00:00:00.000 --> 00:00:05.920
now the whole industry has been really excited about how AMD's 3rd gen ryzen

00:00:03.840 --> 00:00:12.240
processors have finally caught up to Intel in key consumer applications like

00:00:08.960 --> 00:00:14.880
gaming but in the background AMD has

00:00:12.240 --> 00:00:20.880
been quietly not just catching up to Intel but surpassing them by an

00:00:18.000 --> 00:00:25.600
incredible margin with their second generation of epic

00:00:23.279 --> 00:00:34.840
server processors and in my hands i have the epic rom 7742

00:00:31.359 --> 00:00:39.120
a 64 core

00:00:34.840 --> 00:00:42.640
128 thread eight channel memory absolute

00:00:39.120 --> 00:00:45.760
monster of a CPU welcome to

00:00:42.640 --> 00:00:48.160
today's episode of holy sh

00:00:45.760 --> 00:00:52.160
where we are gonna take this thing for a little test drive guys the full review

00:00:50.320 --> 00:00:56.160
will come make sure you're subscribed so you don't miss that but today is going

00:00:53.840 --> 00:00:59.280
to be more about the stuff that AMD didn't want to see us a processor

00:00:57.760 --> 00:01:02.640
because they knew we were gonna do like running cinebenching games and all that

00:01:00.879 --> 00:01:07.040
kind of fun stuff speaking of fun this segue to our

00:01:04.400 --> 00:01:11.439
sponsor glasswire with glasswire you can see what's going in and out of your pc

00:01:09.760 --> 00:01:16.000
over its network connection so you can diagnose if there's any suspicious apps

00:01:13.840 --> 00:01:21.470
behaving badly so check it out and get 25 off using offer code Linus at the

00:01:18.880 --> 00:01:26.430
link in the video description

00:01:29.439 --> 00:01:40.159
so while we get set up here i want to fill you guys in on some of what's special about AMD's epic roam platform

00:01:35.439 --> 00:01:44.159
so as i mentioned before this is a 77 42

00:01:40.159 --> 00:01:46.880
with 64 cores and 128 threads but

00:01:44.159 --> 00:01:50.560
contrary to what you might think if your only CPU experience is with Intel

00:01:49.360 --> 00:01:56.799
processors even though it has 64 cores in it its

00:01:54.280 --> 00:02:01.520
225 watt TDP is not

00:01:58.159 --> 00:02:03.920
actually that much higher than Intel's

00:02:01.520 --> 00:02:06.960
top of the line server chips which only have a mirror

00:02:07.280 --> 00:02:15.440
it's hard to wrap my brain around saying that a mere 28 course on board and the

00:02:13.040 --> 00:02:21.599
unfairness of this comparison doesn't end at the core counts and the thermals

00:02:18.080 --> 00:02:24.239
at the top end AMD boasts nearly seven

00:02:21.599 --> 00:02:29.920
times the cash four times the maximum memory capacity two extra memory

00:02:26.720 --> 00:02:32.080
channels pci express gen four which is

00:02:29.920 --> 00:02:38.959
double the speed of gen three not to mention that they've got nearly three

00:02:35.200 --> 00:02:41.440
times as many lanes on board and

00:02:38.959 --> 00:02:47.440
they come in at four thousand dollars less and that's just at

00:02:44.400 --> 00:02:50.480
the top end up and down the stack

00:02:47.440 --> 00:02:54.080
Intel's xeon scalable processors are

00:02:50.480 --> 00:02:55.680
under attack from AMD epic rome and it

00:02:54.080 --> 00:03:00.879
gets better than that so a little over 15 years ago AMD made a huge step

00:02:58.800 --> 00:03:04.400
forward in computer architecture by taking the memory controller off of the

00:03:03.440 --> 00:03:11.440
north bridge that that second chipset that motherboards used to have on them and

00:03:08.159 --> 00:03:14.000
integrating it into the CPU now

00:03:11.440 --> 00:03:19.120
they've done themselves one further by taking nearly everything that still

00:03:16.640 --> 00:03:23.440
existed whether you want to call it a a chipset or an i o hub or whatever else

