00:00:00.160 --> 00:00:07.520
this NVIDIA GPU has no display outputs

00:00:03.919 --> 00:00:11.040
can't play any games does not exist on

00:00:07.520 --> 00:00:14.320
NVIDIA's website costs upwards of 5

00:00:11.040 --> 00:00:17.840
000 us dollars and it doesn't even have

00:00:14.320 --> 00:00:19.680
a cooling fan and yet it's sold out

00:00:17.840 --> 00:00:24.720
nearly everywhere what the heck is going on with this

00:00:21.840 --> 00:00:27.760
thing it's like a big block of aluminum thanks to ifixit for sponsoring this

00:00:26.400 --> 00:00:31.760

00:00:47.840 --> 00:00:53.199
now the kenaid and brained among you

00:00:50.879 --> 00:00:57.280
might have already figured out what this card is designed for

00:00:54.960 --> 00:01:02.960
crypto mining and yes yes i know but hear me out this video

00:01:00.800 --> 00:01:08.400
isn't about promoting or selling you on crypto mining we're really just

00:01:05.280 --> 00:01:12.560
incredibly curious about these NVIDIA

00:01:08.400 --> 00:01:14.720
cmp mining gpus and because of the cost

00:01:12.560 --> 00:01:17.360
of these cards very few of them have made their way into the hands of tech

00:01:16.400 --> 00:01:21.439
media at least until now

00:01:19.439 --> 00:01:26.640
full disclosure then this was provided to us by vypira who sells these cards

00:01:24.000 --> 00:01:31.200
but we made no commitment to them or to NVIDIA to say anything in particular

00:01:28.479 --> 00:01:35.360
about it not that NVIDIA is likely to talk to us

00:01:32.479 --> 00:01:41.280
that is the first weird thing about this while cmp launched back in february with

00:01:38.159 --> 00:01:42.960
cards like the cmp98 which used a cut

00:01:41.280 --> 00:01:49.439
down version of the chip you'd find in a high-end 30 series gaming card this

00:01:45.600 --> 00:01:51.680
particular model the cmp170hx

00:01:49.439 --> 00:01:56.719
isn't mentioned anywhere on NVIDIA's website social media or even their

00:01:54.240 --> 00:02:01.200
investor calls as far as we can tell it's a complete ghost product

00:01:59.360 --> 00:02:05.280
making matters even more interesting there have been leaks about it on

00:02:02.640 --> 00:02:08.959
twitter since early this year but no hardware made it out into the wild until

00:02:07.119 --> 00:02:13.520
the last couple of months so

00:02:10.319 --> 00:02:15.760
what is it exactly well in line with

00:02:13.520 --> 00:02:20.080
their previous mining cards there are no display outputs this allows NVIDIA to

00:02:18.160 --> 00:02:24.400
cut costs including the royalty that they would normally pay to the HDMI

00:02:21.680 --> 00:02:29.280
forum and it prevents people from using the card as a gaming card potentially

00:02:26.879 --> 00:02:33.760
cannibalizing their GeForce business but there are a few other differences for

00:02:31.280 --> 00:02:38.239
one according to the third party specs that are provided by vipera this card

00:02:36.000 --> 00:02:43.200
does not use silicon that could otherwise have been turned into a gaming

00:02:40.160 --> 00:02:45.120
card in fact it seems to use harvested

00:02:43.200 --> 00:02:50.720
dies that didn't meet NVIDIA's standard for their a100 data center gpus

00:02:48.239 --> 00:02:55.599
that could make things interesting later when we try to game on it anyway the

00:02:53.280 --> 00:02:59.599
second weird thing is that this is an NVIDIA branded and NVIDIA distributed

00:02:58.640 --> 00:03:04.879
card most of the previous mining gpus be they

00:03:02.159 --> 00:03:10.720
cmp or otherwise were manufactured and sold by NVIDIA's board partners MSI

00:03:07.680 --> 00:03:12.480
Gigabyte etc but these cards are made

00:03:10.720 --> 00:03:17.040
at least through a contract with someone like pegatron or foxconn buy NVIDIA

00:03:15.440 --> 00:03:24.000
themselves third it draws its maximum of 250 watts

00:03:21.519 --> 00:03:30.799
not through an 8-pin pci express connector but rather through an 8-pin

