Better Clock speeds by disabling multi-threading?

Recommended Posts

Posted · Original PosterOP

Im using a B450 Asus Tuf gaming motherboard and im planning to upgrade to the 8 core 3rd gen ryzen, i want to get the highest clock speed possible because i only game and im sure the 8 cores will be more than suffcient. I know that disabling multi threading reduces power consumption so this makes me think that theres potential to get better clocks by disabling this on lower end motherboards. Am im being nieve or could this potentially help me out if im going to be limited by the power i want to push through my vrm, further more would this be enough to make the 12 core a viable option on this motherboard?

Disabling SMT does increase clock speed headroom due to the fact that the temperature is lower. However that's a tiny gain even by single core benchmark standards. In real world gaming it will fall flat as being straight up worse than lower frequency with SMT, unless something else screws up which was the case with first gen Ryzen

It's stupid. For.a gaming rig 8 core overclocked well on a good board will beat a 12 core on a weak board.

The 8 core Ryzen 3 series won't consume a significantly higher amount of power, maybe 10-20w more.

Disabling hyper-threading is unlikely to help you achieve higher clocks.

I agree, sorry to say but it is a very stupid thing to do.  Your OC is already gonna go to its limit give or take 100 or 200Mhz if you disable HT.  Your losing soo much CPU power, not worth it.  I wouldn't even do it if I can get a 5Ghz 9900k to 5.2Ghz compared to 5Ghz and what not as example.  Those 8 extra threads on a 8 core will increase HT apps performance by avg 25 percent on apps like Premiere and Photoshop or CAD or DAW or Studio Max or Maya,, etc...

Ok so heres the thing tho, I know im going to be super limited on power and so i am fairly sure im not going to be able to fully max out my cpu on ambient anyway, except if i get a fairly significant power drop from disabling smt im going to be able to push that power towards the portion of the performance i care about more. 16 threads is more than i need end of story, unless you are genuinely saying that having 16 threads vs 8 threads in a game makes a noticeable genuine difference (based on my research this is basically nothing in games that arnt super cpu heavy, and these were with lower core count chips also, for example 8600k vs 8700k is basically nothing when there both at 5Ghz, and thats only 6threads vs 12 threads, so im already off to a better start anyway) then i dont care about having 16 threads, even if the preformance gain of the clock speed is also fairly negligible, because mostly i just want to affordably get the best clocks i can, id rather invest in cooling than a motherboard if i can get away with what ive got, which currently i can im just trying to stretch my build as far as it will go. 

 

As for the 12 core being stupid i was fairly certain it would be and wasnt really even considering it lol, i was just hoping i was wrong haha

 

Also this is basically just an attempt at me finding an alternate solution to lowering VRM temps lol, its coming down to either this or zip tieing an 80mm on that bitch and honestly id rather not lol

Yes your absolutely correct, except thats not my use case, my use case is exactly the opposite. I dont use Photoshop or CAD or anything like that, i play games, code, and i like to overclock my stuff, thats about it, so that 100-200mhz is exactly what im looking for.

In that case your fine disabling it!  This is why people would get i5 CPU and i3 since it had no HT but was great for gaming.

Any idea what i might be looking at for powerdraw drop? like 10%... 20%? Also thanks for your help!

It is going to be about 25 to 30 watts less draw.  Maybe less or maybe bit more depends on CPU.
