WEBVTT 00:00:00.160 --> 00:00:07.120 for years Intel has discouraged the notion that golden samples of their 00:00:04.000 --> 00:00:10.719 processors even exist and yet 00:00:07.120 --> 00:00:14.160 here i am in a video sponsored by Intel 00:00:10.719 --> 00:00:14.160 holding nothing other than 00:00:15.120 --> 00:00:23.119 a golden sample and it gets even better because Intel 00:00:19.520 --> 00:00:27.039 sent over a second very special package 00:00:23.119 --> 00:00:29.840 a cryogenic cooler that they claim can 00:00:27.039 --> 00:00:33.600 be used to chill a chip like their golden sample to sub-ambient 00:00:31.920 --> 00:00:42.160 temperatures and help it reach frequencies as high as 5.6 to 5.8 00:00:38.719 --> 00:00:44.559 gigahertz in gaming workloads and 00:00:42.160 --> 00:00:48.000 it gets even better again because we've got a stream coming up where you'll get 00:00:46.320 --> 00:00:54.079 a chance to win one of these combo packs you will find 00:00:51.600 --> 00:00:58.399 more details linked below you know i don't know what's up with like this 00:00:56.079 --> 00:01:05.879 scrappy new attitude over at Intel but i like it let's go for a test drive 00:01:00.879 --> 00:01:05.879 ladies and gentlemen CPU go brrrr 00:01:13.600 --> 00:01:20.799 on the surface there's nothing unusual about the core i9 10 900k inside this 00:01:19.119 --> 00:01:28.720 golden foil wrapper 10 cores 20 threads 3.7 gigahertz base 00:01:24.640 --> 00:01:32.159 5.3 gigahertz max boost etc etc etc but 00:01:28.720 --> 00:01:35.119 on the inside is a piece of silicon that 00:01:32.159 --> 00:01:40.560 was hand picked by Intel's engineers as a shining example of the absolute best 00:01:38.400 --> 00:01:46.399 their 14 nanometer process is capable of now these kits were 00:01:43.520 --> 00:01:50.320 actually created for ltx this year hence the packaging 00:01:48.560 --> 00:01:55.520 but it's just as well because a little more time in the kitchen has turned into 00:01:52.320 --> 00:01:57.520 a far more interesting experience 00:01:55.520 --> 00:02:02.399 let's shift our focus for a moment then to what the heck is a cryo cooler there 00:02:00.479 --> 00:02:09.039 are two partners that Intel worked with to develop these things cooler master 00:02:04.880 --> 00:02:11.920 created this a pre-filled aio style unit 00:02:09.039 --> 00:02:16.239 while ek went the custom loop route the ek solution is actually what we used in 00:02:14.000 --> 00:02:21.760 our fastest gaming pc in the world for now video and that's how we were gaming 00:02:18.480 --> 00:02:23.440 at 5.4 gigahertz with all cores 00:02:21.760 --> 00:02:27.760 so let's start with an unboxing of this puppy 00:02:25.200 --> 00:02:33.840 first things first you've got a triple radiator so far nothing especially cryo 00:02:30.879 --> 00:02:39.519 looking about that three 120 millimeter fans it's all pretty normal we've got uh 00:02:37.440 --> 00:02:43.840 actually what looks like a pretty beefy pump especially for an aio like 00:02:42.239 --> 00:02:48.080 it's nothing for like a custom loop but that looks fairly considerable 00:02:46.480 --> 00:02:51.599 all right that's uh kind of non-standard connection on there 00:02:50.400 --> 00:02:53.920 and then ah 00:02:55.120 --> 00:03:03.440 now this this is where the magic happens 00:02:59.599 --> 00:03:06.560 inside the CPU block is a custom 00:03:03.440 --> 00:03:09.519 thermoelectric cooling or tech module 00:03:06.560 --> 00:03:13.040 that draws about 200 watts of power using an 8-pin pci express power 00:03:11.920 --> 00:03:17.760 connector for the uninitiated tech cooling takes 00:03:15.519 --> 00:03:22.400 place when an electric current passes through a thermocouple causing heat to 00:03:19.840 --> 00:03:27.040 be absorbed on one side and then to be output on the other side the more 00:03:24.800 --> 00:03:32.319 powerful the peltier the more