Well reason you get crap performance is a VM can only see 4 of the GPU clusters per VM. To expose more to a VM you must buy NVidia VGPU licenses. Run into it often with GRID and ESRI.

@@noahbuzelli4245 why?, the piece of aluminium you're milling itself is cast
from an engineering standpoint. the black fins on the ends are probably "Flow straighteners" they reduce the mixing of air in the channel to decrease differential pressure through the cooling section. allowing for a larger heat transfer from the fins to the cooling medium.
Ah this makes a lot of sense. Essentially creating a uniform flow distribution for the heated air?
Aka creates something closer to laminar flow

The biggest flex is getting a gpu case made entirely out of aluminium even though no one can tell
Glad we aren't wasting aluminum (aluminum alloy) on this.
Fun fact we are facing a magnesium shortage which will affect aluminum alloy production... Which gets used in Many products including cars. So yes...
Just take it off and sell the aluminium, then stick the cards in the same chasis... open to the air with forced induction will cool them better and you will get a fair bit for the metal you scrap.
@@robertt9342 magnesium shortage? lol just strip mine using a fortune III and eff V diamond pick, mining isnt that hard
It's a big heat sink - maybe not very effective due to placement
Linus is right too. Looks like it was a solid thick piece of aluminum and they just milled 90% of it away. Oof.
The outer fins kinda seem like they guide the air a bit more since running copper fins that far would be expensive. Also they cool the card body and having all those cards nearby in slots would probably be pretty good at keeping them all cooler to the touch.
The question that remains: How much has Nvidia already earned by mining for itself?
I know this is an old comment but I always wondered this. Even if they just did a 5 hour validation test on each card they manufacture just to make sure it will preform to it specs... that is a lot of hashpower... lol
its probably more profitable to design and sell the tools to the rubes than waste time and pr to mine themselves.