00:03:27.440 --> 00:03:33.360
CPU power connector now thankfully

00:03:30.799 --> 00:03:39.840
bipira provided us with an adapter so this is dual 8-pin PCIe to a single

00:03:37.040 --> 00:03:44.159
8-pin CPU connector and that seems to be included by NVIDIA based on these ebay

00:03:42.239 --> 00:03:48.400
listings for the same card that also appear to come with the same adapter

00:03:46.400 --> 00:03:53.760
and then finally let's talk about this cooler shall we

00:03:51.519 --> 00:03:57.920
most consumer graphics cards and a lot of the previous mining cards use

00:03:55.439 --> 00:04:02.159
inexpensive horizontally oriented fans designed for use in an atx style

00:03:59.840 --> 00:04:07.200
computer case or an open-air mining chassis this works great for the home

00:04:04.799 --> 00:04:12.799
gamer or casual crypto miner but that style requires extra space for

00:04:10.080 --> 00:04:17.359
the cooler to operate properly so it's not really ideal for large-scale crypto

00:04:14.879 --> 00:04:21.199
mining so borrowing from the data center playbook the

00:04:18.440 --> 00:04:26.320
cmp-170hx removes the fans from the card all together and orients the fins for

00:04:24.080 --> 00:04:29.520
lengthwise airflow you throw a couple blowing metrons on the end and you no

00:04:28.080 --> 00:04:33.360
longer need to space them out you can just pack them right in which can vastly

00:04:31.919 --> 00:04:39.360
increase density that's awesome for crypto people but for

00:04:36.080 --> 00:04:41.040
me or rather for Jake it meant spending

00:04:39.360 --> 00:04:45.280
some time figuring out how to cool the stupid thing and since we don't have a

00:04:43.440 --> 00:04:49.680
compatible server chassis lying around that we aren't already using in our

00:04:47.520 --> 00:04:55.280
server room um we opted to design a little 3d printed

00:04:52.560 --> 00:05:00.639
shroud that can take a 120 millimeter fan and then direct all of the airflow

00:04:58.639 --> 00:05:06.400
down this slot which we're going to use these included thumb screws to bolt onto

00:05:03.039 --> 00:05:08.800
the back of it and uh yeah we're gonna

00:05:06.400 --> 00:05:12.479
just zip tie the fan to the thing if for whatever reason you end up buying

00:05:10.800 --> 00:05:15.600
one of these cards uh we're gonna have the link to this little shroud thing in

00:05:14.000 --> 00:05:20.000
the video description you're gonna need one heck of a fan on it by the way this

00:05:17.440 --> 00:05:24.320
is uh an industrial ppc from Noctua that runs at 3000 RPM and does some pretty

00:05:22.320 --> 00:05:27.840
good static pressure as well of course there's not much need for me to put the

00:05:25.520 --> 00:05:33.360
shroud on now because before we fire it up we are going to in true LTT fashion

00:05:31.360 --> 00:05:36.800
take this puppy apart you strip it already a little

00:05:35.280 --> 00:05:40.639
really okay so what is

00:05:38.400 --> 00:05:44.240
what cool boy

00:05:42.560 --> 00:05:50.400
oh boy whoa it's what

00:05:45.919 --> 00:05:53.280
it's fake black what what the heck

00:05:50.400 --> 00:05:55.759
is it now hold on just a gosh darn minute here

00:05:54.720 --> 00:05:59.919
okay so what they put aluminum

00:05:58.720 --> 00:06:04.240
heatsink here and here for looks they put these

00:06:04.319 --> 00:06:11.840
is that even metal this one's not connected to anything this appears to

00:06:08.960 --> 00:06:17.280
actually be for looks holy crap this thing is freaking jank Jake

00:06:14.880 --> 00:06:24.000
look at this oh they just like low-key

00:06:20.720 --> 00:06:27.759
solder the pci express connector to the

00:06:24.000 --> 00:06:30.000
freaking contact pads on the board here

00:06:27.759 --> 00:06:34.479
what yeah that's weird is it like that on the cards with the

