ladies and gentlemen AMD has done it
again the Epic Bergamo
9754 crams 32 more cores into the
already well stuffed sp5 package of Epic Genoa for a total of a whopping
128 cores in the palm of my
hand or is it yes it is but I can
practically hear you guys furiously typing away lius who's going to spend
$122,000 on a CPU I'm never going to use
or even touch one of these monsters but here's the thing in the same way that
the Technologies from multi-million dollar Formula 1 cars trickle down
eventually to our daily drivers the advances that debut in high-end data
center chips almost inevitably make their way into your home PC and there is
a lot of goodness packed in here to be excited about and besides who cares if
you ever need one holy sh it's a 128
core CPU let's take this thing out for a rip rip like this segue to our sponsor
ODU a great business needs a great website so make yours for free with

or watch till the end of the video to learn more to achieve this level of core
stuffy AMD took the same impressive IO
die found on their epic Genoa CPUs that we met last year and they reworked the
ccds or core complex dieses for higher
density I will not be popping the lid
off of this thing to show you guys but if I did you would notice a couple of
key things first is that in spite of the higher core count there are actually
fewer ccds that's because instead of up
to 128 core D we're looking at 8 16 core
dies how on Earth did they pack them in so tight by using Zen 4C cores rather
than Reg regular Zen 4 cores now Zen 4C
is not like an Intel e or efficiency
core it should have the same performance per clock and the same level of feature
support just packed 1.5 squ mm tighter
each this means up to
256 cores in a 2p or two processor
server but it does come at a cost you lose some clock speed and you lose some
level three Cash which doesn't sound like a very good thing and is probably
the second thing you'd notice because in spite of having 33% more cores than
Genoa bergo ends up with only 66% as
much level three cash now AMD's argument for this is that in a cloud native
workload we're not expecting to overcommit core so it'll be less
impactful than you think but what even is a cloud native workload I'm so glad
you asked it's still a little vaguely defined but examples might be things you
use every day like search and social media and also tools you might not
realize you're using every day like software infrastructure and platform as
a service providers so in a way that makes sense since each workload is
likely to be contained to the core or maybe couple of cores that are allocated
to it without as much sharing of cached data across the CPU enough about that
though let's get this thing built starting with the motherboard which wow
if you are into motherboards this is a really sexy one as I mentioned already
bergo uses the same iio die as denoa which means there support for a whopping
12 channels of DDR 5cc memory and as
many as 128 Lanes of PCIe Gen 5 with a
single processor or up to 160 with a
dual processor setup and you can see evidence of that all over the ASRock
Genova -2t
x550 this thing is absolutely whistling with high-end features to the point
where in spite of it being a wider deep
Micro ATX form factor it doesn't even have room for everything that bergo has
to offer I mean it doesn't help that the sp5 socket plus the accompanying vrm
that can do anywhere from 360 to 400
watts of power delivery takes up about a quarter of the board let's go ahead and
get the CPU installed this is my first sp5 installed but on the surface it
looks pretty similar to what we've seen with pre AMD Threadripper and epic
processor so you lift up this carrier frame take out the cover man that is a
lot of freaking pins
6,096 really is that right that can't be
right go ahead and count him we go ahead and Slot that guy in a
little something like that really that's
it you don't even have to torque down the CPU does the pressure come from the
cooler yeah oh oh let's talk about that the reason
these server CPUs have so many more pins than a consumer one is because of all
the different endpoints that they need to be directly connected to and one of
the biggest mechanical challenges with these platforms is making sure that
every single one of them is contacting correctly because even one being missing
you could have a memory stick not show up or a PCIe slot that stops working
it's actually really common on Epic and thread rep builds especially if the
installer either doesn't torque the screws down enough or doesn't torque
them down in the right order as for the cooler we're using this is the xo4 sp5
it was sent over by Silverstone and it looks surprisingly wimpy considering
that it's cooling 128 CPU cores but
because the heat sources the cores are spread over such a large area under this
metal plate the IHS we don't have to
worry about the same kinds of concentrated hot spots that you might
see on something like an Intel 14900 K
that means even the heat pipes that aren't dead center on the cooler can
work much more efficiently and you can handle a 400 W CPU with a little thing
like this the instructions call for anywhere from 10.8 to 13 ftlb of torque
on each screw and for it to be tightened in a star pattern starting with the
sides and then doing the diagonals one after the other of course if you want to
be extra careful the best thing to do is start all the screws in that order and
then do a second pass checking all of the torque values with that out of the
way let's move on to the really cool stuff like RAM to help us take full
advantage of this platform Micron sent over 12 96 gig sticks of ddr5 5600 which
would give us a total of over a terabyte of memory if we could install all of
them but unfortunately due to limit ation of this
form factor we're only going to be able to put eight on it I know I'm as
disappointed as you guys are that we're slumming it with 768 gigs of RAM but you
know what I think we're going to be okay