Just to let you know, when you're doing your very first render on the Eeves (or Cycles i don't remember) engine, the engine has to compile itself before actually doing rendering. After waiting like 10-15 minutes you will be able to do rendering after rendering.
You can see at 19:22 on the line where you can see your frame count, the message "Loading render kernel (may take a few minutes for the first time" indicating you that you will have to wait a bit.
Hope you will test this out later or read this comment 😀
Could be, but Blender not responding is a hint it probably crashed and would never render. In my experience the BMW test also does not take more than 1-2mins of compilation. Edit: Maybe im wrong, my experience is without OptiX and only with OpenCL / older CUDA
@@somestarwarsnerd9068 ..Blender not responding is as much a hint as it simply not responding for several other reasons outside the specific GPU... How many of us* have had to revert to an auto-save after a lock up or crash & it wasn't due to hardware issues to start with? Lol.. No matter how 'simple' or complex a given scene is, there's always the unexpected.
Furthermore, if due to instability- you do the same thing again and again and prove it IS the card; or something related to it (to help give your comment a sense of merit). But that wasn't the case now, was it?.. /shrug
Edit: "*" typo
They did! Check the pinned comment for benchmarks
The OptiX render kernel isnt precompiled in blender and always takes time in new scenes. CUDA on the other hand comes precompiled with blender so there isnt any kernel compilation happening anymore.
This is why alot of times CUDA will be faster on big single frame scenes that uses nearly all Cycles features, its already done when OptiX is still compiling. When it comes to rendering out big animations OptiX will get the throne.
But yeah this is why in my opinion these OptiX vs CUDA tests in blender are crap because they dont show the complete picture
@@somestarwarsnerd9068 No not at all. Blender is mostly single threaded and is poorly coded in python. Everything runs on one thread including the user interface. Most programs use at least 2. One should be reserved solely for the user interface. That way when you run tasks on the other thread it doesn’t freeze the interface. Even when blender uses more than one thread it still likes to run stuff on the user interface thread. So when doing any operation it freezes. This is because when operating on a single thread code most run in order. So The user interface cannot update until the other code runs. Windows considers programs with unresponsive interfaces to be unresponsive even if it’s just because they are running long code in the UI thread. When modeling in blender applying modifiers or moving objects or editing them in anyway way really can cause blender to become unresponsive but it almost always finishes whatever code it is running and comes back. The exception to this would be if it runs into an error and gets stuck in an infinite loop. Then it stays frozen forever and there is no way to cancel it. This is a common issue with modifiers because they use algorithms which do not always work on the object but blender isn’t smart enough to figure that out so it just keeps retrying. It has a lot of work left to do and certainly is not an ideal program to be using for these kinds of test. Blender is by far the best 3D modeling software and for the best software for physics, animation, and many other things too. It is free to yet still significantly better than stuff that coats you to pay several thousand dollars a year. It shameful for it to cost that much in the first place but subscription based model on top of that really is bullshit. People should own the stuff they buy especially when it’s that expensive. It doesn’t even cost them anything it’s 100 percent profit. They spend a small amount developing the software after the first few customers all the expenses are paid for but the price never drops. And the super cheap support that you may need to use once every few years for a few seconds doesn’t justify it either. The initial cost can easily cover that. Blender while open source still has a foundation with paid employees which has much more expensive and educated employees and much more of them. The research and programming that they put into it goes above and beyond anything any of the companies do yet they do it with a very small fraction of the money that they only get from donations. Things like autodesk and maya may have 50 developers at the most. Autodesk doesn’t even make most of its own software. They buy successful software. Then they make it free to bankrupt any competition out of business. Once the competition is gone they take away the free version and sell it at an extreme cost or at least limit the free version to the point where it is unusable. Almost none of their software is original and not purchased from another company. These companies also have a very small market share. If you take the publicly available revenue for these companies and only look at the small portion of it that they get from their software than divide that by the insane cost you find out that the number of copies they are selling is actually incredibly small. They just want you to think everyone is using it. The only way they stay a float is by making partnerships with universities and collages to teach people to use their software for free so that once they go out into the work force that is what they use. They also makes exclusivity deals with big companies and get them using their software. And once a company is already using a software and the people coming out of school are too it means it would take a huge up front investment of time and money to switch to blender or another alternative even if they would more than make the money back in the long term they don’t want to make the risk and may not have the cash flow to do so. These companies and their software really are unethical predatory crap that isn’t even as good as free alternatives that they didn’t even make or contribute much to. They just steal the ideas of others. Blender however is only better when it comes to capabilities and features. When it comes to performance with large scenes it is still behind. Plus because it has so many features they are often buried in menus and with complicated keyboard shortcuts and they like to change where everything is each update making it a real pain. You can do a lot more with blender but expect it to be super slow and unresponsive while doing it. It doesn’t even matter if you have a super computer because it can easily saturate that too. The only real fix is to recode blender from the ground up because it’s issues are so deeply rooted. They have almost completely redone it a few times and have made big improvements but it’s got a ways to go. They plan on fixing a lot though in the next major update then maybe it will finally make its way into the big companies and snuff out the other crap.
Linus, "This Card can't game"

But they never did. - The end.
I used to work at an hp assembly factory putting together servers, testing them and boxing them up to ship off to whatever country. There was one line boxing up these cards, or an earlier version of them about 6 years ago. Same style minimal casing, no output ports and I could never find them talked about on an Nvidia site but could find other people selling them for 4k+

LMAO NICE ZERO WING REFERENCE
Its possible the black fins are to ensure that the air passes in a straight line through the card rather than whirling around. They probably found extending the copper didnt help with temps as thermal transfer isnt affective that far from the die (or ihs) in this case
it was probably cheaper to use the aluminum back plate from another card rather than create and order a new design of backplate for that card, they probably had to order them in bulk from another company for the other card so they used the access plates or defective units for this card since visuals don't matter. might be a strange area where being cost effective looks nice, feels great.
It's simply a matter of binning. Whoever said binning is not a thing anymore is an idiot. These card's silicone wouldn't be suitable for a gaming environment, but for more focused one, like crypto mining, they are more than enough. It's a great way to use everything and also finally stop the gaming cards shortage.