00:06:31.680 --> 00:06:38.560
no i guess not right so they could have made a like a 30 90 reference that had

00:06:36.960 --> 00:06:43.120
the power connector at the end oh i'm sure they could have clearly

00:06:40.560 --> 00:06:45.600
wow i mean this is not a 30 90 board by any stretch though you can see it's

00:06:44.319 --> 00:06:51.360
actually got one two three sets of envy link fingers

00:06:49.680 --> 00:06:56.479
uh hold on does this does this come out of here what the f

00:06:54.160 --> 00:07:00.000
hey language there are minors there are minors watching this video yeah get it

00:06:59.280 --> 00:07:03.000
yeah yeah

00:07:03.680 --> 00:07:11.120
is it gonna come out oh yeah oh yeah there it goes come on little mining boy

00:07:08.160 --> 00:07:16.720
oh god whoa that is a freaking expensive just like

00:07:14.240 --> 00:07:20.960
cosmetic piece of freaking aluminum men maybe i'm missing something but it looks

00:07:18.639 --> 00:07:28.560
to me like NVIDIA started with a freaking hunk of aluminum this thick and

00:07:24.160 --> 00:07:30.400
just milled away 90 of it for no reason

00:07:28.560 --> 00:07:34.639
other than to just have a beautiful cosmetic backplate on a GPU that nobody

00:07:33.120 --> 00:07:38.560
will ever see because it's in a data center to be fair i think this is the

00:07:36.880 --> 00:07:44.400
same piece that would have ended up on an a100 i know different etched so like

00:07:41.199 --> 00:07:46.319
that's an 11 000 card but still why

00:07:44.400 --> 00:07:49.680
yeah yeah it's just for looks you can see they've reused at least certain

00:07:48.000 --> 00:07:54.000
aspects of the consumer board design because they've got that uh kind of the

00:07:52.160 --> 00:07:58.800
weird fan cut out for the notch pass-through

00:07:55.520 --> 00:08:00.960
uh pass-through cooling i think the a100

00:07:58.800 --> 00:08:03.840
is also like that too but we don't know because we don't have one nobody's

00:08:02.400 --> 00:08:06.879
taking one apart i mean should we take the copper cooler off oh hell yeah yeah

00:08:05.599 --> 00:08:13.280
we kind of have to don't it's our responsibility heck yeah oh don't get

00:08:08.960 --> 00:08:13.280
fingerprints on the copper the edges

00:08:15.840 --> 00:08:22.800
you people drive me crazy just touched all over it oh gosh oh wow oh gentle oh

00:08:21.120 --> 00:08:26.319
god oh okay yeah

00:08:24.560 --> 00:08:29.840
it's thermal epoxy the whole thing the whole GPU

00:08:27.680 --> 00:08:33.440
and the GPU is like freaking this bit it's huge oh no there's got to be a way

00:08:32.000 --> 00:08:37.440
it's not worth it i'm sorry Jake we can't

00:08:35.599 --> 00:08:42.399
oh i say we just send it in strike give it a little bit of force hold on Jake

00:08:40.320 --> 00:08:45.440
actually no

00:08:43.680 --> 00:08:48.240
it might come up i do that see like there's components on there and just be

00:08:46.880 --> 00:08:52.000
patient stick the plastic thing right in there and then twist

00:08:50.320 --> 00:08:56.560
you know i don't want to twist against the component on the board well it's a big component it'll be fine look at how

00:08:54.560 --> 00:09:00.560
much solder's on that bad boy oh my god we're not doing it that way alex will

00:08:58.720 --> 00:09:06.080
heat gun help to get off a thermal compounded thing

00:09:03.200 --> 00:09:09.920
probably but you should just grip it i like his style it's five grand well

00:09:08.240 --> 00:09:12.560
it's his five grand not yours can we twist a little bit wait does it twist

00:09:11.680 --> 00:09:17.680
it i can try a twist i want a glove oh my goodness i'm not

00:09:16.000 --> 00:09:21.600
putting more fingerprints on it look there's a there's a cloth right there use the cloth could you jam it in twist

