Hyperthreading and Gulftown cpu's

post #1 of 7
Thread Starter 
Is there a definite performance advantage in having hyperthreading on when doing stuff like video encoding or 3ds max rendering (that use all the cores they can get) or is it better to switch off hyperthreading and get a higher overclock to make the 6 physical rather than 12 logical cores work faster? Anyone ever tested it?

At programs that like to encode, decode the more core power the better so the majority of the time HT on will win. Unless gaming were you may lose performance.

Yes, Hyperthreading is definitely worth it esp. when using those Gulftown monsters.

Its kinda wrong to say "you'll loose performance" because in some games HT can lower the FPS but the difference is very tiny (there are some review threads about it on OCN iirc).

Yup, for many parallel workloads you can see something like 10-30% performance gains.

HT does not reduce overclocking potential by that much usualy.

That's why i said you "may" loose performance.

Yeah, well it can be interpreted as "in some game it'll be fine, in others you'll loose performance". Just wanted to say that it really isn't a big deal. thumb.gif