Not sure where to ask this? Would LOVE LOVE to see a complete how to vid 😉 for properly setting gaming settings? Especially for mid to low range computer set ups??? This would be soooo helpful as issues frequently comes up.
The real reason for the slow PCI is that this would go into a big, cheap chassis with a huge PCI fanout - think 8 cards in parallel using PCI 1.1 risers so that it can fit into a 4u server case. The rest of the design seems to be optimized for energy and cost efficiency.

Shit, before it was released you’d probably see it listed for $10,000
You ever try to take out a mortgage on a graphics card?
Well the aluminium block is quite expensive. :D
I believe the milled back plate would indicate their expected volume for this product. If they were to cast it and then mill it that would be expensive molding costs. On low volume milling is sometimes more cost effective even if you’re milling 90% away. Just hog it out with a big tool to rough in and then finish it.
But it doesn't need a milled backplate.
Just a bend sheetmetal or plastic part would function the same.
@@Jehty_ plastic injection molding requires tooling, sheet metal stamps also would require tooling.
yeah i thought the same thing when i saw the hand soldered supplemental power connector. obviously arent being sold in high volume
My guess is that it is an extruded profile that they mill down for clearance. It's kind of hard to tell from the pictures though.
@@Finder245 my thoughts as well
Coming back to this man's channel and the intro music still the same. Epic love.
Looks like our teacher made that gpu because we can’t game in school
This card was clearly made with low volumes in mind. I mean a bunch of the stuff you guys pointed out and were confused by is likely influenced by the relatively low volume.
6:12 Believe it or not, that's a very common ways to connect a wire to a board at low volumes. Or high volumes with some removable custom fixtures. A lot of LED boards in the small red & yellow lights on semi tractor-trailers are constructed this way so you know it's reliable if done right. In this case, it also allows the connector to be screwed to the enclosure independent of the card, which helps reduce strains on the solder joint due to vibration, etc.
7:12 Milling away 90% of the material is fine - you just dump the scrap in a vat to burn a away the cutting fluid and melt the slurry, clean it up a bit, and cast another block. Great recovery rates.
As for why, it's a low investment way to get a box with 3 sides. The cost per piece is going to be on the order of $10, and you don't need to spend a few hundred thousand dollars on a forming die, to then still spend about $10 per piece on top of that because of your low volumes.
On a related note, 5:46 I wonder if those heat sinks are for cooling the enclosure. Aluminum has got to pick up lots of heat from adjacent cards and this helps carry some of that away.
^ this needs more upvotes
Regarding the soldered connector: soldering those couple of wires is likely much cheaper than using a larger PCB just to bring the connector out further. It is also less likely to fail than a directly soldered connector and it does not bend the PCB. All around, not a bad design.
I know next to nothing about manufacturing or tech and was thinking many of the same things. Why incur "conventional" costs for an unconventional product...
100% for you
The heat sink is clearly designed to have some thermal mass to stabilize long term temperature fluctuations and cooling requirements when running these at scale at 100% uptime.
Worth pointing out that the A100 doesn't have NVENC, only NVDEC. It also lacks most of a graphics pipeline, so not really usable for much except pure CUDA compute
Some GitLab projects then i guess that uses CUDA or Tensor cores for calculations and stuff.. ?
but the mining cards only having 8GB of HBM2 really limits their usability in compute workloads. Pcie 1.1x16 does not help either :P
That power connector extension has been normal on Quadro for years now. Since all Quadro/Tesla boards are standard length and have rear-facing power connectors, they make a cable extension whenever the PCB is shorter than the shroud.
Cool. I was thinking maybe it was for added durability (for some reason) so there would be no chance of breaking the solder connections to the board.

Yes, that looks identical to an A100 PCIE card, and the IHS is on the PCIE version. The A100 does have 3 NVLINK spots as well.
(Ps) on the $12k A100 the power connection is soldered just like the mining card is.