see look it's not so bad 8 channels of memory I actually think azrock has done
a great job of maximizing the io given the limited space they're working with
we have four full fat PCIe gen 5x6 slots
down here so that's 64 of our lanes taken care of each of the larger mcio
connectors here is another eight Lanes two of them also support these eight
Port say a 6 gig breakout cables so that's 96 total now each of the m.2
slots that's another four lanes and the same goes for the different
MCI yeah this one right here so what's that 108 108 we're still 20 lanes shy
maybe they did need a bigger motherboard AMD has described epic as being as much
a PCIe switch as it is a CPU and they're
really not kidding they've crammed as many expansion ports as they possibly
could onto this board regardless of whether you'd actually be able to use
all of it and we've still got 20 more PCIe Gen 5 Lanes swinging in the breeze
we haven't even talked about the 8 PCI E gen 3 Lanes four of which are serving
our dual 10 gig Nicks and one more going to our as 2600 remote management system
that leaves three more Lanes just hanging out
no one no one down the street okay doesn't matter down the
street point is you toss in some minimal USB VGA port and we have a truly epic
amount of IO anyone I don't I don't get the
thing down the street I'm sorry we'll stop that now all that's left is to plug
in some storage and figure out our power situation see I have no doubt that this
15500 watt unit from Corsair can power the machine I'm just not sure sure how
we're going to connect it you see there's no 24 pin power connector on
here that would have taken up precious PCI Express and fan header space but
that's okay slowly but surely the industry is moving away from the lower
voltages that make up realistically most of the pins in a 24 pin connector and
two 12vt only designs so what we've got
instead is three 8 pin ATX CPU power
connectors and then this tiny little four pin that takes an adapter off of
your 24 pin just for the power switch that's the green and black one right
here power okay and then 5vt standby
which is going to allow you to wake the system with a USB device for example now
I can practically hear you thinking wow that power supply is being comically
underutilized but don't worry guys we're going to find something power hungry to
plug into it that's foreshadowing but
first putting this thing on a test bench feels like a bit of a disservice doesn't
it I think we need need a case and I think I know just the
one oh you're not getting that run are you dang
it oh God what oh God this is awesome I
give me a hand at this oh boy oh how much do the wheels cost surprisingly
nothing they were included what is this
okay this this is a piece of History the
year was 2003 I had a lot less facial
hair and had never experienced gaming on
a dedicated GPU there's no clip for it YouTube
hadn't been invented yet but AMD existed
and was announcing their first fora into the workstation and server market up on
this was also our first look at the 64-bit instruction set extension to x86
that Intel would ultimately license and is still in use to this day AMD wanted
to make a splash for the launch so they held an event down in in Texas and
showed off a dozen prototype optron systems in everything from single CPU to
eight CPU configurations all in cases
just like this one complete with
included wheel lock I love this pull out drawer too remember kitchy 5 and a/4 in
devices this one's a speaker anyway
after the event the systems were decommission so a bunch of them ended up
being sold in a San Antonio computer store at least one ended up on eBay and
several more were simply scrapped this one though was bought by fellow YouTuber
Wolfman mods who put it in storage for several years before it eventually made
its way up here now we've cleaned it up as much as we dare to but we don't
really want to damage something so unique now this case not exactly
designed for ATX motherboards but it's so big we can just toss our test bench
inside it I think Perfection complete completely toolless installation oh
other than the side panel but for that all we need is a quarter turn with our
trusty LT screwdriver this is so janky how did
they think this was a good idea how unexpected a graphics card haha hey
we're booted 768 gigs of RAM and enough logical
processors that it looks like a quad socket machine from just a couple of
years ago did you see how how long that took
to loan look at this list what this is
absolutely mindblowing I mean okay it's
only running at 1.8 GHz right now but 73
7 75 Watts that seems pretty reasonable
AMD's Radion division could take some notes they have desktop gpus that
consume that at idol here we go how fast
will this go remember guys this is R23
not the older R20 this should put the burn
on are you freaking kidding
me one chip one chip it barely even
managed to spool up we touched 235 Watts
for 5 seconds maybe it was a fluke yeah
yeah yeah maybe it was a fluke maybe it was a fluke try we'll try again we'll try
again is it done right yeah I'd say
maybe 2/3 of the core is actually got to 100 holy crap the rest just sat there
like 70 wait we might not actually be
using enough cores custom number of render threads
256 can it go even faster than
86,000 points it might have been using 256 it might just not have fully spooled
up oh yeah there goes all your cores
holy crap I think that was even 89,000 points guys context here okay a
Threadripper 20 990 WX K that's a 32
core chip is left completely in the dust
but that's okay because Maxon has a new generation of cine bench
r24 let's see if that can bring this monster to its knees I haven't actually
used this before it looks like it visually represents what's going on a
little bit differently and it has all cores working on small chunks at a time
rather than each core working on a tiny tiny tiny little chunk now let's have a
look at clock speeds are highest boosted core is just over 3 GHz most of them are
