HT.. Whats it good for ?

post #1 of 8
Thread Starter 
I have a i7 950, @ 4.21ghz

I game, and bench for stability and to brag on 3dmark

Main priority is gaming.

Ive read alot of both sides for having it on or off.

My question, since the net has biased sides.

What is HT? What is it good for ? What does it help with ?

Will i get better performance with it off?

Thanks

HyperThreading - in simple terms, for every physical core your processor has, your computer will address two virtual cores. It will improve performance. I tend to think that the people who use HT are more movie encoders, doing resource-intensive things like this.

I haven't really heard of HT giving benefits in games, though it may, but I imagine they will only be marginal. Since you're gaming it's really your choice to enable or disable it.

Good for F@H and BOINC, not so much for games.

Certain games run better w/ it off. Experiment to see what works best for you!

Thank you for your input, am I also correct in thinking it uses more power and heat to have HT on ?

Yes, and you can typically OC better w/ HT off. Temps are lower, and less vcore is needed for a given speed.

So, the benefit is even greater if you have the additional speed combined w/ the more efficient nature of HT-off in certain applications.

Most mobos have multiple OC profiles you can save to. I like to set up at least 2. 1 w/ HT on at ~4GHz (for encoding or other similarily demanding tasks), and another w/ HT off at ~4.2GHz+ (for gaming).

Ok thankyou. I shall have a 4.2ghz for encoding and a 4.4 for gaming, If i can hit that high with HT off

Off to find out
