[xbitlabs] AMD A-Series “Trinity” APUs Can Drop Clock-Speed Under High-Loads.

Contemporary microprocessors from AMD and Intel can dynamically change their clock-speeds in order to reduce power consumption or improve performance. Still, there are certain clock-speeds that are declared to be default and at which the chips should operate most of the time in all applications. However, it looks like under certain conditions AMD’s latest microprocessors for desktops run at lower clock-speeds, which negatively affects performance.

It is interesting to noted that the frequency never drops when Turbo Core is disabled and the processor operates at 3.80GHz all the time.

Doesn't seem like a big deal, at first it simply sounded like it was thermally throttling but I guess it's more of a 'turbo' bug that over-reacts to a potential high temperature event.

I wonder why it was just announced shortly before Trinity's replacement by Richland, instead of last year in the summer?

Errr, if that was an April Fools joke they got me. But I'm pretty sure since the information put's AMD in a negative light that they would have announced it as an April Fool's joke by now.

Interesting CPUs.

Clocking within a power/thermal envelope is going to become more dynamic.


Mobile and tablet processors are doing this as well.

No. My A10-5700 underclocks itself when it gets power constrained. In my case it's magnific, I'd rather get a decrement in performance rather than a straight off restart due to excessive power consumption (I run a 120W peak PicoPSU).

Also, I'm kind of thinking about delidding my A10. It runs rather hot, and I think an improper CPU>IHS bond might have something to do.