00:09:20.880 --> 00:09:27.519
it um no i tried he wouldn't let me okay oh

00:09:24.399 --> 00:09:28.399
wow that was easy jesus christ holy

00:09:27.519 --> 00:09:33.440
oh that is a waiting it has an ihs on it

00:09:30.880 --> 00:09:37.680
GPU yeah it does what the hell i need some alcohol should you see this

00:09:35.360 --> 00:09:42.480
it hasn't it's freaking enormous it has an ihs

00:09:39.279 --> 00:09:47.360
holy i know

00:09:42.480 --> 00:09:49.440
oh what is it so it's ga 100-45f

00:09:47.360 --> 00:09:53.760
it looks like the lasering was done using two different processes probably

00:09:51.600 --> 00:09:58.320
at two separate times weird that's really weird does an a100 have an ihs i

00:09:56.320 --> 00:10:02.640
would think so because as far as we can tell they've just reused just about

00:10:00.320 --> 00:10:07.519
everything about the a100 for this card so the sxm cards don't

00:10:05.519 --> 00:10:11.440
have an ihs from what i understand oh the ones that are in the server ones the

00:10:09.760 --> 00:10:16.240
ones where you plunk them down like this yeah okay but the PCIe ones may be for

00:10:14.320 --> 00:10:20.399
whatever reason no idea because nobody's ever taken well they

00:10:18.000 --> 00:10:24.160
can put a bigger cooler on the PCIe version so maybe they need the more

00:10:22.399 --> 00:10:27.760
efficient thermal transfer for the other ones because that's why they did away

00:10:26.480 --> 00:10:32.720
with the other ones are way higher wattage well again then

00:10:30.640 --> 00:10:36.640
that would be why yeah they would want their own 400 watts that'd be why they'd

00:10:34.560 --> 00:10:41.279
want to go bare die for sure then i get such a kick out of this freaking

00:10:39.120 --> 00:10:46.800
PCIe connector here this is hand soldered for sure

00:10:44.880 --> 00:10:49.720
why so it's a different kind of memory on

00:10:48.079 --> 00:10:55.760
this card you see you don't see any gddr6x or anything like that right this

00:10:52.320 --> 00:10:57.519
is all power delivery all around the GPU

00:10:55.760 --> 00:11:01.839
and then there's nothing on the back that's because all the memory is going

00:10:59.680 --> 00:11:06.399
to be under this heat spreader right next to the die and there's only eight

00:11:04.000 --> 00:11:13.360
gigs of it this is really interesting the a100 has 480 40 or 80. yeah also a

00:11:10.880 --> 00:11:16.880
little bit more the advantage of hbm2 is that it gets in closer to the die it's

00:11:14.959 --> 00:11:20.800
higher bandwidth hence the name high bandwidth memory hbm

00:11:18.800 --> 00:11:24.720
uh but the disadvantage is of course cost so that's why it hasn't really made

00:11:22.880 --> 00:11:28.800
its way into gaming cards except when from when AMD experimented with it for

00:11:26.959 --> 00:11:33.839
one generation i think maybe two so the GPU code name in this NVIDIA dock all

00:11:31.279 --> 00:11:38.720
they say is ga100 so we don't even know so presumably it's probably like ga

00:11:36.200 --> 00:11:44.640
100-400 or something like that um but yeah this is 105f

00:11:41.839 --> 00:11:47.839
weird very weird i hope this thing still works

00:11:45.839 --> 00:11:51.680
all of the cooling appears to be done by that copper heat sink that's in the

00:11:49.360 --> 00:11:56.560
middle because these black fins are not connected to anything yeah and this back

00:11:54.320 --> 00:11:59.440
plate is not connected to anything like thermally

00:11:58.000 --> 00:12:05.040
you know i see the copper now that i'm looking at it but i never noticed it before no me neither

00:12:03.519 --> 00:12:08.160
crazy i mean i'm going to tighten them anyway but i i just don't think they do

00:12:07.040 --> 00:12:13.120
anything no they do go through the card though like they go through the pcb oh no i

00:12:11.440 --> 00:12:18.079
know they do they just don't hold anything they don't serve a purpose

