1 00:00:00,160 --> 00:00:07,520 this NVIDIA GPU has no display outputs 2 00:00:03,919 --> 00:00:11,040 can't play any games does not exist on 3 00:00:07,520 --> 00:00:14,320 NVIDIA's website costs upwards of 5 4 00:00:11,040 --> 00:00:17,840 000 us dollars and it doesn't even have 5 00:00:14,320 --> 00:00:19,680 a cooling fan and yet it's sold out 6 00:00:17,840 --> 00:00:24,720 nearly everywhere what the heck is going on with this 7 00:00:21,840 --> 00:00:27,760 thing it's like a big block of aluminum thanks to ifixit for sponsoring this 8 00:00:26,400 --> 00:00:31,760 video

might have already figured out what this card is designed for 14 00:00:54,960 --> 00:01:02,960 crypto mining and yes yes i know but hear me out this video 15 00:01:00,800 --> 00:01:08,400 isn't about promoting or selling you on crypto mining we're really just 16 00:01:05,280 --> 00:01:12,560 incredibly curious about these NVIDIA 17 00:01:08,400 --> 00:01:14,720 cmp mining gpus and because of the cost 18 00:01:12,560 --> 00:01:17,360 of these cards very few of them have made their way into the hands of tech 19 00:01:16,400 --> 00:01:21,439 media at least until now 20 00:01:19,439 --> 00:01:26,640 full disclosure then this was provided to us by vypira who sells these cards 21 00:01:24,000 --> 00:01:31,200 but we made no commitment to them or to NVIDIA to say anything in particular 22 00:01:28,479 --> 00:01:35,360 about it not that NVIDIA is likely to talk to us 23 00:01:32,479 --> 00:01:41,280 that is the first weird thing about this while cmp launched back in february with 24 00:01:38,159 --> 00:01:42,960 cards like the cmp98 which used a cut 25 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 26 00:01:45,600 --> 00:01:51,680 particular model the cmp170hx 27 00:01:49,439 --> 00:01:56,719 isn't mentioned anywhere on NVIDIA's website social media or even their 28 00:01:54,240 --> 00:02:01,200 investor calls as far as we can tell it's a complete ghost product 29 00:01:59,360 --> 00:02:05,280 making matters even more interesting there have been leaks about it on 30 00:02:02,640 --> 00:02:08,959 twitter since early this year but no hardware made it out into the wild until 31 00:02:07,119 --> 00:02:13,520 the last couple of months so 32 00:02:10,319 --> 00:02:15,760 what is it exactly well in line with 33 00:02:13,520 --> 00:02:20,080 their previous mining cards there are no display outputs this allows NVIDIA to 34 00:02:18,160 --> 00:02:24,400 cut costs including the royalty that they would normally pay to the HDMI 35 00:02:21,680 --> 00:02:29,280 forum and it prevents people from using the card as a gaming card potentially 36 00:02:26,879 --> 00:02:33,760 cannibalizing their GeForce business but there are a few other differences for 37 00:02:31,280 --> 00:02:38,239 one according to the third party specs that are provided by vipera this card 38 00:02:36,000 --> 00:02:43,200 does not use silicon that could otherwise have been turned into a gaming 39 00:02:40,160 --> 00:02:45,120 card in fact it seems to use harvested 40 00:02:43,200 --> 00:02:50,720 dies that didn't meet NVIDIA's standard for their a100 data center gpus 41 00:02:48,239 --> 00:02:55,599 that could make things interesting later when we try to game on it anyway the 42 00:02:53,280 --> 00:02:59,599 second weird thing is that this is an NVIDIA branded and NVIDIA distributed 43 00:02:58,640 --> 00:03:04,879 card most of the previous mining gpus be they 44 00:03:02,159 --> 00:03:10,720 cmp or otherwise were manufactured and sold by NVIDIA's board partners MSI 45 00:03:07,680 --> 00:03:12,480 Gigabyte etc but these cards are made 46 00:03:10,720 --> 00:03:17,040 at least through a contract with someone like pegatron or foxconn buy NVIDIA 47 00:03:15,440 --> 00:03:24,000 themselves third it draws its maximum of 250 watts 48 00:03:21,519 --> 00:03:30,799 not through an 8-pin pci express connector but rather through an 8-pin 49 00:03:27,440 --> 00:03:33,360 CPU power connector now thankfully 50 00:03:30,799 --> 00:03:39,840 