Maybe this mining card has only INT computations and zero floating point computations processors
@@Haskellerz I doubt it. I do some work on deep learning. It would be interesting to test. There’s some simple ways using Tensorflow to test for speed up. It’s down to if the tensor cores are still active.
@@davidedwards7172 wouldn't bother. 8G memory is too big of a limit for it to be useful.
@@jfolz not gonna argue with you there, there are some CUDA tricks around that. If the card sold for a lot less it might be worth it. Especially with the PCIE 1 link, it would be really slow. It would be fun to do a deep dive and see what functions are still left alive on the chip.
Would nvlink work?
What you guys should do is a watt for watt comparison of 30 series vs 40 series cards and include some odd ones like workstation cards. Cards like the rtx a5000 and that a100, if you still have it. Target certain break points, like no aux power, 1 6-pin, 1 8-pin, 2 8-pin, etc.
The plastic fins are to prevent debris and cables blowing in. I also orient them the other way around (the side where the HDMI/DP would normally be towards the intake fans) because... well, that's just how my chassis is designed. CSE-4U8GPU-MRSC
Also, you can't select it for encoding bc it's not recognized as a display adapter in your system.
You don't need a lot of bandwidth (PCIe) as most will be connected to a 1x extension anyway + You just need to load the mem with the DAG and that's it. (like loading textures in a card's mem)

The efficiency benefit is probably related to memory type as well. HBM is more efficient than GDDR. If this card has the same tensor core capabilities as the A100, it will be a pretty good deep learning card, though the 8GB memory is too small for that.
so it won’t
I almost thought that I was going to be able to score a cheep A100 until I heard about the 8GB memory :(
Yeah 8GB. Makes no sense. You cant train anything for that except for very small networks. I mean this is why you can get the clusters of A100. I personally had problems with the AWS EC2-P4d instances on big models. And they have up to 8 A100.

Currently in a mechanical engineering major at a top university in canada, I think the fins linus was confused about was intended to oriente the air into a lamar flow which would increase air flow and air speed through the actual heatsink mounted to the chip, with all the air moving in the same direction (as the other air and the fins) less energy is lost between particle interactions compared to if the air had to oriente in the heatsink. This assumes that the fans output is turbulent which I dont know for sure.
i can see why they might have done what they did with the chassis around the card. the big thing is that its serving as a shroud to channel air both through the heat-sink and then passing it all the way to the end of the card.
the dummy heat-sinks on either end, those server fans can move a lot of air and those are going to act as grills to help protect against things being pushed/pulled into the card by the air flow regardless of which direction the server is using.
i can also see the aluminum box being useful in those server racks with protection against things pushed against the card. i think the high end milled aluminum surface is a bit out there, but if it remains a long term thing they can probably either l simplify it or switch to a casting. but if they use it for other designs or it remains in low rate production, its probably as cheap as any other option.
Well, there is one problem though. The Manufacturing for the CMP Card has to be splitted even if it is not on the same process. This uses TSMC 7nm, like the Ryzen 5000 Series Processors or AMDs Graphics Cards for that same matter. So this new Card may not cut on NVidias own productions, yet. But it may hurt other ones productions.
Probably a happy little accident for Nvidia then.
@@TheRealAtello But is it an accident though? ;)
Actually it sounds like this card runs from the discarded datacenter production line of their products So the main purpose of that line is to produce the card that end up in the true compute datacenters and these cards are the ones that fail QC for that branch and they can't create a tier for. So instead they squeeze out money from the miners that are willing to drop 5k on it.
Its funny how many people think that people that mine in bulk actually use these cards to mine XD
That milled alu chassis and hand soldering are consistent with low volume production methods. Perhaps you were given one of the pre-production test mules or and early production model that's been around the block once or twice, and they've improved the manufacturing efficiency since then?
5:00 Linus had me really worried standing the card up like that.
I am waiting for the result of that meeting linus got set up with CZcams management. I believe it is going to be a 15 minute "$hit management says" episode XD
My money is on CZcams not doing shit, even with Linus on their case. They don't give a fuck. Only about corporations and advertisers.
I have actually heard that closely packed GPUs can cause mining to slow due to electromagnetic interference. I wonder if that was one of the reasons to encase the whole card in metal?
That'd be fun to test! :D Regardless of whether it is true or not, the great questions lead to great discoveries!
@@tradingnichols2255 it would be fairly expensive if you don’t already have the cards but it should be just a matter of getting two of those rigid connecting bus card things filling them with mining cards and putting one upside down over the others or just getting the flexible PCIe cables and sticking the cards as close to tether as you can. And then fiddling with the shielding on the cards and the card positions.
@@glenecollins I would assume so he always encases the shell
I'm thinking they are using the heatsinks at the front and rear of the cooling shroud to help keep laminar airflow through the main cooler.
The black fins are for laminar flow, it makes the air flow less turbulent thus more efficient

