    AMD gpu and catalyst control center


      Hi everyone,

      The AMD French support asked me to go on this forum and make a topic for my questions.


      They are i think, simple, but i need to be sure.


      English is not my native language, excuse me for my further faults.


      I have some questions about the fonctionning of GPU (in my case 7870 HD) and AMD Catalyst Software.


      When i use the activity monitor, it always shows 20% of use, even in game. 

      -Is that the minimum it can show, it can measure? 


      -Does the GPU adapt its use depending on the computer capabilities (Im running on an intel core 2 duo E7300 2.66Ghz, this implies a limitation from the CPU)


      Are the following reasonings good? 

      -When the processor is computing, does the GPU downclock itself, when it is waiting for new instructions?

      -In the situation where the instructions arrive sparingly, will the GPU run at 100% of activity for only one instruction ? or will it find a specific cruise speed for this instruction and upcoming ones?  



      Do you think that a GPU running on such system will wear out as fast as if it was running on a faster one?

      Do you think that a GPU on this system would use the same amount of energy compared to one running on a faster system?
