What happens if i disable hyperthreading

Some of the videos and descriptions of what CPUCores will explain it more. For example, it doesn't just touch the actual game itself. It identifies and modifies how your OS processes are running, your non-game processes, your game itself, and wraps it all up into an extremely easy to use Steam-integrated program. The easiest way to understand it is this: Which is better for a game?

Amongst other features of CPUCores. I have a few videos of CPUCores being used by some actual games. Simple, HT tells a single clock cycle to handle 2 threads at once.. For Single thread application having HT turn off will incress core output with out worring aobut thread collision So unless your doing heavey Multi Tasking or applcation that require lots of threads like video rendering, your acutally taking a preformence hit by having it enabled.

Instead, it is game-by-game basis, which makes it real easy. Originally posted by TimDimmDrive :. But that really is an extreme situation, and I can definitely say that CPUCores isn't meant to deal with situations like that. OP, have you ever tried disabling HT to see for yourself whether it improves performance or not?

I did And pretty much every game ran smoother and more stable. Last edited by Yo Wut Sup ; 6 Jul, pm. Yeahbroyeah View Profile View Posts. Or do we have to know the right setting and input that into the software for each game? What I'm trying to say is, what does the gamer have to do other than running the software?

But make sure you know the real facts about the hardware you have. For example, Intel hints at the number of cores by labeling its processors i3, i5, i7, etc.

But in reality, you only get four cores on some i7 processors, and i7 Core processors from the Extreme series may come with up to eight cores. For gaming and streaming purposes, hyperthreading usually does the trick.

However, the speed might not improve in other applications. In part, this is because certain programs cannot efficiently send multiple data strings into a threaded core.

Some users have complained of heating issues after disabling hyperthreading while others say their system actually runs cooler. Particularly on Asus laptops, there is no option to disable hyperthreading but you may find some workarounds online in tech forums.

This article should provide you with enough information to avoid trial-and-error when disabling hyperthreading. You can easily turn the feature on using the same steps. The important thing to note is not to rush things with the BIOS, especially if you are using it for the first time.

Let me reiterate. If I disable Hyper Threading, my computer will be fine and no permanent damage will be done? That's a very interesting statistic. I wonder if that's under load or idle? At the very least the ALU and some of the FPU would have to be duplicated as these comprise the vast majority of instructions.

With HT enabled, you have to add the extra power of execution units being active more often when the CPU is under heavy and sufficiently multi-threaded load to make HT do its thing.

As CPUs get wider to increase instructions-per-clock, a single instruction flow thread becomes increasingly unlikely to contain a sufficiently diverse instruction mix with resolved dependencies within the re-order window to allow the scheduler to use every possible execution unit on every single clock tick.

Jan 14, 15, 1, 78, 2, I may be mistaken, but I think we are discussing the same thing just a matter of semantics. USAFRet said:. My temperature is usually between degrees celsius with vsync on. Yes, you got the whole concept backwards. SMT taps those under-used resources for extra performance at low architectural overhead cost.

I'll agree and say "No, it isn't". It is remapped. But I wrote it that way to illustrate point that resources are duplicated. But they are still a duplication of resources from that resource pool from with operations are performed. You must log in or register to reply here. Should I Disable it?
