time now to check on the thermal performance of the samsung galaxy tab s8 ultra that i have
14.6 inch screen this version has 8 gigabytes of ram 128 gigabytes of storage the wi-fi only model
i'm going to test out various different benchmarks stress it right out and see just how hot is that
snapdragon 8gen1 going to get will it thermal throttle and if so how much how hot is it going
to get will it become a overheating throttling mess like i've seen in some of these snapdragon
8gen one phones well let's find out so let's jump straight into this i have right here you can see
no recent apps so the memory is clear now i have the eight gigabyte ram version with 128 gigabytes
of ufs 3.1 storage the app i'll use first is 3d mark here now this is the wildlife extreme test
that i'm going to do which a lot of people before my other video said that's not realistic but it's
going to push the hardware to the absolute limit it's 20 minutes long so we'll see just how long
will it last before it starts to throttle down that performance and with my thermal imaging
camera we'll take a look and see just how hot is it going to get so let's start this now okay
so it's just about to finish and there we go it's finished you can see it's throttled down here to
37.4 percent of its performance and that happened around about the five minute mark the fifth loop
starts to dip down and on the six definitely and it was quite stable but look it started to
actually pick up a little bit on the end there so i'm gonna have a look at the thermals now with my
thermal imaging camera we'll see just how hot is it getting after 20 minutes of stressing it out
all right so i can see that just around the top here that's where the chipset is
33 degrees celsius so that's actually not too bad 33 because i've seen 50 degrees on the xiaomi 12
and the 12 pro i will flip it over now and we'll take a look at the back because that's where i do
feel a bit of heat and you can see that that's excellent that is really good about the same
kind of temperature so 33 degrees after just 20 minutes of the wildlife extreme stress test
now the next set of benchmarks to really stress and push it is going to be this one and two-two
benchmark to make things interesting i'm also going to add a different form factor but with
the exact same chipset and it's this the xiaomi 12 pro now this model here has the same chipset
which of course is that snapdragon 8 gen 1. but in the smaller form factor is it going to get a lot
harder how much hotter it's going to get how much more is it going to throttle so in tutu on both of
them just check there's nothing in the background here there's nothing running in the background
both of them are cold all right so it's even it's fair here ambient temperatures are 24 degrees
celsius the celsius at the moment so antutu benchmark here on both of these open them up
all right and just confirm they're both version 9.2.9 you can see the previous scores quite a bit
of a difference there samsung to me have throttled it down a little bit but what they've done makes
more sense as you'll see later on because it doesn't get as hot so what i'll do is test
this again and let this run and we'll check on how they are the performance drop on the next run so
remember that score and we'll see what's going to happen here now with the phone versus the tablet
all right so they just finished up a bit of a difference there quite a big difference between
them so looking at my thermal imaging camera you can see that the front of the screens here
the xiaomi's at 35 degrees and we're only at approximately 27 or so on the s8 ultra what
i'll do now is run the benchmark again because i want to see how much are they going to throttle
so here we go let's just do round two on this the benchmark results will get out of that screen
and we'll do it test again
okay so they've just finished up and we've dropped
about 20 000 points only on the xiaomi 12 pro and we actually got a better score here
on the s8 ultra which is unusual so i'm going to do one more loop here and then i'll call it
quits but i will check on the last loop i'll have a look at the thermals so let's do this test again
all right so the xiaomi has finished up first there and it does throttle down even more but
not by too much so that's only now dropped by approximately what about 10 000 points
and a little bit more than that about 17 that it's dropped again and here we go you can see that now
the samsung has dropped a bit so the best score it got was 903 000 points so it's gone down a little
bit but what about those thermals you can see that it's up to 41 degrees here on the front of
the phones here with the xiaomi so the snapdragon 8gen one and a phone of course smaller form factor
this makes complete sense it's it's normal all right this is dissipating so much more heat it's
really large so it's the front of them let's flip them over and you see the back of the phone here
getting a little hot 40 degrees almost but not too bad that's good the worst i've seen actually
get is up to about 50. what about the huge tab s8 ultra here so the back of that one oh look at that
that's really good let me just move this third marker here onto where it looks quite warm so it's
really only getting up to about 29 degrees around there so that's excellent so far with the thermals
on it i mean it's just dissipating and get really getting rid of that heat so quickly on the larger
tablet it makes complete sense that the phone's struggling here getting a bit hot to the touch
and it's time to now really step it up a notch here play the most demanding game which is genshin
impact i'm going to run the highest possible settings the highest preset but i will set
it to 60 frames per second it's going to really push this game hard and we'll see if it runs into
any noticeable throttling that i can detect now unfortunately the game launcher here doesn't
give us a frames per second count and that game plug-in that a few people have asked me to run
it doesn't show up okay the friends per second it just states it's not supported so i can't run that
yet so it took a little while to load the game in here and you can see that there's pretty fast so
settings wise to take a look what i've got here set just to confirm that under graphics
you can see custom because i have it set to this so you go highest all right and
it's just gonna stand i need to restart but i've already done that so it's still already in the
highest possible settings and then 60 frames per second overclocked so i'm going to now play this
for approximately an hour okay and we'll see how hot it gets and will it lag out completely
now i've only been playing for about 35 minutes and there's no point me really going on too much
more now i've seen a few lags it definitely does lag out down then just a few frame dips
on these top settings which is to be expected but what i have seen
is the thermal's just topping out about 37 degrees that's it and you can see right now
with my thermal imaging camera that yes it's about 35 degrees and that's really all it's going to get
up to and i'll just quickly flip it over and we'll have a look at the back now after 35 minutes of
really one of the most demanding android games here and now look at that well getting up to
about 37 so i have seen it peak around 38 but 39 it's not really going over there now bear in
mind that if you do use a case or you've got the cover on it that it will get a little bit hotter
really great to see that this did not turn into an overheating throttling mess
what i have seen with some of the snapdragon 8 gen 1 phones they just simply don't have
good thermals in there haven't put enough copper transfer heat pipes whatever it's not good enough
because i've seen some of those phones completely just crash and burn closing a demanding game like
gen chen impact completely booting you out of it not gonna happen here with the samsung galaxy s8
ultra it just goes and goes and goes so i don't have a case on it so if of course if you're gaming
with the case i don't currently have any on hand or a cover over it then it will get a little bit
hotter there but i do think that samsung have put a lot of work into this to make sure the thermals
are good so it does throttle as we're seeing with the wildlife extreme stress test that's normal
this is how these chips work when they're at the top clocks they're getting very hot it's entering
a bit of heat eventually they're going to drop down those gpu clocks and the cpu clocks in order
to control that heat but a tablet like this it has a massive amount of space it's got an alloy body
unibody and it is simply using all of that really as a huge passive heat sink to dissipate that heat
without any issues so fantastic thermals on this i think in my time testing it and now gaming was
something as demanding as gen chen impact not a problem the only thing is as i pointed out my
first video a little large and uncomfortable for gaming such a huge tablet like this so
make sure you check out my other videos on samsung's galaxy s8 ultra there will be an
emulation video that i'm currently working on and that will be pushing it again to the limit
to see what kind of performance we can expect with popular emulators with the s8 ultra here