00:03:21.519 --> 00:03:29.519
but that still existed on a separate ship on the motherboard and integrated

00:03:25.760 --> 00:03:32.959
it right into the CPU yes even all those

00:03:29.519 --> 00:03:35.920
pci express lanes that is the secret

00:03:32.959 --> 00:03:40.239
sauce that makes epic so modular and scalable and flexible it means that

00:03:39.120 --> 00:03:46.480
whether we're talking about a motherboard like this one that super micro very kindly sent over to us along

00:03:44.799 --> 00:03:50.879
with the CPU for us to do this preliminary testing or whether you're

00:03:48.239 --> 00:03:55.680
talking about a fully integrated server that takes all those pci express lanes

00:03:53.280 --> 00:04:00.080
and wires them up directly to NVMe drives all across the front of the thing

00:03:57.599 --> 00:04:07.040
instead of using you know splitters and switches and all that kind of nonsense

00:04:03.280 --> 00:04:10.239
AMD doesn't have to go head-to-head with

00:04:07.040 --> 00:04:12.319
Intel in terms of raw CPU performance

00:04:10.239 --> 00:04:16.959
that's not to say that they can't actually the CPU performance we're

00:04:13.840 --> 00:04:19.040
expecting will be very good but it means

00:04:16.959 --> 00:04:22.960
that the solution is just capable of stuff that Intel flat

00:04:22.079 --> 00:04:30.720
out cannot do right now so why don't we fire it up

00:04:26.639 --> 00:04:32.800
it's like mind-blowing that we have 64

00:04:30.720 --> 00:04:38.400
processing cores and a northbridge effectively

00:04:34.320 --> 00:04:40.400
sitting under a single Noctua cooler

00:04:38.400 --> 00:04:44.960
getting all hot and bothered let me take off my sweater nice sweater

00:04:42.720 --> 00:04:47.840
right lct store.com also this shirt

00:04:46.240 --> 00:04:53.520
so for lulls more than anything else we're going to kick things off with cinebench r15 a benchmark that everyone

00:04:52.400 --> 00:04:58.639
knows is sort of light for modern multi-core

00:04:56.160 --> 00:05:01.919
processors never mind modern epic

00:05:00.160 --> 00:05:06.479
look at all those threads it's ridiculous

00:05:03.840 --> 00:05:12.639
it's so dumb and this is cool only two pneuma domains

00:05:10.800 --> 00:05:18.400
and if you're nerdy enough you'll know why that's really cool it is incredibly

00:05:15.199 --> 00:05:21.199
hard to do that with this many cores

00:05:18.400 --> 00:05:27.120
AMD has figured out a way even in their dual or multi-socket configurations to

00:05:24.600 --> 00:05:32.160
dramatically reduce the number of pneuma domains that are required for these

00:05:29.520 --> 00:05:36.720
massive core counts something that Intel actually lorded over them just last

00:05:34.639 --> 00:05:42.080
generation so no more anticipation let's do it

00:05:39.360 --> 00:05:42.080
and it's gone

00:05:44.039 --> 00:05:51.120
8450 in cinebench r15

00:05:47.919 --> 00:05:54.000
on a single CPU it's not even running

00:05:51.120 --> 00:05:58.880
long enough to load up the the to get hot the fan didn't even spin up

00:05:57.440 --> 00:06:08.240
so obviously we're gonna need something a little heavier let's step up to cinebench r20 which is based on a much

00:06:02.800 --> 00:06:10.800
more modern version of maxon cinema 4d

00:06:08.240 --> 00:06:16.319
this thing wrecks r20 the way that high-end desktop Intel

00:06:13.039 --> 00:06:18.400
chips wreck r15 like

00:06:16.319 --> 00:06:26.560
boom this just beat a 48 core configuration

00:06:23.360 --> 00:06:28.319
of dual xeon platinum 8168s

00:06:26.560 --> 00:06:34.520
so more perspective here each of those chips is within striking

00:06:31.280 --> 00:06:36.240
distance of the cost of a single

00:06:34.520 --> 00:06:41.199
7742 and that's ignoring that it takes two of

00:06:39.039 --> 00:06:45.120
them to not even have the same performance not to mention all the

