Impact of Hyperthreading?

What is the impact of disabling hyper threading? How can you do it on a 3930k?

[Electronics Wizardy]

You can do it in the bios on almost all boards. Or disable the cores in windows.

 

It depends on the program, but its normally a gain in performnace for almost all apps, or no change. Its normally a 30% peak improvement.

It'll be somewhere in the BIOS, where exactly depends on the motherboard itself. As for performance it's going to be about 60-70% of what it was in multi-threaded work and single threaded performance won't be affected unless you use the overhead you gain back to increase clock speeds.

Would you recommend it for gaming? I have had problems in the past getting GTA 5 to hold at 60 FPS with a GTX 1070, i7 3930k @ 4.4 GHz, 64 GB DDR3 RAM, and 2 x 240 GB RAID SSDs.
