so today we're going to take a look at the question of can turning hyper-threading off help with your gameplay experience on the PC let's take a look welcome back to techy our city ladies and gentlemen this is brian coming back to you guys today with a video on pretty much hyper-threading versus no hyper-threading in a few different scenarios on my 5820k now in the bus I do have the option of turning hyper-threading off and also limiting the amount of calls that can be used and so with this I decided to test dual core versus dual core for threads and then for cores with four threads versus four cores with eight threads and then finally adding in my 5820k running on six cores and twelve threads though I will say before we get on with this results is that it is a little bit different to comparing a Pentium versus an i3 for example as in all scenarios that is 15 megabytes of level 3 cache on board there so anyway that without further ado let's get on with the benchmarks so the first benchmark we are going to look at is skyrim on 1440p this is the ultra preset and looking at the results here are all five of these scenarios where you've even got the dual core two threads played absolutely fine with the frame rates going through the roof there I mean the minimum was a hundred and eight on the dual core so that's something to note if you're on 120 Hertz and you really anal-retentive but besides that the i3 I mean the i3 here for example the simulated i3 did go over 122 frames per second on the minimum so that's something to keep note about and so pretty much on any five of these scenarios you're going to have a great gaming experience if you're playing Skyrim at 1440p on a gtx 970 so let's take a look at ARMA 3 at 1440p custom ultra settings and now this is a really interesting benchmark to look at especially when we compare it to the previous benchmark where we had the i3 in Skyrim beating the dual core two threads by quite a bit but this time around it's not the case the dual core four threads perform pretty much identical to the dual core dual thread and in this case I'm going to say when I tested these both these scenarios there was no big different like there was no massive stuttering and I'm going to say this for the all the benchmarks I did there was no massive stuttering on any of these games when I disabled hyper threading and turn it on there was no and difference worth noting in any of these scenarios but for what it's worth we can see here when we step it up to fork all four threads versus fork or eight threads there again wasn't much of a difference though it is important to note that the minimum who did score the highest minimum on ARMA 3 with the four core four threads and that was even better than the twelve sorry twelve thread six core result so for what it's worth ARMA 3 it does love the cause it doesn't really like hyper threading but let's move on now to the next game so now we're going to take a look at Crysis 3 at 1080p custom ultra now I wanted to run this at 1080p over 1440 because when I ran it at 1440p it just becomes so graphically intensive on my GPU that even my 970 overclocked to 1600 megahertz takes a serious pounding and this is at custom ultra settings I usually turn maybe one or two really intensive settings off just to get a really nice framerate there as we see here the there wasn't much of a difference at all and I'm actually really surprised with how well the dual core performed because I remember when Crysis 3 first came out I tested it on a Pentium with a 780 lightning overclocked and it performed terrible so they've obviously updated optimize the game for dual cause since then and this game actually plays really well on a dual core nowadays if keep in mind again you've got that 15 megabytes level 3 cache how that affects the senior in this game how that actually affects the frame rates is yet to be seen because when I did do my level 3 cache test I did test it with a 660ti so that being said though there wasn't much of a difference here though it is important to note that the dual core 2 threads in Crysis 3 scored a pretty significant lower minimum than all the other scenarios so for what it's worth in this game you would want to leave your hyper threading on let's take a look at the last game battlefield 4 so for battlefield 4 we went on the test range of 1440p with custom ultra settings here and again this was one of those benchmarks that again didn't make much of a difference whether you had hyper threading off or on you see here there's not much of a difference between any of these numbers you probably put down a lot too variants they've what it's worth the six score 12 threads did kind of win I guess in all scenarios they're slightly though for what it's worth again this is really not a biggie I would say that yeah leaving hyper-threading on in this game would be desirable as well you wouldn't want to turn it off I mean I didn't notice any big stuttering with hyper-threading on versus off so with that being said let's move on now to a conclusion so in conclusion you will just want to leave hyper-threading on I found turning it off made no real-world difference to gameplay and in certain cases it actually took a hit to our frame rates especially when we're comparing the dual core for example to the simulated I 3 also you'll get the benefits of using hyper-threading in other applications so if you're rendering a video it'll definitely take advantage of those extra threads though that being said this it is important to keep in mind that these tests were done on the latest architecture that's the 5820k on Windows 8.1 which in my opinion Windows 8.1 is better for multi-threading than Windows 7 so there could be some truth to the rumors of turning hyper-threading off helps if for instance you're on I 7 9 20 is the first gen hyper-threaded CPUs on Windows 7 so there could be some truth there I mean just going forward we're not going to be using old hardware and all versions of Windows so what it's worth on an Haswell architecture on Windows 8.1 disabling hyper threading is not recommended just leave your hyper threading on it's free performance and it's good performance anyway so that being said if you have any questions about this video please leave a comment and comment section below if you ya like
