Yes mom, I need an AMD Threadripper Pro 7995WX CPU to compile my C code for school
😅
The Code: int main(){ printf("Hello World")}; 🤣🤣🤣🤣
But it compiles super fast🤣
And few 4090TI too... for Excel and stuff.
Probably for compiling hello.c?
"How powerful is your CPU"
"A bit over a horsepower"
"Oh that's~ a bit over a what???"
If you could spray those electrons out of a fire hose, it would be like getting kicked by a horse.
1 horse power is roughly 750 watts. So a bit over 1 horsepower.

Soon the EPA will mandate a _MIPS per Watt_ sticker on processors.
😆
At ~10W per core, this CPU isn't doing all that bad even in its overclocked state. Some Intel CPUs will happily exceed that at stock settings.
And then the manufacturers will redefine "mips."
10w per core is not too bad, considering my 12900HX (8p+8e) can use ~115w sustained power.
Well, good! Heat is pretty much a dead limit, and bigger coolers only give diminishing returns. So if there's a heat limit, less heat per core means more cores, and cores are computers and computers are good!
If Americans paid for petrol what the rest of the world does, this perverse pride they take in wasting the stuff would disappear quick-smart.
Yes, we did teach a rock to think, but not to oversimplify; first you have to flatten the rock and put lightning inside of it.

@@MOSMASTERING I'm a little surprised that Dave didn't spring for a chiller. Given the machine was twenty grand, another few kilodollars for a real chiller isn't unrealistic.
@@BinkyTheToaster
Haha.. Kilodollars, I like it.
Given the increase in prices in just about everything right now, I'm assuming kilodollars are how I'll be describing my weekly grocery shop...
I think he mentioned something about this being as loan CPU for testing, so probably isn't allowed to screw with it too much.
I'm upgrading my studio computer at the end of this year and I can't get a straight answer from anyone about what chip would serve me best, audio processing is an extremely unusual set of variables split between single core power and threads. I posted here in the hope Dave might find a way of doing benchmarks for audio type stuff..
@@MOSMASTERING that's true about the "loaner cpu." I was just thinking that the chiller would give the cores a bit more thermal overhead to run the clocks higher than what a simple closed-loop 420 would allow.
I'm hoping to do a PCVR rig by EoY if only to cram it into an InWin POC (the green/yellow, it's total cyberpunk), but I want the video feed coming out the top USB/Displayport and I'm not sure how to rig a card to do that.
Define "a rock" what is it composed of? Can it process? What are the properties? These are important things!
PBO is an AMD overclocking thing invented by amd. Asus has a custom config (just like other mobo's)for it but its totally amd's tech
Damned Anton!
@@DavesGarage Anton should have flipped a coin and call it out.
For reference, that (correctly) addresses 11:01
You have to use AMD's PBO and not ASUS' PBO as one works great (AMD's one) and the other will probably lower your performance!
@@Traumatreeno, the motherboard ones can and will kill your chip on auto.
Jeff Geerling needs one of these, he is always compiling the kernel.
He has the ARM Ampere version that goes up to 128 cores. It's not pulling 1000W though.
Love the 1+ Horsepower analysis!
No matter how you look at it, 1000W is basically a space heater, and moving that much heat that fast is a hard task.
I'm glad you do this sort of things so we don't have to :)
Hey, thanks for sharing your C++ game dev course. Was a bit outside my scope, but still watched it for a few hours. Was really interesting, even for someone not quite ready in terms of programming skill. Really generous of you to share that as a resource.
@@420bobby69Glad you enjoyed it :)
Except heaters do it every day with micro electronics built inside . Imagine that
@DaveChurchill Don't have to or can't afford to.
@@KC-nd7ntHeating elements are not made of nano-scale transistors, they can afford to store a lot of heat while it slowly moves throughout a room
Back in the day, you had a heater and no computer.
Then you had a computer and a heater.
Nowadays, your computer *is* your heater
I remember they said people you should save electricity. You can do more with it but it gets more and more and more.... And here the price for that goes up and up and...😅
it's funny just how effective mine is at heating my room. if my psu wasnt crap, i could uncap my fps in games and my room would be a "cool" texas summer at 90f. capped, i've measured it at 84-5
I used to run a VAX at home.. that idea of your computer being your heater has been around for quite a while... 🙂
Exactly. My smallest room has no heating but a 13700 system.
