Ryzen smt on or off gaming reddit Sure, but even the ones posted here show some benefit for SMT off. Though SMT scales better when each thread is not using the available execution resources optimally. After some investigation, we discovered that turning off Simultaneous Multithreading (SMT) can yield notable performance gains, particularly in gaming. For your use case a Ryzen 7 5800X would be a better fit since you wouldn't have the issue of cores from different CCDs having to communicate and any game that performs worse with SMT/HT is likely to be perfectly fine with 8 cores. As easy as it is to turn on and off might as well try it a see if you notice anything. Disabling smt only makes sense if your program can only use less than half the cpu threads, and uses it at 100% per thread. That is indeed true. 3 to 68. I was chasing for the 1%. That was bad for low core count CPUs. Well the problem is Everytime I apply the SMT off game mode profile it restarts windows but I can still see the 16 threads and 8 cores on task manager. 1% lows which resulted in stuttering, after disabling SMT my frames went up to 55 fps and 39 fps 0. Welcome to the official subreddit of the PC Master Race / PCMR! All PC-related content is welcome… On. This is due to cache per core (which is higher with smt off). Long answer: Generally, no, though there are some exceptions. So recently I decided to try turning off SMT in the bios settings to see if it would gain me a performance boost, I saw enough of an increase in performance to decide to keep it turned off. Find the latest news on upcoming devices, learn how to tweak custom firmware, show off your handheld collection, and get device and game recommendations! the difference is ryzen 5 and ryzen 7 both show gains in nearly every single game from turning SMT off. 85ghz boost / gaming clock stock (it has the highest Zen3 stock all core clock rate of 4. Disabling it increases performance on my machine, I've seen others report the same behavior on linux. So let's get to it! DISABLING Simultaneous multithreading (SMT) gives you SILKY SMOOTH high refresh rate gaming. I was recently playing Spiderman PC Remastered and noticed heavy cpu bottlenecking. It's easy to turn off and on and won't break anything. After about gaming for an hour I decided to check temps and whatnot and when I did my games were barely utilizing my GPU and with CPU usage above 80%, the Disabling SMT in older CPUs sometimes gained you performance in older games, but nowadays you're just leaving performance on the floor if you turn it off. 6ghz too) and can easily do 5ghz boost / gaming with some PBO. (except for scoping in with a sniper sometimes - but i'm not the only one with that issue and it persists regardless of SMT) Hey, I've read a lot about ryzen CPUs being horseshit in tarkov, and I can feel it. The Personal Computer. Playing around a bit, Ive gotten my best results at ultra, RTX medium (obvs you can keep off), and DLSS balanced. in Tarkov, and lots of other things would suffer. 3 is pretty impressive indeed for ryzen. 0. lol yea. Jun 12, 2021 · DISABLING SMT ON THAT GAME. SMT off is the way to go. I understand with Ryzen master you can use game mode which effectively does the same thing,but I didn’t I've come across various discussions about individuals disabling Simultaneous Multi-Threading (SMT) on their Ryzen laptops to achieve a small FPS boost during gaming. Issue and solution I'm talking about is on AMD CPUs, someone can test and confirm these results on Intel with HT off. However, this parking thing scared me off a bit. With 9900k at 5ghz and being average of 5-6% faster at 1080p vs ryzen that is likely at 4. My specs; AMD Ryzen 9 3900X 12-Core Processor 3. I had done my original analysis (and posted here ) back when I had a 1950X, and at the time, HPET was reporting significant FPS performance decrease in my games. A community dedicated toward all things AMD mobile. The same cache and clock speeds of its multi threaded cousins. 5 Update 1 (U1) on a Ryzen R7 1700 with SMT/IOMMU/SR-IOV/8 cores/16 threads/ECC RAM enabled and it works! Previously you had to either disable two entire cores or turn off SMT (which left you with either 12 or 8 threads, respectively). Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. Turning it off basically prevents the scheduler from stealing any time from those threads, though you cab accomplish the same by locking them to the correct core and raising the game priority. In the past I had a Ryzen 7 3700X and i disabled smt via the bios and experienced fps gains in Tarkov. Do I need to leave Process Lasso open for it to have an effect, or can I even uninstall it? Does that turn off SMT on my whole system while the executable is open, or is it actually specifically for this executable? Yes, like I said. Usually its better to enable for modern games. Just stumbled across your post. 54 votes, 13 comments. Turning off SMT does actually increase CPU-limited gaming performance on my 5900X by roughly 10% (though it's highly unlikely that I will hit such framerates with how relatively weak my 3080 is at 3440x1440). When SMT is enabled, the game does utilise all cores, but the average clock speed is less, making the However, using SMT, Ryzen is able to make use of the spare execution pipelines regardless. If you wanted to disable SMT u can use task manager and disable threads on an application basis or even use process lasso to do it automatically. Anybody Else with a ryzen cpu… I was inspired by an over-zealous fellow redditor who jumped on me in some other thread when I mentioned that HPET used to negatively impact gaming performance on my Ryzen systems. Rimworld is an example where SMT OFF is way better when fast forwarding in the game, because again, higher clock speeds. This is due to cache per core (which is higher with smt off) Mobo: MSI x570 Gaming edge Cooler: Noctua D15 Ram: 8gig x 4 sticks at 3200MHz Settings in Ryzen master, auto overclocking: Boost override: 200 PPT: 500 TDC: 144 EDC: 192 Settings in BIOS: Package power limit: 850 Pbo limit: motherboard Curve optimizer: -17 SMT off is a bit different than locking to one CCD only as it means threads do not fight with the common resources shared when another SMT thread using cache etc. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon… I just tested ESXi 6. I gave it a go, and saw when flying around New York that 'MainThread' was limiting the frame rate. Likely core count dependent, but my Ryzen 2600 benefited from it significantly. #=====# The goal of this community is to provide a wide variety of information for those considering an AMD laptop. I had tried to disable SMT first with AMD Ryzen master but as soon as I saved to reboot it immediately BSOD. O_o Win 7's scheduler actually handles Ryzen SMT threads correctly, and this relates to Win 10 not knowing which Ryzen thread are physical or SMT, shoving 2 threads into 1 core when under low thread workloads Ever since the 1st gen Core-i, the answer to that question has generally been the same. If I recall it disables SMT and turns off your virtual threads. Tough if only gaming. If you want to compare intel's SMT(intels trademark name for SMT is hyperthreading) vs AMD's SMT; AMD's version seems to be slightly more efficient then intels. 23 votes, 17 comments. You get a highly binned 8 core single CCD chip that hits 4. I wouldn't recommend it As far as I can see people usually just do it because of placebo i tried benchmarking which was best of these options, but honestly the benchmark didn't show a huge difference, i think Auto came out slightly better than Off. I have recently disabled SMT, and lost sleep mode in Windows 10 (which was expected), but now I have reenabled it - and I still can't get the sleep mode back! I can see that SMT is working as there are 24 cores showing in Performance. But should I even be aiming for an undervolt if all I core about is getting 1-2 cores boosting as high as possible? "On gaming, overall there was no difference between SMT On and SMT Off, however some games may show differences in CPU limited scenarios. 0 there is now a new Option in the game Menu for systems with AMD processors. I experimented with having both CCDs active VS switching OFF & ON CCD 0, 1 and also try the same with SMT Enabled and Disabled, in addition, showing before and after fixing the extreme stutter issue found in this game particularly that was addressed in a previous video Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. In any case i will check this theory later. For most games you can turn SMT OFF and run as a straight 16 Core rather than 32 Threads. EDIT 2: I Reopened the game a few more times, in a different place, watching FPS during Static, and high-movement dash/D. Currently with SMT off i'm playing around with the PBO CO, with all core -30 and everything else pretty much on auto to see if it's stable atm. PCPER showed correct SMT behaviours as well. Pretty solid performance. 6M subscribers in the Amd community. I'd like to test if SMT off works but I'm not sure how to if it's not through bios and ryzen master can't apply the changes at all. If you can find one game that still has issues with Ryzen SMT after the Windows 10 scheduling update I would be surprised. The best thing you can do is, to turn off E-Cores and only play with P-Cores, especially if you don't want to use Windows 11 (which I suggest, bc it's trash right now). If you are curious, try it and see. I also noticed the temps dropped a little bit so I gave it an extra 100mhz overclock. And then you had the 3500X 6 cores.