in the 2.6 to 2.8 range though oh wait
no I lied there's a bunch over here that
are at 3.1 oh my goodness it's kind of all over the place now I want to look at
clock speed we've got more course than I was expecting boosting all the way to
the maximum of 3.1 gahz but most of them
are somewhere in the 2.8 to
2.93 GHz range that makes sense remember
how we talked about these zen4 C cores being more tightly packed than regular
Zen 4 course that's why our Max boost is
just 3.1 GHz on this chip but that
reduced clock speed means that this bergo part shares the same default TDP
of 360 Watts with the Genoa chip before
it in spite of the 32 additional course
plus as served the home found in there testing Bergamo can comfortably run with
all 128 cores boosting for hours on end
without neighboring cores interfering with each other maybe we need to do a
quick pie calculation oh hold on first cinebench is done and we are about four
times the speed of an apple M1 Ultra
that is that's a fast chip guys it's not like yeah but whatever it's Apple that's
a really fast CPU now it's time for more delicious Benchmark using Y cruncher
will'll be calcul culting pi to oh I
don't know 250 billion decimal places how much
round do we have S about right we got a terabyte oh no we don't have a terabyte
crap we have 768 oh sorry guys it'll have to be a 100 billion decal decimal
places watch this memory usage
go they are not turboing as high in this
workload that tells us that this is a more demanding workload and we could be
somewhat power limited or VM limited I don't think it's going to be power only
a little over 300 watts could even be thermals though we managed to hit
82° on average mind you that's the higher averaged die reading the actual
ccds themselves where the compute is happening are all in the 55
range kind of incredible when you consider how much heat is blowing off
the back of this but that's what having a more spread out heat load will do for
you wait we can check this we are thermal throttling oh crud we're not
getting nearly as much performance out of this CPU as we should H is there
anything we can do about that right now okay hear me out we missed the fins of
the heat sink that's actually a terrible idea it
would probably work do we have a spray bottle full of
alcohol you can make some alcohol interesting
interesting interesting oh God okay hold
on hold on let me just this is how fire is made kids no no no no no no no no no
there's not going to be a fire there's not going to be a fire okay hold on this is the dumbest thing I've ever done it's
close buddy it's close I need actual
water though no you can't spray water Don't Spray water can't sounds like a
challenge to me I've got a shield here
on the back side so none of the water will end up where it's not supposed to
be okay let's see if uh let's see if
that'll help it hey hey look at this CPU
power consumption 300 WS almost I don't really think it's
working realistically then we're not going to get a representative reading
given that we don't have an adequate cooler and this is the only cooler we
have for this socket so why don't we move on to a load that's not going to
stress the entire CPU like a video game
come on you guys you knew we were going to do it go we had to do it
video oh where's our FP what oh no 50
frames per second I mean we oh man that's why that's why I
got shot there are you kidding me
something I want to clarify is there's nothing architecturally about this CPU
that makes it bad at running games I've seen it so many times in the comments oh
is using a server CPU to run games especially when we'll do for example
older generation Zeon builds as kind of cheap and cheerful gaming rigs but that
is not the case at all this is the same
as any other Zen 4 core except that it's running at such a low clock speed that
it's just not able to keep up with our poor 490 that's
like wants to go it wants to go but it
can't go oh crap wow human that guy was
terrible no offense buddy but wow we're
using 96 W this this is just not working
guys I've also got another game to try's see if something a little bit more
multi-threaded is going to do better now that's more like it over 200 frames per
second clearly there is something about CS2 that does not like having a slow CPU
I mean we know it runs way faster with a faster one but I was not expecting it to
be that bad yeah we're getting 180 FPS
I'm only at 1080p mind you but if we had a CPU bottleneck we should be quite CPU
bottleneck regardless of the resolution we're running at I mean this is a 4090
so that's not going to hold us back CPU usage is at
0% oh then it goes up to 25 uh then back
to zero what what what are you even talking about you know what it doesn't
matter the reality is nothing we run here is a real test of what these chips
are capable of or what they're designed for and prepackaged benchmarks for cloud
workloads are few and far between with most customers for a product like this
either being the kinds of folks who build data Centric capacity then lease
it to third party and let the customers figure out the rest or the kinds that
operate at such a large scale that they would expect to receive samples from
either AMD or their own budgets that they would use to optimize their
workloads and evaluate the suitability based on real world testing and honestly
seems like things are going pretty well for AMD on both fronts with their
massive lead in core counts and PCIe iio
everyone from Microsoft and meta to Amazon and Google is building up
infrastructure around bergam Mo and other epic CPUs and with Intel's Sierra
Forest response using stripped down efficiency cores and being as much as 8
months away it doesn't look like that's going to be changing in the near future
so opteron might have ultimately fizzled
out but epic looks poised to continue making massive gains in the data center
well at least until the competition from ARM-based competitors gets even stronger
strong like my segue game to our sponsor
