Should I disable hyperthreading?

I used to think that disabling HT helped in games such as BF3, in which I had a horrible stuttering problem on my GT 640, but it turned out that it just wasn't the case (although it helped a bit). Disabling hyperthreading, for me, hampered loading times, caused random lockups but in general things were faster-loading on a single HDD.

 

After adding an SSD, there is now absolutely no difference, and in multithreaded applications the absence of 4 threads is definitely felt more than before. So don't do it.

 

 

@Icuw1pc I highly doubt that Intel's TDP rating depends on whether HT is used or not; the 4670 and 4770 are physically the same. There might be minute differences in electrical draw but overall they should remain the same.

I mostly game on my system and also use Photoshop, Illustrator, and Premiere frequently. This is basically a student's computer where no professional work is done. 

Do I need 8 logical processors? I didn't see many applications taking advantage of all my cores.

I don't really see a point but you can, it may save some power but I'm not sure on that. It's always nice to know your computer can handle the applications in almost every scenario though.

Certainly the Adobe products benefit from the 8 cores though.

Yes it does benefit. Start using one of the applications and open task manager. Look at all the core usage go up on ALL the cores.

Leave them. Why would you disable? They're not harming you in any way.

I wouldn't think you could gain anything y losing virtual cores.

Specs are on my profile page

Thanks. :) I just read that hyperthreading can hinder your CPU's performance since it's basically assigning 2 threads instead of one to a core. (Logic. Yes I knew this before) But I guess the Pros outweigh the cons here. Power consumption is not an issue for me. Thanks  :lol:

It does for a simple reason : 4 threads become 8.Let's say you use 3 of the HT cores,without HT you'd use 2 normal cores,which when HT become 4.Pretty simple.

no why did you get the i7 in the first place?

th ei7 is just a i5 with hyperthreading

I bought an AIO. The only model with a graphics card came with an i7 so I really didn't have a choice. Don't bash me for buying an AIO. I love this thing.

Why buy an AIO

Because my room's pretty compact and I liked the simplicity of it? Look at my profile for my specs and a link to the Amazon website. This thing is a beauty. I also never used an AIO, and I wanted to try new things. I don't think I would be able to go back to a desktop for some time. It's much more pleasant compared to having a giant desktop emiting heat and noise with all the cables flying around here and there. That's just bleh.

What the hell would be the point of turning off hyperthreading? If you bought the CPU with hyperthreading then why not use it?

All the parts are here, just need to get customized cords to connect the motherboard to the front panel.

You could've done a more powerful build inside the SG05 or Elite 130? So many other SFF choices aside from AIO.

 

You should've mentioned that you have a 3770T; you may as well stay away from disabling HT ever again because that 2.5GHz baseclock is not helping.

People stop telling her/him what he/she could have done. Its already done and can not be changed. Not everybody likes picking parts, building own PC (some people dont want to screw things up and want to buy it and use it straight away).

Hyperthreading improves your everyday experience because the tasks can be done faster. It doesnt hinder your CPU lol. The CPU was made to use HT so it is safe leaving it on.

@Icuw1pc I highly doubt that Intel's TDP rating depends on whether HT is used or not; the 4670 and 4770 are physically the same. There might be minute differences in electrical draw but overall they should remain the same.

Hyper-threading (SMT) is a technology to allow two (or more, IBM have 8-way SMT (8 threads on a single core) processor) threads to run simultaneously on a single core. This is because the execution stage is so wide, that a single thread cannot fully utilize it. So with SMT enabled you are functionally utilizing the entire execution stage much better, meaning that more execution units will be productive using power and generate heat.

The core I5 4670k is a core I7 4770k with a defective L3 cache and SMT disabled.
