welcome back to harbor unboxed okay so better week ago now i compared the rise in 9 of 39 her ex head-to-head with the Coronado 1900 K and 36 games and found an average that the new AMD 12 core processor was just 6 percent slower there were a few select titles where the rise in processor came out on top but for the most part it was just a little bit slower still it was a good showing for rise and as the deficit when gaming was negligible for the most part while it pummeled the Knights night arcade for all of our productivity testing following that video I've been inundated with requests to retest the 3100 X with SMT disabled essentially turning it from a 12 core 24 thread CPU into a 12 core 12th read CPU and many are claiming that this significantly improves gaming performance so much so that 30 100x leaves the 90 on our K in its dust I was instantly skeptical of such claims as we've spent quite a bit of time testing first gen rising 7 processors with and without SMT enabled even back in 2017 the gains weren't that amazing and often you'd see a performance regression which ultimately meant disabling SMT wasn't really a good solution moreover since risings initial introduction both windows and games have evolved to better support the core heavy processors and recent testing has found SMT to be very efficient when it comes to gaming performance that said I haven't tested the new Zen 2 processes with SMT disabled but I am expecting to find a similar story so for this test the 3100 X has been configured in its out-of-the-box trim using the Wraiths prism RGB box cool up both the SMT on and off configurations are identical of course with SM T's presence being the only exception so let's quickly go over a few of the games tested before jumping into the performance breakdown with all 36 games first that we have pray and here we see a very impressive 9 percent performance improvement to the average frame rate with SMT disabled in fact even more impressive was the 13% boost we saw for the 1% low result this meant the 1900 K was now only 5 percent faster than 13-hundred X in this title Just Cause 4 also saw a noteworthy eight to ten percent performance uplift with SMT disabled and that really saw the 1300 X close in on the 9900 K testing with Starcraft 2 shows no improvement in performance with SMT disabled when looking at the average framerate though we do see a rather healthy 8% bump in performance for the 1% low result testing with ferrata shows a 3 to 4 percent improvement in performance with SMT disabled and this was actually enough to push the 30 100x ahead of the 99 or ok in this title of course I should know at this point that we didn't test the 99 or ok with hyper-threading disabled so there is a very good chance that doing so will boost the Intel processor performance in this title and other titles where we saw disabling SMT result in a performance uplift moving on a project cars - and here we see a small 2 to 4 percent improvement in performance with SMT disabled and while that is nice to see the 1900 K was in no danger of losing the performance crown in this title frame rates when testing with Total War 3 kingdoms are virtually identical we see a 1 to 2 FPS advantage in favor of SMT disabled but that's pretty well within the margin of error player unknowns battleground sees no more than a 1% change in performance with SMT disabled so nothing to see here we see a very small performance regression with SMT disabled when testing with The Witcher 3 though again just a 1 to 2 FPS difference so within the margin of error so I think it's fair to say performance does go largely unchanged in this title Forza horizon 4 is a mostly GPU bound game but even so we see a very small performance regression with SMT disabled reducing performance by 3 percent isn't a big deal here though it certainly doesn't help the 3100 X close in on the 9900 kf1 2019 does see a small performance improvement with SMT disabled here the 3100 X was around 3% faster again not exactly a big performance uplift but it did narrow the gap to the 9900 K performance in Far Cry New Dawn went virtually untouched at least we see the same 112 FPS on average however as I quite often found the 1% low performance did take a hit with SMT disabled we're only talking about a three and a half percent performance drop here but that's really not what we want to see testing with Strange Brigade shows less than a 1% changed average frame rate though again we do see a reduction in the one percent low figure this time dropping by five percent so it seems you will want to leave SMT enabled for this title if you seek maximum performance quite interestingly while the average frame rate was virtually the same with SMT disabled in battlefield 5 we see quite a substantial reduction performance for the one percent low result as frame rate dropped by fourteen percent so it looks like another title where you really don't want to disable SMT moving on to Assassin's Creed Odyssey and I retested this game more than a few times just to make sure there really was a regression and performance with SMT disabled please note