    Server cpus typically are specced for such workloads.

    Whether this is false advertising for consumer items is up for debate.
    My consumer Phenom II X6 (125W version) can run under 100% load for hours without downclocking itself, the same is true for my laptop's Athlon QL-66 and was true for my former Core 2 Quads (Q6600 and Q9550) and Athlon X2 5200+ and any CPU I used before that.
    I can't see any reason why I should expect it to be different with newer CPUs, consumer or not. If a CPU is advertised as 3.8GHz model it has to run 3.8GHz, not 3.4GHz.

    Of course those test shouldn't be done at 50?C ambient temperature, and I seriously doubt they were. In that case the Intel APUs should have the same problem, which they hadn't.

    The thermal specs are given for a specific ambient temperature. Running a processor at it's advertised normal speed in winter in northern Scotland and mid-summer in southern Spain will likely result in very different temperatures for the same workload.

    Hm, I'm not a native english speaker but the english in the article is rather poor.

    The quote at the end does have an opening quotation mark but not a closing one. They also don't say where they got that quote from. Googling it only shows http://www.hitechreview.com/it-produ...er-load/42259/ and http://news.softpedia.com/news/AMD-T...e-342157.shtml referencing that article.

    Come on, even phoronix is better journalism.

    Phoronix may even have measured the actual performance loss.
