so personally i kind of feel like if
you're a company
and you sell or manufacture a product in
different locations
those products should either have the
exact same parts
or at bare minimum act the exact same
right i feel like that's a pretty
reasonable request
well we know that samsung is currently
selling their main flagship the galaxy
note 20 ultra with different
processors and different cooling systems
inside
in different areas of the world and
today
we're gonna find out if those two
different versions act the same
or not we'll even take apart both phones
and swap the copper and graphite cooling
systems between them
to see if that causes a difference in
performance as well on the left i have
an international
phone which has the exynos processor and
a copper vapor chamber inside
and on the right i have a white us phone
with a qualcomm snapdragon processor and
a graphite cooling pad inside
in my previous video i erroneously
mentioned that it was the exynos that
was paired with the graphite but it
turns out that samsung
is using qualcomm chips in some markets
outside the us
as well so my phone actually had a
qualcomm chip inside
that error though actually kind of makes
this test all the more important
since it's not easy to know which
version of the phone you are actually
buying
it's time we find out if one build of
the note 20 ultra
is better than the other should be
pretty interesting let's get started
[Music]
there will be two variables that we're
checking on during this test
the processors and the cooling to start
the test off i have both phones charged
up to 100 percent
and both brand new phones are on their
very first charge cycle
i've downloaded a benchmark app that
stresses the processor to see how much
processing it can handle and it gives
the phone a score
the higher the score the better the
performance you can see on the left we
have the arm v8 cpu
which is samsung's own architecture for
the exynos 990 system on chip
while the phone on the right is using
the qualcomm snapdragon 865 plus
as its brain power i'll hit run at the
same time on both phones
and wait for a few minutes while the
phones do their thing the difference
between the qualcomm and exynos mobile
system on chips is similar to the
difference as we see between intel and
amd computer processors
both are built to do the same job but
are completely different products
and perform differently we can already
see that the us-based phone with its
qualcomm chip and graphite cooling
finished first a whole 15 seconds faster
than the exynos version
and finish with a single core score
that's 87 points higher than the exynos
and a multi-core score that is 456
points higher
that's a 16 power difference between the
two models
and also just for reference my last
year's note 10 plus scored a 2500 on the
multiscore
i'll show you that a bit later in the
video which means that the multi-core
score performance of the exynos chip is
actually
closer to last year's note 10 model than
it is to this year's
note 20 ultra counterpart kind of
embarrassing
i'll keep track of the temperature
throughout this process as well i did
try monitoring it through the internal
app
and all of the temperatures matched up
between both devices pretty evenly
qualcomm did always run a few degrees
cooler but that's not a huge difference
as you'll see throughout the video
i also measured the temperatures
externally as well throughout the test
a hotter phone doesn't always
necessarily mean the processor itself is
hotter
it could just mean that the cooling
system is actually doing its job
of pulling heat away from the processor
and pushing it to the outside of the
phone
the outside of the phone is warming up
more as a result of that exchange
i performed this benchmark eight times
i'll let you see the results of each as
they take by
remember we'll do this all over again
once i've switched out the cooling pads
underneath the motherboards
just for kicks and giggles the
performance difference between the
qualcomm
and exynos is consistent even as both
phones heat up
these benchmarks are kind of the
equivalent of playing an intense game
for about 30 minutes
remember this is just one test to get
really accurate results i would probably
need to go buy a bunch of phones
but since i've already got three of
these thirteen hundred dollar flagships
i don't really wanna buy any more you
might also have noticed that the screen
color is a bit different with both
phones
i'm pretty sure i have the brightness
turned all the way up on each
but it makes you wonder if there are
other components that don't match up
between the variants as well
for the last test i added a little
fishtank aquarium lcd sticker on the
back of the phones
these stickers heat up and tell what
temperature the surface is underneath
the sticker
then i started up the last test and
monitored each phone
the processor is located in the upper
half of the phone and there was always
about a four or five degree temperature
difference between the two
exynos being the hotter it turns out
that the
fish tank thermometers don't work out
all that well since both phones blew
right past that hottest temperature
that these stickers could record now we
know that if the note 20 ultra was a
fish tank we'd have a lot of dead fish
so good thing it's not a fish tank i'm
just going to
take these off and we'll forget about
this part
so after running the benchmark 8 times
on both phones our battery percentage is
at 84 on the exynos and 86 on the
qualcomm
so one processor is performing better
and is more power efficient at the same
time
which is embarrassing yet again for the
exynos let's talk about the results from
