Now they are cheating on their processor clockspeeds: http://www.xbitlabs.com/news/cpu/dis...igh_Loads.html

No announcement yet.
Another reason for me not to buy AMD anymore

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.

I think it's a case of consumer vs server workload. Consumer cpus (or gpus, see furmark) are not assumed to run at 100% for hours, so they're not thermally specced to withstand that, so that marketing can claim higher default numbers.
Server cpus typically are specced for such workloads.
Whether this is false advertising for consumer items is up for debate.

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.

I don't think it is a good hardware design when the cpu consumes by default too much power that it has to lower clockspeeds on certain loads. Intel has power saving cpus as well, there the default clock is lower by default - the rest is done using turbo steps (for i5+). Turbo boost has of course a power usage limit (can be set in firmware for oc). So basically AMD should rebrand the cpus and use a lower default and more turbo steps. A cpu that does not run a specified speed under all loads is a joke.
