[ 0.083400] CPU0: AMD C-60 APU with Radeon(tm) HD Graphics stepping 00
if so, this seems to be a general misbelief of how amd's (as well as intel's) turbo technology works. in fact, you can't set the tubo frequency manually and the cpu also announces its regular clock speeds to the system but in cases where the thermal specification (TDP 9W) permits the cpu raises its clock speed internally as long as it can before it drops back to the safe waters of the regular speeds. as a matter of fact, the turbo-frequency is not displayed as such and for the user, it might just appear as if the cpu is running on its highest nominal clock speed.
note that in order to follow the thermal specs some cpu's might enter turbo e.g. only when only one core is under load and the other can enter some light sleep state.
there is a really nice cpu information utility for windows called cpuz but i can't recall if this is able to determine when exactly the cpu enters and exits turbo mode.
so the bootom line here seems to me that your cpu is probably fine and ubuntu is doing a great job getting as much as possible out of your hardware that might clock at 1,33 ghz more often than you would think
have a nice day,