this first round while i take apart the
phones to pull out that cooling system
after all it's not a jerry rig
everything video without a tear down
in all eight tests the qualcomm variant
of the note 20 ultra
crushed the exynos variant with a nearly
16
performance difference every single time
remember my last year's note 10 plus
scored right about here
even after i've been using it for a year
so it's almost more worth your time to
skip the exynos chip entirely and just
get last year's phone model
if you were just worried about processor
performance sometimes apps only use one
core and sometimes apps utilize all the
cores
so this benchmark is testing both
multi-core use as well as the single
core use
and that single core graph is down at
the bottom now that my mystic bronze
international exynos note 20 ultra is
opened up
we can see that it indeed does have the
copper cooling vapor chamber inside
i'll peel out that being careful not to
damage it since we are going to plop it
inside of the white us version of the
phone
underneath the qualcomm processor we can
see that it has a little wicking grid
inside to pull the moisture from one end
of the vapor chamber to the other
it's a pretty sophisticated system i'll
open up the mystic white us qualcomm
variant of the note 20 ultra
and we can see the graphite cooling
system beneath that motherboard
which is what we expected to find we
have yet to see if one cooling system
performs better than the other
but by swapping them and performing the
load test one more time
and comparing the numbers we should get
a good idea of how much each cooling
system is helping out
now that i've inserted the copper
cooling system into the qualcomm foam
we can put the graphite cooling system
in with the exynos processor
since the layout for the cooling is
exactly the same across both models
they have the same size and footprint of
course now they don't have the factory
seal anymore with the frame of the phone
so it's not an absolutely pristine
example but it's still worth taking a
look at
i've got everything put back into place
connected like little legos
and screwed down so we're ready to start
the benchmark test over again
remember the international exynos phone
is on the left and now has the graphite
cooling system installed
and the us version is on the right with
this qualcomm and new copper cooling
system installed
running the 8 test takes about 30
minutes which is plenty of time for the
processors to start heating up
and start throttling a little bit this
is also where i put my own 10 plus into
the mix and got his 2500 multi-core
score
we'll let the rest of the test cycle
through i'm definitely not the first
person to point out the performance
differences between the exynos
processors and the qualcomm processors
aaron from mr who's the boss did an
excellent video comparing the s20 ultra
variants earlier this year
and got nearly the same results i did
it's kind of hard to defend
samsung on this one it's as if toyota
was selling a six-cylinder truck in the
usa
but a four-cylinder truck everywhere
else without telling anyone what's under
the hood
i'm not the biggest fan and this is also
why my note 10 plus is probably going to
be my last samsung
phone it's time for me to branch out
after this one dies
now let's see if the cooling systems
actually made any difference in
performance
overall qualcomm still wins massively in
the second set of tests
the black line is qualcomm's new
benchmark and the green line is the new
exynos benchmark
there is still about a 20 difference in
performance pretty much the whole time
throughout all the tests
the qualcomm processor is clearly
performing better
but what about the cooling systems when
we take a look at the original scores of
the us qualcomm model with its graphite
cooling
and then overlay the copper cooling
scores on top we can see that the
performance actually decreased about
three percent across the board this time
around
this is quite possibly just a factor of
the phone being taken apart and the
cooling system not being adhered like it
was at the factory
but it is still consistent all the way
through those eight tests
and if we take a look at the exynos
processor which started out with the
copper cooling
which is the graph in red and we overlay
the new scores with the graphite pad in
green
we can see they also have decreased
about three percent across the board
same as the qualcomm super interesting
judging by this set of tests and our
rather small sample size
it looks like the cooling system between
the two phones doesn't matter very much
since the scores were relatively
consistent across the board both times
and then both phones dropped equal
amounts when i pulled out the cooling
system and swapped devices
it's also fun to note that the exynos
variant has five percentage points
less of battery now than the qualcomm
version does even though they've done
the exact same things
there are little differences all over
the place in conclusion though
the biggest difference between the two
note 20 ultra variants
isn't the cooling system it's mainly
just the processor itself
and the difference between those two
processors is huge
let me know what you think of this whole
exynos and qualcomm thing
do you think samsung should be allowed
to sell an ultra phone with different
internals like they're currently doing
i kind of think they shouldn't if it
acts like a different phone it should be
called a different phone
and when someone ends up with an exynos
they're not getting the ultra phone they
paid for
but let me know your thoughts down in
the comments come hang out with me on
instagram and twitter
and thanks a ton for watching i'll see
you around
