over the past few years the two major
manufacturers of cpus
amd and intel have been using two very
different approaches
to how they designed their chips intel
has been offering more clock speed in
their cpus
now they're offering cpus with clock
speeds at five gigahertz across all
cores
well amd has been adding massive amounts
of cores
and threads to their processors so in
this video
we're going to take a look at clock
speed and see just how beneficial
it actually is since the 9900 ks
intel has started to offer cpus that can
be clocked at 5 gigahertz or higher
across all of their cores the clock
speed of a cpu
roughly translates to how many
instructions per second
that that cpu can process so if higher
clock speeds mean
faster computers why don't all cpus
offer this 5 gigahertz clock speed
well for one the clock speed really
isn't
all that goes into making a cpu faster
things like how many instructions
can be processed per clock cycle and how
those instructions are actually handled
tend to matter a lot more you can do
things like breaking up a single
instruction into multiple parts that can
be worked on simultaneously
or combining smaller instructions into
fewer operations so that they can all be
completed within fewer clock cycles
there is also a bit of a trade-off when
you push high clock speeds
if your clock speed is higher then the
cpu is going to consume
more power as well as generate more heat
and
heat is really difficult to dissipate
from
a cpu and another limitation is that you
cannot actually pack on
as many cores or threads as you would
normally have
in a high clock speed cpu because well
when you're packing all those cores
together and they start to get hot as
high clock speeds do
you're going to end up with a thermal
nightmare
this is why threadripper cpus for
example have pretty low clock speeds
with boost clocks that only go up to
about four gigahertz
and most other cpus their base clocks
are
much higher than that but the
threadrippers are able to offer
32 or even 64 cores in some cases
so these high-speed cpus are really
going to shine in applications where
a high core count isn't as necessary but
high clock speeds are
so that means things like graphic design
rendering
virtualization intense multitasking and
server processes
are all out but gaming on the other hand
gaming could be what carries these high
clock cpus
i mean after all gaming has such a high
influence on the pc marketplace
that's the primary reason why you see so
many cases that have a transparent side
panel
and computer parts that all have rgb led
lights on them
now most games aren't very cpu intensive
to begin with
they tend to rely more on the graphics
card than
anything else and the few games that are
cpu intensive
they usually don't benefit from a
processor that has
four or even more than eight cores
beyond that
the only thing you really get are
multitasking benefits say if you wanted
to
stream a game and have a web browser
open
at the same time that you're playing so
let's take a look at some benchmarks
to see how much of a difference clock
speed really makes
and credit for this video goes to the
youtube channel benchmark
who created these benchmarks with a
9900k
and an rtx 2080
are you doing this tier me
oh
[Applause]
oh
[Music]
there's some real speed in this race
anna we knew they were gonna bring it
this is the league we're going for here
come on guys
this is ours
okay eyes up we're heading downtown
expect trouble
hey we've got company on the right
coming up on the back let's see what
they got
[Music]
i think i know this cop uh
cute i'm serious he's bad news
we scored big on this one there's some
prime hunting here
so
you know when i found this photo of the
pacific ocean
i just knew for some reason that we were
going to go there in the end
all these rivers mountains deserts
they just won't do it's ocean or bust
i believed we could make it i did
i know i'll get there and if i need some
help
you will be there for me you will save
me again
won't you
artion please stop torturing yourself
it hurts to even look at you you and dad
too
it's not your dream and not his belief
in the occupying forces
it's just pain
yeah what's cracking
so in conclusion does clock speed
actually matter
not really in the majority of
applications a computer is used
that there are really no difference
between having a lower clock speed and a
higher clock speed
at least in the clock speeds that we see
on most consumer cpus
these days and there's a lot of
downsides to
the lower core count obviously if you
need to do things like rendering
virtualization any of those type of
workflows they're going to suffer
greatly from
that low core count gaming is the only
area where you're really going to notice
a difference
but even then the margins between four
and five gigahertz
are very small not to mention that
improvements
in the cpu architecture itself is going
to have
much more impact as we saw with the
recent amd
cpu and gpu launches because of things
like smart access memory
and rage mode a full amd setup is able
to outperform
intel and nvidia setups in most games
despite a lower clock speed
so hope you found this video useful
thanks for watching to the end
have a nice day
