WEBVTT

00:00:00.280 --> 00:00:09.960
this is the fastest CPU on the planet it costs

00:00:05.080 --> 00:00:12.639
$8,000 has 64 cores and18 threads 128

00:00:09.960 --> 00:00:18.400
Lanes of PCI Express Gen 4 and runs on AMD's latest 7 nanm Zen 3 architecture

00:00:16.800 --> 00:00:26.000
that's the same one powering their top-of-the-line 5000 series ryzen gaming

00:00:21.199 --> 00:00:28.000
CPUs its code name is epic Milan and we

00:00:26.000 --> 00:00:35.920
have two of them thanks to our buddy Wendell over at level one let's take

00:00:30.640 --> 00:00:35.920
them for a spin cuz holy they ever

00:00:41.879 --> 00:00:50.360
fast hey this is the topof the line 's and G's the Epic 7763 that I'm holding

00:00:47.680 --> 00:00:57.280
in my hand yeah it may only run at a mere 2.45 GHz base 3.5 gahz boost but

00:00:55.199 --> 00:01:01.680
don't let that fool you this ain't no Civic okay this is the Hummer with the

00:01:00.160 --> 00:01:06.159
Swap all right these things are huge I can't get

00:01:04.040 --> 00:01:10.520
over it pretty big why do they have to make them so big it's not a measuring

00:01:07.960 --> 00:01:14.720
contest just never gets old you know I think the only way to get a bigger one

00:01:12.040 --> 00:01:18.600
is to buy one on LTT Store.com oh yeah by the way we're going to have epic

00:01:16.720 --> 00:01:24.000
Threadripper shaped ones coming soon probably in a few months now of course

00:01:21.119 --> 00:01:30.320
Yoda would happily remind all of us that size not important performance is what

00:01:27.439 --> 00:01:35.960
matters and when it comes to Performance this is pretty much the finest display

00:01:33.520 --> 00:01:40.520
of kicking someone while they're down that I think I have ever seen and I

00:01:38.159 --> 00:01:44.960
don't even feel bad here's the thing Intel's latest and greatest 10 nmet ice

00:01:42.840 --> 00:01:49.479
Lake xeons they've got some platform advantages particularly when they're

00:01:46.600 --> 00:01:55.479
paired with Intel's optain memory but for purely CPU bound applications I mean

00:01:52.920 --> 00:02:01.039
they're not even competitive with AMD's last generation epic RAM chips price for

00:01:58.479 --> 00:02:08.200
price let alone the the new ones cuz here's the thing AMD comes in with more

00:02:03.960 --> 00:02:11.200
cores more gigahertz more cash and

00:02:08.200 --> 00:02:14.280
literally double the PCI Express Lanes

00:02:11.200 --> 00:02:16.680
per socket yet AMD still prices their

00:02:14.280 --> 00:02:21.560
top dog cheaper than Intel's Top Dog and you might think well at $8,000 a chip

00:02:19.560 --> 00:02:27.319
200 bucks that's a that's a rounding error right but if you're buying a, of

00:02:24.280 --> 00:02:29.080
them at a time like Intel thinks you are

00:02:27.319 --> 00:02:33.840
sorry Intel not good enough for you I guess that works out to a qu million

00:02:32.000 --> 00:02:37.920
dollar not to mention that if you're an Enterprise or a data center that's

00:02:35.480 --> 00:02:42.319
upgrading your systems from say last gen on Intel you're going to need a whole

00:02:39.920 --> 00:02:46.599
new motherboard which for servers generally means an entirely new system

00:02:44.519 --> 00:02:50.080
complete with financing and warranty how about the warranty like if something

00:02:48.120 --> 00:02:56.440
goes wrong either with the hardware or software AMD by contrast allows you to

00:02:53.080 --> 00:02:58.920
Simply swap out the CPU update your BIOS

00:02:56.440 --> 00:03:02.480
preferably in the other order and you're good to go they've actually been using

00:03:00.560 --> 00:03:06.599
the exact same socket for their server platforms ever since the original epic