Being in the process of scaling up for manufacture, it's development vs. volume costs. If it'll take your team a week to adjust things so that the connector is in the right place, and another 2 for verification and testing, and you're only making a few thousand of the things, it's cheaper to just pay the factory workers to fiddle with wires, rather than the engineers to develop a solution that doesn't need them.
I'm starting to see how that function evaluates now, being the person who both develops and manufactures the parts, which things to spend time developing versus simply producing as they are is one of the harder decisions.
I recently went through the process of getting a electromagnetics simulation server for my job and we got an A100 PCIe 40GB. Really had to hold back and not take it apart. It absolutely slams in CST Studio Suite 2021 though. No complaints about the power and sim time reduction. Really such a bizarre card and such a specialized product that it's completely underwhelming for most people
In the event the need for that card evaporates, or gets replaced, it is your moral duty to the computer community to strip that thing to the traces.
CPU power connectors are common on datacentre PCIE GPUs, and also on some Quadro GPUs (the A6000 uses the CPU pinout, the P5000 uses PCI!)
Using a gaming GPU for mining: "oh easy. Just bypass LHR mining 2 coins, change drivers or some hardware hacking tricky"
Using a mining GPU for gaming: "No bro, you just can't, there is no possible way to do it. We can't let gamers affect mining GPU market"
I know right. I just learned from Seb Fintech and 2 miners how to dual mine and it went really well for him on a 3080 or 3080 TI, I forget. Bascially eliminates the LHR problem for mining. Can't wait to get my hands on one at a reasonable price.
Alex the actual engineer. "Just rip it"
Linus looked a bit upset just at that moment. The pressure of breaking a $5k card might have blocked his understanding of humor right then.😄
Miners stealing GPUs from gamers to mine, Linus stealing mining GPUs from miners to game. Linus has played the Uno Reverse card.
its not stealing lol.
@@finkyfamboni4333 You are correct. Mining is not stealing, it is a war crime
@@1000_Gibibit innit I legit was going to build my pc last year for around 1.8k AUD with a 2070 super OC, now I have to build it for 2.6k this year with a 2060 OC, I hate miners
@@tobias8351 fam you didn’t pay 929 AUD for a 3 year old gpu
I love the brotherly-like banter.
it chould be possible to stream graphics output from a mining card playing games by writing a program that creates a virtual screen to print the game graphics on. the data probably do contain game graphics if the card was running a game. its probably just a array of numbers streamed from the card that you can aranged into a screen size and then copied into the real screen trough direct draw putting a little work on the cpu or using another graphic card with gl to output the graphic. technically a screen is just a big array of numbers divided in colums and rows. it chould not be to much a problem to wrap that into the screen by either the cpu or another graphic card.
12:30 next up: we turned this LTT Waterbottle into a Gaming PC!
That is actually a good idea it would be more possible if it was huge
Imagine Someone buying this for their son not knowing anything about it.
Son: “I guess my time as a gamer is up. Now I must become a minor”
I remember back in the days when my dad bought me a Quadro GPU as a present 😂
Then their son has a chance of becoming a data scientist.
I can't cuz nobody can afford 5k gpu for their sons lol
There is a reason Nvidia doesn't sell it alongside there normal cards, they don't want that to happen