bipira provided us with an adapter so this is dual 8-pin PCIe to a single 51 00:03:37,040 --> 00:03:44,159 8-pin CPU connector and that seems to be included by NVIDIA based on these ebay 52 00:03:42,239 --> 00:03:48,400 listings for the same card that also appear to come with the same adapter 53 00:03:46,400 --> 00:03:53,760 and then finally let's talk about this cooler shall we 54 00:03:51,519 --> 00:03:57,920 most consumer graphics cards and a lot of the previous mining cards use 55 00:03:55,439 --> 00:04:02,159 inexpensive horizontally oriented fans designed for use in an atx style 56 00:03:59,840 --> 00:04:07,200 computer case or an open-air mining chassis this works great for the home 57 00:04:04,799 --> 00:04:12,799 gamer or casual crypto miner but that style requires extra space for 58 00:04:10,080 --> 00:04:17,359 the cooler to operate properly so it's not really ideal for large-scale crypto 59 00:04:14,879 --> 00:04:21,199 mining so borrowing from the data center playbook the 60 00:04:18,440 --> 00:04:26,320 cmp-170hx removes the fans from the card all together and orients the fins for 61 00:04:24,080 --> 00:04:29,520 lengthwise airflow you throw a couple blowing metrons on the end and you no 62 00:04:28,080 --> 00:04:33,360 longer need to space them out you can just pack them right in which can vastly 63 00:04:31,919 --> 00:04:39,360 increase density that's awesome for crypto people but for 64 00:04:36,080 --> 00:04:41,040 me or rather for Jake it meant spending 65 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 66 00:04:43,440 --> 00:04:49,680 compatible server chassis lying around that we aren't already using in our 67 00:04:47,520 --> 00:04:55,280 server room um we opted to design a little 3d printed 68 00:04:52,560 --> 00:05:00,639 shroud that can take a 120 millimeter fan and then direct all of the airflow 69 00:04:58,639 --> 00:05:06,400 down this slot which we're going to use these included thumb screws to bolt onto 70 00:05:03,039 --> 00:05:08,800 the back of it and uh yeah we're gonna 71 00:05:06,400 --> 00:05:12,479 just zip tie the fan to the thing if for whatever reason you end up buying 72 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 73 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 74 00:05:17,440 --> 00:05:24,320 is uh an industrial ppc from Noctua that runs at 3000 RPM and does some pretty 75 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 76 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 77 00:05:31,360 --> 00:05:36,800 take this puppy apart you strip it already a little 78 00:05:35,280 --> 00:05:40,639 really okay so what is 79 00:05:38,400 --> 00:05:44,240 what cool boy 80 00:05:42,560 --> 00:05:50,400 oh boy whoa it's what 81 00:05:45,919 --> 00:05:53,280 it's fake black what what the heck 82 00:05:50,400 --> 00:05:55,759 is it now hold on just a gosh darn minute here 83 00:05:54,720 --> 00:05:59,919 okay so what they put aluminum 84 00:05:58,720 --> 00:06:04,240 heatsink here and here for looks they put these 85 00:06:04,319 --> 00:06:11,840 is that even metal this one's not connected to anything this appears to 86 00:06:08,960 --> 00:06:17,280 actually be for looks holy crap this thing is freaking jank Jake 87 00:06:14,880 --> 00:06:24,000 look at this oh they just like low-key 88 00:06:20,720 --> 00:06:27,759 solder the pci express connector to the 89 00:06:24,000 --> 00:06:30,000 freaking contact pads on the board here 90 00:06:27,759 --> 00:06:34,479 what yeah that's weird is it like that on the cards with the 91 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 92 00:06:36,960 --> 00:06:43,120 the power connector at the end oh i'm sure they could have clearly 93 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 94 00:06:44,319 --> 00:06:51,360 actually got one two three sets of envy link fingers 95 00:06:49,680 --> 00:06:56,479 uh hold on does this does this come out of here what the f 96 00:06:54,160 --> 00:07:00,000 hey language there are minors there are minors watching