00:03:04.519 --> 00:03:12.560
launched back in 2017 and this intercompatibility is fantastic you know

00:03:09.519 --> 00:03:14.319
how I know because this is the exact

00:03:12.560 --> 00:03:19.159
same motherboard that we used to build our PC Mac Pro killer with our last gen

00:03:17.319 --> 00:03:23.280
epic something to note before we go any further is that server components are

00:03:21.319 --> 00:03:29.280
generally designed to be run in an extremely high airflow environment so

00:03:26.879 --> 00:03:35.400
this cooling if that doesn't look suitable for a nearly 300 W CPU that's

00:03:33.040 --> 00:03:39.319
cuz it's not we need to get need to get a fan on there let's just throw m.2 in

00:03:37.640 --> 00:03:44.920
here this is by the way the greatest thing ever this little toolless m.2

00:03:41.879 --> 00:03:47.640
retention mechanism absolutely love it

00:03:44.920 --> 00:03:52.560
they should all have that this supreme x390 is so hilarious it's so big we've

00:03:50.680 --> 00:03:57.560
never even tried to integrate it into an actual build it's test bench use only

00:03:55.640 --> 00:04:02.599
now you might notice that I'm installing it in one of the bottom PCI Express l

00:04:00.120 --> 00:04:08.400
normally I would say don't do that but epic has so many PCI Express Lanes that

00:04:05.680 --> 00:04:14.280
every one of these 16x slots all the M do2s all of it is just running full fat

00:04:11.439 --> 00:04:18.199
PCIe Gen 4 with all the lanes so just doesn't matter okay okay I shouldn't

00:04:16.320 --> 00:04:23.080
quite say it doesn't matter there are situations where the lanes might need to

00:04:20.320 --> 00:04:28.720
be reallocated and there the different chiplets and where they're attached to

00:04:25.240 --> 00:04:34.520
the io die and all that but mostly it's

00:04:28.720 --> 00:04:37.680
fine W there it goes 128 threads guys

00:04:34.520 --> 00:04:42.199
this is C bench R23 this isn't the like

00:04:37.680 --> 00:04:45.240
weak easy one now the reason that it was

00:04:42.199 --> 00:04:47.360
so easy TM for AMD to maintain

00:04:45.240 --> 00:04:53.680
compatibility across Generations is that under the hood the layout of their Milan

00:04:50.039 --> 00:04:56.280
CPUs is nearly identical to their older

00:04:53.680 --> 00:05:01.759
Rome predecessors but that's not to say that AMD didn't change anything like

00:04:58.680 --> 00:05:03.759
other zen3 CPUs each of the eight

00:05:01.759 --> 00:05:10.240
chiplets here which each contains eight course gets a full 32 Megs of cash that

00:05:07.479 --> 00:05:15.199
is completely accessible to all eight of the cores rather than being split into

00:05:12.440 --> 00:05:20.479
16 Megs and 16 Megs that means more efficient use of resources and lower

00:05:17.639 --> 00:05:25.639
latency they've also increased the speed of the infinity fabric links within the

00:05:22.680 --> 00:05:28.560
CPU and they've made a ton of other under thee Hood architectural changes

00:05:27.240 --> 00:05:34.919
that have allowed AMD to hit a surprising 19% average IPC uplift that

00:05:32.680 --> 00:05:41.360
means that clock for clock this thing is almost 20% faster oh and they upped the

00:05:38.919 --> 00:05:48.520
maximum TDP for many of their chips including the 7763 to allow up to 280

00:05:45.680 --> 00:05:53.400
watts per socket I mean that is how you get stuff like this happening look where

00:05:50.639 --> 00:05:59.759
it sits relative to anything else in the data base

00:05:56.880 --> 00:06:05.919
61,000 what so while the CPU is is running a heavy Benchmark like this it's

00:06:01.440 --> 00:06:08.520
self-reporting a peak of around 277 278

00:06:05.919 --> 00:06:12.479
watts of power what that means is that according to wendle from level one Tex

