Hyper-Threading is a technology which was introduced by Intel in 2002 for their Xeon server CPUs, but later this becomes a common feature for consumer CPUs as well.
But these days, there is news about CPU vulnerabilities and scaring a lot of users. Almost, every second guy is asking: What is hyper-threading technology? Do I need hyper-threading? and Does hyper-threading increase performance?
So here is the clear answer.
No, unless you are doing any secret mission job or working for the military. But for any safety reasons, yes, you can disable it.
Hyper-threading boosts about 10% to 15% performance by doubling the CPU cores (by enabling two virtual cores in single-core) and it is only useful when you are doing intensive tasks like video rendering, or live streaming while gaming.
Whenever you do multitasking, I mean to say heavy multitasking; hyper-threading makes the job easy by enabling extra virtual CPU cores.
For most tasks like basic office work, browsing the internet, streaming high-quality videos, etc. you hardly make any use of hyper-threading technology.
