Intel Engineer on: Die Thinning, CPU Thermals and Liquid Metal 

This is the type of content the internet needs, more engineers and less PR people. Keep the good content coming der8aur!!!!

Easily one of my favorite industry interviews in recent memory.

It's been a surprising change of methodology with Intel lately. Plant / manufacturing tours, engineers giving interviews and explanations if not how-to's, and just information in general being shared in a way that they'd NEVER been keen on previously. I love it! This kind of relationship with your buying public is exactly how you gain their trust and support. You're doing it right Intel! Didn't always, lol... used to be a VERY locked down company, one that used to share nearly nothing, with everything being confidential. This though.... this is good! And when you have quality assets in people as you clearly do, allowing them to speak, showing just how qualified and intelligent your employees are. That also goes a long way into gleaming trust in your company.

this guy was freaking awesome. great interview wish it was longer tbh

Video's like this and the one Steve from GN recently did with the cooler engineer of Nvidia really sets these channels apart. From the run of the mill "I do benchmarks so I'm a tech youtuber" channels that would never dare to do technical interviews like this. If you know your stuff you aren't afraid to talk with experts. Keep it up, and also kudo's to Intel for the behind the scenes access 👍

Der bauer should have a podcast where he invites engineers from intel, amd, nvidia and etc to talk a bit about what goes on behind the scenes. Would be really interesting.

As a materials science and engineering student, this interview was amazing. not only was it nice to finally understand the technical details (the electrical eng stuff is not my expertise lol), but Mike explained some maths-heavy concepts really well and his diagram and explanation of it were really easy to follow. You can tell you are both super interested in this topic! Please do more interviews with engineers! Learning about the technology, manufacuring, limitations (cost, reliability) etc is so important for understanding why products are made they way they are and perform they way they do.

Very interesting. I like the idea that intel have a whole team for each tiny part of the CPU even down to soldering team. Amazing.

thanks Mark! great to see engineers chatting and not PR teams interfering. enough info for enuthist without giving away secrets. nice

That was fascinating! More content like this please, it feeds that hunger for knowledge that so many of us engineering/physics overclockers simply can't satisfy any other way.

Excellent, Roman is experienced enough with the science and engineering to know what questions to ask and Mark is extremely intelligent and capable of simplifying the concepts to make it captivating. I loved this interview.

Talking to engineers is always fun. Every conversation is not wasted time as you always learn new and amazing things.

This is pure gold, great interview!

Great content, you don't often get this in-depth discussion with actual engineers... and no PR/marketing team involved. I never quite understood why the IHS made a return following the direct-die era of the late 90s/early 00s. I know it eases installation for OEM's and novices etc but it does seem to have been a consistent problem as far as cooling and as desktop chips seem to be reaching new record TDP's it seems like direct-die chip options could be something Intel/AMD could offer on certain product lines for enthusiasts or simply manufacturers that require the very best thermal performance. Obviously they don't want to honour warranty replacements to users who damage chips during installation but that wouldn't be expected and was never offered back when stock direct-die chips were a thing either.

For people interested, what he mentions is the Arrhenius equation, and there are other models of Accelerated Failure Time. The whole field is interesting

As someone who still plays on a 4790K (which has been heavily overclocked since day one), I greatly appreciate Intels research and testing team.

This type of more in depth engineer discussion is super interesting content. Props to intel for putting their engineers forward for this type of excellent content.

Please bring more content with engineers in the future if you can. It is really informative and gives a different but true perspective on many things which are otherwise only speculated and wrong in many instances!

Accelerated stability testing is super common in the pharmaceutical industry as well. When making a new drug, nobody knows the shelf life of either the active substance or the final product (e.g. tablets). So once they are reasonable confident the formulation development (e.g. tablet design + packaging) is over, they start accelerated stability testing of the batch intended for clinical trials. This has to be done to get estimate of what the drugs may look like 6 months or 1 year down the line, but you want to know within 3 months, so you can start the clinical trials as soon as possible. These are done at higher temperature and humidity (usually 40 °C and 75% RH) with periodic sampling to confirm whether the product still conforms to specification, such as active substance content, impurities, appearance and many more. If the accelerated tests pass, their results can be carefully extrapolated to 2× the accelerated test duration. So if your accelerated test shows no degradation after 3 months, you can be reasonably certain the drug is stable for 6 months. Of course, room temperature long-term stability testing is performed in parallel, because there's only so much the accelerated tests can do. So when you see shelf life indication on a drug box, its length was determined by long-term stability testing.

After working for some years supporting a fab NXP/Freescale/Motorola I really enjoy content like this sitting down with engineers picking their brains.

Not only refreshing and educating, but also the conversation felt good throughout with Mark. Loved it! Hoping to see more in the future! :)

I can always appreciate direct answers from tech manufacturers to let us know their perspective on design characteristics. Great video!