@@c128stuffBack in the day, we had VAXes at Uni. Unobtainable for us mere mortals. Then, recently, I saw a vid on YT from some showing the inner workings of a VAX. A board for CPU, one for RAM, I/O etc. mounted on a back-plane. I thought: I can do this. Then he showed the backside of the back-plane with a tangle of yellow wires which needed to be configured to your setup. That's when my confidence waned. When I saw the power plug, I knew: Even if I could buy such a system, and even I I could configure it, the electricity bill would kill me.
Your channel size is irrelevant, Dave. We are here because we know that you have a great wealth of knowledge and experience in this field - creating components of operating systems that most of us have used! Clearly your sponsors know too!
Thanks for the video and sharing these beasts with us. If I could pair one with a 4090 I would definitely need to have my PC setup on two different circuits in my house.
@@roncaruso931to think I turned down the Microsoft offer in 1995.
@@c1ph3rpunk Yes!! I give Dave all the credit. He deserves what he has. He worked hard.
That motherboard & processor will support 7 4090's each with 16 PCIe lanes. Not sure about the power supply. 7 RTX 4090's are also cheaper than a pair of RTX 6000 Ada GPU's
@@nathanbanks2354 Just checked the 4090 FE, it scores ~34000 pulling 290W in Cinebench 2024. The catch with the desktop cards is their physical size is bigger so you couldn't fit them in the case.
Nice space heater 👌🏻
I thought my Gigabyte Windforce Radeon R9 290 made a great space heater back when I had one of those! HA!
I actually run computers as heaters.
I actually run folding@home overnight, don't need the central heating any more.
11:02 Anton the editor is incorrect. Precision Boost Overdrive is an overclocking mode found on all ryzen based systems from 3000 series onward and is part of the default UEFI implementation provided by AMD to it's partners. For a couple of easy examples, I have asus, gigabyte, and asrock boards currently in service in my house right now with various ryzen 3000 and 5000 series cpus that all support PBO.
oh boy...I have my morning tea in hand....ready for another video ride Dave! Thanks for posting!
We are lucky to have him here. Sharing cutting-edge technology with us. Clear and concise communication, illustrations, history, and information. We couldn't get any ware else in such a master who walks his talk. 😊
Soon, you can keep your tea heated with the CPU
4:30 Dave I suggest running folding@home if you ever want to run multi gpu tests and look at the points per hour calculation and test the entire system
Can be tricky though as not all work units scale to more CUDA cores, though admittedly its seems a lot rarer lately to get a WU that doesn't.
He’s been a Plumber for a year decades now 😂😂😂😂😂😂😂 Nice one Dave, I see what you did there.
8:14 Dave (or anyone for that matter!) should probably have a look at Mold, it's a modern drop-in replacement for the GNU/GCC and LLVM linkers and it takes advantage of multiple cores. It's a bit dark wizardry, but it works amazingly well. Can't imagine how fast it would link huge project binaries on a 7995WX :-)
It would be something that needs to get stable and adopted by the projects first, because thats what matters. you'd need to check if the final program with that linker is as well optimized etc
"I haven't read Microprocessor report since branch prediction was a new thing" what a wonderful quote!!! And it was a wonderful publication!
Very well researched, written, presented, and produced! Great job, Dave :)
I'm really enjoying your videos, Dave.. excellent presentations, man...
So the Chromium browser is bigger than the Linux kernel? That surprised me.
It shouldn't. Linux for how diverse it gets is a very tightly run ship for the core components.
Google... is Google. Chromium has become an absolutely sprawling monolith akin to a full blown os.
These days browsers are operating systems by themselves.
It's been sometime since I cared about the main processor but your presentation made the instantiation of these new threadrippers into a new light!
That looked like a clip from "Running on empty" a classic. Nice work again mate, loved every minute of it.
Tip top content once again...appreciate the effort... We all know you do this out of love - and we LOVE it!
First, love the video! The absurdity of just taking a 96 core threadripper and turning on PBO is amazing.
Second, I take minor issue with "you can only do 350W of work no matter the core counter". The energy efficiency of modern processors goes up dramatically when you slow them down. If you have enough work to keep 96 cores busy, 96 cores at 350W will do it a lot faster than 16 cores at 350W. That is assuming of course you have the IO to keep the 96 cores fed, which is not a small consideration. This threadripper is amazing is that it can effectively do both, it has a ton of cores for parallel work, and still has 5+GHz when the work gets single thready.
