WEBVTT 00:00:00.240 --> 00:00:07.440 these two computers have the exact same specifications which means their 00:00:04.560 --> 00:00:13.920 performance is exactly the same right wrong when we tested the Corsair one 00:00:10.139 --> 00:00:16.859 A200 we noticed some fishy results so we 00:00:13.920 --> 00:00:21.600 built a near exact replica except for the case motherboard radiator and memory 00:00:19.220 --> 00:00:26.400 and don't you worry we'll explain why the memory is different later then we 00:00:23.640 --> 00:00:31.380 ran the same benchmarks and I'm pretty sure the results will surprise you 00:00:28.800 --> 00:00:36.180 No actually that's a lie I am completely sure the results will surprise you but 00:00:34.440 --> 00:00:39.660 won't surprise you is this message from our sponsor glassware are you worried 00:00:38.340 --> 00:00:43.920 that someone else is using your Wi-Fi glasswire can alert you anytime a new 00:00:42.059 --> 00:00:48.860 device joins so use offer code Linus to get 25 off glassware at the link in the 00:00:46.260 --> 00:00:48.860 video description 00:00:55.879 --> 00:01:02.879 our Corsair 1a200 boasts impressive 00:00:59.399 --> 00:01:06.600 specs it's got an AMD 5900x 12 core CPU 00:01:02.879 --> 00:01:08.700 a full fat RTX 3080 GPU one terabyte of 00:01:06.600 --> 00:01:14.460 NVMe storage with two terabytes of hard drive-based storage and 32 gigs of 3200 00:01:12.060 --> 00:01:19.439 megahertz RAM all in this Nifty little case with separate 170 and 240 00:01:17.760 --> 00:01:25.920 millimeter all-in-one liquid coolers for each the CPU and the GPU wait 170 00:01:23.759 --> 00:01:29.939 millimeter well should be better than 120 at least so then 00:01:28.560 --> 00:01:35.880 what the heck is up with this performance I mean to be clear 60 FPS in 00:01:33.360 --> 00:01:42.479 Shadow of the Tomb Raider at 4K with RTX enabled is a lot of performance but the 00:01:38.939 --> 00:01:45.180 Corsair 1a200 also costs a lot of money 00:01:42.479 --> 00:01:50.340 so I expect it to leave absolutely nothing on the table and something 00:01:47.340 --> 00:01:53.119 smells a little funny here 00:01:50.340 --> 00:01:53.119 you smell that 00:01:53.460 --> 00:02:01.079 it smells like heat it's going up my nose 00:01:57.860 --> 00:02:04.079 ah there's your problem despite this 00:02:01.079 --> 00:02:07.560 machine being liquid cooled it's CPU 00:02:04.079 --> 00:02:09.840 idles at around 50 degrees and check 00:02:07.560 --> 00:02:14.520 this out just about the second you put it under any kind of load with a print 00:02:11.940 --> 00:02:21.239 screen and this paint and we're going to paste this you're gonna see it's 00:02:17.160 --> 00:02:24.239 actually jumped a full 10 degrees 00:02:21.239 --> 00:02:28.500 just since I took the screenshot 00:02:24.239 --> 00:02:31.200 what even is that and get this rcpu 00:02:28.500 --> 00:02:36.000 never saw the Max rated boost speed of 4.8 gigahertz throughout our testing I 00:02:33.840 --> 00:02:41.040 mean it is important to note that AMD's fine print specifies that that is a 00:02:38.340 --> 00:02:47.700 single core boost speed but still seeing 4.8 gigahertz on the box and only 00:02:43.860 --> 00:02:50.340 actually seeing 4.5 in games and 4.0 in 00:02:47.700 --> 00:02:56.220 cinebench can be very confusing to the average user especially when I'm pretty 00:02:53.340 --> 00:02:59.580 sure that this chip can do better and we're not the only ones experiencing 00:02:57.540 --> 00:03:05.400 issues we've found a few posts on Corsair's Forum discussing poor thermals 00:03:01.739 --> 00:03:08.160 on the 5900x and 5950x equipped models 00:03:05.400 --> 00:03:14.220 it's not surprising considering how small form factor builds do tend to run 00:03:10.800 --> 00:03:16.019 harder but it's certainly not ideal the 00:03:14.220 --> 00:03:20.640 thing is though many modern computers are actually designed to run at or near 00:03:19.080 --> 00:03:24.239 their thermal limits without it significantly impacting their 00:03:22.140 --> 00:03:28.980 performance so the only way for us to know just how much this is hindering us 00:03:26.760 --> 00:03:33.319 is to build up another machine to compare and thanks to movie Magic 00:03:40.620 --> 00:03:45.620 foreign 00:03:45.620 --> 00:03:54.000 this one is already done she's a chunky boy but 00:03:50.940 --> 00:03:56.879 spec for spec this sucker is identical 00:03:54.000 --> 00:04:01.319 to our Corsair 1a200 except for a couple things as I mentioned before we used a 00:03:59.700 --> 00:04:07.620 different motherboard to match our case size and our 3200 megahertz memory 00:04:04.739 --> 00:04:13.080 actually had to be manually adjusted to be slower to match the loose timings on 00:04:10.319 --> 00:04:18.900 the RAM included with the one and since we don't have a 170 millimeter red we 00:04:15.900 --> 00:04:23.460 went with a 240 since 120 is definitely not enough during a 10 minute stress 00:04:21.060 --> 00:04:28.979 test running cinebench R23 the Corsair one reached a sweltering peak of 90 00:04:26.520 --> 00:04:35.280 degrees Celsius running at just over 4 gigahertz meanwhile our clone here with 00:04:32.040 --> 00:04:37.440 a similar Corsair mind you 240 00:04:35.280 --> 00:04:44.460 millimeter radiator ended up in the mid 70s at just over 4.1 gigahertz that's a 00:04:40.740 --> 00:04:48.060 difference of just over 15 degrees 00:04:44.460 --> 00:04:50.400 but the thing is that clock speed Delta 00:04:48.060 --> 00:04:56.400 doesn't fully explain the performance that I feel like is missing here what 00:04:53.639 --> 00:05:02.400 else is going on in both of our systems the RTX 3080 gpus easily reached their 00:04:59.820 --> 00:05:07.620 maximum boost clock of 1950 megahertz and maintained nearly identical average 00:05:05.400 --> 00:05:12.960 clock speeds throughout our testing but while our air cooled car barely 00:05:10.560 --> 00:05:18.960 pushed past 60 degrees running shadow of the Tomb Raider maxed out the liquid 00:05:15.180 --> 00:05:21.780 cooled Corsair one peaked at over 70 in 00:05:18.960 --> 00:05:26.580 the same test now 70 degrees under load is fine for a GPU and it's clear from 00:05:25.020 --> 00:05:32.820 the narrow two and a half percent difference in results that 80 degrees on 00:05:29.039 --> 00:05:34.320 the CPU is also fine that is if you 00:05:32.820 --> 00:05:38.400 don't mind trading two and a half percent of your performance for a super 00:05:36.419 --> 00:05:42.720 gorgeous and compact design like this one but hold on a second 00:05:40.320 --> 00:05:47.759 not all games behave the same take a look at CS go yeah yeah sure both 00:05:45.479 --> 00:05:53.039 machines manage around 600 frames per second so you're going to be having a 00:05:49.620 --> 00:05:56.479 pretty good time but that is a six 00:05:53.039 --> 00:05:59.280 percent difference in raw performance so 00:05:56.479 --> 00:06:03.960 it's clear that the more CPU bottlenecked our application is the more 00:06:01.560 --> 00:06:09.479 the Corsair ones borderline cooling system is likely to affect it 00:06:06.240 --> 00:06:11.580 and this Rabbit Hole goes even deeper 00:06:09.479 --> 00:06:17.960 yeah man I thought this was just going to be a simple system review 00:06:14.039 --> 00:06:19.740 that makes sad Linus even sadder Linus 00:06:17.960 --> 00:06:25.560 lttstore.com we actually built our clone system here 00:06:22.139 --> 00:06:27.960 with a fatal flaw watch as we transform 00:06:25.560 --> 00:06:30.380 it into a system that performs even better 00:06:49.979 --> 00:06:52.979 dude 00:06:54.680 --> 00:07:00.180 holy hot monkey bananas going back to CS 00:06:58.560 --> 00:07:05.880 go here there's something I didn't mention last time average FPS not really 00:07:04.139 --> 00:07:11.880 a great indication of the gaming experience because you don't notice 00:07:09.120 --> 00:07:17.759 animation smoothness when it's good you notice it when it sucks that's why a CPU 00:07:15.000 --> 00:07:22.979 that's thermal throttling at all is such a problem as it speed fluctuates you'll 00:07:20.460 --> 00:07:27.900 experience extremely short but sometimes drastic dips in performance and we can 00:07:26.819 --> 00:07:33.180 measure those so looking at the worst one percent of 00:07:30.479 --> 00:07:38.940 our frame times our clone here beat the Corsair one by almost 15 right out of 00:07:36.060 --> 00:07:46.319 the gate and our upgraded clone takes that lead to almost 20 percent just for 00:07:43.440 --> 00:07:54.060 adding a bigger