samples of their processors even exist and yet here i am in a video sponsored by Intel holding nothing other than a golden sample and it gets even better because Intel sent over a second very special package a cryogenic cooler that they claim can be used to chill a chip like their golden sample to sub-ambient temperatures and help it reach frequencies as high as 5.6 to 5.8 gigahertz in gaming workloads and it gets even better again because we've got a stream coming up where you'll get a chance to win one of these combo packs you will find more details linked below you know i don't know what's up with like this scrappy new attitude over at Intel but i like it let's go for a test drive ladies and gentlemen CPU go brrrr on the surface there's nothing unusual about the core i9 10 900k inside this golden foil wrapper 10 cores 20 threads 3.7 gigahertz base 5.3 gigahertz max boost etc etc etc but on the inside is a piece of silicon that was hand picked by Intel's engineers as a shining example of the absolute best their 14 nanometer process is capable of now these kits were actually created for ltx this year hence the packaging but it's just as well because a little more time in the kitchen has turned into a far more interesting experience let's shift our focus for a moment then to what the heck is a cryo cooler there are two partners that Intel worked with to develop these things cooler master created this a pre-filled aio style unit while ek went the custom loop route the ek solution is actually what we used in our fastest gaming pc in the world for now video and that's how we were gaming at 5.4 gigahertz with all cores so let's start with an unboxing of this puppy first things first you've got a triple radiator so far nothing especially cryo looking about that three 120 millimeter fans it's all pretty normal we've got uh actually what looks like a pretty beefy pump especially for an aio like it's nothing for like a custom loop but that looks fairly considerable all right that's uh kind of non-standard connection on there and then ah now this this is where the magic happens inside the CPU block is a custom thermoelectric cooling or tech module that draws about 200 watts of power using an 8-pin pci express power connector for the uninitiated tech cooling takes place when an electric current passes through a thermocouple causing heat to be absorbed on one side and then to be output on the other side the more powerful the peltier the more cooling you get but also the more heat you have to deal with hence the need for a triple radiator now on a normal CPU only aio cooler like the Corsair one that i'm pulling out of this system a triple rad is kind of overkill on the cryo cooler it's pretty much a necessity as we're going to see and there are some other considerations you probably noticed that even though the cooler master master liquid ml360 sub-zero has a separate pump the CPU block unit is too large to account for just adding a thermoelectric cooling module in there that's because there's a shroud to prevent humid air from contacting the cold surface here there's a freaking humidity sensor to help manage condensation yes my friends and there's a power control and monitoring board that communicates with Intel's cryo cooler software it's not the greatest mount for the pump but i did manage to kind of screw it into the top of a fan it's more intended for like a slit like this or an empty 120 millimeter fan mount where you could just put the thumb screws through the mount into the like threaded bracket but hey it's on there y'all want to go sub zero with me we've already applied the BIOS update that we're going to need for the cryo cooler so all that's left is to throw on our xmp profile and fire up Windows in order to avoid any potential for bottlenecks this system is loaded up with 5100 megahertz RAM from crucial as well as an rtx 3090 that's actually on its own completely separate water cooling loop so Intel told me to expect temps as low as minus 10 degrees celsius in unregulated mode but recommended sticking with cryo mode for daily driver operation cryo mode uses CPU telemetry data to avoid unnecessary power draw and tells the cryo cryocooler if something's improperly mounted or something Intel did mention that only 10th and 11th gen and onward cpus are designed to provide that feedback although technically you could use the cryo cooler with anything you wanted as long as you made the necessary modifications to the condensation shroud yolo now let's talk about another thing Intel's been cooking up called oc thermal velocity boost regular thermal velocity boost already existed and it's just a higher level of turbo frequency that your CPU can gear up into when it's running cool enough it's the oc part that's new so get this in a highly unusual move is that competition i smell Intel is adding this feature to existing silicon with a microcode update allowing users to adjust the factory thresholds for thermal velocity boost using their xtu overclocking utility all right so why don't we have a look at the software first of all there's the cryo software which is very simple okay so there's standby cryo and unregulated i mean should we just fool around with unregulated mode first and see what kind of temps we see oh we're down to 60 wait 43 degree what is it doing 10 degrees what's going on here Intel it's definitely working these wires right here that go from the top of the unit where the power goes in down to presumably where the tech is yeah down at the base these are warm and our CPU temps are looking pretty interesting as well check this out we've already dropped down to zero degrees celsius now it's not letting me go below zero degrees which is interesting i would guess because of the climate that we're in and the local humidity yeah dew point nine point eight and the cooler is actually at minus ten now let's pull out the old thermal camera and have a quick lookie boo here you can see the warm cable everything up here is pretty cool pretty normal looking radiator's not super toasty oh interesting we can see the hot side of our tech module through this grille here and then we can actually see how chilly things are right around the CPU socket that's actually one of the bigger concerns with running in unregulated mode not necessarily that you're going to get condensation on the cooler itself because you've got that little shroud on it to keep warm air away from it but rather that the board itself might have air going across