00:06:43.120 --> 00:06:49.680
memory channels and pci express lanes and blah blah blah all that other stuff

00:06:47.600 --> 00:06:53.199
it's madness and things get a little bit more crazy here now the eagle-eyed among

00:06:51.600 --> 00:06:58.080
you probably noticed that we're only running four memory sticks in this

00:06:54.880 --> 00:07:00.080
motherboard right now the reason is that

00:06:58.080 --> 00:07:04.479
at least in our early testing we were having trouble getting unbuffered ecc

00:07:02.639 --> 00:07:08.160
memory to run in it we are also going to be significantly

00:07:06.319 --> 00:07:14.319
upgrading the memory capacity of our system here each of these

00:07:10.240 --> 00:07:15.720
is a 32 Gigabyte dim

00:07:14.319 --> 00:07:23.120
so that will be 256 gigs of RAM so there it is 256 gigs

00:07:20.880 --> 00:07:26.240
of RAM and this hardware is too new to have the readout for how many memory

00:07:24.800 --> 00:07:31.680
channels and what speed it's running at and all that noise so i guess we'll have to fire up like

00:07:29.199 --> 00:07:35.199
hw info yeah okay cool let's do that all right so we're running at 26.66

00:07:33.680 --> 00:07:40.479
which happens to be the rated speed of our memory we've got our rtx 2080 ti

00:07:37.759 --> 00:07:45.199
which is totally inappropriate everything here is looking

00:07:43.599 --> 00:07:49.360
pretty right all right let's try cinebench r20 again

00:07:47.199 --> 00:07:53.360
now to be clear i'm not expecting a huge difference in performance going from

00:07:50.880 --> 00:07:56.000
quad to eight channel memory in this particular workload

00:07:55.120 --> 00:08:00.960
uh there are very few if any single user

00:07:59.199 --> 00:08:05.680
use cases where you're really going to get a benefit from that much memory

00:08:03.280 --> 00:08:10.960
bandwidth it's more for like actual legitimate server use and as expected

00:08:08.720 --> 00:08:14.800
our score is pretty darn similar if you got eight channels y'all might as well

00:08:12.960 --> 00:08:19.759
use them on the subject of single user workloads though here's one that can

00:08:17.280 --> 00:08:25.039
really benefit from extra CPU power let's go ahead and do the classic bmw

00:08:23.520 --> 00:08:29.919
blender render and see just how much of our CPU we can

00:08:27.440 --> 00:08:35.360
load up here wow

00:08:31.599 --> 00:08:38.800
even blender which is traditionally a

00:08:35.360 --> 00:08:41.919
very multi-threaded workload cannot take

00:08:38.800 --> 00:08:44.399
advantage of all 128 of our threads

00:08:41.919 --> 00:08:49.839
maxing out at around 80 85 of them or so

00:08:48.080 --> 00:08:54.720
it's only using half of them is blender numa aware that's fine we

00:08:52.320 --> 00:08:58.080
have a solution to unlock this fully armed and operational

00:08:56.640 --> 00:09:03.839
battle station we're just going to run two instances of

00:09:00.640 --> 00:09:06.959
the render at the same time

00:09:03.839 --> 00:09:10.200
there it is so we are turboing to just

00:09:06.959 --> 00:09:16.080
shy of 2.5 gigahertz we are seeing

00:09:10.200 --> 00:09:18.800
100 usage of all 64 of our cores 128

00:09:16.080 --> 00:09:24.320
threads and i am willing to bet that this thing is kicking out some heat i

00:09:21.680 --> 00:09:28.240
needed to dry my hair cool

00:09:25.920 --> 00:09:30.880
the fan's not really ramping up okay these fins are getting pretty

00:09:29.519 --> 00:09:35.680
toasty is this fan going to ramp up at some point i might not be on the right header

00:09:33.920 --> 00:09:38.880
supermicro doesn't label their headers particularly clearly

00:09:39.440 --> 00:09:46.000
we could just try a different one oops

00:09:43.279 --> 00:09:50.000
so impressively it still managed to finish while running two blender

