we need to talk there's been a lot of
positive talk about apple's m1 chip sets
lately have you got the new m1 macbook
pro yet because i've tested out it's as
fast as promised
battery life is incredible any chance
you know anybody that can buy the
5 000 maxed out 16-inch macbook pro that
i bought
a month ago because that's how good the
m1 max
are and look they've absolutely
surprised me a bit of a skeptic even
with their battery life and their
performance but i did two videos in my
real world test series i'll link those
below if you want to check that out
here i think we need to talk about the
bigger picture of what i think is
happening
and it starts with another company that
begins with a
arm first though mediatek one of the
largest arm chipset producers in the
world
with their arm chipsets in products that
you probably already own if we're honest
offered to help me make
this video and so with that said let's
talk about what arm is
and why it feels like a bunch of
companies are starting to make their
[Music]
chipsets
[Music]
okay let's first start off with who arm
is because it can get a little confusing
there's arm the company and there's arm
the processors which we'll get to
shortly the beginnings of arm the
company though
start with another company founded back
in 1983 in cambridge england called
acorn computers now at some time in the
mid 80s a team within that company was
charged with finding a suitable
processor for their next generation of
computer they went out looking but after
a while
they decided they couldn't find a
processor that fit the specs that they
needed
so over an 18 month period they ended up
designing their own fast forward to 1990
when acorn computers wasn't really doing
well financially as a computer
manufacturer
they spun out their processor designs
into a new company called advanced risk
machines limited
with apple and vlsi technology as
partners in the joint venture
apple used the new chipset in the newton
by the way then
in 1998 the company shortened its name
to arm
limited now arm doesn't actually make
chipsets they don't even have
manufacturing facilities instead they
simply own the design
of the chips and other related
intellectual property
and they license that out to other
manufacturers like say mediatek
for example but also apple samsung high
silicon which is huawei
qualcomm amazon microsoft you get the
point so that brings us to the next set
of questions we need to answer which is
what is an arm processor exactly what
makes it different
and again why is everybody seemingly
jumping on board
we have two major architectures used in
chipsets today
we have arm and then we have x86 which
is mainly used by
intel and a little bit by amd the
biggest difference between x86
and arm are the way they give
instruction sets or
it's the way that the program gives
instructions to the chipset at the
lowest level
the r in arm stands for risk which in
turn stands for
reduced instruction set computer and
while it is kind of a larger philosophy
about computing in general suffices to
say in this video
that it means that arm processors
require a much
smaller instruction set compared to x86
which can be given a much more complex
instruction set and then
use its own methods to parse everything
out and figure out how to go through it
all
think about like someone giving you a
to-do list arm would give you one task
at a time
and you would do it and come back to get
the next one task and then do that and
so on
whereas x86 would give you all of the
tasks at once and you'll go about
figuring out how to get them all done
now these two different ways of handling
instructions have their pros
and their cons on the one hand x86 and
their more complex instruction set can
handle more complex workloads
like that to-do list and figure out the
best way to handle all of the tasks
at once and it's why you still see it
being used at the highest end of
computers for the most part right now
on the other hand arm is a lot more
power efficient as it doesn't have to
use energy figuring out what to do with
the to-do list
what order to do the tasks in etc it
just gets instructions
gets it done with the energy needed and
comes back for the next one
this also means less heat is produced
which is why arm is the entire
mobile phone industry a use case that
needs better battery life and
obviously can't have a fan in it with
intel creating more efficient chipsets
lately and arm manufacturers creating
more and more powerful ones
both architectures which normally kind
of lived in their own
world are now competing for middle
ground but
there's one more big advantage to arm
processors and that's that
arm can actually license out the
architecture to manufacturers
who can then create their own custom
cores and tailor them specifically to
the use cases
that they need mediatek for example uses
this to create
chipsets that are purpose built for a
ton of custom use cases while also
keeping the cost down for manufacturers
and ultimately for consumers as well
devices like this two-in-one chromebook
uses mediatek's tablet optimize
mt-8183 chipset which has an eight-core
based cpu paired with an arm-based gpu
and has been customized for multimedia
playback
web browsing and other things you do on
a tablet
chromebook and even though it's a
chromebook with a touchscreen
that also comes included with a
detachable keyboard you can find it for
under 250 dollars brand new i'll leave
links below for anyone who's curious
about that
but also at the extremes of computing we
have the world's
smallest computer created by the
university of michigan
and is based on an arm cortex m0 plus
processor
and is smaller than a grain of rice on
the other end the world's most powerful
supercomputer as of april 2020 on the
top
500 which is a list of the 500 most
powerful computers updated twice a year
is the japanese fugaku which is also
based on the arm architecture
it hit 442 petaflops
that's 442 quadrillion floating point
operations
per second three times more than the
next
fastest computer on the list on top of
that it's also the 10th most power
efficient on that list
by performance per watt now this is the
first time that an arm processor has
ever taken the top spot on that list
but it just goes to show what a
manufacturer can do
when they're able to customize the
architecture for a very specific
task in this case trying to get the
highest benchmark score they could that
was used for the ranking
apple does this to the arm architecture
in their m1s to be more optimized at
running mac os
their own os on mac computers their own
computers
and companies like mediatek use arm
chipsets that they customize
and produce specifically for different
industries like iot and smart home
you know a lot of the amazon echo
devices that you have have their
chipsets in them
mobile phones like the lg velvet here in
the us
bluetooth speakers like this one from
jbl even chromebooks like we mentioned
earlier
and the list of things they make work
better by using customized arm
chips that's specific to their industry
and use case goes on
and on so the thing with either
processor
is that because they have different
instruction sets the ones made for one
will not work on the other instruction
set so
apps made for the vast majority of x86
programs like windows and mac
need to be reconfigured to then work on
arm processors and things on ios and
android that are on arm processors would
need to be redone to work on windows
or mac for example
now in the meantime in the computer
world where the vast majority of
processors are x86
companies like microsoft and apple have
created programs that
convert x86 code into code that the arm
processors can understand and that works
but it's
not optimal even apple lists rosetta too
their program meant to do this exact
thing as being quote
meant to ease the transition to apple
silicon giving you time to create a
universal binary for your app
it is not a substitute for creating a
native version of your app
end quote and i even did tests to show
how much of a difference a native app
has over a translated one and spoiler
it's a lot so for now this is a bit of a
downside for
arm chipsets that are being used in the
traditionally x86 space like mac
and pc but as more and more
manufacturers use arm chipsets in their
devices and then more
developers start to make their programs
optimized for
armed chipsets as there are more and
more of those devices
it'll become less and less of an issue
now even though intel is making more
efficient chipsets
it feels like to me that arm is moving
up
in performance faster than intel is
moving down in power consumption and
power efficiency and i for one am very
curious to see how intel
and amd boost their efforts to respond
to all of this
but the bigger thing for manufacturers
right now is the ability to customize
those chipsets to their specific
use cases and on top of the already
better battery life
and lower heat production so
manufacturers with the huge amount of
resources it takes to create
custom chipsets for their specific
devices
stand a benefit by getting more
performance for those devices for those
specific things that they need
to do there you go another decoder
episode
let me know what you guys think of this
video the format it did a little bit
different this time
curious what you guys think always
appreciate hearing you guys um also let
me know what you think of
arm chipsets and intel and amd and all
the other fun
fun things that are happening in the
chipset world always appreciate it