cooling you get but also the more heat you have 00:03:30.000 --> 00:03:37.920 to deal with hence the need for a triple radiator now on a normal CPU only aio 00:03:36.239 --> 00:03:41.840 cooler like the Corsair one that i'm pulling out of this system 00:03:39.760 --> 00:03:47.280 a triple rad is kind of overkill on the cryo cooler 00:03:45.360 --> 00:03:51.519 it's pretty much a necessity as we're going to see 00:03:49.200 --> 00:03:55.680 and there are some other considerations you probably noticed that even though 00:03:53.280 --> 00:04:02.159 the cooler master master liquid ml360 sub-zero has a separate pump the CPU 00:03:58.879 --> 00:04:04.159 block unit is too large to account for 00:04:02.159 --> 00:04:08.799 just adding a thermoelectric cooling module in there that's because there's a 00:04:06.560 --> 00:04:13.200 shroud to prevent humid air from contacting the cold surface here there's 00:04:11.120 --> 00:04:18.720 a freaking humidity sensor to help manage condensation yes my friends and 00:04:16.320 --> 00:04:22.720 there's a power control and monitoring board that communicates with Intel's 00:04:20.560 --> 00:04:25.919 cryo cooler software it's not the greatest mount for the pump but i did 00:04:24.240 --> 00:04:32.479 manage to kind of screw it into the top of a fan it's more intended for 00:04:28.400 --> 00:04:33.919 like a slit like this or an empty 120 00:04:32.479 --> 00:04:38.720 millimeter fan mount where you could just put the thumb screws through the 00:04:36.080 --> 00:04:43.360 mount into the like threaded bracket but hey it's on there y'all want to go sub 00:04:41.520 --> 00:04:47.759 zero with me we've already applied the BIOS update that we're going to need for 00:04:44.720 --> 00:04:50.400 the cryo cooler so all that's left is to 00:04:47.759 --> 00:04:56.000 throw on our xmp profile and fire up Windows in order to avoid any potential 00:04:53.759 --> 00:05:00.560 for bottlenecks this system is loaded up with 00:04:56.759 --> 00:05:03.040 5100 megahertz RAM from crucial as well 00:05:00.560 --> 00:05:06.160 as an rtx 3090 that's actually on its own completely separate water cooling 00:05:04.639 --> 00:05:12.160 loop so Intel told me to expect temps as low as 00:05:08.800 --> 00:05:15.280 minus 10 degrees celsius in unregulated 00:05:12.160 --> 00:05:17.840 mode but recommended sticking with cryo 00:05:15.280 --> 00:05:22.720 mode for daily driver operation cryo mode uses CPU telemetry data to avoid 00:05:20.479 --> 00:05:26.560 unnecessary power draw and tells the cryo cryocooler if something's 00:05:24.080 --> 00:05:31.360 improperly mounted or something Intel did mention that only 10th and 11th gen 00:05:29.120 --> 00:05:35.680 and onward cpus are designed to provide that feedback although technically you 00:05:33.919 --> 00:05:38.960 could use the cryo cooler with anything you wanted as long as you made the 00:05:37.280 --> 00:05:43.440 necessary modifications to the condensation shroud yolo 00:05:41.919 --> 00:05:47.520 now let's talk about another thing Intel's been cooking up called oc 00:05:45.680 --> 00:05:51.919 thermal velocity boost regular thermal velocity boost already 00:05:49.759 --> 00:05:56.880 existed and it's just a higher level of turbo frequency that your CPU can gear 00:05:54.240 --> 00:06:01.120 up into when it's running cool enough it's the oc part that's new 00:05:59.919 --> 00:06:05.039 so get this in a highly unusual move 00:06:05.280 --> 00:06:12.720 is that competition i smell Intel is adding this feature to existing 00:06:10.479 --> 00:06:18.880 silicon with a microcode update allowing users to adjust the factory thresholds 00:06:16.160 --> 00:06:24.639 for thermal velocity boost using their xtu overclocking utility 00:06:22.639 --> 00:06:29.280 all right so why don't we have a look at the software first of all there's the 00:06:26.960 --> 00:06:35.039 cryo