00:12:15.279 --> 00:12:21.040
other than to enclose the copper fins so that our

00:12:19.200 --> 00:12:23.120
clamps yeah together exactly that's all they do

00:12:22.240 --> 00:12:27.120
okay well hey are we ready to throw this bad

00:12:25.279 --> 00:12:30.800
boy on here oh man ha ha

00:12:28.880 --> 00:12:34.480
script calls for hydration v2 LTT water bottles now with quad

00:12:32.880 --> 00:12:39.200
channel memory LTT Store.com you ready to fire that up

00:12:36.480 --> 00:12:43.680
uh i'm putting more tape i like tape oh yeah so

00:12:40.800 --> 00:12:48.480
Jake's sealing up our ducks here with well not that make sure you uh it's fine

00:12:46.160 --> 00:12:52.000
seal your duck here it goes

00:12:50.560 --> 00:12:56.560
i see what you mean about the blowback though oh hey oh well there's your problem

00:12:55.200 --> 00:13:04.320
i was just going to plug it in while it's on but whatever nope if it was a 50 GPU i'd consider it

00:13:01.760 --> 00:13:08.320
the crazy part is this is like value compared to the product it's based

00:13:06.480 --> 00:13:13.360
on well the one it's based off of depending on the price is around like 11

00:13:10.240 --> 00:13:14.720
000 us 12 000 us

00:13:13.360 --> 00:13:19.519
it also has 5 to 10 times as much hbm2e i don't know

00:13:17.440 --> 00:13:23.920
how much the 80g ones are i don't know yeah probably more yeah

00:13:21.760 --> 00:13:27.279
now this is interesting a card that is not present on NVIDIA's

00:13:26.079 --> 00:13:32.480
website cannot have drivers downloaded from

00:13:29.760 --> 00:13:34.480
NVIDIA's website in fact this entire cmp series

00:13:33.440 --> 00:13:37.680
is not here nope not it's not under c-class

00:13:36.880 --> 00:13:43.839
either um so we end up on

00:13:41.160 --> 00:13:50.079
viperatec's website where we can go to mining gpus here it is NVIDIA

00:13:46.680 --> 00:13:52.880
cmp-170hx Windows drivers and we tried

00:13:50.079 --> 00:13:58.000
you cannot use the regular g-force or studio drivers with this card they just

00:13:55.519 --> 00:14:01.600
don't do anything so from what i recall i think this is the same version that

00:13:59.760 --> 00:14:05.680
you can download from like MSI's website for the the lower end cmp cards

00:14:04.079 --> 00:14:10.800
oh crazy it doesn't even show up as a display

00:14:07.680 --> 00:14:12.160
adapter it's a 3d video controller

00:14:10.800 --> 00:14:17.360
it's kind of trippy to me that it even has a Windows driver because who in their right mind would be running this

00:14:14.959 --> 00:14:21.600
thing in Windows that's true this is crazy

00:14:18.880 --> 00:14:25.360
so this mining specific driver we just downloaded still has like GeForce

00:14:23.600 --> 00:14:28.560
experience and stuff yeah and you can use it with like 30 series cards it's

00:14:27.279 --> 00:14:34.560
not a it wouldn't be an up-to-date game-ready driver but you could game on

00:14:30.720 --> 00:14:38.320
it with a 30 series which we have yeah

00:14:34.560 --> 00:14:41.440
30 90 for comparison this is so weird

00:14:38.320 --> 00:14:43.120
crap obs crashed while the NVIDIA driver

00:14:41.440 --> 00:14:46.079
was installing that makes sense wait why aren't we sleeping in nbank on it ben

00:14:45.120 --> 00:14:51.199
bank okay you're getting you're getting ahead oh well it's it's an option but it

00:14:49.360 --> 00:14:56.079
doesn't tell me which GPU i'm using yeah you gotta select it so bgpu0 probably

00:14:53.680 --> 00:15:01.360
CPU you know it'd probably be one dude GPU zero i bet GPU zero is that

00:14:58.399 --> 00:15:06.160
there's no way it's GPU zero lunch no i bet lunch we're doing GPU zero now

00:15:04.000 --> 00:15:13.480
and it's going to be the rtx 3090 for like i promise you for lunch there it is

00:15:08.399 --> 00:15:13.480
yeah rtx 39 told you i told ya

00:15:23.760 --> 00:15:32.639
can you enter like GPU-10 wait whoa what's it even doing why is this one