00:06:10.560 --> 00:06:17.039
this Tian board we have here is actually a bit on the conservative side for power

00:06:14.680 --> 00:06:20.599
delivery the Daytona reference chassis that we've got back here can actually do

00:06:19.199 --> 00:06:27.759
closer to 285 290 watts per socket with some power

00:06:24.840 --> 00:06:33.199
tweaks which actually sounds a lot like AMD has some over clocking Headroom here

00:06:31.000 --> 00:06:37.880
you can even tweak some IO settings like disabling PCI Express Gen 4 or lowering

00:06:35.840 --> 00:06:41.440
your memory speeds to give a bit more of the CPU's power budget to the course

00:06:39.840 --> 00:06:46.720
themselves potentially improving performance but then again slowing down

00:06:44.319 --> 00:06:50.160
your PCI Express Lanes or lowering your memory bandwidth can also hurt

00:06:48.440 --> 00:06:55.599
performance in other ways so it's going to depend on your application either way

00:06:52.520 --> 00:06:57.400
I cannot freaking wait to see what zen3

00:06:55.599 --> 00:07:01.479
based Threadripper is going to be like especially with the core clocks and the

00:06:59.599 --> 00:07:04.599
power limits unlocked as we assume they'll be I suspect we're going to need

00:07:03.000 --> 00:07:09.080
some new motherboards with new power delivery for

00:07:06.599 --> 00:07:14.280
those now let's have some more fun last time around with our Rome based 64 core

00:07:11.840 --> 00:07:19.280
epic blender was only able to use half of the cores per instance so we ran it

00:07:16.919 --> 00:07:24.039
twice with both of them running at the same time finishing in around a minute

00:07:20.800 --> 00:07:26.199
and 14 seconds this time around we are

00:07:24.039 --> 00:07:30.879
having no trouble utilizing the entire CPU and you can see I mean just look at

00:07:28.520 --> 00:07:36.400
this thing it is absolutely crushing this Benchmark and

00:07:34.400 --> 00:07:43.360
the craziest part is check out these boost clocks we are seeing an excess of

00:07:39.319 --> 00:07:45.360
2.8 GHz even as high as 3.1 GHz on some

00:07:43.360 --> 00:07:49.199
of these cores as it's running through this blender

00:07:46.520 --> 00:07:55.199
render and what's interesting is our temps are so well under control the

00:07:51.919 --> 00:07:56.520
maximum we've seen so far after about 10

00:07:55.199 --> 00:08:03.080
minutes of cin bench running continuously and blender is around 70°

00:08:00.560 --> 00:08:07.000
super reasonable the fans aren't even ramping up it's almost like having a

00:08:04.840 --> 00:08:11.400
gigantic CPU with the cores all spread out helps to get rid of the heat almost

00:08:10.000 --> 00:08:17.159
if you can't wait for the next Threadripper and you decided you're crazy enough to use this as a workstation

00:08:14.360 --> 00:08:22.080
check this out I'm running this at half quality in the preview here this is an

00:08:19.080 --> 00:08:23.919
8K timeline with multiple 8K Clips

00:08:22.080 --> 00:08:29.639
obviously there's a bunch of lumry color being applied to it look how smooth that

00:08:27.080 --> 00:08:35.200
is it's butter smooth can we make it all the way to full man that scrubbing is

00:08:32.640 --> 00:08:39.599
still extremely responsive naturally our next order of

00:08:37.399 --> 00:08:46.279
business is to play video games on it we got a Apex Legends running at a cool 144

00:08:43.680 --> 00:08:51.240
FPS average that sounds not too bad maxed out at 4K I don't have any

00:08:48.680 --> 00:08:54.959
ammo that's okay it's not about being good at the game it's about having a

00:08:52.640 --> 00:09:01.200
good computer to run the game right so we got f12020 going here and what I did

00:08:58.160 --> 00:09:03.360
is I reset the hardware info clock speed

00:09:01.200 --> 00:09:07.320
logger so I want to see just how high these cores will get this is a game that

