    Phoronix: NVIDIA Publishes Their Next-Gen Tegra 4 Code

    NVIDIA released Linux kernel patches this morning for supporting their next-gen "Tegra 4" SoC under Linux. A few details were revealed within the code commits...

    Where is the 72 gpu core number from? I've heard a lot of completely different statistics on the Tegra 4 gpu (the architecture its based on, the clock rate, the core count, etc) and 72 is the highest number I've heard yet. Seems like quite the jump from the 12 cores of Tegra 3 (though if it is based off Kepler, we should expect big core numbers).

    GPU "core" numbers == Bogomips

    But they get bigger and bigger so they are perfect fit for PR materials.

    Glad to see Nvidia is working on open source drivers for Tegra 4. Kernel 3.9 is a little later than I expected it, and it might not even be fully done for that, but sounds pretty good overall.

    Everyone here seems to have missed something really important - VP8 encoding/decoding support. A patent-free audio/video format with actual hardware acceleration. It sounds like Google has big plans for WebM and Android - it may be that more Youtube videos will be converted to WebM, and we can actually play most videos in Firefox/Chromium/other browsers without having to use Flash.

    In fact, most of youtube videos are already converted. Yet for some reason not all videos are directly playable so far. If they do not play with "watch?v=video_id" try youtube.com/embed/video_id and see: in fact they have webm copy on their servers. And it plays. There are some rare exceptions but 90+% videos are available this way already. And yeah, there are many SoC vendors announced hardware VP8 support. It's fairly predictable granted that google gives away ip block free of any royalties, etc.

    ...but I failed to understand how it related to opensource AMD drivers