00:15:29.279 --> 00:15:34.480
like 3d engine going crazy i wonder if

00:15:32.639 --> 00:15:38.399
it's like a weird pass-through thing where like the mining card

00:15:37.279 --> 00:15:45.279
has the hardware but it's like it's going to pass it also doing encode i wonder i'm

00:15:42.959 --> 00:15:49.600
more thinking it's like the like on a 30 90 you can pick you want

00:15:47.199 --> 00:15:54.240
the GPU core or the end bank cord to do the encoding maybe

00:15:51.440 --> 00:15:58.000
okay let's try setting it to GPU too start recording oh

00:15:56.160 --> 00:16:01.680
you've selected GPU to set this back to zero and try again all right then

00:16:00.240 --> 00:16:07.440
so it doesn't work okay well that's weird because the data

00:16:04.720 --> 00:16:12.639
center cards do have n-fan hardware as far as we know seems like it yeah gpuz

00:16:10.320 --> 00:16:18.000
then yeah here we go gpuz does not know this graphics device

00:16:15.040 --> 00:16:21.120
yet this is an entirely new one guys good job help the community by

00:16:19.759 --> 00:16:25.120
submitting a validation for the fourth tab heck yeah well we'll start with that

00:16:23.680 --> 00:16:29.279
my name sinus labastian

00:16:27.519 --> 00:16:34.880
i've never gotten to submit a new GPU to gpuz i think it's already listed but oh

00:16:32.720 --> 00:16:40.880
let's have a look at this thing then technology unknown die size unknown

00:16:38.480 --> 00:16:45.360
release date unknown transistors unknown

00:16:42.160 --> 00:16:51.360
oh now this is fascinating whoa is that

00:16:45.360 --> 00:16:53.360
1.1 it uses a PCIe 1.1 by 4 interface

00:16:51.360 --> 00:16:57.360
now hold on a second that may not be quite

00:16:55.279 --> 00:17:00.720
right because even though it might be at that link speed now

00:16:58.959 --> 00:17:06.880
if we hit it with a load it might change it says it supports up to 16. but it's

00:17:03.519 --> 00:17:07.839
still pci 1.1 yeah 1.1

00:17:06.880 --> 00:17:12.559
huh that's really interesting now to be

00:17:10.240 --> 00:17:16.160
clear for mining there's not actually much data transfer that takes place over

00:17:14.400 --> 00:17:19.919
the pci express connection you're just sending the GPU work it's churning

00:17:18.319 --> 00:17:24.160
through it and it's sending you back a result that's it so

00:17:21.679 --> 00:17:29.280
there's no reason i guess for NVIDIA to enable the full pci express gen 4x16

00:17:27.360 --> 00:17:33.200
link that this GPU would otherwise be capable of in fact there's reason for

00:17:31.280 --> 00:17:36.640
them to not that makes it harder for people to potentially repurpose this as

00:17:34.960 --> 00:17:40.480
a card that could do other things even if they could get through any driver

00:17:38.720 --> 00:17:45.280
locks that NVIDIA has put in place which nobody ever would when NVIDIA puts a

00:17:42.720 --> 00:17:48.880
driver lock in place it stays there what are they up to like seventy percent

00:17:47.200 --> 00:17:52.480
efficiency on the low hash rate card seventy one percent everyone hilarious

00:17:51.200 --> 00:17:56.080
but yeah it doesn't increase when you're mining oh okay oh you're mining already

00:17:54.799 --> 00:18:03.080
yeah it's certified okay well hold on hold on i want to look at stuff i want to look at this all right all right okay

00:17:59.280 --> 00:18:06.480
we've got hbm2 memory with a

00:18:03.080 --> 00:18:06.480
4096-bit bus

00:18:06.600 --> 00:18:12.960
1493 gigabytes per second of memory bandwidth

00:18:10.799 --> 00:18:17.760
curiously that bus width is less than an a100 i think an a100 is 50 120 or

00:18:16.480 --> 00:18:21.760
something like that and the a100 bandwidth is higher that's

00:18:19.919 --> 00:18:25.840
still a lot of bandwidth yeah compared to a gaming GPU for sure like a 30 90 is

