If ever there was a project that leverages the maximum potential for freedom via the Internet, this is it. Really, give the kids someething they can work with and watch out. Somethings wonderful will happen.

  7. Why android over standard Linux? by chipwich · · Score: 4, Interesting

    As I've watched Android dominate the tablet market, I'm bothered by the fact that these devices do not give root access without "jailbreaking". Isn't Android a major step toward the very scary world of "Trusted Computing"? That is, the hardware manufacturer, government, or whoever else has power can deny the ability for a user to run a program (or all programs!) at whim. Right out of the box, the user is denied permission to use their hardware in the way that they see fit.

    I feel much more comfortable with a full Linux distro that empowers its users, rather than makes them comfortable with someone else holding the keys to their machine. Besided, android hardly seems compatible with the "open" goals of OLPC. A full distro would take advantage of a real JVM and a much richer software eco-structure instead.