00:09:48.000 --> 00:09:54.160
instances simultaneously in a minute and 14 seconds apiece all

00:09:52.720 --> 00:09:59.920
right so now that we've got our fan figured out properly let's go ahead and have a look at what we can expect in

00:09:57.120 --> 00:10:06.000
terms of CPU temperatures under a very heavy load so my friends that is 128

00:10:03.360 --> 00:10:12.440
instances of prime95 i've never seen anything quite like that

00:10:08.320 --> 00:10:15.120
and let's see what that does to our poor

00:10:12.440 --> 00:10:18.560
7742 i wonder if it detects this as a power virus

00:10:16.480 --> 00:10:21.760
every thread is only running at 93 94

00:10:20.160 --> 00:10:26.720
so this isn't working and we think the CPU might be detecting prime95 as a

00:10:24.079 --> 00:10:31.440
so-called power virus because it's even throttling below its base speed so we're

00:10:28.800 --> 00:10:35.839
going to go ahead and kill that all right so this is more like it now we're

00:10:33.120 --> 00:10:40.959
hitting every core for all it's worth we're actually managing to turbo a

00:10:38.079 --> 00:10:46.160
little above our base clock to 2.5 gigahertz and

00:10:43.200 --> 00:10:49.680
shockingly temperatures are not even just

00:10:47.200 --> 00:10:55.519
reasonable they're downright under control we're actually only at about 50

00:10:52.320 --> 00:10:58.399
degrees on the CPU now that our fan

00:10:55.519 --> 00:11:03.040
turns up when there's heat going into the heatsink

00:11:01.040 --> 00:11:06.640
now that might seem unintuitive having 64 cores running at a mere

00:11:05.760 --> 00:11:12.880
up to 52 degrees when you've got like an eight

00:11:09.680 --> 00:11:15.920
core Intel processor like a 9900k

00:11:12.880 --> 00:11:17.839
that'll easily run at you know 70 plus

00:11:15.920 --> 00:11:22.480
and it's only eight cores but in this case

00:11:19.519 --> 00:11:27.760
epic's size and the lower frequency of its cores means that not only are the

00:11:25.200 --> 00:11:32.320
cores more spread out making it easier to transfer heat into the heatsink but

00:11:31.279 --> 00:11:36.000
because they're running at a lower frequency and a lower voltage it means

00:11:34.320 --> 00:11:40.720
they're running much more efficiently pushing for that last little bit of

00:11:37.839 --> 00:11:44.640
frequency requires a lot more power to be pumped through the chip and therefore

00:11:42.480 --> 00:11:48.399
a lot more waste heat that dual gooseberry render though but enough of

00:11:46.560 --> 00:11:53.120
all that it's time to answer the question you've all been waiting for can

00:11:50.160 --> 00:11:58.720
it run crisis okay then 720p it is but we're gonna crank

00:11:56.160 --> 00:12:04.160
everything to very high very high is grayed out also motion blur sucks

00:12:01.600 --> 00:12:08.880
anytime now if this takes any longer i'm gonna have a mid-life crisis

00:12:08.880 --> 00:12:12.560
that is pretty slow

00:12:14.639 --> 00:12:22.639
wait a minute Anthony is this the CPU renderer version

00:12:20.720 --> 00:12:27.360
yeah that's why i told you not to run over 720p

00:12:24.880 --> 00:12:31.680
oh wow i'm surprised this is like running at all then

00:12:29.680 --> 00:12:37.200
yeah i had everything on the blow and it's actually semi-playable on low

00:12:34.720 --> 00:12:41.120
okay why don't we try that then i friggin figures i knew you were you had

00:12:39.920 --> 00:12:45.680
some crazy trick up your sleeve alright so i

00:12:43.440 --> 00:12:53.279
turned the in-game settings down to low and this is pretty darn impressive but

00:12:50.240 --> 00:12:56.079
the best is yet to come so in order to

00:12:53.279 --> 00:13:00.480
get this it's using a renderer called swift shader in order to get it to even

00:12:58.880 --> 00:13:05.120
launch the game you have to change your CPU affinity to something other than all