it that is going to cause condensation so we can see this even more clearly around the back that is freaking chilly well below ambient temps now let's have a look at the interface niklas already ran some before numbers both with the CPU running at stock speeds as well as with his own sort of conservative attempt at using thermal velocity boost overclocking but Intel sent me over what they call a starting point recipe for our golden chip that they're hoping will give us 5.6 or maybe even 5.8 gigahertz in games it's not the most user friendly thing ever 56 multiplier dang that feels crazy to even put in 4 core 56 so then 55 and then 54 so they want 5.4 gigahertz all core 5.6 4 core well we applied it oh yeah any voltage things oh i need 1.45 volts adaptive turbo boost short max power should be good my understanding is this is a very new feature whoopsie daisies well that's what you get for not um changing all your voltage settings and stuff before overclocking to 5.6 gigahertz good luck everybody apply is it running faster oh yes it is definitely i saw it boost past 5.3 for a second there idle temps look good right in that 12 13 degree range about 5 degrees below ambient temperature right now all right thank you for the coil wine rtx 3090 love you okay oops whoops oh bloody hell we're one round in let's tab out and what did we see in here 5.4 max okay do we want to try a more extreme recipe might as well okay okay everything else here is the same we're just going for 5.7 on loads up to you know what no forget it 5.8 up to two cores 5.7 up to four see if you know golden sample one of 200 can do it start with 1.475 volts okay uh let's do 485 yeah we definitely have cores that are seeing 5.5 gigahertz uh i'm pretty sure this is more performance we're seeing anywhere from 370 to 380 i'm even touching 390 FPS from time to time it might just be working highest clock speed seen 5.5 gigahertz throughout that run but every core touched it whoa hey now that we're out of game we just saw 5.7 gigahertz on three of the cores what that tells us then is that counter-strike global offensive is more like a five to six core load at least with whatever we've got running in the background which frankly isn't much other than our monitoring tools so what i'm going to do now then given that that is stable is nicholas is going to run us through all the benchmarks that he ran before and we'll get you that comparative data the results are in and this is fascinating guys we ended up needing about 1.5 volts to reach 5.7 gigahertz and this is a real lesson in optimizing your overclock because more voltage means of course more heat and especially combined with the extra 200 watts from our tech that's a lot for even a triple radiator to manage so in cs go for example we actually got our best result from nicholas's lighter overclock at a lower voltage you can see that his 99th percentile frames so that's the slowest one percent of frames that the system is outputting we're actually about 10 faster with cryo cooling but not pushed to the limit do maternal on the other hand shows us exactly what this kind of cooling is capable of in a best case scenario going from a stock CPU on a triple water cooler all the way up to 5.7 gigahertz we went from 184 to 222 FPS even if it did ultimately end up running about 20 degrees hotter than the conservative more lightly overvolted attempt as for shadow of the tomb raider it didn't end up being particularly CPU limited in general so this shows us a really good mix of games that will either benefit a little bit in certain situations benefit a ton or potentially not benefit at all of course a few more FPS in lightly threaded loads like games isn't going to mean much if the whole thing falls apart when you fire up a workload that exceeds the 230ish watt limit of the cryo cooler block so uh does it fall apart over the course of an extended test we found that while our system performance was on par with a regular triple aio our temps were significantly higher which is a bit of a downer considering that a cryo cooler is expected to cost about twice as much as a regular aio cooler with that said not everybody runs extended all core loads and it should be noted that this is a very first generation attempt from talking to Intel about it the cryo-cooler initiative is actually less of a random one-off project by a handful of nerdy engineers than i expected although it should be noted the engineers were undoubtedly delightfully nerdy and they consider it to be more of a first step towards helping mainstream users achieve the kind of off-the-wall frequencies that they'd normally only see from hardcore overclockers now the timing of Intel's interest in squeezing extra performance out of their near redline flagship CPU is definitely a little suss as the kids say but for my part i'm not one to look a gift horse in the mouth and in my opinion the enthusiast community should support initiatives like this in hopes that we see more of them on the subject of support that was one area that i told Intel i would like to see them do better the reason traditional overclocking you know where you just set an all-core ratio and increase the CPU voltage is still so popular is because it's simple this kind of overclocking where you're setting individual core frequencies under various loads and at various temperature thresholds with various offsets is not simple and one of the biggest challenges is validation with a normal all core overclock it's easy to tell if the system is stable you just run a stress test overnight and see if it errors out but if Intel wanted this to get to the point where let's say a puget systems or origin pc is going to ship a pre-overclocked cryo gaming pc to a customer they need to create the tools that will help test single dual multi-core workloads with and without avx offsets etc etc etc and simultaneously monitor die temps power use frequency and stability that way everyone from a system integrator to an end user can know with confidence that if they get a blue screen down the road it's because of a driver update or something and not because their CPU flew too close to the sun so bottom line i am enthused to see more dials for enthusiasts to play with and very excited to see where the road map for coolers based on this tech leads us pun definitely intended if you enjoyed this video maybe check out one of our previous attempts at sub-zero cooling i'll tell you guys this is significantly more elegant and quieter"}
