i bit my lip like an hour ago so in this video if i'm kind of like stumbling when
i talk then i do apologize in advance but with
that aside we have smt on the amd side and ht
on the intel side now smt stands for some magic truffle (simultaneous multi threading) so that means if you
basically put it this way if you've got a single mouth and you're eating
a truffle then what happens is with hyper threading and also smt
it splits it off into two smaller mouths and you can now eat
more theoretically you can't there's not like two full-size
mouths compared to one big mouth but it can eat more in
grand scheme of productivity now on the intel side you've got ht which stands
for holy truffle and now that's a different breed that
was sort of in before amd had their smt so that's why it's got
the holly truffle now of course depending on the brand if you
go with amd or intel both truffles are going to do a pretty
good job compared to not eating any truffle at all
though with that aside when it comes to gaming do these technologies work when
you split a core into two threads versus having that
single core with one thread going in and going full ball what is
better for gaming let's find out in today's video after we
roll that intro [Music]
so coming off the back of our 2013 8 core xeon
versus the 10900k and also the 3950x i decided after i did this video to run
a heap of different tests with smt off on amd's 3950x
and then hyper threading off on intel's 10900k and also the 1680v2
and what we saw here is pretty much going to match up with when i made a
video on this in the past the opinion is pretty much going to be
exactly the same or at least the recommendation
if i recall correctly but let's get through the results first with shadow of
the tomb raider 1080p high settings we saw that we gained three fps on the
10900k then with the 3950x we gained five extra
fps and then on the 1680v2 we actually lost
three fps so it really didn't make a huge
difference turning it on or off in this game
really wasn't going to make a world of a difference here but
moving over to fortnite now probably the most interesting of the bunch where
turning off hyper threading and also smt uh
made the numbers worse all across the board it didn't matter if we had the 8
core the 16 core or the 10 core we were getting less performance so do
leave this on if you want to play fortnite
competitively it's going to give you more fps and then when it came to the
one percent and 0.1 percent lows they were virtually the same i mean one
percent lows were winning out in some cpu tests and then the 0.1 lows were
losing out in some other cpu tests but next up we have the division
2 here and this is where uh turning off hybrid threading and also smt
showed us that on the 10900k side we gained three fps
and then on the 3950x we actually got a sizeable boost here going from 167 fps
all the way up to 182. so it started to really scream ahead
with smt off in this title this is the same memory speeds
same clock speeds as the previous video we did
with these numbers and so what we're seeing on the xeon side of things
however we only gained 1 fps so negligible for the intel cpus but it did
make a difference for the 3950x and then over to tom
clancy's ghost recon in vulcan we saw here an actual drop in fps on the
10 900k a slight gain on 3950x and then
a 1fps gain on the xeon so really didn't make a huge difference
here either way that you look at it it seems like the 10900k is probably the
biggest difference here but that wasn't even worth writing home about though
moving over to warzone here we've got a similar trend as most
of the other titles except with the exception of the xeon 1680 v2
which scored significantly lower fps with
hyper threading turned off and that must be the 8 cores
now versus the 8 core 16 threads where doubling up the threads
gives you more theoretical max performance and this game
is taking advantage of that as opposed to the 10 900k
where it's already maxing out the gpu and then same with 3950x it's maxing out
essentially it's cpu um core component tree where the smt's
off or other smt's on so in warzone i would suggest just
leaving hyper threading on or leaving smt on and then we go to the
last title here we got grounded which is going to be released later this
month and i got early access to it so we got here
uh testing out hyper threading on versus off on the 10 900k this made actually a
huge difference going from 102 average fps
all the way up to 127 on the amd side we went from 92
to 98 and then over on the 1680 v2 we still gain a slight boost as well so
all across the board here we were winning
with hyper threading and also smt off however when i was analyzing this game
i also looked at how many threads were actually being utilized in game play
and it seems to only be using eight threads and even within that itself
it's only heavily using two threads of course some other last minute tests here
ccx latency that doesn't change whatsoever on the
3950x side of things cinebench scores will change quite
substantially both on the intel and also the amd cpus
and this is to the tune it can be around 30 so
you'll definitely want to leave your hyper threading or smt on
if you're doing any sort of productivity work that can
utilize all the cores and all the threads your cpu has to offer
though power consumption also during gaming uh really didn't change a whole
lot the 3950x was winning the bunch there
when we tested that in ghost recon and with all those numbers out of
the way my opinion with turning these settings on versus off
remains the same like it did i believe i did this video
two or three years ago but i remember my conclusion was
in general you just want to leave hyper threading and smt on
with your cpus but say for instance we can see that in certain titles
and depending on the cpu you can gain fps now
if you are playing that game competitively and you're in that top one
percent or point one percent of people who play that game and you need to just
extract that little bit extra performance and that is all you do
then perhaps this setting turning it off may be something you want to look into
and of course we only tested six games here but it
does show that it's an easy setting just to
quickly check you just go into the bios and you can disable it and re-enable it
pretty much in two seconds and then you can test the fps for
yourself in that particular title and see whether you need to leave it off
or on but of course in general i will restate this again
in general you just want to leave your hyper threading and smt
on because in general when it comes to working in productivity
it's going to give you much better performance and then of course when it
comes to gaming depending on the game it can give you a
lot better performance as opposed to the other side of the
fence which you're only going to be losing maybe
10 and even at worse with grounded 20 and that's an unreleased title so
imagine that game will get some fine tuning in the next few weeks
and once it's got its final release those differences will be minimized
anyhow hopefully this video was some good truffle for you and you enjoyed it
and if you did then be sure to hit that like button for us and also let us know
in the comment section below have you tried
disabling hyper threading or smt in the past for regular use
if so what was your experience like love reading your thoughts and opinions
as always just like this question of the day here which comes from sally bowie
and they ask is ryzen 1500x and b350m gaming pro for 150 aussie dollars a good
deal and it's a pretty decent deal i mean you
can't go wrong with that it's not the best deal i've seen out there but it's
definitely a decent deal so if it was if that deal was around my
area for that price i'd pick it up so hopefully that answers that question
and i'll catch you guys in another tech video very soon
if you enjoyed this video and you stayed this far and you want to see the content
at the moment it keeps rolling out here at tech yeah city
then be sure to hit that sub button ring that bell and i'll catch you in the next
tech video very soon autobots peace out for now bye
