ARM Marches Onward

Obviously ARM is doing very well in embedded stuff and smart thingies but nVidia’s newest Tegra chip is mind-blowing. They tout it for mobile but demonstrate it doing video and games on huge monitors. Does that not spell desktop/notebook/gaming console? Yep! There’s a rumour that this will power the next iPad.

Given that one and two-cored chips are adequate for phones this is a tablet-and-more chip. I can see it in notebooks and desktops as well as tablets and gaming consoles.

  1. Lots of browsing can use multiple cores like playing Flash while loading pages and requesting multiple images in different processes. A browser would be silly to load one image and wait for it to be fully downloaded before requesting another. The web is a transactional medium with synchronization, not a single-headed hard drive. Whether the decoding of the image files is broken down into processes is a simple choice of the programmer. Why would a programmer prevent that when the hardware and the software can do it easily? Normally one core can handle tens or hundreds of processes. An OS like GNU/Linux can farm them out to cores automatically. Just ask the OS to start another process and it decides where to run it. If the overhead to start a process is excessive, just start a few and locally farm out images to each process. There’s no advantage to that on a single-core CPU but many CPUs have at least two cores these days.

    I believe what you actually see in the second video (the web browsing benchmark) is the power of WebKit, and not so much the power of quad-core.
    I very much doubt that one web browsing request is broken down into 4 chunks of processing such that it would be executed in parallel by all 4 cores. That would be so non-sensical, it would make my brain hurt.
