the iphone 6s the entire internet seems
to agree this is one fast little mother
and in fact when the first performance results started to surface we found
articles like this cropping up all over the place saying that in geekbench in
particular the iphone 6s outperforms in
some cases the 2015 macbook certainly an
impressive feat but as we demonstrated in this video here
where we water cooled the 2015 macbook a
part of the problem with the performance of that particular device is that it
drastically thermal throttles so you're not getting all the performance that you
should have out of it which led my inquisitive mind to go well hold on a
second is there potentially then even more
performance under the hood of the iphone 6s what would happen if we were to water
cool it stay tuned
the logitech g303 features a lightweight design and advanced optical sensor with
delta zero technology for precise tracking and RGB lighting to match your
setup check out the link in the video description to learn more
okay so first order of business then is to establish
a baseline while it's being air cooled so what i'm going to do is i'm going to
run geekbench continuously for 10 minutes recording the scores each time
it finishes and then tracking how the scores change over time as the
device heats up from being put under a continuous load so we've got our first
number 4446 boom let's run it again and record that
so this is going to be kind of boring to watch um
you guys can tune out for a bit 44-24
run it again so this is interesting at a
controlled room temperature of 24 degrees celsius the iphone 6s
does not throttle appreciably at all
over a course of about 10 minutes so
um yeah this kind of makes the water
cooling experiment a foregone conclusion but
what the hey i'm gonna give it a shot anyway so here goes
now while the rumor mill does indicate that the iphone 6s is indeed quite
waterproof i do not intend to submerge
it directly in the liquid because i still need this iphone 6s to work for
my review of aforementioned device so
i'm just going to be using an ice water bath
to maintain it at the coolest possible temperatures and then i will be
putting the iphone inside a bag
and sealing it up i'll be using my patented vacu seal
technique where does your videos suck today they do
wow can the touch sensor work through the plastic what do you think ah look at
that it did cool so now we're gonna have to do another 10 minutes of runs here
and uh we will be back
four four four three four four four three holy this is
really consistent four more runs and then we are through
our 10 minutes of testing and the only real takeaway here is that
water cooling the iphone 6s
makes it run ever so slightly like like
part of a percent more consistently from
run to run impressive so the iphone 6s basically
when running CPU intensive benchmarks anyway doesn't thermal throttle
at all which brings up a couple more questions
is our testing methodology then even
relevant so in order to validate that
we've brought in some other devices we've got
the htc one m9 featuring the infamous
snapdragon 810 we've got the samsung
galaxy s6 edge featuring the exynos 7420
and we've got the lg g4 featuring the snapdragon 808 this should give us a
good cross-section of other devices to
compare the thermal throttling performance of the iphone 6s against i'm
going to run these phones for 10 minutes and observe how their scores track over
that period of time this is going to take some pretty rapid data entry in
order to achieve but i think the galaxy s6 edge is going to come up first here
52 24.
okay so uh as expected
the s6 edge with the exynos 7420
fell about 10 to 12 percent over time
okay we saw that coming the g4 didn't thermal throttle at all and kept its
performance extremely consistent across the board
but the 1m9 was all over the map
like all over the place like our first score was higher than any score i can
find online anywhere for the 1m9 in
geekbench um and then our later scores
were way lower so we're going to do two things
here we're going to rerun the 1m9 i'm going to i'm letting it get back to room
temperature now i'm not running anything and we're going to throw the zte axon
into the mix also a snapdragon 810 powered device so that'll give us two
different data points for this and two separate devices for snapdragon 810
let's see how that goes all right so
it's clear as mud now um
the 1m9 didn't go as high
and didn't fall as low on the second run
and the axon started out much lower and
fell as low as the 1m9 did on our first
run showing us if nothing else that the snapdragon 810
is all over the map as far as performances concerned which i guess
isn't telling you guys anything you didn't already know if you've been keeping up with the fiasco that is the
snapdragon 810 now let's find out how everything fares
in the ice water so brandon asked a great question off
camera about our testing methodology here
does having the phones next to each other affect the results of the
benchmark because of the temperature of the water potentially changing
to which i replied no we should actually be fine
because as long as there's still ice in the water it will be
give or take a little bit zero degrees so
we're just gonna load it up with the four phones here and go ham
oh come on now
everything just stop auto-rotating for like oh i guess i could turn it off okay
i think that one already what
all our phones are in the ice water
so i'm going to let them all cool down be running nice and
optimally cold and then we will do another 10 minutes
of benchmarks on all the phones in ice water
all right the time is now 116 we have four
water cooled foams and we are ready
to go
try not to get too excited okay essex edge up first
55-22 wowza who's going to be next looks
like it's going to be the m9 wow that's surprising
3901 all right 35 10 for the g4
38 61 61 all right well we'll keep doing this
for 10 minutes 54 13.
so it took a little kind of staring at it
waiting for numbers to pop out of the screen to me but i think we've got some
pretty interesting conclusions so number one the iphone 6s
is freaking awesome running just CPU intensive tasks the CPU does throttle if
you load up the GPU um it basically
doesn't throttle at all under air cooling and what's cool and i can't say
this about every snapdragon 808 device but i can say it about the g4
is that it also gives zero
craps about whether it is air cooled or whether it is in a bag surrounded by ice
water this puppy performs exactly the same under all scenarios for us
everything else was a little bit different it looks like the exynos
processor and the s6 edge performs about 10 percent better under ice water and
the snapdragon 810 enabled devices both
the axon and the 1m9 were a little bit
all over the place but if we consider our first 1m9 run
a bit of it wow the 1m9 is actually still a little bit
warm even though it's in water that is definitely cold that's amazing um so
right so if we throw out that first run with the 1m9 it looks like it actually
stays at about peak performance when it's in ice water and the axon destroys
its air-cooled performance underwater across the board showing that the
snapdragon 810 has a lot of potential but that it has to be
unlocked by some kind of a design that can cool it whether that's a heat pipe
or water cooling or whatever the case may
