Hi guys, I have my I7-920 at 4,5ghz and I would like to know the performance difference in game between Hyper-threading ON and OFF!?

Some guys said HT is useless for gaming, other said they saw the game goes on smother with HT ON (for example on Battlefield3)!

So what should I chose? smile.gif

Thanks guys!

There is no point in turning it off. Even if you don't get a performance boost in a game, it doesn't hurt you either.

If a game uses more than 4 threads hyperthreading will perform better. If it uses 4 or less, it will perform the same.

Bill Gates wants to reinvent the toilet. With the work that he has done on Windows, he is well on his way.

The only point in turning it off would be to lower temperature and probably even voltage and power consumption!

I would prefer to keep it turn on too, it Can be usefull in same occasions

Thanks guys!

you can always try yourselfs, and let us know if theres a difference ..lol

if i play bf3, i see that 4 cores a busy, about 30-40% load,
from what i hear , the 3570K without HT performs better then the 3770k with HT in games,
thats why most say, buy a 3570k if you play games, and save a 100 bucks ..lol
but what difference are we talking about, a few fps? or 10+fps difference?
im with the others tho, no point in turning it off, or maybe just to see if theres a difference while playing games..
i did turn ht off, for benching, to look if my gflops would go up, and they did smile.gif

I doubt it would like 4.5GHz and HT on...

dunx

P.S. Mine is just stable at 4 GHz with HT on.

Faster...sonic.gif

Sorry for your cpu

My previous one was a bad one and could reach just 4ghz really a lot of 920 reach 4, 2 and some lucky 920 reach even 4, 4-4, 5