software which is very simple okay so there's standby cryo 00:06:32.319 --> 00:06:38.319 and unregulated i mean should we just fool around with unregulated mode first 00:06:36.800 --> 00:06:42.880 and see what kind of temps we see oh we're down to 60 wait 43 degree what is 00:06:40.960 --> 00:06:47.680 it doing 10 degrees what's going on here Intel it's definitely working 00:06:45.280 --> 00:06:52.400 these wires right here that go from the top of the unit where the power goes in 00:06:49.919 --> 00:06:56.880 down to presumably where the tech is yeah down at the base these are warm and 00:06:55.280 --> 00:07:01.120 our CPU temps are looking pretty interesting as well check this out we've 00:06:58.960 --> 00:07:06.080 already dropped down to zero degrees celsius now it's not letting me go below 00:07:03.680 --> 00:07:11.280 zero degrees which is interesting i would guess because of the climate that 00:07:08.560 --> 00:07:15.840 we're in and the local humidity yeah dew point nine point eight and the cooler is 00:07:13.599 --> 00:07:19.840 actually at minus ten now let's pull out the old thermal camera and have a quick 00:07:17.520 --> 00:07:23.360 lookie boo here you can see the warm cable 00:07:21.120 --> 00:07:27.919 everything up here is pretty cool pretty normal looking 00:07:24.800 --> 00:07:28.840 radiator's not super toasty 00:07:27.919 --> 00:07:34.880 oh interesting we can see the hot side of 00:07:31.840 --> 00:07:37.039 our tech module through this grille here 00:07:34.880 --> 00:07:41.039 and then we can actually see how chilly things are right around the CPU socket 00:07:39.520 --> 00:07:44.720 that's actually one of the bigger concerns with running in unregulated 00:07:43.120 --> 00:07:48.880 mode not necessarily that you're going to get condensation on the cooler itself 00:07:46.880 --> 00:07:53.680 because you've got that little shroud on it to keep warm air away from it but 00:07:51.120 --> 00:07:58.479 rather that the board itself might have air going across it that is going to 00:07:55.680 --> 00:08:02.879 cause condensation so we can see this even more clearly around the back that 00:08:01.199 --> 00:08:06.720 is freaking chilly 00:08:04.240 --> 00:08:11.360 well below ambient temps now let's have a look at the interface niklas already 00:08:08.879 --> 00:08:16.080 ran some before numbers both with the CPU running at stock speeds as well as 00:08:14.080 --> 00:08:20.800 with his own sort of conservative attempt at using thermal 00:08:18.080 --> 00:08:25.680 velocity boost overclocking but Intel sent me over what they call a 00:08:22.879 --> 00:08:30.960 starting point recipe for our golden chip that they're hoping will give us 00:08:27.520 --> 00:08:32.479 5.6 or maybe even 5.8 gigahertz in games 00:08:30.960 --> 00:08:39.279 it's not the most user friendly thing ever 56 multiplier 00:08:35.919 --> 00:08:43.919 dang that feels crazy to even put in 4 00:08:39.279 --> 00:08:47.160 core 56 so then 55 and then 54 so they 00:08:43.919 --> 00:08:51.200 want 5.4 gigahertz all core 00:08:47.160 --> 00:08:51.200 5.6 4 core 00:08:51.600 --> 00:08:59.200 well we applied it oh yeah any voltage things oh i need 1.45 volts adaptive 00:08:57.279 --> 00:09:02.880 turbo boost short max power should be good 00:09:00.399 --> 00:09:06.480 my understanding is this is a very new feature 00:09:04.800 --> 00:09:10.560 whoopsie daisies well that's what you get for not um 00:09:09.040 --> 00:09:14.480 changing all your voltage settings and stuff before overclocking to 5.6 00:09:12.720 --> 00:09:18.640 gigahertz good luck everybody 00:09:16.480 --> 00:09:23.600 apply is it running faster oh 00:09:20.720 --> 00:09:28.640 yes it is definitely i saw it boost past 5.3 for a second there idle temps look 00:09:26.320 --> 00:09:32.240 good right in that 12 13 degree range about 5 degrees below ambient 00:09:30.640 --> 00:09:38.959 