Video Idea for performance benchmarks

[tenfootgiant]

I tried to find an approriate thread but very few places cover this.  SMT and Hyperthreading can seemingly reduce single core performance.  Many CPU dependent games prefer HT or SMT disabled to improve on FPS numbers while GPU intensive games seem to not care either way.  I know there are going to be some games that make good use of SMT and HT however is it worth shutting off for most instances if you're not doing hard multitasking / multi-threaded work loads and you just want more bang for your buck on every day games?

 

I think this would make for a cool video idea since not too many places touch on this as a simple solution to improving the hardware you have safely, if it does make the difference that most people say it does.  Also, would be good to throw in Precision Timer as well since that's said to hinder performance. Would like to see if it's worth changing for most users for the small improvements they may cause.

 

Very curious to see how it effects multiple different chips in benchmarks / gaming.

This would be interesting. I've not noticed any performance difference with or without Hyperthreading on my laptop. If anything, having the extra 2 threads increase my ability to multitask, which helps increase my performance.

 

On my desktop, I haven't noticed a difference between having 6 threads or 12 threads(Ryzen 5 1600 CPU).

i've seen the exact opposite and notice considerable performance loss when disabling HT.

 

I'm sure some legacy or badly programmed aps might still use only a single thread but i dont know of any that i use on a modern machine vs my retro or legacy machines.

I feel like any compenent, more optimized engine should see this but with enthusiasts that play games like ARMA 3 and CSGO which are more updated versions of older engines without enough optimizations towards today's hardware only care about the performance that a single core can push out, with small bits of improvement when more cores are involved.

I feel like this should be in the techquickie video suggestion spot, but i'm not sure if this topic would fit in a tech quickie

Digital Foundry did a video on just this, they found it depends on the game as to the result and wasn't worth bothering with.