I’m so glad this information is public, thank you for doing this!

Great job! @der8auer EN Would be cool to get some more interviews with Mark in the future. Fun as well as educational to hear the insight and knowledge he has. Plenty more that people would love to hear from him if he's willing to do another interview in the future. Or just anyone else at all from Intel & AMD would be awesome. Longer interview would be even better, like an hour.

Amazing interview! I really like your content in the past 2 years or so. Especially visiting and interviewing experts (the electron microscope comes to mind) please do more of these if possible. I don't like videos often, as I use it as a playlist of stuff I want to show others or watch again. This has definitely earned a like :)

Absolutely fascinating, and I'm not a overclocker. Just the design diagram and what is allowed on camera is very informative in my opinion and if the desire ever is needed and let's face it if chips keep getting hotter then new answers are going to be needed before they burn through the silicon and leave a hole. But yeah thanks very informative

Absolutely incredible interview. Just superb. Thanks Mark!!!

This was a great interview. It is nice to hear the prospective of the people actually building the product. Thank you for putting this together.

I just bought a R16 with a i7 14700kf cpu and this put my mind at ease so much with temps. I've only ever seen mine get to the low 80s while gaming. Everywhere on the internet are people saying you need to be 60c max 70c for longevity and health. Ill listen to this engineer who went to school for this.

Awesome interview. 10:57 is so important--that's why I continually pick intel for my builds every 4-5 years. They just haven't had issues in my experience, even if they run hot. Love my 13900!

This was super interesting. Thanks for bringing us content like this and thanks to Mark for taking the time to sit down for the interview.

It's so much more interesting when an engineer is answering questions, they actually answer! PR People are a whole load of "I'll get back to you" and "I don't know if I can disclose that" and tangents about stuff they want to market. If an engineer goes on a tangent it's still interesting because it's actually related to the question.

Thought the thumbnail was Kingpin in a bad disguise. Enjoyed that, had to watch twice but was worth it. Great insight.

I've been watching your videos for a long time, today i finally subscribed, please keep it up and hope for more videos like this "behind the scenes"

This is what I come to RU-vid for! Love from Australia ❤

This is just awesome! You learn so much with every episode. Thanks Roman!

A very interesting and friendly conversation between two big experts, what a pleasure to watch this video, thanks to both of you guys!

excellent conversation. So many people complain chips aren't progressing fast enough and forget armies of engineers work their butts off to make it happen.

Super cool interview and nice to hear it straight from the engineers!

As someone who got into PC building and gaming over Covid, I didn't even know about the amount of interviews these channels made! This is so awesome!

It's crazy this dude came to the campus I work at! Super exciting to see people like Der8auer and Linus get videos of what happens inside the very labs I work daily in

Very nice interview. Would love to see more content featuring ppl who actually work in the field like this. Cheers!

Love these interviews that give an inside look at the manufacturing process

It is so nice to see people that put passion into their work instead of talking heads focused on manipulating public opinion. This interview and from other channels the engineer from Nvidia and the interview with JonnyGuru are the recent ones that I've watched and remembered that actually technology used to be fun, but it's hard to see nowadays behind the clouds of PR, claims and official statements of personnel not involved with the actual engineering work.

Awesome content. Mark seems like such a great guy, and explained everything in a great manner. Very insightful!

While I understand they can play around on the IHS to account the thickness variation of the die itself, so it fits on existing socket and cooling combo units, I wish they would offer a direct die product as they used to do back on the old days. As we've seen with custom kits, yours included, there are multiple benefits in using direct die cooling - with the drawback of less experienced users possibly cracking the die. Great discussion Roman.

Very insightful. I really appreciate the open discussion.

Absolutely loved this interview... More of this content or this type should I say... It's mind-blowing

Thank you for bringing us this awesome technical interview

Really awesome detail. Love it when the engineers get a chance to speak directly -- nothing lost in translation.

Welcome to the US for your visit, as always a great video.

Did not know Weird Al Yankovic is also an intel engineer! Jokes aside this was very useful information. Great content. Keep it up man!

Hope you enjoyed your visit to Oregon, Hillsboro off all places!

All power to you Mark, thank you for your service!

Thanks a lot for this content, it's refreshing to hear something from so close to the source.

So much more respect for the thought and work that goes into building a cpu

That was actually the most informative thermal dynamics conversation I have ever heard. 👏🏾👏🏾👏🏾

He did a great job explaining some of these concepts we heard about we didn't fully understand, especially, in my opinion, why CPU manufacturers don't just shave down their dies as much as possible on a technical level.

Great interview. Thank you!

This type of content must be the one that is uploaded to the internet, great job and excellent video.

Excellent combination of experts and youtuber, who knows how to arrange a video

Really pleased with these engineering interviews with Intel. Good job, keep them coming!

Wasn't really information I was interested in, but glad I watched this video. Really awesome info! Thanks!