temperature right now all right thank you for the coil wine rtx 3090 love you 00:09:35.839 --> 00:09:40.640 okay oops whoops oh bloody hell we're 00:09:38.959 --> 00:09:46.399 one round in let's tab out and what did we see in 00:09:42.399 --> 00:09:48.080 here 5.4 max okay do we want to try a 00:09:46.399 --> 00:09:52.160 more extreme recipe might as well okay 00:09:50.560 --> 00:09:58.320 okay everything else here is the same we're just going for 5.7 on loads up to 00:09:55.360 --> 00:10:03.600 you know what no forget it 5.8 up to two cores 5.7 up to four see if you know 00:10:00.880 --> 00:10:10.800 golden sample one of 200 can do it start with 1.475 volts okay 00:10:08.160 --> 00:10:15.200 uh let's do 485 yeah we definitely have cores that are 00:10:12.399 --> 00:10:19.120 seeing 5.5 gigahertz uh i'm pretty sure this is more performance we're seeing 00:10:16.959 --> 00:10:23.200 anywhere from 370 to 380 i'm even touching 00:10:20.040 --> 00:10:27.040 390 FPS from time to time it might just 00:10:23.200 --> 00:10:29.519 be working highest clock speed seen 5.5 00:10:27.040 --> 00:10:33.440 gigahertz throughout that run but every core touched it whoa hey now that we're 00:10:32.320 --> 00:10:38.640 out of game we just saw 5.7 gigahertz on three of 00:10:36.480 --> 00:10:43.680 the cores what that tells us then is that counter-strike global offensive is 00:10:40.800 --> 00:10:47.440 more like a five to six core load at least with whatever we've got running in 00:10:45.440 --> 00:10:51.519 the background which frankly isn't much other than our monitoring tools so what 00:10:49.040 --> 00:10:55.040 i'm going to do now then given that that is stable 00:10:52.720 --> 00:10:58.640 is nicholas is going to run us through all the benchmarks that he ran before 00:10:56.800 --> 00:11:03.680 and we'll get you that comparative data the results are in and this 00:11:00.959 --> 00:11:10.640 is fascinating guys we ended up needing about 1.5 volts to reach 5.7 gigahertz 00:11:07.440 --> 00:11:12.800 and this is a real lesson in optimizing 00:11:10.640 --> 00:11:17.680 your overclock because more voltage means of course more heat and especially 00:11:15.680 --> 00:11:23.040 combined with the extra 200 watts from our tech that's a lot for even a triple 00:11:20.160 --> 00:11:28.160 radiator to manage so in cs go for example we actually got our best result 00:11:25.200 --> 00:11:33.360 from nicholas's lighter overclock at a lower voltage you can see that his 99th 00:11:30.880 --> 00:11:37.519 percentile frames so that's the slowest one percent of frames that the system is 00:11:35.200 --> 00:11:42.720 outputting we're actually about 10 faster with cryo cooling but not pushed 00:11:40.399 --> 00:11:48.160 to the limit do maternal on the other hand shows us exactly what this kind of 00:11:45.839 --> 00:11:53.120 cooling is capable of in a best case scenario going from a stock CPU on a 00:11:51.279 --> 00:11:59.600 triple water cooler all the way up to 5.7 gigahertz we went from 184 to 00:11:57.240 --> 00:12:04.399 222 FPS even if it did ultimately end up running 00:12:01.600 --> 00:12:09.440 about 20 degrees hotter than the conservative more lightly overvolted 00:12:07.279 --> 00:12:14.160 attempt as for shadow of the tomb raider it didn't end up being particularly CPU 00:12:11.519 --> 00:12:18.560 limited in general so this shows us a really good mix of games that will 00:12:16.399 --> 00:12:23.519 either benefit a little bit in certain situations benefit a ton 00:12:21.040 --> 00:12:27.120 or potentially not benefit at all of course 00:12:24.720 --> 00:12:30.720 a few more FPS in lightly threaded loads like games isn't going to mean much if 00:12:29.279 --> 00:12:36.079 the whole thing falls apart when you fire up a workload that exceeds the 00:12:33.079 --> 00:12:38.880 230ish watt limit of the cryo cooler 00:12:36.079 --> 00:12:42.959 