00:00:00.080 --> 00:00:08.000
the iphone 6s the entire internet seems

00:00:03.520 --> 00:00:10.559
to agree this is one fast little mother

00:00:08.000 --> 00:00:14.480
and in fact when the first performance results started to surface we found

00:00:12.639 --> 00:00:19.680
articles like this cropping up all over the place saying that in geekbench in

00:00:16.320 --> 00:00:23.920
particular the iphone 6s outperforms in

00:00:19.680 --> 00:00:25.199
some cases the 2015 macbook certainly an

00:00:23.920 --> 00:00:32.320
impressive feat but as we demonstrated in this video here

00:00:29.039 --> 00:00:34.079
where we water cooled the 2015 macbook a

00:00:32.320 --> 00:00:39.360
part of the problem with the performance of that particular device is that it

00:00:36.719 --> 00:00:44.239
drastically thermal throttles so you're not getting all the performance that you

00:00:41.360 --> 00:00:47.039
should have out of it which led my inquisitive mind to go well hold on a

00:00:46.079 --> 00:00:51.680
second is there potentially then even more

00:00:49.440 --> 00:00:56.160
performance under the hood of the iphone 6s what would happen if we were to water

00:00:54.719 --> 00:01:06.640
cool it stay tuned

00:01:06.640 --> 00:01:12.640
the logitech g303 features a lightweight design and advanced optical sensor with

00:01:10.799 --> 00:01:16.159
delta zero technology for precise tracking and RGB lighting to match your

00:01:14.799 --> 00:01:20.479
setup check out the link in the video description to learn more

00:01:18.400 --> 00:01:25.280
okay so first order of business then is to establish

00:01:22.479 --> 00:01:29.600
a baseline while it's being air cooled so what i'm going to do is i'm going to

00:01:26.960 --> 00:01:34.320
run geekbench continuously for 10 minutes recording the scores each time

00:01:31.840 --> 00:01:39.040
it finishes and then tracking how the scores change over time as the

00:01:36.960 --> 00:01:43.360
device heats up from being put under a continuous load so we've got our first

00:01:40.880 --> 00:01:46.000
number 4446 boom let's run it again and record that

00:01:44.640 --> 00:01:48.560
so this is going to be kind of boring to watch um

00:01:48.640 --> 00:01:55.520
you guys can tune out for a bit 44-24

00:01:52.079 --> 00:01:58.079
run it again so this is interesting at a

00:01:55.520 --> 00:02:05.200
controlled room temperature of 24 degrees celsius the iphone 6s

00:02:01.119 --> 00:02:09.360
does not throttle appreciably at all

00:02:05.200 --> 00:02:10.479
over a course of about 10 minutes so

00:02:09.360 --> 00:02:15.200
um yeah this kind of makes the water

00:02:12.560 --> 00:02:18.879
cooling experiment a foregone conclusion but

00:02:16.239 --> 00:02:23.680
what the hey i'm gonna give it a shot anyway so here goes

00:02:21.280 --> 00:02:30.400
now while the rumor mill does indicate that the iphone 6s is indeed quite

00:02:26.800 --> 00:02:33.040
waterproof i do not intend to submerge

00:02:30.400 --> 00:02:38.640
it directly in the liquid because i still need this iphone 6s to work for

00:02:35.599 --> 00:02:41.040
my review of aforementioned device so

00:02:38.640 --> 00:02:44.720
i'm just going to be using an ice water bath

00:02:42.000 --> 00:02:49.440
to maintain it at the coolest possible temperatures and then i will be

00:02:47.920 --> 00:02:52.239
putting the iphone inside a bag

00:02:52.480 --> 00:03:00.000
and sealing it up i'll be using my patented vacu seal

00:02:57.120 --> 00:03:03.959
technique where does your videos suck today they do

00:03:06.319 --> 00:03:12.239
wow can the touch sensor work through the plastic what do you think ah look at

00:03:09.519 --> 00:03:16.879
that it did cool so now we're gonna have to do another 10 minutes of runs here

00:03:15.120 --> 00:03:22.400
and uh we will be back

00:03:19.599 --> 00:03:25.840
four four four three four four four three holy this is

00:03:24.319 --> 00:03:30.640
really consistent four more runs and then we are through

00:03:28.080 --> 00:03:36.799
our 10 minutes of testing and the only real takeaway here is that

00:03:33.519 --> 00:03:40.080
water cooling the iphone 6s

00:03:36.799 --> 00:03:43.760
makes it run ever so slightly like like

00:03:40.080 --> 00:03:46.720
part of a percent more consistently from

00:03:43.760 --> 00:03:53.040
run to run impressive so the iphone 6s basically

00:03:50.640 --> 00:03:58.159
when running CPU intensive benchmarks anyway doesn't thermal throttle