this video yeah get it 97 00:06:59,280 --> 00:07:03,000 yeah yeah 98 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 99 00:07:08,160 --> 00:07:16,720 oh god whoa that is a freaking expensive just like 100 00:07:14,240 --> 00:07:20,960 cosmetic piece of freaking aluminum men maybe i'm missing something but it looks 101 00:07:18,639 --> 00:07:28,560 to me like NVIDIA started with a freaking hunk of aluminum this thick and 102 00:07:24,160 --> 00:07:30,400 just milled away 90 of it for no reason 103 00:07:28,560 --> 00:07:34,639 other than to just have a beautiful cosmetic backplate on a GPU that nobody 104 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 105 00:07:36,880 --> 00:07:44,400 same piece that would have ended up on an a100 i know different etched so like 106 00:07:41,199 --> 00:07:46,319 that's an 11 000 card but still why 107 00:07:44,400 --> 00:07:49,680 yeah yeah it's just for looks you can see they've reused at least certain 108 00:07:48,000 --> 00:07:54,000 aspects of the consumer board design because they've got that uh kind of the 109 00:07:52,160 --> 00:07:58,800 weird fan cut out for the notch pass-through 110 00:07:55,520 --> 00:08:00,960 uh pass-through cooling i think the a100 111 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 112 00:08:02,400 --> 00:08:06,879 taking one apart i mean should we take the copper cooler off oh hell yeah yeah 113 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 114 00:08:08,960 --> 00:08:13,280 fingerprints on the copper the edges 115 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 116 00:08:21,120 --> 00:08:26,319 god oh okay yeah 117 00:08:24,560 --> 00:08:29,840 it's thermal epoxy the whole thing the whole GPU 118 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 119 00:08:32,000 --> 00:08:37,440 it's not worth it i'm sorry Jake we can't 120 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 121 00:08:40,320 --> 00:08:45,440 actually no 122 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 123 00:08:46,880 --> 00:08:52,000 patient stick the plastic thing right in there and then twist 124 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 125 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 126 00:08:58,720 --> 00:09:06,080 heat gun help to get off a thermal compounded thing 127 00:09:03,200 --> 00:09:09,920 probably but you should just grip it i like his style it's five grand well 128 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 129 00:09:11,680 --> 00:09:17,680 it i can try a twist i want a glove oh my goodness i'm not 130 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 131 00:09:20,880 --> 00:09:27,519 it um no i tried he wouldn't let me okay oh 132 00:09:24,399 --> 00:09:28,399 wow that was easy jesus christ holy 133 00:09:27,519 --> 00:09:33,440 oh that is a waiting it has an ihs on it 134 00:09:30,880 --> 00:09:37,680 GPU yeah it does what the hell i need some alcohol should you see this 135 00:09:35,360 --> 00:09:42,480 it hasn't it's freaking enormous it has an ihs 136 00:09:39,279 --> 00:09:47,360 holy i know 137 00:09:42,480 --> 00:09:49,440 oh what is it so it's ga 100-45f 138 00:09:47,360 --> 00:09:53,760 it looks like the lasering was done using two different processes probably 139 00:09:51,600 --> 00:09:58,320 at two separate times weird that's really weird does an a100 have an ihs i 140 00:09:56,320 --> 00:10:02,640 would think so because as far as we can tell they've just reused just about 141 00:10:00,320 --> 00:10:07,519 everything about the a100 for this card so the sxm cards don't 142 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 143 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 144 00:10:14,320 --> 00:10:20,399 whatever reason no idea because nobody's ever taken well they 145 00:10:18,000 --> 00:10:24,160 can put a bigger cooler on the PCIe version so maybe they need the more 146 00:10:22,399 --> 00:10:27,760 efficient thermal transfer for the other ones because that's why they did away 147 00:10:26,480 --> 00:10:32,720 with the other ones are way higher wattage well again then 148 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 149 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 150 00:10:39,120 --> 00:10:46,800 PCIe connector here this is hand soldered for sure 151 00:10:44,880 --> 00:10:49,720 why so it's a different kind of memory on 152 00:10:48,079 --> 00:10:55,760 this card you see you don't see any gddr6x or anything like that right this 153 00:10:52,320 --> 00:10:57,519 is all power delivery all around the GPU 154 00:10:55,760 --> 00:11:01,839 and then there's nothing on the back that's because all the memory is going 155 00:10:59,680 --> 00:11:06,399 to be under this heat spreader right next to the die and there's only eight 156 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 157 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 158 00:11:14,959 --> 00:11:20,800 higher bandwidth hence the name high bandwidth memory hbm 159 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 160 00:11:22,880 --> 00:11:28,800 its way into gaming cards except when from when AMD experimented with it for 161 00:11:26,959 --> 00:11:33,839 one generation i think maybe two so the GPU code name in this NVIDIA dock all 162 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 163 00:11:36,200 --> 00:11:44,640 100-400 or something like that um but yeah this is 105f 164 00:11:41,839 --> 00:11:47,839 weird very weird i hope this thing still works 165 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 166 00:11:49,360 --> 00:11:56,560 middle because these black fins are not connected to anything yeah and this back 167 00:11:54,320 --> 00:11:59,440 plate is not connected to anything like thermally 168 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 169 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 170 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 171 00:12:11,440 --> 00:12:18,079 know they do they just don't hold anything they don't serve a purpose 172 00:12:15,279 --> 00:12:21,040 other than to enclose the copper fins so that our 173 00:12:19,200 --> 00:12:23,120 clamps yeah together exactly that's all they do 174 00:12:22,240 --> 00:12:27,120 okay well hey are we ready to throw this bad 175 00:12:25,279 --> 00:12:30,800 boy on here oh man ha ha 176 00:12:28,880 --> 00:12:34,480 script calls for hydration v2 LTT water bottles now with quad 177 00:12:32,880 --> 00:12:39,200 channel memory LTT Store.com you ready to fire that up 178 00:12:36,480 --> 00:12:43,680 uh i'm putting more tape i like tape oh yeah so 179 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 180 00:12:46,160 --> 00:12:52,000 seal your duck here it goes 181 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 182 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 183 00:13:01,760 --> 00:13:08,320 the crazy part is this is like value compared to the product it's based 184 00:13:06,480 --> 00:13:13,360 on well the one it's based off of depending on the price is around like 11 185 00:13:10,240 --> 00:13:14,720 000 us 12 000 us 186 00:13:13,360 --> 00:13:19,519 it also has 5 to 10 times as much hbm2e i don't know 187 00:13:17,440 --> 00:13:23,920 how much the 80g ones are i don't know yeah probably more yeah 188 00:13:21,760 --> 00:13:27,279 now this is interesting a card that is not present on NVIDIA's 189 00:13:26,079 --> 00:13:32,480 website cannot have drivers downloaded from 190 00:13:29,760 --> 00:13:34,480 NVIDIA's website in fact this entire cmp series 191 00:13:33,440 --> 00:13:37,680 is not here nope not it's not under c-class 192 00:13:36,880 --> 00:13:43,839 either um so we end up on 193 00:13:41,160 --> 00:13:50,079 viperatec's website where we can go to mining gpus here it is NVIDIA 194 00:13:46,680 --> 00:13:52,880 cmp-170hx Windows drivers and we tried 195 00:13:50,079 --> 00:13:58,000 you cannot use the regular g-force or studio drivers with this card they just 196 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 197 00:13:59,760 --> 00:14:05,680 you can download from like MSI's website for the the lower end cmp cards 198 00:14:04,079 --> 00:14:10,800 oh crazy it doesn't even show up as a display 199 00:14:07,680 --> 00:14:12,160 adapter it's a 3d video controller 200 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 201 00:14:14,959 --> 00:14:21,600 thing in Windows that's true this is crazy 202 00:14:18,880 --> 00:14:25,360 so this mining specific driver we just downloaded still has like GeForce 203 00:14:23,600 --> 00:14:28,560 experience and stuff yeah and you can use it with like 30 series cards it's 204 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 205 00:14:30,720 --> 00:14:38,320 it with a 30 series which we have yeah 206 00:14:34,560 --> 00:14:41,440 30 90 for comparison this is so weird 207 00:14:38,320 --> 00:14:43,120 crap obs crashed while the NVIDIA driver 208 00:14:41,440 --> 00:14:46,079 was installing that makes sense wait why aren't we sleeping in nbank on it ben 209 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 210 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 211 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 212 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 213 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 214 00:15:08,399 --> 00:15:13,480 yeah rtx 39 told you i told ya 215 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 216 00:15:29,279 --> 00:15:34,480 like 3d engine going crazy i wonder if 217 00:15:32,639 --> 00:15:38,399 it's like a weird pass-through thing where like the mining card 218 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 219 00:15:42,959 --> 00:15:49,600 more thinking it's like the like on a 30 90 you can pick you want 220 00:15:47,199 --> 00:15:54,240 the GPU core or the end bank cord to do the encoding maybe 221 00:15:51,440 --> 00:15:58,000 okay let's try setting it to GPU too start recording oh 222 00:15:56,160 --> 00:16:01,680 you've selected GPU to set this back to zero and try again all right then 223 00:16:00,240 --> 00:16:07,440 so it doesn't work okay well that's weird because the data 224 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 225 00:16:10,320 --> 00:16:18,000 then yeah here we go gpuz does not know this graphics device 226 00:16:15,040 --> 00:16:21,120 yet this is an entirely new one guys good job help the community by 227 00:16:19,759 --> 00:16:25,120 submitting a validation for the fourth tab heck yeah well we'll start with that 228 00:16:23,680 --> 00:16:29,279 my name sinus labastian 229 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 230 00:16:32,720 --> 00:16:40,880 let's have a look at this thing then technology unknown die size unknown 231 00:16:38,480 --> 00:16:45,360 release date unknown transistors unknown 232 00:16:42,160 --> 00:16:51,360 oh now this is fascinating whoa is that 233 00:16:45,360 --> 00:16:53,360 1.1 it uses a PCIe 1.1 by 4 interface 234 00:16:51,360 --> 00:16:57,360 now hold on a second that may not be quite 235 00:16:55,279 --> 00:17:00,720 right because even though it might be at that link speed now 236 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 237 00:17:03,519 --> 00:17:07,839 still pci 1.1 yeah 1.1 238 00:17:06,880 --> 00:17:12,559 huh that's really interesting now to be 239 00:17:10,240 --> 00:17:16,160 clear for mining there's not actually much data transfer that takes place over 240 00:17:14,400 --> 00:17:19,919 the pci express connection you're just sending the GPU work it's churning 241 00:17:18,319 --> 00:17:24,160 through it and it's sending you back a result that's it so 242 00:17:21,679 --> 00:17:29,280 there's no reason i guess for NVIDIA to enable the full pci express gen 4x16 243 00:17:27,360 --> 00:17:33,200 link that this GPU would otherwise be capable of in fact there's reason for 244 00:17:31,280 --> 00:17:36,640 them to not that makes it harder for people to potentially repurpose this as 245 00:17:34,960 --> 00:17:40,480 a card that could do other things even if they could get through