I’ve been running a Tesla M40 (basically a datacenter 980ti) in my rig for a while now and the way to enable directx on a card like that’s is to>cmd as admin>type in “Nvidia-smi.exe -gom=0”> then type “Nvidia-smi.exe -dm 0” to set the gpu to wddm mode for graphics uses>reset pc>open regedit and find the folder that holds the adapter type inside> delete adapter type and create a dword 32bit with the name “EnableMsHybrid”> set the value as 1 on the command and reboot> check for directx on gpu-z if not repeat
These kind of gpu’s do require a cpu with built in graphics like one of AMD’s apu’s
Compare cooling with a 3d printed frame... great videos
_Sigh_
I just want a 700 dollar GPU.
Same
me too
Yep
Same. Even $700 is stretching it by quite a bit.
I still remember when we can get rx580s and gtx 1060s for a reasonable price
Linus, please stop making videos about anything else! This guy in particular doesn't care, his opinion is the most relevant out of all
I love this kind of video, looking at weird tech is always awesome. Would love to see more stuff like this.
I love how the whole squad had to come to open the GPU
5:27 "Before we fire it up, we're going to in true LTT fashion, DROP IT!"
Mining cards are great for mining, and thats it. Its a professional mining card, as as Linus mentions even for most miners it wouldn't be worth it because you cannot repurpose a card so it leads to landfill waste when they are no longer making sufficient profit. I get that they don't want the card to be repurposed but its not a good practice ethically or logically.
The ROI on that card would be insane too.. dont see hows its practical for anyone
Well mining isn't a good practice, ethically or logically either, so that tracks at least...
@@Arclite02 good to know that you don't understand purpose of mining proces.
@@SlawcioD I understand it just fine. Billions upon billions of dollars in wasted equipment, colossal amounts of wasted power and needless emissions, all to make a small group of people who have the millions of dollars to set up a mining farm, obscenely rich at the expense of everyone else.
@@SlawcioD Tell how is mining a good thing?
The aluminum grates might induce Laminar flow. Does that make air convection better or worse?
Generally worse
That pcie to 8 pin cpu adapter was foreshadowing of the 12VHPWR to come D:
this aged like fine wine
Context?
@@theoriginals9821 to my knowledge, etherium doesn’t require mining anymore so that card is relatively worthless. Look up “proof of stake”
“Fine milk” would have made sense too
GMiner needs to update their readme to say "used by LTT."
Another reason for the efficiency bump is HBM also uses much less power than typical graphics memory.

ok i have a dell t7500 workstation with twin 5680s and have a k2200 video card plus a k80 . its so smashed full from the factory i tore everything out of the case and put it all into a cooler master haf 922 . now it has all kinds of room had to cut wires and slice some thing to get all to work but get it to go and is totally worth it ! to cool the k80 is very easy . you need to use 2 40mm base side out put water cooler blocks . i have a evga clc 120 water cooler ut one line and feed it to the first block . then connect the 2 with the out from the frist block to the in of the second block . then take the out from the 2nd block back to the hose you cut to complete the cooling . the evga fans sucked so i got a $20 Noctua NF-F12 PWM and it works awsome . it works so good that my temps never go over 90 degrees . so i put together the same thing for my cpus and now you cant even hear it run and cpus are at 80 degrees . to combat leaks i used brass barb fittings sealed with pipe dope and used house pex water pipe that i heated up to shrink to the fitting then clamped them . after that zero leaks system has been running for 2 years now non stop 24/7 !!!!

I wonder if these could be used for Fold@Home or other non 'make ALL the money' compute projects. Lord knows I've killed my poor GT520 silent doing F@H work, and the 5700XT could probably use some fans (sapphire is nice enough to sell them at least)