00:09:04.839 --> 00:09:14.240
unlike Apex Legends can actually make use of heavily heavily multicore CPUs so

00:09:11.480 --> 00:09:19.240
we're going to go ahead and uh okay there we go that's more like it

00:09:16.640 --> 00:09:26.320
now we're oh yeah we're driving now we're driving 1% lows at around 150 FPS

00:09:24.240 --> 00:09:34.079
according to frame view over here so can you game on an epic server yes you you

00:09:29.560 --> 00:09:36.160
can ah I need to break I'm broken once

00:09:34.079 --> 00:09:41.920
again the point is not how good I am at the game the point is this thing is sick

00:09:38.480 --> 00:09:45.800
oh I crashed so max we managed to hit

00:09:41.920 --> 00:09:48.480
3.5 GHz in games and yes of course we're

00:09:45.800 --> 00:09:54.160
going to play Crisis 3 it is kind of amazing how good this game still looks

00:09:51.360 --> 00:10:01.079
is it not freaking Crisis 3 even your hand model like looks really good yep

00:09:56.600 --> 00:10:04.000
it's amazing how well this game has aged

00:10:01.079 --> 00:10:09.600
it's running at about 60 FPS at 4K you know this is a really quiet server MH

00:10:06.440 --> 00:10:11.079
I'm impressed uh you know I think it

00:10:09.600 --> 00:10:20.000
might be a little misleading all right here it goes 264

00:10:15.360 --> 00:10:23.839
core epics cin bench R23 sorry sorry

00:10:20.000 --> 00:10:27.360
Riley it's like 120 watts of fans yeah

00:10:23.839 --> 00:10:31.959
yeah it's really fast though what the

00:10:27.360 --> 00:10:33.560
hell holy crap c b oh okay let's are you

00:10:31.959 --> 00:10:38.680
just going to tease me like that it ran in 12 seconds I want to see task manager

00:10:36.680 --> 00:10:42.279
takes longer to queue up the test than it takes to run the test hold on I'm not

00:10:41.079 --> 00:10:47.399
even going to be able to get it up in time dang it

00:10:44.680 --> 00:10:52.360
91,000 what that's weak it should be able to do like

00:10:48.600 --> 00:10:54.240
110 really yeah oh all right new attempt

00:10:52.360 --> 00:10:57.240
Wendell sent us over a couple tuning parameters here we

00:10:57.480 --> 00:11:03.839
go 98 623 that's not quite the 100K plus

00:11:02.200 --> 00:11:08.279
that Wendell managed to get on his own with more tinkering and more tuning but

00:11:06.519 --> 00:11:12.560
I think it goes to show a couple of things number one is these things are so

00:11:10.240 --> 00:11:16.959
fast they can tear through anything not made for gaming who cares they're going

00:11:14.600 --> 00:11:20.839
to game pretty good and number two is that once you get to this level of

00:11:18.720 --> 00:11:24.880
Hardware it's not just plug andplay ladies and gentlemen you actually have

00:11:22.519 --> 00:11:31.560
to know what the freak you're doing can you imagine running like 16 quad core

00:11:29.519 --> 00:11:35.760
virtualized gaming stations off of one of these like uh maybe in our land

00:11:33.920 --> 00:11:39.240
Center get subscribed to make sure you don't miss that and while you're down

00:11:37.680 --> 00:11:43.959
there let us know if you have any other cool ideas for a project we could use

00:11:41.120 --> 00:11:49.200
one of these bad boys for just like I'm going to let you know what you could use

00:11:45.320 --> 00:11:52.079
our sponsor for ting mobile sponsored

00:11:49.200 --> 00:11:56.480
today's video and they want you to hear their message over the sound of these

00:11:53.760 --> 00:12:00.240
fans you can save by switching to Ting that's right they've got unlimited talk

00:12:37.839 --> 00:12:45.120
out oh we had a lot of fun building an ITX 64 core build with our Rome

00:12:43.199 --> 00:12:48.600
equivalent to this CPU that thing was Tiny powerful
