Discussion about simultaneous multithreading or hyperthreading in gaming performance
Are you wondering if turning off Simaltionary Multitreading or Hyperthreading really affects performance in non-gaming applications more than just slightly? You discovered your game struggles with multithreading on your i7-9750h but works fine on your i7-13700k, even though both have Hyperthreading active. This suggests the 13th generation might lack SMT support compared to the older 9th generation. Regarding other programs, disabling SMT could noticeably slow down applications outside of gaming. Please let me know if this isn’t the best spot for your question—I wasn’t sure it fully fits here.
SMT stands for AMD's Hyperthreading. Intel doesn't employ this technology. The i7 9750H and i7 13700kf both support Hyperthreading. The laptop's CPU features six cores with Hyperthreading (12 threads), whereas the 13700kf includes eight performance cores with Hyperthreading (16 threads) plus eight efficiency cores, which operate at around the same level as the i7 9750H cores. Turning off Hyperthreading on the i7 9750H reduces it to a six-core, six-thread configuration similar to older i5 CPUs from the 8000/9000 series. Removing both efficiency and performance cores significantly impacts performance, though results depend heavily on the application. Hyperthreading originally offered modest gains—now it delivers much better performance in many games and programs. Efficiency cores add further benefits.
Hyperthreading refers to a branding concept. Simultaneous Multithreading describes the actual technology. AMD didn’t create a unique name; they just label their version as SMT.
I thought SMT was separate from Hyperthreading. But now I'm really confused. If both CPUs support Hyperthreading and the game works fine on one system with basic specs but crashes on another, it seems like the game doesn't handle multiple threads well. I have no idea how to fix this. Ugh...
I updated the BIOS about three months ago once the PC arrived. I’m unsure if a newer version is available. All my drivers seem current, except for one that’s listed under the optional category in the Windows update section, where I limited them to the existing P-Cores.
The game is Persona 5 Strikers. I've shared updates about it in the past, and this was the latest post from last night.
Check the newest BIOS updates at the official site. This process doesn’t automatically install drivers—either handle it yourself or use specialized tools for your graphics card.
The method involves assigning CPU affinity for the game to 2 cores, which resolves the problem. Ensure these aren't e cores involved. This seems like a common issue affecting many users—likely due to a faulty port. It appears the CPU isn't the problem.
