[SOLVED] AMD vs Intel temperature comparison

[Pee wee]

Hello friends!!

I hope you are all well!

I would like to know if it is true that in the past AMD always lost advantages over heat (thermal management). Why? Lifelong, when comparing an AMD micro vs. INTEL, the advantage was guaranteed in temperature, which over the years improved a lot. I think in the past both Intel and AMD have had heat problems. Many people believe that something is better than something else just because it's a certain brand.

Pls, what do you think about ...?

Thanks in advance.

AMD has no heat issues in the CPU department. a 3700X requires less power than an unlocked i5 and while it's idle temps are rather high the load temps are easy to manage. A 3950X with 16 cores uses 150W of power. that's 50W less than an i7-9700k.

Intel is exploiting their 14nm++++ process to an extent where they just pump power into these chips making them hot. their next node shrink will - hopefully - see a temperature decrease.

as for AMD's Bulldozer/Piledriver lineup... they went hot because AMD did basically what Intel is doing currently. raise the clock and pump power into them.

however as long as you have adequate cooling heat isn't really the main issue when comparing CPUs

The only reason AMD Ryzen runs "warm" so to speak is due to the 7nm process, the chips are very power efficient but due to everything being so close together, it is more difficult for the IHS to dissipate heat.

But it's really easy to fix, just make sure your thermal paste basically covers the entire IHS. Lots of people say add more than usual and that is true for Ryzen's case. With Intel you can get away with very little thermal paste.

The irony right now, is that Intel products usually run hotter than AMD. Especially since 10th Gen Intel CPUs push way more power vs their Ryzen counterparts (like RL said above).

@Isokolon, @TechyInAZ I am so grateful for your clarification and time. I really appreciate your comment. I love this forum & community.

Thank you ever so much! 👍

It's not intel pumping in the power, intel has pretty tame guidelines, which although still higher than ZEN are not all that crazy,if you follow intel's guidelines the 10900k should draw pl2 of 250W maximum for a maximum of 56sec which makes sense for workloads that the user has to sit in front of the computer and wait for,if you have to wait for 2-3 minutes for something to finish you will be glad if the CPU can use twice it's power budget to finish it in half the time and since it goes back to TDP afterwards the cooling can slowly dissipate that excess over time even if you only have a TDP cooler.
If you do something that takes 10hours (or a week) it will stay at PL1 of 125W for the whole duration except for the first minute,benchmarks will still show a max draw of 250W but over the whole duration of your workload it's going to be 125W exactly.

It's the mobo makers that take those defaults and increase them to infinity to look better against some other mobo,anadtech did a pretty good round up on it.

Also the same thing happened to ZEN although with a different technique.
ZEN depends on info from the mobo to determine how much power they draw and weather they should keep boosting or not and mobo makers take advantage of this by just saying that the power draw is lower than it actually is,the stilt found it out and you can see by examples how the readings from HWinfo actually show lower package power draw by messing with the setting.

Bottom line temp problems are almost always down to mobos screwing with settings to look better.
For intel they have to increase TDP to make them faster for ZEN they have to decrease TDP to make them faster.

Thank you for the clarification, @TerryLaze. You deserve an A!! I have learnt so much.

Kind regards 👍

Short answer Intel is raising the watts to get faster speeds, AMD is slower but use less watts.

Intel stoped including coolers on their overclocking processors, AMD includes one that is not really even adequate to get the max boost speed from the processor.

With adequate cooling neither have heat issues.
