  1. As long as you dont have all cores on max performance you dont have a valid result. Lower frequency is less heat. 9900k on 4,2 ghz is all kinds of wrong mine runs 4,7 on all cores all the time. Looks like your board has a avx offset run which with propper cooling should be off. Mce was off with mce on it can do all core 5ghz not a low 4.2. Looks like there was a hefty 500 mhz avx offset on. To me this is all kinds of flawed. Also on a non avx load the intel uses 35% less power so less heat. So heat output also depends on the load.

  2. Great comparison video! Those pyrex measuring jugs are god awful at accurately measuring the volume of liquid though, thinner the neck the better (e.g. measuring cylinder).

  3. hey linus, you get the whole thing wrong. There is a simple way to messure true TDP, you can just simply messure the power consumption. Because cpu take all the power to produce heat.

  4. I have seen many reviews where the ryzen cpus typically run cooler than the intel counter part. But from Tech Power Up's 3600 review, they say it runs hotter than a 9900K under a blender stress test. Although they use the same air cooler (Noctua NH-U12), i cant see how a 9900k runs cooler than a 3600. The problem i have with this is a lot of people like to quite these results when talking about temps between intel and AMD. I feel that something must be wrong here since many other tech reviewers report that the 9900k hits the 80s to 90s on a 240mm rad water cooler.

    Any thoughts?

  5. Why not just use a water block without cooling and measure the temp the coolant in the reservoir reaches after a set time, this method seems insane but guess it makes reasonable wtf TV.

  6. the chemical engineer viewers would tell you the best way would be to measure the temperature of the coolant in and out of the cpu block and if you know the flow rate you can calculate the heat transfer performance

  7. This was an actual terrible method, and probably a demonstration of what NOT to do, if you want to find out the true heat output of these CPUs.

    However, you used the same crappy method for both of them, and mostly seemed fair.

    Given this, it was actually surprising how close the 2 CPUs were, like it seems kinda irrelevant or at least secondary to worry about temps when trying to decide between the 2. Any half-decent quality cooler should be enough to keep them at safe temps, so it falls down to everything else, depending on the usage you want to do (gaming vs productivity and so on).

    Still waiting for a proper test methodology btw.
