Do you disable hyperthreading? (poll)

[Regeneration]

OK, I take back everything I said about hyper-threading and gaming. The benchmarks lie.

Like @advanced3 said, multiplayers run worse without HT. I just felt it myself.

It is better to keep it ON for gaming despite security concerns and benchmarks.

This is good for reference, 9700k x 9900k, practically only ht differs.

Hyperthreading wise nowadays does not suffer performance issues like used to, if you play simulator games that uses mainly your cpu then you must turn ht off, few games do that, no point turning it off unless you have problems with the heat, if you have heat issues I would advise disable hyperthreading and lower cpu vcore, you will see a considerable amount improvement on temperature.

check Car Mechanic Simulator 2018 benchmark, that is the only time having hyper-threading is bad and this has not changed since hyper-threading came to exist, simulator applications/games suffer with hyperthreading.

I would only advise disabling it if you have a hex core or greater. Otherwise, that can neuter performance on some games.

It is noticeable even with hexacore and more.

It varies by title according to multiple videos. The experience varies.

I can run it disabled (I do)......buuuuuuut I also have 16c/32t cpu, lol.

I'm a C/C++ Software Engineer and during last a couple of weeks I've been testing systems with Intel HTT disabled and enabled. Please take a look at 4 Video Technical Reports:

Intel Hyper-Threading Technology and Processing Power of a Computer System ( VTR-004 )

Intel Hyper-Threading Technology and Linpack Benchmark ( VTR-005 )

Intel Hyper-Threading Technology and Number of Processing Threads ( VTR-006 )

Intel Hyper-Threading Technology on a Heterogeneous Computer System ( VTR-007 )

What's the takeaway of those vids?

 

[R-T-B]

I'm sure it's that hyperthreading doesn't increase your silicons raw computing power. He was saying something to that extent in another thread.

To which I replied something along the lines of "of course it doesn't, but it never was supposed to either, the whole concept is to increase computing throughput when multiple applications vie for the same core, and when one is stalling, the other can do work."

I think this'll be similar but we shall see. Can't watch vids from here.

My take on this is that you still need malicious code to run on your machine to exploit these vulnerabilities, just like any other virus/malware? Or am I wrong?