any driver 246 00:17:38,720 --> 00:17:45,280 locks that NVIDIA has put in place which nobody ever would when NVIDIA puts a 247 00:17:42,720 --> 00:17:48,880 driver lock in place it stays there what are they up to like seventy percent 248 00:17:47,200 --> 00:17:52,480 efficiency on the low hash rate card seventy one percent everyone hilarious 249 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 250 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 251 00:17:59,280 --> 00:18:06,480 we've got hbm2 memory with a 252 00:18:03,080 --> 00:18:06,480 4096-bit bus 253 00:18:06,600 --> 00:18:12,960 1493 gigabytes per second of memory bandwidth 254 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 255 00:18:16,480 --> 00:18:21,760 something like that and the a100 bandwidth is higher that's 256 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 257 00:18:24,240 --> 00:18:31,919 under a terabyte a second clocked at 1140 boosts to 1410 same 258 00:18:28,799 --> 00:18:34,320 boost as an a100 no NVIDIA sli higher 259 00:18:31,919 --> 00:18:39,760 bass clark interestingly you've been talking a lot about directx oh 260 00:18:37,039 --> 00:18:43,280 uh directx support unknown go to advanced i think there's you can like 261 00:18:41,760 --> 00:18:47,120 try it general power limit okay directx 9 try 262 00:18:46,320 --> 00:18:49,520 that device 263 00:18:50,000 --> 00:18:57,679 could not initialize interesting so if you were hoping to 264 00:18:54,480 --> 00:19:00,480 grab one of these and make your own 265 00:18:57,679 --> 00:19:03,200 cloud gaming service you know obviously well it doesn't have an HDMI connection 266 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 267 00:19:07,280 --> 00:19:12,240 compute cards for purposes like that you will not be doing it on this one it 268 00:19:10,960 --> 00:19:18,080 supports cuda well okay and oh interesting not vulcan 269 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 270 00:19:19,840 --> 00:19:24,400 it's frozen oh wow yeah it's really locked up then 271 00:19:22,960 --> 00:19:27,919 okay you try optics it does have tensor cores 272 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 273 00:19:31,360 --> 00:19:37,039 it's trying to do nothing so the clock speed goes up 274 00:19:34,960 --> 00:19:40,320 but the GPU temperatures actually don't change it's just still not doing 275 00:19:39,039 --> 00:19:45,760 anything is that the base clock yeah i think so yeah it's just a base 276 00:19:43,120 --> 00:19:49,280 huh all its base are belong to us i think blender is just telling it to 277 00:19:47,360 --> 00:19:54,799 switch power states gear it up to do work that it will then never do yeah 278 00:19:51,760 --> 00:19:55,840 this is a giant disappointment so far 279 00:19:54,799 --> 00:20:00,480 i mean only because we got our hands on a 280 00:19:58,080 --> 00:20:06,080 mining GPU and wanted to do something else on it a 5 000 mining GPU 281 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 282 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 283 00:20:11,440 --> 00:20:18,400 tuning yet it hit boost clock for a second and then it dialed back a little 284 00:20:15,280 --> 00:20:20,799 bit how's our power 245 watts temps are 285 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 286 00:20:22,320 --> 00:20:29,120 memory speed you can't do really anything the only thing you can adjust 287 00:20:26,559 --> 00:20:32,240 is the power limit which we should do because when i was messing around with 288 00:20:30,320 --> 00:20:38,240 it earlier by default it draws 250 watts and mines like 164 289 00:20:36,159 --> 00:20:44,480 mega hash in ethereum but if you turn it down to like 80 it 290 00:20:40,480 --> 00:20:46,000 does 160 mega hash at 200 watts which is 291 00:20:44,480 --> 00:20:50,880 way more efficient you're barely losing anything oh wow all right there we go oh 292 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 293 00:20:52,720 --> 00:20:59,200 core clock but let's not i give the