this is the fastest CPU on the planet it costs
$8,000 has 64 cores and18 threads 128
Lanes of PCI Express Gen 4 and runs on AMD's latest 7 nanm Zen 3 architecture
that's the same one powering their top-of-the-line 5000 series ryzen gaming
CPUs its code name is epic Milan and we
have two of them thanks to our buddy Wendell over at level one let's take
them for a spin cuz holy they ever
fast hey this is the topof the line 's and G's the Epic 7763 that I'm holding
in my hand yeah it may only run at a mere 2.45 GHz base 3.5 gahz boost but
don't let that fool you this ain't no Civic okay this is the Hummer with the
Swap all right these things are huge I can't get
over it pretty big why do they have to make them so big it's not a measuring
contest just never gets old you know I think the only way to get a bigger one
is to buy one on LTT Store.com oh yeah by the way we're going to have epic
Threadripper shaped ones coming soon probably in a few months now of course
Yoda would happily remind all of us that size not important performance is what
matters and when it comes to Performance this is pretty much the finest display
of kicking someone while they're down that I think I have ever seen and I
don't even feel bad here's the thing Intel's latest and greatest 10 nmet ice
Lake xeons they've got some platform advantages particularly when they're
paired with Intel's optain memory but for purely CPU bound applications I mean
they're not even competitive with AMD's last generation epic RAM chips price for
price let alone the the new ones cuz here's the thing AMD comes in with more
cores more gigahertz more cash and
literally double the PCI Express Lanes
per socket yet AMD still prices their
top dog cheaper than Intel's Top Dog and you might think well at $8,000 a chip
200 bucks that's a that's a rounding error right but if you're buying a, of
them at a time like Intel thinks you are
sorry Intel not good enough for you I guess that works out to a qu million
dollar not to mention that if you're an Enterprise or a data center that's
upgrading your systems from say last gen on Intel you're going to need a whole
new motherboard which for servers generally means an entirely new system
complete with financing and warranty how about the warranty like if something
goes wrong either with the hardware or software AMD by contrast allows you to
Simply swap out the CPU update your BIOS
preferably in the other order and you're good to go they've actually been using
the exact same socket for their server platforms ever since the original epic
launched back in 2017 and this intercompatibility is fantastic you know
how I know because this is the exact
same motherboard that we used to build our PC Mac Pro killer with our last gen
epic something to note before we go any further is that server components are
generally designed to be run in an extremely high airflow environment so
this cooling if that doesn't look suitable for a nearly 300 W CPU that's
cuz it's not we need to get need to get a fan on there let's just throw m.2 in
here this is by the way the greatest thing ever this little toolless m.2
retention mechanism absolutely love it
they should all have that this supreme x390 is so hilarious it's so big we've
never even tried to integrate it into an actual build it's test bench use only
now you might notice that I'm installing it in one of the bottom PCI Express l
normally I would say don't do that but epic has so many PCI Express Lanes that
every one of these 16x slots all the M do2s all of it is just running full fat
PCIe Gen 4 with all the lanes so just doesn't matter okay okay I shouldn't
quite say it doesn't matter there are situations where the lanes might need to
be reallocated and there the different chiplets and where they're attached to
the io die and all that but mostly it's
fine W there it goes 128 threads guys
this is C bench R23 this isn't the like
weak easy one now the reason that it was
so easy TM for AMD to maintain
compatibility across Generations is that under the hood the layout of their Milan
CPUs is nearly identical to their older
Rome predecessors but that's not to say that AMD didn't change anything like
other zen3 CPUs each of the eight
chiplets here which each contains eight course gets a full 32 Megs of cash that
is completely accessible to all eight of the cores rather than being split into
16 Megs and 16 Megs that means more efficient use of resources and lower
latency they've also increased the speed of the infinity fabric links within the
CPU and they've made a ton of other under thee Hood architectural changes
that have allowed AMD to hit a surprising 19% average IPC uplift that
means that clock for clock this thing is almost 20% faster oh and they upped the
maximum TDP for many of their chips including the 7763 to allow up to 280
watts per socket I mean that is how you get stuff like this happening look where
it sits relative to anything else in the data base
61,000 what so while the CPU is is running a heavy Benchmark like this it's
