Does Hyper Threading affect gaming performance?

post #1 of 25
Thread Starter 
Depending on the game, the cpu could increase performance quite significantly. But does HT increase performance significantly in gaming? I have it turned off to keep my overclock nice an cool.

It doesn't since about a handfull of games support it. Though if you game and multitask at the same time, you might.

You mean Hyper "Threading"? Becasue Tessellation has to do with DX11 and graphics.

For Hyper Threading, it would really just depend on if the game or application actaully uses more than 4 cores. If not, it really wouldn't matter if you had it enabled or disabled. If it does use 4+ cores, then you should see an increase in performance.

BC2 is an example of a game that can leverage multiple cores. Even so, when i check my cpu usage it is only leveraging my 4 physical cores, the hyperthreaded (logical cores) are not being used at all.

I would say that in general hyperthreading will not affect your gaming performance.

No. If you're talking P4 HT, then maybe.

Hyperthreading essentially makes each processor core into 2 cores to windows. If you have a program that uses 8 threads (games use 4 at best), then you have 8 half cores to process stuff with. Now the question is, what's faster, 8 half cores, or 4 cores? Intel says 8 half cores is better, which really has never made any sense whatsoever to me.

I said P4 maybe, because most games actually do use 2 threads.

from what i can see from a quick google search HT can sometimes hurt performance

I can't speak from experience as mine does not have hyper threading but from the benchmarks I have seen a majority of games see no benefit from hyper threading. Some do. Best way is to test for yourself, on the games YOU play. Start up fraps and record min/max/average FPS with and without HT and compare results.

Lol I love this guy HYPER TESSELATION IS OVER 9000!!!!!!
