  1. 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.

  2. Awesome vid, but i don't use your Liquid Metal called Conductonaut any more.. Had a lot of problems with it in laptops in particular, the surface of the copper or die going black on occasion. So I've switched to CoolLaboratory.. lol its also half the price and easier to apply!

  3. I would definitely like this type of content all day everyday. but my assumption is this type of content doesn't get as many views but it definitely attracts a very nerdy audience.
    if YouTube could get some way to monetize this content on its own merits then it's a viable long term piece of content.

    But if he does this every single day all day the audience and the creator both could get fatigue by listening. I am glad debauer has got a handle on this.

  4. I haven't delidded anything since probably 8th gen, I haven't delidded anything for my own personal use since 4th, but man every time I saw my 10850K throttle I thought about ordering a delid tool for LGA 1200. With my most recent upgrade though I made a decision I don't want to walk back on anytime soon, no more consumer grade chips with 20 ish PCIE lanes and Non-ECC memory.

    While the newest Xeons will probably always be firmly out of my grasp dealing with stability issues while my old Haswell E5 xeon server hums away in the other room is not something I'm willing to deal with anymore. I didn't even tune the 10850k it was at stock speeds with the RAM's XMP profile, at that point the K means nothing because it's not even cool on a 360mm radiator, the XMP profile means nothing because it's not even stable without manual tuning, so I gave in and got a used 3647 Xeon W. It's technically a performance loss sure, but getting it up and running and immediately putting it under equal or greater stress than I ever did my 10850 gave me no BSODs. I've decided in the same way enterprise buyers do that stability means more to me than bleeding edge speeds, because well sometimes the bleeding edge cuts you. Plus the single GPU already occupied every direct to CPU lane available to me which is annoying, there are other high speed connections I want to add, high speed networking, more robust I/O, NVME storage takes from lane count, and there's add in cards that I just want to experiment with; now I've got the bandwidth for it.

  5. Cool interview, but it seems like he didnt answer the ? as to why they dont shave it down and gave a generic answer that was basically “it depends on architecture and timeframes” which sounds like bs tbh, i think these engineers are too specialized and lazy in their efforts, just want to keep their cushy jobs without much thought or enthusiasm for making something optimal like they should be doing.
    This guys demeanor tells me this interview was probably the most difficult part of his career

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

  7. My suspicion has always been that Intel were concerned that if 9th Gen had massively improved thermals over 8th that it would have confirmed what so many critics of their switch to 'polymer' TIM from solder (in 2012 with 3rd Gen) had been saying ever since – "they did for no other reason than profit". Had 9th Gen used a thinner die (c. 0.6mm, as in subsequent nodes, and probably 2nd Gen/Sandy Bridge) with a thinner solder layer and people had seen a c. 15°C drop for the same vcore/clocks/power dissipation it would indeed have validated those criticisms. IOW, they deliberately nerfed 9th Gen.

  8. I still have my 9900k. I have all cores clocked up to 5ghz and it rarely gets up to 90C. Only if I'm doing some kind of crazy benchmark or workload it might go above 90C.
    When I'm gaming it runs fairly cool 55C-70C. I think they did a good job with that chip.
    I am using an all-in-one cooler with it.
    My 13700k on the other hand likes to hit 100C sometimes. That also has an all-in-one cooler.

  9. The thing that sad me the most is that I wouldnt want to be an intel engineer at the time where Intel was synonym of marketing, what a frustration to waste the talent of engineers just like him.

  10. This was epic. Love these technical insights not dumbed down and filtered by PR types.

  11. 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.

  12. I still have Intel CPUs from the very early 2000s that work as intended, in fact, in over 30 years I have only ever had one Intel chip fail, and it was entirely my fault because I pushed the chip too far without adequate cooling.

  13. This the kind of people I want to listen to about thermal solutions, not YouTubers who builds PCs that think they are smarter than engineers. 😉

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