radiator I mean the Corsair one is still over 300 FPS so all 00:07:50.699 --> 00:07:56.039 right no problem in this game but these 00:07:54.060 --> 00:07:59.639 effects can be measured and more importantly felt in other situations as 00:07:58.620 --> 00:08:05.160 well let's take a look at cinebench our clone 00:08:02.880 --> 00:08:10.139 with the Dual radiator performed nearly identically to our course R1 but all of 00:08:07.979 --> 00:08:14.099 a sudden we throw a triple Radiator in and it manages a three percent advantage 00:08:12.360 --> 00:08:20.280 over both of them this is probably because our 12 core 00:08:16.440 --> 00:08:23.220 5900x is right at the limit of what a 00:08:20.280 --> 00:08:28.020 dual 120 millimeter AIO can handle so bringing that coolant temperature down 00:08:25.259 --> 00:08:33.360 lets the CPU opportunistically boost up higher and more often 00:08:30.360 --> 00:08:36.240 of course this raises the question why 00:08:33.360 --> 00:08:41.279 is it so hard for a 170 millimeter radiator to cool a CPU That's rated at 00:08:38.219 --> 00:08:43.320 just 105 Watts TDP when a slightly 00:08:41.279 --> 00:08:48.480 larger Radiator on the other side of the same computer is cooling a GPU That's 00:08:45.480 --> 00:08:50.160 rated at 320 Watts that's over double 00:08:48.480 --> 00:08:56.100 well there's a couple of reasons for this first is that the die of the GPU 00:08:52.920 --> 00:08:58.920 like this one is much larger and more 00:08:56.100 --> 00:09:03.540 surface area means more thermal transfer second GPU coolers are pre-installed at 00:09:01.980 --> 00:09:09.180 the factory where they can be placed directly that's a pun on the GPU itself 00:09:07.200 --> 00:09:13.680 rather than having a heat spreader in between our die lapping Adventure video 00:09:11.339 --> 00:09:18.779 by the way is a great look at just how many degrees you can literally shave off 00:09:16.320 --> 00:09:22.200 with a steady hand and some risky work now some of you have probably noticed 00:09:20.459 --> 00:09:26.820 I've been very focused on thermal differences between our systems here it 00:09:24.779 --> 00:09:33.180 is possible that the power delivery on the ASRock b550 Phantom gaming ITX AC is 00:09:30.180 --> 00:09:35.399 holding us back but given that our 00:09:33.180 --> 00:09:40.440 performance continues to improve by going to a bigger radiator it looks like 00:09:37.740 --> 00:09:45.120 thermals are the culprit and in any case it changes nothing about this machine 00:09:42.300 --> 00:09:50.760 costing 400 dollars more than Corsair's own similarly equipped Vengeance a 7200 00:09:47.700 --> 00:09:53.040 while underperforming compared to what 00:09:50.760 --> 00:09:59.220 the hardware is capable of I mean we poked at some ideas to fix the 00:09:55.920 --> 00:10:01.800 one A200 we updated the BIOS we tried 00:09:59.220 --> 00:10:06.120 undervolting with one osmus's tool which resulted in hard crashes we tried tuning 00:10:04.260 --> 00:10:11.279 the fan curve although that gave us some really funky behavior that doesn't seem 00:10:08.100 --> 00:10:13.500 to be isolated to our unit and I mean 00:10:11.279 --> 00:10:16.920 I don't know we could reapply a high quality thermal paste or Put liquid 00:10:15.180 --> 00:10:24.240 metal on it or something but the thing is this is a pre-built For Better or For 00:10:21.300 --> 00:10:28.560 Worse most people are not going to do any of that stuff and it should just 00:10:26.940 --> 00:10:33.420 work out of the box and besides some people might not even 00:10:31.620 --> 00:10:38.580 care about the trade-off they're making maybe for you form means more than 00:10:36.060 --> 00:10:43.440 function and the courser rate 200 might be worthwhile from your perspective I 00:10:41.040 --> 00:10:47.160 mean it still is a downright sexy machine that uses standardized Parts 00:10:45.060 --> 00:10:51.660 which allows you to upgrade it down the line if you're so inclined it's just 00:10:49.320 --> 00:10:55.560 that I do think that Corsair should revise the case in cooling design if 00:10:54.180 --> 00:10:59.040 they're going to keep packing it with the latest and greatest Hardware going 00:10:57.420 --> 00:11:02.880 forward just like I'm going to keep packing this