community not that long to 294 00:20:57,360 --> 00:21:04,000 figure out how to change more stuff on these things it's hard with NVIDIA cards 295 00:21:01,039 --> 00:21:06,240 wow look at that 200 watts and 296 00:21:06,559 --> 00:21:12,240 the memory tips in the 30 90 are just ripping 297 00:21:10,320 --> 00:21:16,400 wow look at that i guess that's one advantage to having 298 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 299 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 300 00:21:22,400 --> 00:21:28,720 in temp between the hbm2e and the GPU 301 00:21:25,440 --> 00:21:33,200 so the 30 90 is 275 kilohash a watt and 302 00:21:28,720 --> 00:21:35,600 sorry what is the cmp 840 800 303 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 304 00:21:36,960 --> 00:21:44,960 get like around 850. so like yeah that's insane mind you a 305 00:21:43,039 --> 00:21:50,080 tuned 30 90 you could probably get around 400 kilohash a lot 306 00:21:47,520 --> 00:21:54,400 it's still double double and that's with us tuning it in like 307 00:21:52,559 --> 00:22:00,640 four seconds 372. we could definitely get to 400 308 00:21:56,240 --> 00:22:02,640 kilohaw i'm sure how can this be 309 00:22:00,640 --> 00:22:08,000 40 to 50 faster than the top-tier GeForce GPU and 310 00:22:06,320 --> 00:22:12,880 double the efficiency while on the same ampere architecture 311 00:22:10,240 --> 00:22:16,559 yeah it's crazy okay let's talk about that there are a number 312 00:22:14,480 --> 00:22:21,200 of reasons but the main one is likely memory bandwidth the ethereum mining 313 00:22:18,559 --> 00:22:26,480 algorithm et hash is almost entirely bottlenecked by memory bandwidth so if 314 00:22:23,280 --> 00:22:28,480 you have an approximately 50 memory 315 00:22:26,480 --> 00:22:33,360 bandwidth difference and that correlates to a 40 to 50 performance difference 316 00:22:31,679 --> 00:22:37,360 that mostly checks out as for the power draw 317 00:22:35,120 --> 00:22:42,159 while they are based on the same ampere architecture the a100 silicon is 318 00:22:39,760 --> 00:22:44,960 manufactured on tsmc's seven nanometer process 319 00:22:43,120 --> 00:22:48,640 rather than samsung's eight nanometer process which is what's used on the 30 320 00:22:46,640 --> 00:22:52,640 series gaming cards that's going to help you on efficiency for sure 321 00:22:50,640 --> 00:22:56,960 so there's no doubt that this is a killer piece of hardware for crypto 322 00:22:54,799 --> 00:23:00,159 miners but there are still a couple of questions left to answer 323 00:22:58,640 --> 00:23:04,640 with the looming proof-of-stake migration for ethereum on the horizon 324 00:23:01,919 --> 00:23:09,840 does it make sense to buy a pricey card that at current profitability could take 325 00:23:06,640 --> 00:23:11,919 about a year to pay itself off and has 326 00:23:09,840 --> 00:23:16,240 zero value whatsoever outside of mining crypto 327 00:23:13,280 --> 00:23:19,280 well if NVIDIA's shortfall in cmp business unit revenues are anything to 328 00:23:18,320 --> 00:23:26,000 go by most people think probably not reselling old mining cards 329 00:23:24,000 --> 00:23:30,640 is one of the ways that miners will recoup their costs in the event of a 330 00:23:27,600 --> 00:23:32,080 crash or a legislative change i'll let 331 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 332 00:23:35,200 --> 00:23:41,520 then that cmp products would not affect 333 00:23:38,559 --> 00:23:45,679 the shortages of gaming products because they would not be redirecting silicon 334 00:23:43,360 --> 00:23:51,200 that could have ended up in a gaming GPU and in this instance it actually does 335 00:23:48,320 --> 00:23:57,600 appear that there's validity to NVIDIA's claims this GPU is clearly compute only 336 00:23:54,799 --> 00:24:02,159 with no meaningful gaming utility though the same cannot necessarily be said of 337 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 338 00:24:04,320 --> 00:24:10,960 the future whether you've been thinking