block so uh does it fall apart over the course of an 00:12:41.120 --> 00:12:47.440 extended test we found that while our system performance was on par with a 00:12:45.440 --> 00:12:52.800 regular triple aio our temps were significantly higher 00:12:50.399 --> 00:12:57.600 which is a bit of a downer considering that a cryo cooler is expected to cost 00:12:54.800 --> 00:13:02.639 about twice as much as a regular aio cooler with that said not everybody runs 00:13:00.399 --> 00:13:07.760 extended all core loads and it should be noted that this is a very 00:13:05.519 --> 00:13:12.320 first generation attempt from talking to Intel about it the cryo-cooler 00:13:09.519 --> 00:13:16.720 initiative is actually less of a random one-off project by a handful of nerdy 00:13:14.320 --> 00:13:20.639 engineers than i expected although it should be noted the engineers were 00:13:18.160 --> 00:13:24.800 undoubtedly delightfully nerdy and they consider it to be more of a first step 00:13:22.720 --> 00:13:28.560 towards helping mainstream users achieve the kind of off-the-wall frequencies 00:13:26.959 --> 00:13:33.120 that they'd normally only see from hardcore overclockers now the timing of 00:13:30.720 --> 00:13:38.160 Intel's interest in squeezing extra performance out of their near redline 00:13:35.120 --> 00:13:41.120 flagship CPU is definitely a little suss 00:13:38.160 --> 00:13:44.480 as the kids say but for my part i'm not one to look a gift horse in the mouth 00:13:42.720 --> 00:13:48.800 and in my opinion the enthusiast community should support initiatives 00:13:46.399 --> 00:13:53.440 like this in hopes that we see more of them on the subject of support that was 00:13:51.360 --> 00:13:57.760 one area that i told Intel i would like to see them do better the reason 00:13:55.920 --> 00:14:03.920 traditional overclocking you know where you just set an all-core ratio and increase the 00:14:01.040 --> 00:14:08.720 CPU voltage is still so popular is because it's simple 00:14:06.240 --> 00:14:13.120 this kind of overclocking where you're setting individual core frequencies 00:14:11.040 --> 00:14:16.480 under various loads and at various temperature thresholds with various 00:14:14.959 --> 00:14:22.399 offsets is not simple and one of the biggest 00:14:19.199 --> 00:14:24.800 challenges is validation with a normal 00:14:22.399 --> 00:14:28.720 all core overclock it's easy to tell if the system is stable you just run a 00:14:26.800 --> 00:14:32.160 stress test overnight and see if it errors out but if Intel wanted 00:14:31.279 --> 00:14:36.160 this to get to the point where let's say a 00:14:34.399 --> 00:14:40.720 puget systems or origin pc is going to ship a 00:14:38.000 --> 00:14:44.399 pre-overclocked cryo gaming pc to a customer 00:14:41.839 --> 00:14:49.440 they need to create the tools that will help test single dual multi-core 00:14:47.040 --> 00:14:55.120 workloads with and without avx offsets etc etc etc and simultaneously monitor 00:14:52.880 --> 00:14:58.000 die temps power use frequency and stability 00:14:56.320 --> 00:15:01.760 that way everyone from a system integrator to an end user can know with 00:14:59.920 --> 00:15:06.240 confidence that if they get a blue screen down the road it's because of a 00:15:04.240 --> 00:15:09.519 driver update or something and not because their CPU flew too close to the 00:15:08.240 --> 00:15:16.240 sun so bottom line i am enthused to see more dials for 00:15:13.480 --> 00:15:21.040 enthusiasts to play with and very excited to see where the road map for 00:15:18.079 --> 00:15:25.440 coolers based on this tech leads us pun definitely intended 00:15:23.680 --> 00:15:28.959 if you enjoyed this video maybe check out one of our previous attempts at 00:15:26.959 --> 00:15:35.880 sub-zero cooling i'll tell you guys this is significantly more 00:15:31.680 --> 00:15:35.880 elegant and quieter