00:03:55.440 --> 00:04:03.200
at all which brings up a couple more questions

00:03:59.840 --> 00:04:04.400
is our testing methodology then even

00:04:03.200 --> 00:04:09.599
relevant so in order to validate that

00:04:07.200 --> 00:04:14.239
we've brought in some other devices we've got

00:04:10.799 --> 00:04:17.280
the htc one m9 featuring the infamous

00:04:14.239 --> 00:04:22.240
snapdragon 810 we've got the samsung

00:04:17.280 --> 00:04:24.639
galaxy s6 edge featuring the exynos 7420

00:04:22.240 --> 00:04:30.639
and we've got the lg g4 featuring the snapdragon 808 this should give us a

00:04:27.600 --> 00:04:32.560
good cross-section of other devices to

00:04:30.639 --> 00:04:38.720
compare the thermal throttling performance of the iphone 6s against i'm

00:04:36.080 --> 00:04:44.160
going to run these phones for 10 minutes and observe how their scores track over

00:04:42.160 --> 00:04:49.040
that period of time this is going to take some pretty rapid data entry in

00:04:47.199 --> 00:04:52.880
order to achieve but i think the galaxy s6 edge is going to come up first here

00:04:53.280 --> 00:05:00.880
52 24.

00:04:56.960 --> 00:05:04.800
okay so uh as expected

00:05:00.880 --> 00:05:07.840
the s6 edge with the exynos 7420

00:05:04.800 --> 00:05:10.479
fell about 10 to 12 percent over time

00:05:07.840 --> 00:05:14.960
okay we saw that coming the g4 didn't thermal throttle at all and kept its

00:05:13.199 --> 00:05:18.240
performance extremely consistent across the board

00:05:16.240 --> 00:05:23.360
but the 1m9 was all over the map

00:05:21.120 --> 00:05:28.880
like all over the place like our first score was higher than any score i can

00:05:25.680 --> 00:05:32.080
find online anywhere for the 1m9 in

00:05:28.880 --> 00:05:33.840
geekbench um and then our later scores

00:05:32.080 --> 00:05:38.240
were way lower so we're going to do two things

00:05:35.680 --> 00:05:41.600
here we're going to rerun the 1m9 i'm going to i'm letting it get back to room

00:05:39.680 --> 00:05:47.759
temperature now i'm not running anything and we're going to throw the zte axon

00:05:44.800 --> 00:05:52.720
into the mix also a snapdragon 810 powered device so that'll give us two

00:05:50.240 --> 00:05:57.600
different data points for this and two separate devices for snapdragon 810

00:05:55.520 --> 00:06:02.400
let's see how that goes all right so

00:05:59.280 --> 00:06:04.479
it's clear as mud now um

00:06:02.400 --> 00:06:09.680
the 1m9 didn't go as high

00:06:06.479 --> 00:06:13.120
and didn't fall as low on the second run

00:06:09.680 --> 00:06:16.319
and the axon started out much lower and

00:06:13.120 --> 00:06:17.120
fell as low as the 1m9 did on our first

00:06:16.319 --> 00:06:23.840
run showing us if nothing else that the snapdragon 810

00:06:20.960 --> 00:06:27.919
is all over the map as far as performances concerned which i guess

00:06:26.240 --> 00:06:33.520
isn't telling you guys anything you didn't already know if you've been keeping up with the fiasco that is the

00:06:31.440 --> 00:06:38.000
snapdragon 810 now let's find out how everything fares

00:06:36.319 --> 00:06:43.199
in the ice water so brandon asked a great question off

00:06:40.560 --> 00:06:46.960
camera about our testing methodology here

00:06:44.639 --> 00:06:51.840
does having the phones next to each other affect the results of the

00:06:49.039 --> 00:06:56.240
benchmark because of the temperature of the water potentially changing

00:06:54.160 --> 00:07:00.080
to which i replied no we should actually be fine

00:06:57.440 --> 00:07:05.840
because as long as there's still ice in the water it will be

00:07:02.960 --> 00:07:08.400
give or take a little bit zero degrees so

00:07:06.800 --> 00:07:15.680
we're just gonna load it up with the four phones here and go ham

00:07:12.479 --> 00:07:18.160
oh come on now

00:07:15.680 --> 00:07:22.560
everything just stop auto-rotating for like oh i guess i could turn it off okay

00:07:20.800 --> 00:07:25.759
i think that one already what

00:07:26.160 --> 00:07:32.160
all our phones are in the ice water

00:07:30.400 --> 00:07:35.759
so i'm going to let them all cool down be running nice and