00:18:24.240 --> 00:18:31.919
under a terabyte a second clocked at 1140 boosts to 1410 same

00:18:28.799 --> 00:18:34.320
boost as an a100 no NVIDIA sli higher

00:18:31.919 --> 00:18:39.760
bass clark interestingly you've been talking a lot about directx oh

00:18:37.039 --> 00:18:43.280
uh directx support unknown go to advanced i think there's you can like

00:18:41.760 --> 00:18:47.120
try it general power limit okay directx 9 try

00:18:46.320 --> 00:18:49.520
that device

00:18:50.000 --> 00:18:57.679
could not initialize interesting so if you were hoping to

00:18:54.480 --> 00:19:00.480
grab one of these and make your own

00:18:57.679 --> 00:19:03.200
cloud gaming service you know obviously well it doesn't have an HDMI connection

00:19:02.000 --> 00:19:09.600
you can't plug a monitor into it directly but i mean people have reused NVIDIA's like

00:19:07.280 --> 00:19:12.240
compute cards for purposes like that you will not be doing it on this one it

00:19:10.960 --> 00:19:18.080
supports cuda well okay and oh interesting not vulcan

00:19:16.000 --> 00:19:20.960
okay let's fire up blender okay is it gonna start at some point here i think

00:19:19.840 --> 00:19:24.400
it's frozen oh wow yeah it's really locked up then

00:19:22.960 --> 00:19:27.919
okay you try optics it does have tensor cores

00:19:26.880 --> 00:19:33.200
so i mean it's trying to do something it's doing a whole lot of nothing

00:19:31.360 --> 00:19:37.039
it's trying to do nothing so the clock speed goes up

00:19:34.960 --> 00:19:40.320
but the GPU temperatures actually don't change it's just still not doing

00:19:39.039 --> 00:19:45.760
anything is that the base clock yeah i think so yeah it's just a base

00:19:43.120 --> 00:19:49.280
huh all its base are belong to us i think blender is just telling it to

00:19:47.360 --> 00:19:54.799
switch power states gear it up to do work that it will then never do yeah

00:19:51.760 --> 00:19:55.840
this is a giant disappointment so far

00:19:54.799 --> 00:20:00.480
i mean only because we got our hands on a

00:19:58.080 --> 00:20:06.080
mining GPU and wanted to do something else on it a 5 000 mining GPU

00:20:04.240 --> 00:20:10.080
okay i mean is now the time to find out if it's at least good at that this is

00:20:07.919 --> 00:20:13.679
gonna mine on both cards um just so we can compare them and we haven't done any

00:20:11.440 --> 00:20:18.400
tuning yet it hit boost clock for a second and then it dialed back a little

00:20:15.280 --> 00:20:20.799
bit how's our power 245 watts temps are

00:20:18.400 --> 00:20:24.559
okay so the interesting thing is it's a mining card but you can't tweak the

00:20:22.320 --> 00:20:29.120
memory speed you can't do really anything the only thing you can adjust

00:20:26.559 --> 00:20:32.240
is the power limit which we should do because when i was messing around with

00:20:30.320 --> 00:20:38.240
it earlier by default it draws 250 watts and mines like 164

00:20:36.159 --> 00:20:44.480
mega hash in ethereum but if you turn it down to like 80 it

00:20:40.480 --> 00:20:46.000
does 160 mega hash at 200 watts which is

00:20:44.480 --> 00:20:50.880
way more efficient you're barely losing anything oh wow all right there we go oh

00:20:49.360 --> 00:20:54.480
yeah so there you go it's all locked down i kind of i give you can change the

00:20:52.720 --> 00:20:59.200
core clock but let's not i give the community not that long to

00:20:57.360 --> 00:21:04.000
figure out how to change more stuff on these things it's hard with NVIDIA cards

00:21:01.039 --> 00:21:06.240
wow look at that 200 watts and

00:21:06.559 --> 00:21:12.240
the memory tips in the 30 90 are just ripping

00:21:10.320 --> 00:21:16.400
wow look at that i guess that's one advantage to having

00:21:13.840 --> 00:21:20.640
that ihs is that your hpm is now going to be cooled by your main GPU cooler

