Just disabling hyperthreading without changing any other settings increases ST performance consistently by 2-3% in my tests, about the same as a 100MHz core clock bump. Hyperthreading uses residual cycles of a main core to get more work done. And if someone's afraid of the power draw, you can combine an undervolt with a power limit, so you'll still have the great gaming perf increase and less power consumption in heavy AVX loads. You also need to disable CPPC, CoreBoost, and C-States. Edit: Not sure if i would recommend doing this for this game only as it will destroy performance in other games. Whilst the game itself might have just one main thread that does most of the work (80% in the original Skyrim for example) Direct X and other drivers and dynamic link libraries need to use cpu threads as well. I have what is probably a really stupid question that has always been a slight curiosity of mine. I think I just about understand what hyperthreading is, thanks to this video , but I don't understand why disabling it might improve performance in games. A hyperthreaded dual-core would still have two cores. How Much will Hyper-Threading Boost Processing Performance? Based on guidelines from multiple server manufacturers, I use the following rule of thumb. Not worth worrying about. If you have a i7-4790k, your highest OC will be limited by your tolerance for a unsafe Vcore before you run into thermal limits I think hyperthreading is a much bigger plus for I3 than for i7. Then there is the x3D cache Disabling the non cached CPU might provide a slight to moderate performance increase. BLUF/TLDR: Go into your BIOS, disable all CPU core idle power states ("C-states"), and your performance in PoE (and everywhere else in your OS) may potentially improve, sometimes dramatically. Personally hyper-threading is disabled on my i7 4770K and it generally helps with games that benefit from single thread performance but I don't expect it's helping that much with GTA 5. If simplifying the design of an X64 chip can be done by removing hyperthreading, this could improve single-thread performance by stalling the chip when a slow memory load needs to be done, allowing it to cool off, and then resuming at a high clock. Not sure for AMD users. But this i7 12650h has 6P core and 4E cores that doesn't need hyperthreading at all. These logical processors are essentially what people call t I read recently that there are some Intel users who buy highly-binned chips and then disable cores and hyperthreading so that the remaining cores can utilize the extra cache/thermal headroom to increase single-thread performance. The answer is real easy: Hyperthreading is not a real CPU. cbqe yrvblw ezgtoc eeg dph llpdhwtl eqlh tnf ulmhwx nfm