Third, minor suggestion. I am an AMD enthusiast and I'd like to suggest you explore undervolting. PBO has a setting called the Curve Optimizer and what it does is give you a voltage offset that scales with the CPU's standard voltage setting at any given speed. The brilliance here is you aren't dialing in a big change that you'd want at a higher clock speed all the time. Quick primer done, AMD chips today seem to love undervolting. I have a 5800X3D and I set a -30 curve offset, which made my CPU clock about 5% faster under a prime95 test load at the same power limit. 5% isn't massive at 8 cores, but it's basically free performance, and on 96 cores that might be an impressive jump.
Keep tinkering, I love this stuff. 🙂
Thanks! That's why I was careful to note that its not linear... not every watt is equal!
Yeah, 4.5Ghz for all 96 Cores is enough for desktop usage.
Even as workstation, were sustained workloads need some wiggle room for an all nighter 😁
Also, those extra cores will reduce the amount of context switching. Each one gets it's own L1 and L2, so you will have a higher hit rate.
I would expect some workloads to benefit a lot more from more cores.
Not sure why I wasn’t subbed in the past having watched a few vids here and there when they popped up In the feed. Great enjoyable content my dood!
Keep up the the great work!
Dave, power on! You've created and are maintaining a garage that exists in my dreams. Thanks for sharing.
Glad you got the samples to test and thanks for your eval. My wife is an elementary school special ed teacher and I got her your book for Christmas.
I have to say, this is my first time viewing your channel and I loved listening to your content, excellent presentation, very professional indeed. I'm an intel XEON fanboy too, really enjoyed the content. :D
This is the first time watching your channel really enjoyed this video. Thanks.
Glad you enjoyed it!
I love this channel. You are amazing at explaining things with great detail and as a bonus, you are playing with some cool toys too!
can't believe I've only just found your channel. at least I have found it now. thank you Dave I'll be here for every new video now I'm subscribed.
Excellent video, Cheers Dave
The uncore of these CPUs uses a lot of power. AnandTech did a really good write-up on older Threadripper processors which covered the high uncore power usage. My own old and 'lowly' TR2950X uses 35-45W for the uncore and 25-135W for the cores. The wider Infinity Fabric on the same generation of Epyc processors the uncore was 66-86W while core was 10-90W. Even disabling a lot of the cores still requires a lot of uncore power use.
High "uncore" is not just a threadripper problem. my motherboard wanted to get 1.2v into uncore of a 5600x, it runs rockstable with ~0.88 or so for me
They couldn't just call it "non-core", could they, the bunch of autists? Between the bionic hive-mind of the chip designers, and the monkeys on Macintoshes in marketing, that term somehow escaped out into the public. Even the smartest people are getting stupider.
@@Salzui Voltage is kind of irrelevant in that instance. The uncore of the 5600X is much smaller than on a Threadripper and uses a lot less power. You can use something like HWMonitor to see the core/uncore power use under Windows.
This is great! I've been trying to decide between buying an OEM and building a custom 7995WX system. This was exactly the data I needed.
Great video on the 7995WX.
"My name is Dave Engineer, a retired Operating System plummer!" Plus: I like the way you are literally buying time!
Threadripper's the reason that I got into custom water cooling. The only AIO that fully covered the TR was the Enermax cooler and people were complaining about them failing (the coolant turned to sludge). They've had a few revisions since then, so I don't know if they still have that issue or not.
yes they do. go heatkiller iv or similar, there are many choices but not enermax.
anyway if you do have an enermax, clean it and refill it with pure distilled water +1 drop each of Mayhems Inhibitor+ / Mayhems Biocide+ (or similar).
i think the problem is in the materials they used. i'll never touch enermax again
thanks for this bucketful knowledge you shared dave
Amazing video Dave!
I always wondered what it would look like if I were to do this. thanks!
Great video Dave!!
BRAVO!!! Thank you for the Engineering!
thank you for this awesome video dave
"when its allowed to run free and eat" Love it, because it is eating amps and spitting out watts! Thanks for leaving that in!
Given V-core is likely around 1.4v under load, we can guess that socket was pumping a bit over 700A into the CPU through all those little pins. I've welded with a lot less current that that.
Oh wow, I got my 14900k to pull 375 continuous... after about 5 mins the mo-bo became heat soaked and we blue screened... 1000w is wild!
Can I just say, the colour grading and quality of video seems immaculate... better than 90% of "professional" UA-cam channels..
Considering the amount of lights, RGB and various colours all around you - its all captured and reproduced fantastically.
I assume you know what you're doing with video encoding types. I haven't made videos in well over 15 years, so I'm totally out of touch with anything video related.