self-reporting a peak of around 277 278
watts of power what that means is that according to wendle from level one Tex
this Tian board we have here is actually a bit on the conservative side for power
delivery the Daytona reference chassis that we've got back here can actually do
closer to 285 290 watts per socket with some power
tweaks which actually sounds a lot like AMD has some over clocking Headroom here
you can even tweak some IO settings like disabling PCI Express Gen 4 or lowering
your memory speeds to give a bit more of the CPU's power budget to the course
themselves potentially improving performance but then again slowing down
your PCI Express Lanes or lowering your memory bandwidth can also hurt
performance in other ways so it's going to depend on your application either way
I cannot freaking wait to see what zen3
based Threadripper is going to be like especially with the core clocks and the
power limits unlocked as we assume they'll be I suspect we're going to need
some new motherboards with new power delivery for
those now let's have some more fun last time around with our Rome based 64 core
epic blender was only able to use half of the cores per instance so we ran it
twice with both of them running at the same time finishing in around a minute
and 14 seconds this time around we are
having no trouble utilizing the entire CPU and you can see I mean just look at
this thing it is absolutely crushing this Benchmark and
the craziest part is check out these boost clocks we are seeing an excess of
2.8 GHz even as high as 3.1 GHz on some
of these cores as it's running through this blender
render and what's interesting is our temps are so well under control the
maximum we've seen so far after about 10
minutes of cin bench running continuously and blender is around 70°
super reasonable the fans aren't even ramping up it's almost like having a
gigantic CPU with the cores all spread out helps to get rid of the heat almost
if you can't wait for the next Threadripper and you decided you're crazy enough to use this as a workstation
check this out I'm running this at half quality in the preview here this is an
8K timeline with multiple 8K Clips
obviously there's a bunch of lumry color being applied to it look how smooth that
is it's butter smooth can we make it all the way to full man that scrubbing is
still extremely responsive naturally our next order of
business is to play video games on it we got a Apex Legends running at a cool 144
FPS average that sounds not too bad maxed out at 4K I don't have any
ammo that's okay it's not about being good at the game it's about having a
good computer to run the game right so we got f12020 going here and what I did
is I reset the hardware info clock speed
logger so I want to see just how high these cores will get this is a game that
unlike Apex Legends can actually make use of heavily heavily multicore CPUs so
we're going to go ahead and uh okay there we go that's more like it
now we're oh yeah we're driving now we're driving 1% lows at around 150 FPS
according to frame view over here so can you game on an epic server yes you you
can ah I need to break I'm broken once
again the point is not how good I am at the game the point is this thing is sick
oh I crashed so max we managed to hit
3.5 GHz in games and yes of course we're
going to play Crisis 3 it is kind of amazing how good this game still looks
is it not freaking Crisis 3 even your hand model like looks really good yep
it's amazing how well this game has aged
it's running at about 60 FPS at 4K you know this is a really quiet server MH
I'm impressed uh you know I think it
might be a little misleading all right here it goes 264
core epics cin bench R23 sorry sorry
Riley it's like 120 watts of fans yeah
yeah it's really fast though what the
hell holy crap c b oh okay let's are you
just going to tease me like that it ran in 12 seconds I want to see task manager
takes longer to queue up the test than it takes to run the test hold on I'm not
even going to be able to get it up in time dang it
91,000 what that's weak it should be able to do like
110 really yeah oh all right new attempt
Wendell sent us over a couple tuning parameters here we
go 98 623 that's not quite the 100K plus
that Wendell managed to get on his own with more tinkering and more tuning but
I think it goes to show a couple of things number one is these things are so
fast they can tear through anything not made for gaming who cares they're going
to game pretty good and number two is that once you get to this level of
Hardware it's not just plug andplay ladies and gentlemen you actually have
to know what the freak you're doing can you imagine running like 16 quad core
virtualized gaming stations off of one of these like uh maybe in our land
Center get subscribed to make sure you don't miss that and while you're down
there let us know if you have any other cool ideas for a project we could use
one of these bad boys for just like I'm going to let you know what you could use