00:13:02.800 --> 00:13:08.720
processors so it looks like eight eight processors total so we

00:13:07.040 --> 00:13:14.000
instead are going to allow it an entire pneuma

00:13:12.320 --> 00:13:19.279
node now let's see how it runs

00:13:16.079 --> 00:13:20.800
this is crazy now to be clear

00:13:19.279 --> 00:13:23.839
no one at google where they're developing the software expects anyone

00:13:22.800 --> 00:13:28.720
to game on cpus

00:13:26.079 --> 00:13:34.160
as the graphics card anytime soon it's designed more

00:13:30.000 --> 00:13:36.240
as like a compatibility layer but uh

00:13:34.160 --> 00:13:41.600
it's working come on i want one kill

00:13:39.279 --> 00:13:45.839
yes all right so now that we're not being

00:13:43.360 --> 00:13:50.240
silly here it is 4k everything cranked to high

00:13:46.959 --> 00:13:52.720
it's actually kind of amazing how still

00:13:50.240 --> 00:13:57.760
kind of respectable this game looks all these years later

00:13:54.720 --> 00:14:00.000
i mean the ai is dumb as toast by modern

00:13:57.760 --> 00:14:04.639
standards and stuff but honestly crisis didn't run well but that's in large part

00:14:02.320 --> 00:14:08.240
due to it just being really really old and not particularly well optimized

00:14:06.399 --> 00:14:12.959
let's run something a little more modern and see how that goes shall we i mean

00:14:10.560 --> 00:14:17.279
apex isn't exactly the most demanding game on the market but it's certainly

00:14:15.040 --> 00:14:22.399
popular so so let's go have a look at how things are running here we are using

00:14:18.959 --> 00:14:23.600
a grand total of two percent of our CPU

00:14:22.399 --> 00:14:26.160
right now um

00:14:26.720 --> 00:14:33.600
overall utilization and we peaked out about 12

00:14:31.279 --> 00:14:38.639
in game we'll be turboing up to around three point okay nothing amazing like

00:14:36.000 --> 00:14:43.360
3.3 3.4 gigahertz but that's more than enough to run this game

00:14:40.560 --> 00:14:46.880
at 144 frames per second average we're actually locked to our refresh rate

00:14:44.800 --> 00:14:51.920
because i didn't bother to adjust it holy crap i think my team is bothering

00:14:49.920 --> 00:14:57.040
to respawn me here wow that uh that was a waste of effort

00:14:55.120 --> 00:15:01.360
appreciate you guys though okay so i don't have any of my stuff now

00:14:59.600 --> 00:15:05.760
though like i'm just naked at this point right wow they're like pinging stuff for

00:15:03.279 --> 00:15:08.560
me i wonder if they know who i am uh h to thank them

00:15:07.199 --> 00:15:14.320
thanks all right all right i'm coming i'm ready to contribute to the team now they're

00:15:12.240 --> 00:15:18.720
they're trying so hard to help me like i feel so bad for them right now

00:15:16.720 --> 00:15:22.800
seven squads left so we're actually like doing respectably

00:15:20.639 --> 00:15:26.800
i think i'm not as much of a liability as dennis

00:15:24.959 --> 00:15:30.240
oh no they pinged a thing we're oh we're going somewhere no no i don't want to go

00:15:28.320 --> 00:15:36.079
anywhere i liked this place this place seemed pretty good oh oh shoot there's

00:15:33.120 --> 00:15:39.360
like enemies all over the town run

00:15:37.920 --> 00:15:43.600
i got a kill they totally like set it up for me but

00:15:40.959 --> 00:15:46.880
whatever i want to win brandon i am a competitive gamer

00:15:45.199 --> 00:15:52.079
hey there's nothing wrong with being supportive okay bras are supportive and

00:15:49.199 --> 00:15:52.079
they're very popular

00:15:52.800 --> 00:15:57.199
actually that's true millennials are apparently killing bras

00:15:57.920 --> 00:16:03.279
okay there's only three squads left ladies and gentlemen

00:16:04.720 --> 00:16:11.199

00:16:18.639 --> 00:16:26.399