00:21:18.799 --> 00:21:25.440
yeah there's no there's no things on the back yeah there's hardly any difference

00:21:22.400 --> 00:21:28.720
in temp between the hbm2e and the GPU

00:21:25.440 --> 00:21:33.200
so the 30 90 is 275 kilohash a watt and

00:21:28.720 --> 00:21:35.600
sorry what is the cmp 840 800

00:21:33.200 --> 00:21:38.960
and i've seen people with a Linux os that's a little bit more efficient can

00:21:36.960 --> 00:21:44.960
get like around 850. so like yeah that's insane mind you a

00:21:43.039 --> 00:21:50.080
tuned 30 90 you could probably get around 400 kilohash a lot

00:21:47.520 --> 00:21:54.400
it's still double double and that's with us tuning it in like

00:21:52.559 --> 00:22:00.640
four seconds 372. we could definitely get to 400

00:21:56.240 --> 00:22:02.640
kilohaw i'm sure how can this be

00:22:00.640 --> 00:22:08.000
40 to 50 faster than the top-tier GeForce GPU and

00:22:06.320 --> 00:22:12.880
double the efficiency while on the same ampere architecture

00:22:10.240 --> 00:22:16.559
yeah it's crazy okay let's talk about that there are a number

00:22:14.480 --> 00:22:21.200
of reasons but the main one is likely memory bandwidth the ethereum mining

00:22:18.559 --> 00:22:26.480
algorithm et hash is almost entirely bottlenecked by memory bandwidth so if

00:22:23.280 --> 00:22:28.480
you have an approximately 50 memory

00:22:26.480 --> 00:22:33.360
bandwidth difference and that correlates to a 40 to 50 performance difference

00:22:31.679 --> 00:22:37.360
that mostly checks out as for the power draw

00:22:35.120 --> 00:22:42.159
while they are based on the same ampere architecture the a100 silicon is

00:22:39.760 --> 00:22:44.960
manufactured on tsmc's seven nanometer process

00:22:43.120 --> 00:22:48.640
rather than samsung's eight nanometer process which is what's used on the 30

00:22:46.640 --> 00:22:52.640
series gaming cards that's going to help you on efficiency for sure

00:22:50.640 --> 00:22:56.960
so there's no doubt that this is a killer piece of hardware for crypto

00:22:54.799 --> 00:23:00.159
miners but there are still a couple of questions left to answer

00:22:58.640 --> 00:23:04.640
with the looming proof-of-stake migration for ethereum on the horizon

00:23:01.919 --> 00:23:09.840
does it make sense to buy a pricey card that at current profitability could take

00:23:06.640 --> 00:23:11.919
about a year to pay itself off and has

00:23:09.840 --> 00:23:16.240
zero value whatsoever outside of mining crypto

00:23:13.280 --> 00:23:19.280
well if NVIDIA's shortfall in cmp business unit revenues are anything to

00:23:18.320 --> 00:23:26.000
go by most people think probably not reselling old mining cards

00:23:24.000 --> 00:23:30.640
is one of the ways that miners will recoup their costs in the event of a

00:23:27.600 --> 00:23:32.080
crash or a legislative change i'll let

00:23:30.640 --> 00:23:38.559
you guys make the final call on all of that though i guess it's also time to make the final call on NVIDIA's claim

00:23:35.200 --> 00:23:41.520
then that cmp products would not affect

00:23:38.559 --> 00:23:45.679
the shortages of gaming products because they would not be redirecting silicon

00:23:43.360 --> 00:23:51.200
that could have ended up in a gaming GPU and in this instance it actually does

00:23:48.320 --> 00:23:57.600
appear that there's validity to NVIDIA's claims this GPU is clearly compute only

00:23:54.799 --> 00:24:02.159
with no meaningful gaming utility though the same cannot necessarily be said of

00:23:59.679 --> 00:24:05.919
the other cmp cards let us know if you'd like to see us take a look at those in

00:24:04.320 --> 00:24:10.960
the future whether you've been thinking about learning to repair your own devices or just wanting to take your

00:24:48.799 --> 00:24:56.720
check out the video we did a few years back on how asics worked for mining that

00:24:52.960 --> 00:24:56.720
was a very interesting one