00:07:34.000 --> 00:07:41.199
optimally cold and then we will do another 10 minutes

00:07:38.240 --> 00:07:45.759
of benchmarks on all the phones in ice water

00:07:43.120 --> 00:07:48.639
all right the time is now 116 we have four

00:07:46.720 --> 00:07:51.840
water cooled foams and we are ready

00:07:50.479 --> 00:07:54.080
to go

00:07:55.599 --> 00:08:05.440
try not to get too excited okay essex edge up first

00:08:01.199 --> 00:08:07.280
55-22 wowza who's going to be next looks

00:08:05.440 --> 00:08:14.319
like it's going to be the m9 wow that's surprising

00:08:09.000 --> 00:08:16.879
3901 all right 35 10 for the g4

00:08:14.319 --> 00:08:20.240
38 61 61 all right well we'll keep doing this

00:08:18.560 --> 00:08:24.800
for 10 minutes 54 13.

00:08:22.720 --> 00:08:29.759
so it took a little kind of staring at it

00:08:27.039 --> 00:08:34.000
waiting for numbers to pop out of the screen to me but i think we've got some

00:08:32.080 --> 00:08:39.200
pretty interesting conclusions so number one the iphone 6s

00:08:36.560 --> 00:08:45.360
is freaking awesome running just CPU intensive tasks the CPU does throttle if

00:08:42.000 --> 00:08:47.600
you load up the GPU um it basically

00:08:45.360 --> 00:08:52.320
doesn't throttle at all under air cooling and what's cool and i can't say

00:08:49.680 --> 00:08:57.440
this about every snapdragon 808 device but i can say it about the g4

00:08:54.560 --> 00:09:01.279
is that it also gives zero

00:08:58.560 --> 00:09:06.240
craps about whether it is air cooled or whether it is in a bag surrounded by ice

00:09:04.080 --> 00:09:11.360
water this puppy performs exactly the same under all scenarios for us

00:09:09.760 --> 00:09:16.160
everything else was a little bit different it looks like the exynos

00:09:13.360 --> 00:09:22.480
processor and the s6 edge performs about 10 percent better under ice water and

00:09:19.040 --> 00:09:26.240
the snapdragon 810 enabled devices both

00:09:22.480 --> 00:09:28.320
the axon and the 1m9 were a little bit

00:09:26.240 --> 00:09:33.040
all over the place but if we consider our first 1m9 run

00:09:30.880 --> 00:09:40.080
a bit of it wow the 1m9 is actually still a little bit

00:09:37.279 --> 00:09:45.200
warm even though it's in water that is definitely cold that's amazing um so

00:09:43.279 --> 00:09:49.600
right so if we throw out that first run with the 1m9 it looks like it actually

00:09:47.760 --> 00:09:56.320
stays at about peak performance when it's in ice water and the axon destroys

00:09:53.920 --> 00:10:00.720
its air-cooled performance underwater across the board showing that the

00:09:58.560 --> 00:10:05.360
snapdragon 810 has a lot of potential but that it has to be

00:10:03.440 --> 00:10:08.640
unlocked by some kind of a design that can cool it whether that's a heat pipe

00:10:07.839 --> 00:10:12.000
or water cooling or whatever the case may

00:10:10.880 --> 00:10:16.560
be so you know what kind of sites that you

00:10:13.920 --> 00:10:22.800
could view on any of the phones we tested today sites made on squarespace

00:10:20.399 --> 00:10:27.519
all of their awesome templates feature responsive design which means they'll

00:10:24.880 --> 00:10:31.519
look good on a monitor like this or they'll look good on anything down as

00:10:29.440 --> 00:10:36.000
small as a phone and their plans start at only eight dollars a month including

00:10:34.640 --> 00:10:41.760
hosting and they've got a bunch of other great benefits as well so you pick your template then whether you want to build

00:10:39.040 --> 00:10:46.320
a blog or a store or like a company information website or i mean really any

00:10:44.320 --> 00:10:49.920
reason you could possibly want to build a website you go ahead you get started

00:10:48.079 --> 00:10:54.959
you use their 24 7 tech support you insert your own pictures and text and

00:10:52.160 --> 00:10:58.720
boom awesome looking website and if you decide to spring for an entire year

here if you're looking for something cool to watch we actually just did the

00:12:00.399 --> 00:12:07.200
manly guide to cable management which now you

00:12:05.120 --> 00:12:11.760
can see the results for here actually this is uh

00:12:08.480 --> 00:12:13.600
well this fell off but whatever

00:12:11.760 --> 00:12:19.600
there you guys get my point very manly very much cable tidy

00:12:16.800 --> 00:12:19.600
bye
