Anyone know if turning off HT messes with the network interface card or other network settings on the board that i wouldn't be able to see the server? 1) Turn off hyperthreading, and your CPU will still run at the same load, just for a longer time, maybe a little bit cooler. It’s there because it’s fairly low cost to add (much cheaper than adding E cores) to get a boost in multithread performance in some workloads, but an extra dedicated core will pretty much always outperform a The extra core being active draws power, and HyperThreading draws additional power, so common sense would tell you that disabling them can save power. Of course there is, without SMT you're able to reach higher clocks for instance and INTEL builds can disable hyperthreading without suffering the same drawback. This gives me up to a 300 fps gain in the range as well as better 1% lows. exe One of the first things I tried to do was turn off hyperthreading on my two most performant cores but I don't have an option to do so in my bios (I have an Asus B460-I).
