Hi , Im wondering how useful hyperthreading really is , depending on what you want to do, for example :-
i have a quad core and multi task with lots of different apps , fine , i can see the use there , but .......
using a quad core already allocates threads to cores....
next example , and heres the kicker .....
i am using a multithreaded rendering app with my quad i7 , surely the rendering app will try to use the 4 *ghost* cores to perform the same calculations as the real 4 cores , the only trouble is that the *ghost* cores will need the actual electronics of the cpu that the real cores are using at the same time , in example 2 would there be a benefit to turning off hyperthreading ?????
also would turning it off lower temps ?????
opinions ??????