Very interesting stuff, Dave! I built my own system a couple of years ago. I didn't give myself a completely unlimited budget, but I didn't cheap out. Luckily, I did my research and kept everything in spec and made sure everything fit without modification. Thus, I've never had unstable performance or stability issues. I think that's the biggest takeaway from your video.
Excellent video as always. Did the homebrew prove to be stable in the longer term?
at around 8mins 50seconds that scanline shader or whatever it is, is magic to my eyes !!!! thanks
Right on. Thanks for sharing.
You Got It!
Great Video!!
Thank You!!
For an all in one watercooling system like this, I'd expect the maximum sustained dissipation to sit somewhere between 200-350W for a desktop CPU, possibly a bit more for this setup since the heatspreader is so enormous. For 1000W you basically need a custom loop with some MoRa external radiators or a waterchiller.
"For some reason or another, I could never get their RGB software working" - that's a very common occurance, it's amazing how all of these RGB software suites manage to be even worse than the next.
Great video by the way, you've gotten really good at these. Compare the way you're speaking now to some of your earliest videos, quite the difference.
You're seriously underestimating how much heat a small radiator can dissipate if you don't mind the water getting a bit toasty and the fans getting a bit noisy. Remember the >300W GPUs with a single 120mm radiator AIO for cooling? I do...
@@Steamrick I had some of those, yeah (6900XTXH LC). There are other issues aside from just the total amount of heat where radiator size can help you.
The quality of your waterblock matters a lot more at 500W+ than at 200W. At 1kW you should have a dedicated product and not something that is primarily designed for desktop platforms. The highest dissipation I cooled for prolonged amounts of time was with intel's skylake-x, where CPU-only I got to around 750W. To keep this from thermal throttling, I needed to run the best available block directly on the die instead of using the integrated heatspreader, since while my radiators could dissipate the heat, my block could not keep up with the additional layers between it and the core. At some point, you cannot buy a better waterblock anymore (or run into diminishing returns), but may still run into thermal throttling regardless even if you could theoretically dissipate enough heat via your radiators.
Once you reach that point, reducing your coolant temperature by having more surface area to work with (or using a water chiller) helps immensely with this issue. You'll also want a good pump or course!
Nice to see a channel where I can check in once in a while and see what the fastest PC in the world is like :)
Thanks Dave!
Great episode
Very cool. Yup on the Spectrum.
I’m thinking that one of the PDP 11’s might be able to compete on the thermal side of the challenge. I enjoy watching you working projects which go as far back as the PDP and Altair and as up to date as the Threadrippers. Of all my old PDP collection the only part I use on a regular basis is my old DEC coffee cup. Thanks.
This was very informative. Thank you for your excellent videos.
I wonder if the core count will continue to increase and eventually high-core-count processors will become a commodity.
I expect the technology will no longer be silicon by the time that happens, and the power requirements will be lower.
Epic video.
A custom water block with compression fittings and some proper rads/fans (dual d5 pumps) could probably shave alot more off that time.
Thank you for translating the wattage to horsepower. Finally the gap between my two greatest interests, since childhood, has been closed.
nVidia's latest Grace Hopper CAUs- possibly the most expensive silicon ever sold on the open market- can dissipate over 1kW of heat in operation.
That's awesome Dave! Can't afford a system like that yet but man, what a beast! Thinking maybe a 7960X non pro with more RAM than I have now (architecture / 3D rendering) would work.
PBO is an AMD technology, Asus just implements it on their motherboards. So Dave is correct.
More outtakes please Dave- genuinely funny!
Would love to see NiceHash CPU mining on XMRig using the RandomX as a benchmark. Would be fun to see how it compares and then you could also test the 100% workload how it affects the cooling system, which you did later in the video using other ways. Good job!
Now compiling chrome in under an hour, that’s a flex.
at 7:07 you said gpu when you meant cpu - amazing video as always!
Thank you!
i really wish i could build this system, awesome just awesome!
GOOD GREIF! I guess that's why I watch Dave.
"Run free and eat..." I love that! Now I have to look for opportunities to use it.
Surprised a guy like you Dave, didn't build a custom water loop. First time watching your channel. I miss Dos 6.0...starting to play with it in middle school.
Interesting and entertaining! It would make an excellent fan or radiator heater for winter; simple heaters do nothing but heat. The expense is a bit of a stopper for me. Then there is the question of what work I would really need it to do. That is impressive.
