from the 8=4 dept.

In 2011 AMD released the Bulldozer architecture, with a somewhat untraditional implementation of the "multicore" technology. Now, 4 years later, they are sued for false advertising, fraud and other "criminal activities". From TFA:

In claiming that its new Bulldozer CPU had "8-cores," which means it can perform eight calculations simultaneously, AMD allegedly tricked consumers into buying its Bulldozer processors by overstating the number of cores contained in the chips. Dickey alleges the Bulldozer chips functionally have only four cores—not eight, as advertised.

    Yes, but most streaming stuff isn't transcoded from one format to the other every time someone requests a stream.
    You do it once, and save the file, then chuck what ever format they ask down the socket as fast as the requester can consume it.

    Admittedly, you still have a transcoding task just to arrive at a copy for each format. And maybe these processors do that just fine, and maybe they don't, I donno.

    No, you are mistaken. I've always had this sig.

    most streaming stuff isn't transcoded from one format to the other every time someone requests a stream.

    If someone is sending a live stream that has few simultaneous viewers, the server might end up serving the transcoded stream at each detail level to one viewer or at most a handful. Even apart from live streaming, I'm told some adaptive streaming platforms do a real-time transcode for a few seconds rather than waiting for the next keyframe to switch detail levels when the Internet connection's throughput changes or when the user fast-forwards or rewinds.

    Admittedly, you still have a transcoding task just to arrive at a copy for each format.

    Even apart from live streaming, uploaders on big video sharing sites such as Dailymotion and YouTube initiate so many transcoding tasks that I shudder to think of how many must be running at once.