that I'm not using the built in benchmark rather I test the area of the game that you can see in the top left corner here I saw a 7% drop for the average frame rate and a 9% drop for the 1% low so disabling SMT isn't something you'll want to do in this title disabling SMT does help with performance in World of Tanks here the 3100 X enjoyed a 3% boost to the average frame rate and now the 1900 K is just 5% faster though again I should note it is possible to disable hyper threading and that will likely also improve performance for the 9900 K fortnight is the kind of game I'd expect or guess that disabling SMT would help with and that looks to be the case well sort of frankly we're looking at results that are pretty well within the margin of error so not much more to say here really hitman throughs always quite an interesting title that stands out from the crowd for one reason or another here we saw a rather large 10% improvement for the average framerate and now the 30 100x is just behind the 99 or K though the 1% low performance only improved by a mere 2% performance in Resident Evil 2 goes virtually unchanged we did see a 2 FPS improvement but a 1% change is within the margin of error so safe to say performance remains much the same here and performance in the division 2 was also pretty much identical with or without SMT enabled at least when looking at the average framerate we do see a 6% reduction with SMT disable for the 1% low frame rate though so again probably not something you're going to want to do something I noticed when testing the division 2 without SMT was that the 1% low result did tend to actuate quite a bit and that wasn't something I saw with all 24 threads active last up we're gonna look at the shadow of the Tomb Raider results and here we see a nice seven percent improvement for the average framerate but as we've seen a number of times now the one percent low performance does take a hit though this time we're only seeing a three percent reduction in framerate okay so disabling SMT certainly looks to be a bit of a mixed bag the numbers were all over the place and we've only discussed the results for about twenty of the games tested so let's see how things look when comparing all 36 games in one big graph starting with the average framerate results here we see that on average the 3900 X was just 1% slower overall with SMT enabled so it's standard out of the box configuration here we see the performance margin is within the 5% for the vast majority of titles tested in fact I'd say we saw a negligible performance difference in 31 of the 36 games tested so leaving SMT enabled really only improve performance in Assassin's Creed Odyssey while disabling it saw good gains in shut off the Tomb Raider just calls for prey and hitman two however as you just saw when looking at the games individually the average framerate doesn't tell the whole story so let's see how the 1% low figures stack up comparing 1% low performance sees the results swing back in SM T's favor now leaving SMT enabled provided a 1% performance uplift on average across the 36 games tested this means we saw a 5% or better performance improvement and eight of the games tested with a 5% or larger performance drop in just four games so as we found two years ago when testing performance with the risin 7 1800 X disabling SMT can indeed be beneficial but your mileage will vary depending on the game and it's just as likely to cause a performance regression I think it's fair to say what SMT doesn't do is allow the riser 930 100x to beat the core I $9.99 oh ok in games or even catch it I mean it can help reduce the margin in certain games but I think overall it doesn't really help it catch up and I for one aren't too fussed about that we don't need more ways to justify the purchase the 39 does what it does well and if you're after a solid all-rounder the Rison 930 900 X processor is it as we've already seen the 3100 X is plenty fast enough for gaming and where it lacks a few frames it makes up for we significantly improve productivity performance and the ability to tackle more tasks simultaneously it also runs much cooler consumes less power and works just fine with the provided box cooler based on everything we've seen here I don't recommend you disable SMT unless you know doing so improves performance in the games you'll be playing I'm not 100% sure why turning SMT off hurts 1% low performance in so many games at first I thought maybe it was because you go from a situation where the active threads required by the game can be utilized in a single core complex die with SMT enabled to then a situation where those threads are spread across both C CDs with SMT disabled however that doesn't seem to make sense given that the 3900 extra generally offers better gaming performance than the 3700 X and we believe that's because it has 2 C CDs which increase the l3 cache capacity as well as the right lanes to the i/o die I've reached out to AMD for their take on this and I hope if I hear anything back I'll let you guys know in a pinned comment down below overall not much more to say on this one if