Awesome video! Loved the results and the custom machine for the 1kw tests. Only thing I would’ve changed on it is upgrade the PSU to a 1500-1600w (maybe more) one, might reduce the chance of crashes with the extra headroom since the cores are pulling 1kw with the CPU’s IO die pulling probably 100-150w plus the rest of the system, then the 1200w PSU isn’t up to snuff anymore. (I’m sure it can handle a bit of a overload, but not for 15-30 mins haha)
Might explain random spontaneous reboots.
I love these ultra high performance PC videos!
Just keep in mind that the Enermax Liqtech TR4 have had a lot of issues with corrosion and precipitation inside. Not sure if that has been fixed.
I was going to buy that motherboard just to enlarge my E-Penis, but I couldn't find any other justification to own one. So I settled for half a dozen Dell R610's and a server rack enclosure. I love the loud jet-like fan noise/heat emanating from them. It's absolute bliss when everything at home is powered 24/7 with solar panels and 45KW hours of lifepo4 batteries. Dave here too, but not a plumber - cheers from Texas
On the subject of custom watercooling - I'd always recommend steering clear of bending pipes (aka hard tubing) and go with industrial black ZMT instead. The compression fittings are foolproof and in 5 years I've had exactly 1 leak - and that was because I forgot to put a blanking plug into on of the ports on my GPU block.
So l ong as you also make sure to use the right tubing cutter, and also to lubricate the O ring seals insode the fittings as well before inserting the tube. Makes a big difference to them, especially at the larger sizes, and at the small end where those seals have very little leeway in them.
Those are some pretty cool space heaters Dave 😎
Gj, nice comparisons. I'm still struggling with delidding a 13700 since it's limited by the lid. A lid that just doesn't wanna break lose :D
That blooper was hilarious. Utterly bonkers performance on your custom build.
Really sweet. As I remember when dirt was invented, it's always good to see one of my generation rocking the absolute cutting edge kit.
Hope to live long enough to catch one of these chips that I could afford on the used market, maybe. I rather enjoy seeing what percentage of the latest and greatest with my outdated, used gear.
I think Dell (or one of the OEMs) just announced plans to accommodate a 1000w GPU from nVidia.
Maybe you'll have to revisit your 1000w CPU paired with whatever 1000w GPU seems to be in the pipeline?
Omg I'm jealous of the custom built you did. I could configure that sucker to run well. That 512gb of ddr5 5800 is no doubt putting the board traces to the test. You could completely get stability with 5200 m/ts. Good logic for figuring out the waterblock issue.
NOTHING is more satisfying that opening a well-built PC in terms of chassis quality and wire management.
Thank you, Dave, for always bringing us the relevant information that we need without all the frills and bullshit some channels dabble in. It's refreshing to find what's needed in the age of clickbait. Stay fresh and keep it real, Dave.
I've been using that case for several years for my 12900ks setup. It's a solid case.
Back in the early 1990s I bought a Sun 3/160 from a guy out in East Bay. I remember opening up the front of the cabinet and seeing the sticker “1.5 KW” on the power supply. Went straight to KW, no messing around with Watts. 😊
18:34 Everyone's gotta run free and eat sometimes 😂 Loved this video, Dave!
I wonder how long it will be before these kinds of setups are consider "old school" or "vintage". Amazing how far we have come.
Hey Dave, just so you know, your channel is NOT that small!! Kudos to get 3 of those beasts.. Shoot I'm excited I grabbed a 5800x3d (I play games on that machine) for 289 nib.. Oh well.
Very fun content Thank you.
Dave I just purchased a thermal contact plate for my Intel 13th gen cpu. It replaces the stock bracket and gives it more surface area to dissipate heat.
Great stuff love your videos !
unfortunately to expensive for me although i would love to have one ...
Question : could you do a Best Possible budget build for a Nuc based pc which could be sourced world wide ?
I would love some pointers from you ..
Thanks
In germany we say "Völlig sinnlos, aber geil!" ... keep up the good work😍
I've run into that with memory several time, even when you buy the exact DIMMs recommended by the MB maker, they often just done run stably at specified speed under load. I once bought a replacement mother board thinking I had a thermal issue and later discovered that there was a single bad row in a brand new DIMM when the new MB had the exact same symptoms of the old one. D'Oh
Good job!!!
Love your content, Dave! OMG, 1k watts. $10k😪
Nice - we need it to make the ‘one task per docker’ as fast as the ‘one thread per task’ was on the pentium.
If you worry about coolant leaks, use XSPC EC6 or one of the other waterless coolants. I've been using it for over 5yrs and I've even spilled some on a running graphics card without any effect beyond it leaving a sticky residue after wiping it off.