If intel gets about +20% on average for applications that can use it, then ryzen gets about +25%. You will see a small performance dip unless you manually disable it in BIOS then use the extra overhead you get to increase core clocks but you would need about 200mhz to break even. Jump section. Reply reply Ricky_Arno I am trying to measure the power draw with watt meter and I have disabled smt did a power cycle like 5 times and smt is not off, even tried to turn smt off with ryzen master and it still on Bios seems to have saved smt mode as diasbled, I tried to disable cores with ryzen master and it does disable cores but even then smt is not disabled, I disabled 4 cores which left me with 4 cores and 8 Also noticed that SMT is really not contributing to anything usually and mostly makes perfomance worse. Yes but you should never turn off SMT. I’m trying to find the SMT settings in my 2023 G14 bios and so far have found 4 or 5 different posts on Reddit where someone asks the same question and instead of answers, a few people come in and ask why the person wants the setting and then the post is derailed. In non-gaming scenarios, SMT/HT generally provided an average of around 20% performance boost, with a +5 to +35% range. Process lasso makes things easier.

At 8c/8t a user should never notice a difference, really, if they're just gaming and, in probable reality, turning off SMT may be a real soluion for a hot 2700X if the build is gaming specific and in a restrictive SFF case or a poor airflow case. SMT is, and always has been a throughput-focused optimisation to CPUs, improving total IPC by 10-50% (theoretically 100% for SMT2). I imagine with smt off real cores had to be used to less parking which may alter the results. After reading this post and having since upgraded to a Ryzen 5 5600X I tried the process lasso trick and I was getting some serious gains again. Also, if you are a ryzen user. Posted by u/christina_william - 3 votes and 18 comments EDIT: It's the other way around, apparently. I still prefer CPU encoding over GPU, it simply produces better image quality imo, and I also play on 4K, so I would rather sacrifice some CPU perf than GPU. RTX 3060 GPU. FWIW when I was on the 3900x (12 cores, 24 threads) disabling SMT (forcing the chip to 12 cores, 12 threads) definitely helped (was able to squeeze a few threads up to 4. Still 5800X3D handily beats it in every game at least 5-10%, and when the game benifits from the vcache it's beyond 20%. I even use programs like handbrake frequently. e. Short answer: No. Thus enabling SMT, “making 4 cores act as 8”, can make a difference. Auto LLC intentionally introduces voltage droop under load. And then game starts lagging. The point of the comparison is to show how close the 3900x can get to the 9900K. Deus Ex was down almost 10% when CPU limited, however Borderlands 3 was up almost 10%. It's best you leave it enabled since disabling it can affect gaming performance. Turned off SMT and not only did the crashing stop, but I noticed about 5% higher FPS in every game I play. Drastically worse performance. However, I'm somehow getting worse FPS now. 8M subscribers in the Amd community. I got about a 30fps boost on official servers. My fps was more consistent (55-60 fps) once I switched DLSS to balanced instead of Auto. The gaming benefit from turning it off and back on will be negligible. Because you have 6 true cores and FPS fluctuates much less, so you have more smoothness. even highly multi threaded games like battlefield 1 not only gain fps, but also reduce stutters that smt causes when it's disabled, there have been several videos on this sub over the last few weeks showing this. SMT is a trade off not a blanket loss. Heard turning off SMT may help but I didn't find any exact SMT option in BIOS settings. Also my aida64 latency increases from 66. No SMT.
